Technical Performance

The Traxxas 27-T Pinion Gear exemplifies the engineering excellence that goes into RC drivetrain components. At 0.8 metric pitch, this pinion gear is designed to mesh perfectly with Traxxas UDR spur gears in the 32-pitch standard used across modern pro-scale short course trucks. The 27-tooth configuration strikes an optimal balance for desert racing applications, providing sufficient low-end torque for sandy and loose terrain whilst maintaining adequate top-end capability when running on faster tracks. The 5mm bore ensures a secure fit on compatible Traxxas motor shafts, eliminating slippage during hard acceleration and maintaining consistent power delivery whether you're navigating tight technical sections or powering through open desert. Traxxas manufacturing processes ensure that each tooth is precisely formed, preventing gear mesh issues that can lead to noise, vibration and premature wear. The pinion gear's robust construction means it withstands the stresses of competitive RC racing, including hard cornering, high-speed landings and aggressive throttle inputs. For UK RC enthusiasts operating Traxxas UDR Unlimited Desert Racer models with Fox Racing suspension or Rigid Industries variants, this pinion gear represents the authentic, proven solution for maintaining optimal drivetrain performance.

Frequently Asked Questions

• Is the Traxxas 27-T Pinion Gear compatible with my Traxxas UDR? — Yes, this pinion gear is specifically designed for Traxxas UDR Unlimited Desert Racer models. It is compatible with both the Pro-Scale 4WD RTR Short Course Truck with Rigid Industries suspension (TRX85086-4-RGD1) and the Fox Racing variant (TRX85086-4-FOX1). The 5mm shaft bore and 27-tooth, 0.8 metric pitch specification match Traxxas UDR motor and drivetrain components perfectly.
• What is the difference between metric pitch and imperial pitch pinion gears? — This pinion gear uses 0.8 metric pitch, which is the metric standard for gear specifications. It is compatible with 32-pitch spur gears, which is the standard pitch used in modern Traxxas short course truck designs. Using the correct pitch specification ensures proper meshing and prevents drivetrain issues that can arise from mixing incompatible gear standards.
• How often do I need to replace my pinion gear? — Pinion gear replacement frequency depends on your usage intensity. For competitive racers, replacement every 5-10 hours of running time is common. For casual bashers, pinion gears typically last much longer. Signs of wear include visible tooth damage, striping or unusual grinding noises from the drivetrain. Regular inspection after intensive sessions ensures early detection of wear.
• Will this pinion gear work with aftermarket motors? — This pinion gear is designed for motors with a 5mm shaft bore, which is the Traxxas standard. Many aftermarket motors feature compatible 5mm shafts, but you should verify your specific motor's shaft specification before purchasing to ensure compatibility.
• What tools do I need to install this pinion gear? — Installation requires a motor tool or hex driver set to secure the pinion gear onto your motor shaft. Some users prefer using threadlock compound on the set screw for added security during high-intensity driving. A basic RC toolkit with these items is all that's needed for straightforward installation.
• Is this part suitable for beginners? — Yes, installing a pinion gear is one of the more straightforward drivetrain maintenance tasks. Beginners can easily replace a worn pinion gear with basic tools. However, understanding gear ratios and mesh specifications becomes more important if you're tuning your vehicle's performance, which is where experienced RC knowledge becomes valuable.
