Overview
The Traxxas Ring Differential / Pinion Gear Differential TRX5379X is an essential replacement drivetrain component for RC enthusiasts who demand genuine quality and reliable performance. Whether you're a seasoned RC car UK hobbyist or someone looking to maintain your brushless RC truck, this front differential gear set ensures your vehicle continues to perform at its best. Traxxas is renowned for engineering precision-crafted spare parts that maintain the integrity of your RC model, and this differential assembly is no exception.
This differential features a 37-tooth ring gear paired with a 13-tooth pinion gear, specifically engineered for front differential applications across a wide range of Traxxas vehicles. These gears are essential components that distribute power from your motor to the front wheels whilst allowing them to rotate at different speeds during cornering. For anyone serious about maintaining their RC 4WD truck, buggy, or short course truck, having genuine Traxxas replacement gears on hand is crucial for uninterrupted outdoor bashing and racing.
RC Model Shop stocks this genuine Traxxas component as part of our comprehensive range of RC car spares and tune-up parts. Whether your differential has suffered wear from aggressive driving, competition use, or simply needs refreshing after months of weekend bashing, this replacement set will restore your vehicle to factory specifications and performance standards.
Key Features
- 37-tooth Ring Gear — The ring gear is the larger component of this differential set, receiving rotational force from the pinion and distributing it to both front wheels, ensuring smooth power delivery during acceleration and cornering.
- 13-tooth Pinion Gear — The pinion gear meshes directly with the ring gear to transfer power from the motor's output shaft, and the 37:13 ratio is precisely engineered to deliver optimal performance across Traxxas's range of 4WD vehicles.
- Front Differential Specific Design — These gears are specifically manufactured for front differential applications, ensuring they integrate seamlessly with your vehicle's drivetrain architecture and maintain the correct mesh and spacing.
- Genuine Traxxas Component — Using official Traxxas parts ensures absolute compatibility with your RC 4WD truck, monster truck, short course truck, or other Traxxas model, maintaining warranty coverage and performance guarantees.
- Wear Replacement — Over time, differential gears suffer wear from aggressive driving, jumping, and hard landings; this replacement set restores your drivetrain to like-new condition and prevents cascading damage to other components.
- Competition and Basher Ready — Whether you're preparing for RC racing or weekend outdoor bashing, having quality replacement gears ensures your vehicle is always race-ready without unexpected failures.
Technical Performance
The Traxxas TRX5379X differential gear set represents precision engineering designed to handle the demands of modern RC driving. The 37-tooth ring gear and 13-tooth pinion gear combination creates a specific gear ratio that balances power delivery with control across numerous Traxxas platform vehicles. These gears must withstand considerable torque loads, especially when paired with brushless motors that deliver instant, powerful acceleration. The engineering tolerances are tight to ensure proper mesh, smooth operation, and longevity under both casual driving and competitive racing conditions. Users have reported that proper slipper clutch adjustment is essential for maximising the lifespan of these gears, particularly when performing high-impact manoeuvres such as jumps and aggressive landings. The gears are manufactured to exacting standards that maintain dimensional accuracy, and genuine Traxxas components offer superior material quality compared to aftermarket alternatives. For drivers engaged in serious RC 4WD truck competitions or those who regularly bash their vehicles on challenging terrain, maintaining differential components in optimal condition is essential for consistent performance and preventing secondary damage to the drivetrain.

Frequently Asked Questions
- Which Traxxas vehicles are compatible with the TRX5379X differential gear set? — The TRX5379X is compatible with a wide range of Traxxas models including the Ford Fiesta ST Rally BL-2S Rally Car, Ford Fiesta ST Rally VXL, Ford Raptor R 1:10 Pro Scale 4WD Brushless Replica Truck, Rustler Ultimate VXL 4x4 1:10 Brushless in multiple colours, Slash Ultimate 4x4 VXL 1:10 4WD Brushless Short Course Truck, Slash VXL 1:10 4x4 RTR Short Course Truck in multiple colours, and Stampede 4X4 HD VXL 1:10 4WD RTR Brushless Electric Monster Truck in multiple colour options. Before purchasing, verify your specific model matches the compatible list to ensure proper fitment.
- What is the gear ratio of this differential set? — The TRX5379X features a 37-tooth ring gear and a 13-tooth pinion gear, creating a specific differential ratio engineered for optimal power distribution and handling characteristics across compatible Traxxas 4WD platforms.
- Will these gears improve my RC truck's performance? — Replacement differential gears restore your vehicle to factory performance specifications if your existing gears have worn or damaged. They won't increase performance beyond original capabilities, but they will eliminate the sluggish or inconsistent behaviour that worn gears cause, restoring smooth power delivery and responsive handling.
- How often do I need to replace my differential gears? — Differential lifespan depends on driving style, terrain conditions, and how well you maintain your slipper clutch. Casual drivers may go years between replacements, whilst competitive racers and aggressive bashers may need new gears every few months. If you notice slipping, grinding, or inconsistent power delivery, it's time to replace your differential gears.
- Is proper installation important for these gears? — Yes. Correct mesh alignment, backlash adjustment, and slipper clutch tuning are essential for these gears to function optimally and last as long as possible. Improper installation can cause premature wear or breakage, particularly during jumps and hard landings. Consult your vehicle's manual for detailed installation instructions.
- Can I use these gears on both front and rear differentials? — No. The TRX5379X is specifically designed for front differential applications. Rear differentials use different gear configurations. Using incorrect gears can cause severe drivetrain damage and poor vehicle handling.
