Key Features
- Tough Composite Material Construction — The diff case is manufactured from durable composite material that delivers consistent performance even under extreme operating conditions, ensuring your RC car UK model can handle aggressive driving, high-speed runs, and challenging terrain without premature wear or failure.
- Precision Manufactured Gear Tooth Configuration — Each gear features meticulously engineered tooth profiles that mesh smoothly and reliably, eliminating noise, vibration, and gear slippage that would otherwise compromise acceleration, handling, and overall driving experience in your RC vehicle.
- High-Quality Diff Case Molding — The superior moulding process creates a reliable diff seal that prevents lubricant leakage and contamination, maintaining optimal gear lubrication and extending component lifespan during extended driving sessions in dusty or wet conditions.
- Integrated Ring Gear and Diff Case Design — By combining the ring gear and differential case into a single unified component, ARRMA achieves exceptional structural strength and integrity, reducing the risk of misalignment or component separation that can occur with traditional multi-piece designs.
- OEM Replacement Quality — This is a genuine ARRMA component designed to meet the exact specifications of the original equipment, ensuring perfect fit, function, and compatibility with your model's existing transmission and drivetrain components.
Technical Performance
The ARRMA Diff Case 49T Main Gear 17T Input Gear Set represents the manufacturer's commitment to precision engineering and reliability in RC car UK drivetrain systems. The 49-tooth main gear and 17-tooth input gear combination is specifically engineered for ARRMA models including the 1/10 GRANITE 4x4 RTR Brushed Monster Truck, the 1/10 SENTON 4x4 RTR Brushed Short Course Truck, and the 1/8 TYPHON 4x4 RTR Brushed Buggy. The composite material construction offers an excellent balance between durability and weight, allowing these gears to handle the torque and stress generated by brushless motors whilst maintaining responsiveness and acceleration performance. The precision tooth configuration minimises backlash and gear noise, delivering smooth power delivery and predictable handling characteristics whether you're driving a monster truck, short course truck, or buggy variant. The integrated ring gear and diff case design eliminates potential weak points in the drivetrain, creating a robust assembly capable of sustained high-performance operation. Quality moulding ensures that the differential seal remains effective throughout the component's service life, protecting internal mechanisms from dirt, dust, and moisture contamination that would otherwise degrade performance and require premature replacement.

Replacing worn gears restores smooth operation, eliminates noise and vibration, improves acceleration response, and prevents further drivetrain damage that could affect other transmission components. Many RC enthusiasts also keep spare diff assemblies on hand for quick repairs when racing or bashing.
- Is this a genuine ARRMA component? — Yes, this is an official ARRMA part (model number AR310802) manufactured to exacting OEM standards. Purchasing genuine replacement parts ensures perfect compatibility, reliability, and performance compared to aftermarket alternatives.
- What materials are used in this diff case assembly? — The diff case and associated components are manufactured from tough composite material specifically formulated for RC applications, providing the ideal balance of strength, durability, and weight for reliable long-term performance under demanding driving conditions.
- How difficult is it to install this diff case and gear set? — Installation difficulty depends on your mechanical experience and familiarity with your specific ARRMA model's transmission assembly. The components are precision-engineered for straightforward installation, though we recommend consulting your model's assembly manual or contacting our experienced RC enthusiasts for guidance if this is your first time performing drivetrain maintenance.
- Can I use this as an upgrade rather than just a replacement? — Whilst this is primarily designed as a replacement for original kit-supplied components, many RC enthusiasts use genuine OEM parts as upgrades to restore performance to like-new condition or to have spare assemblies available for competition or intensive bashing sessions.
