TRAXXAS TRX4 Trail Crawler Steel #45 Front CVD by GPM TRX44571  [TRX44571]

Front CVD for TRX4 Trail Crawler

This front CVD (constant velocity drive) is an RC-scale drivetrain component designed to transfer torque from the motor and gearbox to the front wheels on a TRAXXAS TRX4 Trail Crawler chassis. The part is manufactured from hardened steel #45 with a nutrifying and hardening process to increase wear resistance and service life under crawling loads.

In practical use the CVD leads the gears to spin smoothly while maintaining consistent power delivery during low-speed, high-torque maneuvers typical in scale crawling. The part is supplied as a 2pcs set intended for front axle fitment, and matches original geometry for direct replacement where the TRX4 front CVD is required.

Installation notes: replace like-for-like, check mating spline engagement and axle retention hardware, avoid over-tightening fasteners that preload the joint, and inspect for proper clearance with suspension components. For tuning, the hardened material improves durability but pairing with appropriate differential setup and wheel offsets will help preserve drivetrain longevity.

This CVD set provides a direct replacement option for TRX4 front drivetrain maintenance, offering a hardened steel alternative for increased wear resistance during scale crawling operations.
