TRAXXAS TRX4 Front CVD Hardened Steel Upgrade - TRX44571 by GPM  [TRX44571]

Front CVD unit compatible with TRX4

This front CVD (constant velocity drive) is a scale RC drivetrain part designed to deliver torque from the motor and gearbox to the front wheels on a TRAXXAS TRX4 Trail Crawler chassis. Manufacturing uses hardened steel #45 combined with nutrifying and heat-treatment to improve surface hardness and extend component life under crawling loads.

Under real-world crawling the CVD smooths rotational transfer and keeps torque flow steady during slow, technical moves. Supplied as a pair for front axle fitment, the parts match factory geometry and are intended for direct replacement where TRX4 front CVDs are specified.

Installation guidance: replace on a like-for-like basis, confirm spline seating and axle retention torque, avoid over-tightening fasteners that preload the joint, and check for interference with suspension travel. Proper differential tuning and wheel offset choice will also help protect drivetrain components.

A direct replacement front CVD set for TRX4 owners seeking a hardened steel option to increase wear resistance in scale crawling use.
