Technical Performance
The Traxxas Sun planetary (Rear) TRX8587 represents the precision engineering that Traxxas has perfected over decades of RC vehicle development. As a planetary sun gear, this component sits at the heart of the differential system, working in concert with planetary pinion gears and ring gears to manage torque distribution between the left and right wheels during cornering, acceleration and deceleration. The rear placement indicates this gear is specifically configured for rear-axle differential operation, making it essential for vehicles like the Traxxas UDR Unlimited Desert Racer, which demands exceptional drivetrain reliability during high-speed desert running and technical rock crawling. The precision machining and material selection ensure that the TRX8587 maintains consistent mesh with surrounding gears, reducing vibration, noise and energy loss. Built to the same exacting standards as all Traxxas drivetrain components, this sun gear will deliver the performance characteristics and longevity expected from a manufacturer that has set the standard for RC vehicle quality and innovation throughout the UK and globally.

Frequently Asked Questions
- What models is the Traxxas TRX8587 sun gear compatible with? — The TRX8587 is specifically designed for the Traxxas UDR Unlimited Desert Racer Pro-Scale 4WD RTR Short Course Truck, compatible with both the Rigid Industries version (TRX85086-4-RGD1) and the Fox Racing version (TRX85086-4-FOX1). If you own either of these models and need a replacement rear planetary sun gear, the TRX8587 is the correct part for your vehicle.
- Why would I need to replace the planetary sun gear on my RC short course truck? — The rear planetary sun gear is a critical drivetrain component that experiences significant stress during aggressive driving, high-speed acceleration and challenging terrain navigation. Over time and with heavy use, this gear can experience wear, damage or stripping that compromises differential function and vehicle handling. Replacing it with a genuine Traxxas TRX8587 restores your vehicle's performance and ensures reliable torque distribution to both rear wheels.
- Is this a genuine Traxxas part? — Yes, the TRX8587 is a genuine original equipment manufacturer part produced by Traxxas. When you order this part from RC Model Shop, you're receiving an authentic Traxxas component backed by the manufacturer's reputation for quality and performance.
- Do I need any special tools to install the TRX8587? — Installation of the planetary sun gear typically requires basic RC vehicle maintenance skills and standard hobby tools. Most owners comfortable with RC vehicle maintenance can complete the installation themselves, though specific procedures should be followed according to your vehicle's service manual to ensure correct assembly and mesh with other differential components.
- What is the difference between a sun gear and other planetary gears? — In a planetary differential system, the sun gear is the central gear that meshes with the smaller planetary pinion gears, which in turn mesh with the outer ring gear. The sun gear's position and specifications determine how torque is distributed through the differential, making it essential for proper vehicle handling and traction management during cornering and acceleration.
