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

Front CVD assembly for TRX4 crawlers

This front constant velocity drive is an RC-scale drivetrain element designed to move torque from the motor and gearbox to the front wheels on a TRAXXAS TRX4 Trail Crawler chassis. Components are produced in hardened steel #45 with a nutrified and heat-treated process to raise surface hardness and service life under crawling stresses.

During crawling the CVD promotes smooth gear engagement while keeping torque delivery consistent through slow, technical maneuvers. Supplied as a two-piece front set, the components retain original geometry for direct replacement where TRX4 front CVDs are called for.

Fitment advice: replace like-for-like, verify spline alignment and axle retention hardware, avoid excessive fastener torque that preload the joint, and ensure adequate clearance with suspension parts. When tuning, using appropriate differential setup and wheel offsets will reduce drivetrain strain.

A direct-replacement front CVD set for TRX4 owners seeking a hardened-steel option to increase wear life during scale crawling sessions.
