Key Features
- Premium Aluminium Construction — Manufactured from high-quality aluminium rather than plastic, this differential housing offers significantly improved strength and durability, ensuring your RC monster truck can handle aggressive driving and high-impact collisions without cracking or deforming.
- Enhanced Heat Dissipation — The aluminium material naturally disperses heat generated during driving more effectively than plastic alternatives, keeping your differential running cooler during extended bash sessions and maintaining optimal performance throughout the day.
- Professional Red Anodised Finish — The vibrant red anodised coating not only looks fantastic on your RC car but also provides a protective layer against corrosion and wear, extending the component's lifespan and maintaining its appearance through countless hours of use.
- Universal Compatibility — Designed to fit the Arrma 1/18 Grom, Granite, and Mojave models, this single component upgrade can be installed on multiple vehicles in your RC collection, offering exceptional value for enthusiasts with several Arrma trucks.
- Direct Bolt-On Installation — This upgrade requires no modification to your existing RC monster truck, allowing for straightforward installation using standard tools and RC hobby knowledge.
- Performance Upgrade Path — Part of Fastrax's comprehensive range of tuning and upgrade options for Arrma vehicles, this differential housing pairs perfectly with other performance modifications to create a fully upgraded RC machine.
Technical Performance
The Fastrax Arrma Grom/Granite/Mojave Aluminium Diff Housing represents a significant mechanical upgrade over standard plastic differential housings found on stock ready to run RC vehicles. Constructed from precision-engineered aluminium, this component provides superior rigidity and strength whilst maintaining the exact same fitment as the original plastic housing. The material choice is deliberate: aluminium offers approximately three times the strength-to-weight ratio of ABS plastic, meaning your differential can absorb impacts and high-torque loads without permanent deformation. The anodised red finish isn't merely cosmetic—it's a hard-coat anodise process that creates a microscopically porous surface that resists scratches, impacts, and corrosion far better than painted or bare aluminium. For UK RC enthusiasts who take their hobby seriously, whether competing in local racing events or simply pushing their vehicles hard on backyard tracks and natural terrain, this housing upgrade is an economical way to significantly improve durability. The differential housing is the component responsible for distributing torque from your motor to both wheels whilst allowing them to rotate at different speeds during cornering—a critical function that requires absolute reliability. By upgrading to aluminium, you're ensuring this vital component can handle the stresses of high-speed bashing, aggressive cornering, and rough terrain without failure.

- Will this improve my RC monster truck's speed? — Whilst this component doesn't directly increase speed, it enables your vehicle to deliver power more efficiently to the wheels. The improved durability means you can push harder without fear of differential failure, and better heat management helps maintain consistent performance during extended driving sessions.
- Can I use this on multiple Arrma models? — Yes, this housing is compatible with three Arrma 1/18 models: the Grom, Granite, and Mojave. This makes it an excellent upgrade option if you own multiple Arrma trucks.
