Key Features

• Red Anodised Aluminium Construction — The cover is manufactured from anodised aluminium, providing superior strength and durability compared to plastic alternatives whilst resisting corrosion and wear from outdoor RC driving. The bright red finish is both eye-catching and protective, making your Grom stand out in any RC collection.
• EXB-Style Appearance — This upgrade grants your Grom the distinctive EXB aesthetic, a sought-after look amongst RC car enthusiasts in the UK who appreciate premium chassis upgrades. The visual enhancement immediately upgrades the perceived quality of your vehicle.
• Increased Upper Arm Pin Mount Support — Beyond cosmetics, this cover reinforces the upper arm pin mount area, a critical stress point during aggressive driving. This additional structural support helps prevent flex and potential damage during high-impact bashing or competitive racing sessions.
• Drop-In Compatibility — Designed specifically for the ARRMA Grom, installation requires no complex modifications. The cover integrates seamlessly with your existing chassis, making it suitable for drivers of all experience levels, from beginners exploring RC upgrades to seasoned competitors fine-tuning their setups.
• Premium Finish Quality — The anodised aluminium surface provides a clean, high-quality appearance that complements modern RC car aesthetics. This attention to detail matters when you're investing in your RC hobby and want components that reflect genuine craftsmanship.

Technical Performance

The RC Overhaul Rear Gearbox Cover represents thoughtful engineering in response to real durability challenges faced by Grom drivers. Constructed from anodised aluminium—a material choice that balances weight efficiency with exceptional strength—this component provides measurable reinforcement without adding excessive mass to your chassis. The anodising process creates a protective oxide layer on the aluminium surface, enhancing corrosion resistance and ensuring the red finish remains vibrant through repeated use and exposure to outdoor conditions. Unlike injection-moulded plastic covers that can flex under load or become brittle over time, this aluminium construction maintains structural integrity even during extreme bashing sessions. The precision engineering means the cover aligns perfectly with Grom-specific mounting points, including the critical upper arm pin mount area. This targeted reinforcement addresses a known stress concentration point where many drivers experience wear or potential failure during aggressive driving. The increased support translates to reduced deflection in the chassis frame during hard cornering, jumps and high-impact landings—precisely the scenarios where RC drivers in the UK demand reliable performance. For anyone serious about protecting their investment and maximising their Grom's lifespan, this upgrade provides tangible benefits beyond visual enhancement.

Frequently Asked Questions

• Is the RC Overhaul Rear Gearbox Cover suitable for beginner RC drivers? — Absolutely. This is an ideal first upgrade for Grom owners because installation is straightforward and requires no specialist tools or technical knowledge. Beginners exploring RC upgrades in the UK will appreciate how this component improves durability without introducing complexity. It's a confidence-building upgrade that makes an immediate visual and functional difference to your vehicle.
• What exactly is anodised aluminium and why does it matter for RC car parts? — Anodising is an electrochemical process that creates a protective oxide layer on aluminium surfaces. This layer makes the material significantly harder, more corrosion-resistant, and longer-lasting than bare aluminium or plastic. For RC cars exposed to dirt, moisture and impact forces, anodised aluminium components simply outlast alternatives, making them worth the investment for drivers serious about durability.
• Will this cover fit my ARRMA Grom? — Yes. The RC Overhaul Rear Gearbox Cover (part number G-RCO-AR029R) is engineered specifically for ARRMA Grom models and provides drop-in compatibility. No modifications to your chassis are required, though some drivers may need to remove the existing plastic cover first—a simple task requiring basic tools.
• Does this upgrade improve performance or just appearance? — While the red anodised finish undoubtedly enhances your Grom's visual appeal, the functional benefits are equally important. The increased support for the upper arm pin mount directly addresses a stress concentration point, reducing deflection and potential damage during aggressive driving. Many UK RC drivers report improved chassis rigidity and confidence in their vehicle's durability after fitting this upgrade.
• What is the upper arm pin mount and why does additional support matter? — The upper arm pin mount is the connection point between the upper suspension arm and the chassis. During cornering, jumping and impact events, significant forces concentrate at this location. By providing increased support, this cover minimises flex in the chassis frame, which can otherwise accumulate stress and eventually lead to cracks or failures. Additional support at this critical area is particularly valuable for drivers who bash hard or compete frequently.
• How does this compare to plastic gearbox covers? — Anodised aluminium offers superior strength, durability and corrosion resistance compared to plastic covers. Plastic can flex under load, become brittle with age and UV exposure, and eventually crack or fail. Aluminium maintains structural integrity indefinitely, requires no maintenance, and won't degrade from exposure to outdoor elements. For RC enthusiasts in the UK investing in upgrades, aluminium components offer better long-term value.
• Is this part available in stock at RC Model Shop? — Yes, the RC Overhaul Rear Gearbox Cover (G-RCO-AR029R) is in stock and typically ships the same day. RC Model Shop offers free UK delivery on orders over £100, making this an affordable upgrade to add to your next purchase.
