Key Features
- CNC Machined Aluminium Construction — This component is precision-manufactured from high-grade aluminium using CNC (Computer Numerical Control) technology, ensuring perfect tolerances, consistent quality and superior strength compared to injection-moulded plastic. Aluminium is significantly more rigid than plastic, which means less flex under acceleration and better structural integrity during high-impact impacts common in off-road RC bashing.
- 2-Piece Design for Easy Assembly and Maintenance — The motor mount and gearbox case are engineered as two separate pieces, making them simpler to assemble, adjust and maintain. This modular approach allows you to access internal components without complete disassembly, saving you time during repairs and upgrades.
- Improved Heat Dissipation — Aluminium conducts heat far more efficiently than plastic, actively drawing thermal energy away from your motor during extended running sessions. This keeps motor temperatures significantly lower, allowing you to run harder for longer without thermal throttling or component degradation. Lower motor temperatures mean improved reliability and extended lifespan of your brushless motor and ESC.
- Red Anodised Finish — The protective anodised coating provides superior corrosion resistance compared to bare metal or painted finishes, ensuring the component maintains its appearance and structural integrity even after exposure to dirt, water and the elements. The vibrant red colour adds visual appeal when fitted to your Arrma 4S platform, complementing the truck's aggressive design.
- Direct Replacement for Stock Components — This component is engineered as a perfect drop-in replacement for the plastic motor mount and gearbox case fitted to stock Arrma 4S vehicles. No modifications, drilling or custom fabrication is required — simply remove the old plastic parts and install this aluminium upgrade using the existing mounting points and fasteners.
- Enhanced Durability and Rigidity — The increased structural stiffness provided by aluminium construction translates directly into improved handling consistency, better power delivery transmission and reduced flex during cornering and acceleration. Your Arrma will feel noticeably more planted and responsive after this upgrade.
- Professional Upgrade for Serious Bashers — This is the type of component chosen by experienced RC enthusiasts who understand that small details compound into significant performance and longevity gains. It represents the philosophy that quality upgrades in critical areas deliver real-world improvements in reliability and driving experience.
Technical Performance
The RC Overhaul Motor Mount & Gearbox Case represents a quantum leap in build quality compared to the standard plastic components found in stock Arrma 4S vehicles. Manufactured from premium aluminium using CNC machining technology, this component delivers engineering precision that injection-moulded plastic simply cannot achieve. The material choice is significant: aluminium offers approximately three times the strength-to-weight ratio of the standard plastic, meaning you gain durability without adding appreciable mass to your vehicle's chassis. The anodised coating adds an additional layer of protection against corrosion, UV damage and mechanical wear, ensuring the component maintains its structural integrity and appearance through countless bash sessions. For RC car enthusiasts in the UK who run their vehicles in varied conditions — from dusty summer tracks to muddy winter courses — the enhanced corrosion resistance of anodised aluminium is a substantial practical advantage. The improved heat dissipation characteristics of aluminium are particularly valuable during extended running sessions, where motor temperatures can climb dangerously high with plastic housings. By actively conducting heat away from the motor windings and bearings, the aluminium construction helps maintain optimal operating temperatures, reducing thermal stress on your brushless motor and electronic speed controller. This extends the lifespan of these expensive components and maintains consistent power delivery throughout your driving session. The 2-piece design allows for easier access to internal gearbox components during maintenance and repairs, reducing the time and frustration associated with servicing your Arrma 4S.

Installation and Setup
Installing the RC Overhaul Motor Mount & Gearbox Case is straightforward for anyone with basic RC maintenance experience. The component is engineered as a direct replacement for your Arrma 4S's stock plastic motor mount and gearbox case, meaning it uses the existing mounting points and fasteners on your chassis. No drilling, cutting or modification of the chassis is required. Simply remove your old plastic components, inspect the mounting area for debris, and install the new aluminium case using the original hardware. The process typically takes 15-30 minutes depending on whether you're removing other components for full access. Once installed, no additional adjustment or tuning is necessary — the component will function immediately as a drop-in replacement whilst delivering the performance and durability benefits of precision-engineered aluminium construction.
Frequently Asked Questions
- Will the RC Overhaul Motor Mount & Gearbox Case fit my Arrma 4S model? — Yes, provided your vehicle is listed in the compatibility section above. This includes the Arrma Kraton 4S V2 (both green and standard versions), the Arrma Mojave 4S (both blue and white versions) and the Arrma Outcast 4S V2 (both red and gunmetal versions). These are the primary Arrma 4S platforms for which this component is engineered as a direct replacement. If you own a different Arrma 4S model not listed, contact our team at RC Model Shop for verification before ordering.
- What is the performance difference between this aluminium case and the stock plastic one? — The aluminium case delivers three main performance advantages: significantly improved heat dissipation that keeps motor temperatures lower during extended running, enhanced structural rigidity that reduces flex and improves handling consistency, and dramatically superior durability that protects against the impacts and vibrations of off-road RC bashing. You'll notice your vehicle feels more responsive and planted, runs cooler, and maintains performance consistency across longer driving sessions.
- Is this case difficult to install on my Arrma 4S? — Installation is straightforward for anyone with basic RC maintenance skills. The component is a direct replacement for the stock plastic parts and uses all existing mounting points and fasteners — no modifications to your chassis are required. The process takes approximately 15-30 minutes and requires only standard RC tools such as hex drivers. Full assembly instructions are provided with the component.
- Will upgrading to this aluminium case improve my vehicle's speed or acceleration? — This component is not designed to increase top speed or acceleration directly. Instead, it improves heat management, structural rigidity and durability. The real benefit is that by running cooler and with less mechanical flex, your motor and ESC will maintain more consistent performance throughout your driving session, and the overall handling response will feel sharper and more planted. You may notice subjectively snappier throttle response due to reduced chassis flex.
- How does the anodised finish protect the aluminium? — Anodising is an electrochemical process that creates a thick, protective oxide layer on the surface of the aluminium. This coating resists corrosion from salt water, mud, moisture and UV exposure, maintains the component's appearance through repeated use in harsh conditions, and provides hard-wearing protection against scratches and scuffs. For UK RC enthusiasts who run in varied weather and terrain, the anodised finish is a substantial practical advantage.
- Can I use this case with a different motor or ESC? — Yes, the motor mount and gearbox case is designed to accommodate the standard motors and electronic speed controllers fitted to Arrma 4S vehicles. As long as you're using components compatible with your specific Arrma 4S model, this aluminium case will work without issues. If you've upgraded to a significantly larger or smaller motor, verify compatibility before installation.
- What is the weight difference between this aluminium case and the stock plastic version? — The aluminium case is slightly heavier than plastic, but the weight difference is negligible (typically a few grams) and does not negatively impact performance. The structural benefits and heat dissipation advantages far outweigh any minor weight increase.
- Is this case waterproof or water-resistant? — The case itself provides a sealed housing for your motor and gearbox, but the level of water resistance depends on the condition of seals and gaskets. For normal outdoor RC bashing in wet conditions, the sealed aluminium construction provides reliable protection. For submersion in water or extended wet conditions, inspect seals regularly and ensure all fasteners are secure.
