GPM TRAXXAS TRX4 Front CVD Hardened Steel #45 - TRX44571 - RC Spare Part  [TRX44571]

TRX4 front constant velocity drive upgrade

This front CVD (constant velocity drive) is an RC drivetrain component engineered to carry torque from the gearbox to the front wheels on a TRAXXAS TRX4 Trail Crawler chassis. The component is made from hardened steel #45 with a nutrified and heat-treated finish to boost wear resistance and service life under crawling loads.

In use the CVD keeps geartrain motion smooth while providing steady power delivery during the low-speed, high-torque moves common in scale crawling. The part ships as a 2 pcs set for front axle installation and follows original geometry for direct replacement where a TRX4 front CVD is required.

Installation tips: swap like-for-like, confirm spline engagement and axle retention hardware torque, avoid over-tightening fasteners that preload the joint, and check clearance against suspension components. For setup, the hardened material adds durability but pairing with suitable differential settings and wheel offset will help extend drivetrain life.

This CVD set offers a direct-fit front drivetrain replacement for TRX4 maintenance, supplying a hardened steel alternative to improve wear resistance during scale crawling duty.
