Technical Performance
The Fastrax Arrma Grom/Granite Aluminium Rear Gearbox Cover represents a significant upgrade in build quality and engineering compared to factory plastic covers. The aluminium material selection is crucial here — aluminium offers superior strength-to-weight ratio, meaning you get robust protection without adding excessive bulk to your RC vehicle. The material's thermal properties are particularly beneficial in the gearbox area, where friction and motor heat can accumulate, especially during high-speed runs or extended bashing sessions. By upgrading to this aluminium cover, you're protecting one of the most critical drivetrain components on your Arrma 1/18 Granite Grom Mega 380 Brushed 4x4 Monster Truck. The gearbox assembly contains precision gears, bearings, and differential components that are essential to your vehicle's performance, and this protective cover helps shield them from dirt, moisture, and impact damage. The engineering behind this part demonstrates Fastrax's commitment to creating components that enhance durability without compromising the fit and function of the original design. Whether you're running your RC car on rough terrain, navigating technical courses, or simply enjoying casual basher sessions, this upgrade provides peace of mind knowing your gearbox is protected by professional-grade aluminium construction.
