Overview
The ARRMA BIG ROCK CREW 4X4 Cab Trimmed Body in Clear (Z-ARA-1381) is an exceptional replacement bodyshell designed for enthusiasts looking to customise their 1/10 scale RC monster truck. Whether you're a seasoned RC car UK competitor or a weekend basher keen to refresh your setup, this pre-trimmed clear body offers the perfect canvas for creating a truly unique custom painted look. The BIG ROCK CREW is one of ARRMA's most popular and capable 4WD monster truck platforms, and this official body shell is engineered to fit seamlessly with the hidden body mounting system found on BIG ROCK 4WD models.
Clear bodyshells are highly sought after in the RC off-road community because they allow you to display your custom paint job and graphics with stunning transparency effects and professional-grade finishes. Unlike painted bodies that come with a fixed colour scheme, this clear shell gives you complete creative freedom to design something truly personal to your RC vehicle. The BIG ROCK CREW body is particularly popular amongst UK RC enthusiasts because it combines aggressive styling with practical design — the cabin windows and bold proportions give it real visual impact whether you're racing at your local track or bashing in the garden.
ARRMA is a world-renowned manufacturer of high-performance RC vehicles and components, and every body shell they produce maintains strict quality standards. This particular shell comes complete with everything you need to get started on your custom paint project, including vinyl decals, pre-cut window masks and protective over-spray film. It's designed to fit directly onto your existing BIG ROCK 4X4 chassis without modification, making it an ideal upgrade for anyone wanting to breathe new life into their brushless RC monster truck.
Key Features
- Tough Polycarbonate Construction — The body is manufactured from high-quality polycarbonate material, which provides exceptional impact resistance and durability during rough off-road driving. This means your custom paint job is protected by a material that can withstand crashes, bash sessions and competitive track use without cracking or shattering like cheaper plastic alternatives.
- Pre-Trimmed for Rapid Installation — The body arrives pre-cut and trimmed to exact specifications, which means you can fit it to your BIG ROCK 4X4 chassis in minutes without needing to spend hours with hobby knives or trimming tools. This is a significant time-saver compared to untrimmed bodyshells and means you can focus on the creative aspects like painting and customisation rather than preparation work.
- Included BIG ROCK Vinyl Decal Sheet — A high-quality vinyl decal sheet is supplied in the box, featuring authentic ARRMA BIG ROCK branding and graphics that you can apply over your custom paint. These decals add professional detail and can be positioned exactly where you want them, allowing you to create a factory-quality finished appearance or customize the placement to your preference.
- Pre-Cut Vinyl Window Masks — Professional-grade, pre-cut vinyl masks are included for all windows and openings on the bodyshell. These masks make the painting process dramatically faster and easier by preventing overspray on the transparent window areas, resulting in clean, professional-looking windows with perfect masking lines every time. This is a feature normally only found on premium body kits.
- Protective Over-Spray Film — A protective film is included to shield areas during the custom painting process, further ensuring that your finished body looks factory-perfect without accidental paint drips or overspray marks that are difficult to remove. This demonstrates ARRMA's commitment to delivering a complete, professional painting solution.
- Compatible with Hidden Body Mount System — The body is specifically engineered to work with the hidden body mounting system used on 4WD BIG ROCK models, meaning it sits flush against the chassis and provides a seamless, integrated appearance. This hidden mounting design gives the finished truck a more authentic and professional look compared to visible body posts.
- Clear Shell for Custom Paint Potential — Unlike pre-painted bodies with fixed colour schemes, the clear shell gives you unlimited creative freedom to design custom paint schemes, graphics and effects. You can create anything from simple solid colours to complex metallic finishes, flames, racing stripes, scale detail painting or even airbrush artwork.
Technical Performance
This bodyshell is engineered to exacting standards by ARRMA for use on their 1/10 scale 4WD BIG ROCK platform, specifically the BIG ROCK 223S DSC models with brushless motors and hidden body mounting systems. The polycarbonate material provides the ideal balance of durability, flexibility and weight — robust enough to handle multiple crashes without catastrophic failure, yet flexible enough to absorb impacts without cracking. The pre-trimmed design means every window cut, panel line and mounting point is precision-cut at the factory to ensure perfect alignment with the BIG ROCK 4X4 chassis. The protective measures included — window masks, over-spray film and decal sheets — are professional-grade components typically found in premium RC body kits, indicating that ARRMA takes the custom painting experience seriously. For UK RC enthusiasts building their ideal brushless RC monster truck, this body shell represents excellent value when you consider the included accessories and the engineering quality that goes into ARRMA chassis development and body design.

Frequently Asked Questions
- Which BIG ROCK models does this body shell fit? — This bodyshell is compatible with the ARRMA 1/10 BIG ROCK 223S DSC 4X4 RTR brushless monster trucks. Specifically, it fits the following models: C-ARA4312V4T1 (Black), C-ARA4312V4T3 (Blue), and C-ARA4312V4T2 (Green). The hidden body mounting system on these models means the shell will integrate perfectly without any modification needed.
- Do I need any tools to fit this body to my BIG ROCK 4X4? — The body is pre-trimmed and ready to install, so you should not require extensive modification. You may need basic hobby tools to secure the body clips to your existing chassis, but the design is straightforward and fitting should take only a few minutes if you're already familiar with your BIG ROCK model.
- Is this body clear for painting or is it already finished? — The bodyshell arrives completely unpainted in clear polycarbonate. This is intentional — the clear finish gives you the opportunity to create a custom painted design. The included window masks, over-spray film and vinyl decals support the entire painting process from preparation through to finishing, making this an all-in-one custom painting solution.
- What paint should I use on a polycarbonate RC body? — Most RC enthusiasts use polycarbonate-compatible spray paints or specialized RC body paints, which adhere properly to polycarbonate without cracking or peeling. Always check that your chosen paint brand is suitable for polycarbonate, as some standard spray paints can cause the material to become brittle. Multiple thin coats are better than one thick coat.
- How durable is this clear body in off-road conditions? — Polycarbonate is significantly more impact-resistant than standard plastic, making it ideal for bashing and off-road use. However, repeated hard crashes can eventually cause damage. The material flexibility means it often survives impacts that would crack or shatter cheaper bodyshells, but severe crashes may require body replacement eventually depending on the severity.
- Can I use this body with my custom paint scheme? — Yes, absolutely. The clear shell is designed specifically for custom painting. You have complete creative freedom to create any paint design you want. The included window masks ensure clean painting of the window areas, and the over-spray film helps you achieve a professional-looking result without accidental paint on protected areas.
- Are the included vinyl decals necessary? — The vinyl decal sheet is included as an optional finishing touch. You can use the decals to add authentic ARRMA branding or custom graphics over your paint job, or you can skip them entirely if you prefer a plain custom painted look. The choice is entirely yours.
- What is the scale of this body shell? — This is a 1/10 scale bodyshell, meaning it's proportionally one-tenth the size of a real full-size truck. The BIG ROCK CREW body is designed to look like a modern full-size crew cabin pickup truck in this 1/10 scale.
