The body shell is the most replaced part on any Arrma Infraction. Street bashing is uniquely brutal on polycarbonate — asphalt grinds, curb strikes crack, and high-speed traction rolls send your shell sliding across pavement like a cheese grater at 60 mph. Whether you need a stock replacement, want to go full custom paint, or are just trying to make your current body survive more than two sessions, this guide covers every option across both the 3S and 6S platforms — plus how to actually make them last.

Infraction 3S vs 6S Bodies — They’re NOT Interchangeable
Before anything else: the 3S and 6S use completely different body shells. This trips up more people than you’d think. I made this exact mistake early on — ordered a 6S body thinking it would drop right onto my 3S chassis. It arrived three days later, and I had a polycarbonate shell the size of a serving platter sitting on my workbench next to a car roughly 28% smaller in every dimension. Total waste of $110 and return shipping. Don’t be me.
The difference isn’t just fitment — it’s a totally different scale:
| Spec | Infraction 3S BLX | Infraction 6S BLX |
|---|---|---|
| Scale | 1/8 | 1/7 |
| Wheelbase | 335mm (13.19”) | 406mm (15.98”) |
| Overall length | 562mm (22.13”) | 695mm (27.36”) |
| Overall width | 257mm (10.12”) | 310mm (12.2”) |
| Body part # prefix | ARA414xxx | ARA410xxx |
| Stock body price range | $66–$84 | $105–$111 |
A 71mm wheelbase gap and completely different body post positions mean no 6S shell will ever physically mount to a 3S chassis — and vice versa. Always cross-reference the part number prefix: ARA414xxx = 3S, ARA410xxx = 6S. Get it wrong and you’re eating return shipping both ways.
Not sure which Infraction you need a body for? Our Infraction 3S vs 6S comparison breaks down the differences in full detail, including performance, pricing, and which one makes sense for your use case.
Stock Replacement Bodies
Infraction 3S Stock Bodies
The Infraction 3S currently has five stock body options from Arrma, all in polycarbonate (Lexan), all pre-trimmed with body post holes already drilled. They ship ready to bolt on — no cutting required.
The two flagship V3 BLX bodies match the RTR color options exactly. The Black/Gold (ARA414007) and Black/Teal (ARA414008) both retail at $83.99 and arrive pre-painted, pre-decaled, and pre-trimmed. These are the highest-fidelity replacements if you want your car looking stock.
If you want to save a few bucks, the MEGA-variant bodies — ARA414001 and ARA414005 (both $71.99) — are designed for the brushed Infraction MEGA but mount identically on the 3S BLX chassis. The platform is shared, so fitment is perfect. For a basher who’s just going to trash it in three weeks anyway, saving $12 per shell adds up.
Finally, the clear body (ARA414002, $65.99) is the starting point for every custom paint job on the 3S. It comes with an Infraction vinyl decal sheet, but the body itself is completely unpainted — prime real estate for Tamiya PS spray cans.
| Part # | Color/Style | Price | Type |
|---|---|---|---|
| ARA414007 | Black/Gold (V3 BLX) | $83.99 | Pre-painted |
| ARA414008 | Black/Teal (V3 BLX) | $83.99 | Pre-painted |
| ARA414001 | MEGA original livery | $71.99 | Pre-painted |
| ARA414005 | MEGA alternate livery | $71.99 | Pre-painted |
| ARA414002 | Clear with decals | $65.99 | Clear/unpainted |

When in doubt, go stock — the fit is guaranteed, the graphics look great, and you never have to guess about body post compatibility.
Infraction 6S Stock Bodies
The 6S stock lineup is more expensive by roughly 30% — you’re paying for a significantly larger 1/7-scale shell. Current options run $105–$111 at AMain Hobbies, though RC Planet occasionally has them discounted when in stock.
The two current pre-painted options are Blue/Red (ARA410005, $110.99) and Silver/Red (ARA410006, $110.99), matching the V2 RTR colorways. The original Matte Bronze Camo (ARA410002) from the V1 era is still floating around at some retailers for around $92 — a legitimately good deal if you can find it.
The clear body (ARA410001, $104.99) is the one to get if you plan on custom painting. It fits both V1 and V2 chassis variants, includes decals, and arrives pre-trimmed. This is also the base shell most aftermarket body builders use as a reference for fitment, so it’s your safest starting point for experimenting with position mods.
A word on the limited-edition NASCAR bodies: Arrma released three over the years — the No. 38 Ford Truck (ARA410016, 1,500 units), the No. 34 Ford Mustang NASCAR Cup Series (ARA410017, 1,200 units), and the 2023 No. 38 Teal F-150 (ARA410018). All are effectively unobtainable at retail now. If you see them on eBay, expect to pay well above original retail. They’re collector pieces at this point — not practical basher shells.
| Part # | Color/Style | Price | Type |
|---|---|---|---|
| ARA410005 | Blue/Red (V2 BLX) | $110.99 | Pre-painted |
| ARA410006 | Silver/Red (V2 BLX) | $110.99 | Pre-painted |
| ARA410002 | Matte Bronze Camo (V1) | ~$92–$111 | Pre-painted |
| ARA410001 | Clear with decals | $104.99 | Clear/unpainted |

Aftermarket & Custom Bodies
Pre-Painted Aftermarket Bodies
The pre-painted aftermarket scene for the Infraction 6S is surprisingly deep. Bittydesign leads the charge here with their P-GT3R (BDYAR7-PGT3R) — a Porsche GT3-inspired shell available in both clear and pre-painted white/red versions for around $105–$110. It’s a direct fit for the Infraction V2 and comes with a front splitter and rear wing pre-installed. If you want to run something that looks sharp without touching a can of paint, this is the move.
PROTOform (the RC body division of Pro-Line) offers pre-painted versions of several of their licensed shells — including the Nissan Skyline GT-R R34 in Bayside Blue (PRM158413, ~$106). Bayside Blue on a 1/7-scale R34 looks incredible in person. It’s the JDM community’s go-to choice and legitimately turns heads at the park.
For the Infraction 3S, pre-painted aftermarket options are more limited. PROTOform offers the 2021 Ford Mustang GT in Metallic Blue (PRM158213, ~$79.99) for the Vendetta/Infraction 3S platform. It requires repositioning the front and rear body posts slightly, but fitment is otherwise clean.

Clear Bodies (Paint Your Own)
This is where the real fun starts — and where the Infraction community particularly shines. The variety of clear body options available for the 6S platform is genuinely impressive.
I grabbed a clear ARA410001 last year and went with a matte black hood and roof, candy red side panels, and a gold metallic splitter and wing — full Hoonigan-vibes livery. Two cans of Tamiya PS and about three hours of masking tape work. The result looked ten times better than any stock graphic, and when it inevitably met a curb at 55 mph two months later, I was already looking forward to painting the next one. That’s the magic of clear bodies: the crash stops hurting when the replacement canvas is already waiting.
For the Infraction 6S (1/7 scale), the best clear body options:
PROTOform makes three licensed clear shells that are direct fits or near-direct fits:
- 2002 Nissan Skyline GT-R R34 (PRM158400, ~$64.99) — The community JDM favorite. Direct fit for the Infraction 6S. Includes front splitter, rear wing, Nismo decal sheet. Officially licensed by Nissan.
- Dodge Challenger SRT Demon (PRM158600, ~$84.99) — Available on Amazon →. Direct fit for Infraction 6S. The muscle car that the community has been waiting for. Requires ARA320357 body posts purchased separately.
- Chevrolet Corvette C8 (PRM157700, ~$84.99) — Available on Amazon →. Designed for Felony and Infraction 6S. Minor rear fender clearance adjustment may be needed.
Bittydesign offers arguably the widest 6S selection, all in 1.5mm genuine Lexan polycarbonate at $85–$116:
- Destroyer (BDYMC7-DSTY, ~$85–$100) — Muscle car silhouette with a removable 3D front nose piece. Direct fit for Infraction 6S.
- JOTA (BDYGT7-JTA, ~$100–$111) — Lamborghini Aventador-inspired. Designed for Felony; fits Infraction with minor post adjustment.
- Seven65 (BDYGT7-S65, ~$95–$116) — McLaren GT3-inspired. Probably the most visually aggressive option on the list.
For the budget-conscious, Delta Plastik USA (deltaplastikusa.com) offers 10+ designs for the 6S platform starting at just $14.99 — using 2mm Lexan (thicker than any competitor). The CR8 Corvette C8 at $14.99, Porsche 917 at $20, and Jaguar XRS Li at $15.99 are popular choices. No frills, no fancy wings, but the thick polycarbonate makes them the durability kings for speed run setups.
For the Infraction 3S (1/8 scale):
- PROTOform 2023 Nissan Z (PRM158300, ~$50–$60) — Clear only. Fits Vendetta and Infraction 3S. Classic JDM silhouette.
- PROTOform 2021 Ford Mustang GT (PRM158200, ~$49.99) — Clear body for Vendetta/Infraction 3S. Budget-friendly option with a recognizable muscle car shape.
- Bittydesign Divina (BDAR8-DIV, ~$65–$90) — Bugatti Chiron-inspired, designed for the Vendetta/Infraction 3S platform.
Recommended paints for polycarbonate bodies:
Always paint from the inside of the shell in reverse order — details first, dark colors last, opaque backer coat as the final layer. Use only polycarbonate-specific paint; regular spray paint cracks and flakes on Lexan after the first flex.
- Tamiya PS spray paint series → — The universal go-to, ~$6–$8/can. 60+ colors, excellent adhesion, fuel-proof. Two cans typically cover a 6S shell.
- SpazStix — For color-shifting holographic and chameleon effects. Available in aerosol and airbrush.
- Createx Wicked Colors — Community favorite for airbrushing, especially for detailed multicolor liveries.
Vinyl Wraps
Full pre-cut body wraps specifically for the Infraction shell don’t exist as a commercial product — yet. What does exist is a strong market in chassis skins and vinyl sheet work.
Darkside Studio Arts LLC is the dominant brand for Infraction-specific vinyl. Their chassis wraps for the 6S/Limitless platform run $44.95–$59.95 in designs like Dirty Bird, Marked Up, and The Outlaw — 15–25 mil X-Treme vinyl with metallic and chrome finishes. Truline Graphics offers die-cut Infraction/Limitless chassis skins at $34.95. These protect the aluminum chassis from rocks and debris rather than the body shell itself, but they add a significant aesthetic upgrade.
For full body vinyl customization, the community uses generic automotive vinyl sheets cut to fit: 3M 2080 Series, Avery Dennison SW900, and ORACAL 970 RA are the most popular choices at $5–$20 per sheet — enough to cover a full RC body with careful cutting. Custom digital-printed wraps from services like Rvinyl.com are available but run $185–$350.

Wraps have real advantages over paint: instant reversibility (peel it off with no damage), zero cure time, added scratch protection as an extra polycarbonate layer, and essentially unlimited design options from any print shop. The trade-off is that complex body contours are harder to conform vinyl to than flat panels. For more on vinyl application techniques, our RC drift stickers & livery guide covers waterslide decals and wraps in detail.
Can You Fit Other Arrma Bodies on the Infraction?
Good news: within each scale, there’s meaningful cross-compatibility in the Arrma on-road lineup.
Infraction 3S ↔ Vendetta 3S: These two share the same chassis platform. Body swaps are nearly plug-and-play — you’ll need to reposition the body posts and swap the front foam bumper/splitter piece, but fitment is otherwise clean. This gives 3S owners access to the Vendetta body catalog, including the PROTOform Mustang GT that lists “Vendetta” as its primary platform. The Arrma Vendetta 3S shares on-road DNA — check if its body is cross-compatible with whatever specific shell you’re eyeing.
Infraction 6S ↔ Felony 6S: Partially compatible, but more involved. Both run the 1/7-scale platform, which is why aftermarket manufacturers like PROTOform and Bittydesign often list “Felony/Infraction” compatibility on the same shell. The complication: the Felony uses larger staggered rear tires with different rear diff gearing. Running a Felony body on a stock Infraction chassis leaves the rear wheel wells looking undersized unless you also swap to Felony rear tires and diff components. It can be done — many builders have done it — but budget for more than just the body shell.
Infraction 6S ↔ Limitless: Similar story. The Limitless is essentially a tuned version of the same platform. Body swaps work, but body mount positions and front bumper configurations differ enough to require some fabrication.
The short answer: 3S owners should always check Vendetta compatibility, and 6S owners can often use Felony-spec aftermarket bodies with minor adjustments. Bodies labeled exclusively for Infraction 6S will fit perfectly stock.
How to Make Your Infraction Body Last Longer
Pre-Run Reinforcement (BEFORE the First Run)
I reinforce every body before it ever hits pavement. The extra hour of prep work has saved me dozens of replacement shells over the years. My first Infraction body lasted about three weeks before the front end started looking like it lost a fight with a belt sander. Asphalt is in a completely different category of abuse than dirt — it abrades, it grinds, and it doesn’t forgive. Now I do the full Shoe Goo treatment before the protective film even comes off, and my bodies last months instead of weeks.
The community gold standard: fiberglass mesh tape + Shoe Goo
This is the technique you’ll find recommended on every Arrma forum thread about body reinforcement. It works by creating a composite laminate on the interior of the shell — similar in concept to fiberglass-reinforced plastic.
- Clean the interior with rubbing alcohol and let dry completely
- Apply self-adhesive fiberglass drywall mesh tape (grid-type, not paper drywall tape) across the entire interior in strips
- Tack in place with small hot glue dots
- Wearing nitrile gloves, spread Shoe Goo through the mesh with your fingers, filling all crevices
- Allow 24 hours between layers — do this outdoors, the fumes are intense
- Apply at minimum two full layers, with triple coverage on body post hole areas, front corners, and rear wing mount points
- Optional: finish with 5–6 coats of Rustoleum spray-on bedliner for added abrasion resistance
An upgraded variant uses 0.1mm fiberglass cloth instead of drywall mesh (about $10 for 40 sq ft on Amazon). It soaks Shoe Goo better, conforms to curves, and produces a stronger composite. Community members who’ve tried both consistently rate it as superior.
Fiberglass reinforcement tape →
For quick protection without the full treatment, Gorilla Tape or T-Rex tape on flat interior panels (roof, hood, doors) offers reasonable impact resistance and takes about five minutes.
Body Clip & Mount Upgrades
Standard bent-wire body clips are functional but fiddly, especially when you’re field-swapping a body after a crash. A few upgrades dramatically improve the mounting experience:
Body hole reinforcement washers are the single most impactful cheap upgrade. The #1 body failure point on every Infraction is the mounting holes tearing out — standard clips concentrate stress on a tiny perimeter of polycarbonate that eventually cracks through. Nylon washers on both sides of the hole distribute that stress across a larger surface area.
RC body hole reinforcement washers →
R-pins body clips → — R-pins are harder to lose in the field than standard clips and less likely to come undone mid-run.
Fine Laser Designs Clipless Body Mounts (LAS23133) — A twist-lock system (90° rotation to lock/unlock) that works on both the 1/8 and 1/7 Infraction. No chassis modification needed. Available at AMain Hobbies and HobbyTown. Eliminates clip fumbling entirely.
Magnetic body mount systems — Custom 3D-printed mounts using countersunk rare earth magnets (typically 12 total in 6 pairs). Community builds have tested these to 130+ mph on speed run setups. Worth noting that extreme air draft can potentially lift bodies at top speed, so this is more of a casual basher upgrade.
Repairing Cracks & Damage
Not every cracked body needs to be binned. Small cracks and tears are repairable, and a repaired body can often survive many more sessions before needing full replacement.
For small hairline cracks, apply a drop of thin CA glue (super glue) to the crack from the inside and let capillary action pull it in. Once cured, reinforce with a patch of drywall mesh tape and Shoe Goo over the repair area.
For larger tears and splits, Shoe Goo is the go-to. Apply generously to both sides of the tear from the interior, press together, and clamp for 24 hours. The bond is flexible — it won’t re-crack from flex the way CA glue alone would.
The honest answer on when to repair vs replace: if the mounting hole areas are torn out or if the structural integrity of the body is compromised (cracked across major panels), replace it. A body that can’t hold clips reliably is a liability at speed — you don’t want a shell pinwheeling off at 70 mph.
Street Bashing Body Survival Tips
Asphalt is categorically harder on RC bodies than dirt, grass, or gravel — and understanding why helps you drive more intelligently and spend less on replacement shells.
Dirt is soft and forgiving. When you crash on dirt, the car digs in and slows quickly. On asphalt, there’s no give — the car slides, tumbles, and grinds across an abrasive surface at full speed. The traction roll is the Infraction’s signature crash mode: at high speed, one side catches traction, the car flips sideways, and the body slides 30–50 feet along the pavement. That’s pure abrasion damage that no amount of Shoe Goo prevents.
Curb strikes are the #1 cause of catastrophic body damage on street bashers. A direct hit on a concrete curb at anything above 30 mph can split a body in one shot. Being aware of curb proximity and giving yourself exit room is better protection than any reinforcement technique.
Low-speed impacts vs high-speed slides: counterintuitively, low-speed impacts often cause more localized structural damage than high-speed slides. A 5 mph direct hit on a pole stresses a single point. A 50 mph traction roll distributes the impact energy across a large surface. Both are bad, but they fail the body in different ways.
If you bash hard weekly, plan your body budget accordingly. Even with full Shoe Goo reinforcement, a stock shell under serious weekly use will need replacement every 2–4 months. The delta between a $65.99 clear 3S body and a $14.99 Delta Plastik 6S body starts to matter when you multiply it by 4 replacements a year.

FAQ
Q: How long does an Arrma Infraction body last?
It depends almost entirely on driving style and terrain. On smooth pavement at moderate speeds with no crashes, a reinforced body can easily last 6+ months. Hard street bashing with regular traction rolls and occasional curb strikes will wear through an unreinforced stock body in 2–4 weeks. With full Shoe Goo and fiberglass mesh reinforcement, expect 2–4 months of weekly hard use before replacement. Plan to reinforce every body before first use and budget for 3–4 replacements per year if you bash weekly.
Q: Are Infraction 3S and 6S bodies interchangeable?
No — absolutely not. The 3S is 1/8 scale with a 335mm wheelbase; the 6S is 1/7 scale with a 406mm wheelbase. The size difference, body post positions, and mounting dimensions are completely incompatible. Always verify the part number prefix: ARA414xxx for 3S, ARA410xxx for 6S.
Q: Can I use a Felony body on an Infraction chassis?
Partially. The Felony 6S and Infraction 6S share the same 1/7-scale platform, and many aftermarket manufacturers list both as compatible. However, the Felony uses larger staggered rear tires with different differential gearing. Running a Felony body on a stock Infraction 6S leaves the rear wheel wells looking undersized unless you also swap to Felony rear tires and rear differential components. For aftermarket bodies that list “Felony/Infraction” compatibility, the swap is typically manageable with minor body mount adjustments.
Q: What’s the best way to reinforce an RC car body?
The community gold standard is the fiberglass mesh drywall tape plus Shoe Goo laminate applied to the interior before first use. Apply at minimum two layers, with triple coverage on body post holes, front corners, and rear wing mount points. Allow 24 hours cure between layers. As a complement, use nylon body washers on both sides of every mounting hole — these prevent the most common failure point (holes tearing out). For quick reinforcement, Gorilla Tape on flat interior panels provides reasonable protection with minimal effort.
Q: Where can I buy custom Infraction body wraps?
For chassis skins, Darkside Studio Arts (darksidestudioarts.com) and Truline Graphics (trulinegraphics.com) make the best Infraction-specific vinyl wraps at $35–$60. For full body customization via vinyl, generic automotive sheet vinyl from brands like 3M 2080 Series, Avery Dennison SW900, or ORACAL 970 works well at $5–$20 per sheet — enough to cover a full body. Custom digital-printed wraps can be ordered from services like Rvinyl.com but run $185–$350. You can also search Amazon for RC Infraction vinyl wrap options →.
Conclusion
For the 3S, your options are solid but limited: stock shells from Arrma or clear bodies from Arrma and PROTOform for custom painting. For the 6S, the ecosystem is genuinely deep — Arrma’s stock shells, PROTOform’s licensed vehicles (Skyline R34, Challenger SRT Demon, Corvette C8), Bittydesign’s Italian supercar designs, and Delta Plastik’s ultra-thick budget bodies all give you real choices at every price point. Whichever direction you go, reinforce before you run and budget for the inevitable replacement — that’s just street bashing reality.
If you need a starting recommendation: for most 6S bashers, the Arrma clear body (ARA410001) plus a $7 can of Tamiya PS-5 black and a $7 can of your accent color is the sweet spot. You get a fully custom-looking car, you’re not heartbroken when it gets trashed, and the next custom paint job is already something to look forward to.
