TRAXXAS TRX4 rear axle replacement shafts TRX45968 by GPM  [TRX45968]

Durable spring steel rear axle shafts for Trail Crawler

This 4 pcs axle shaft kit is a direct replacement for the TRX4 Trail Crawler rear axle shafts, responsible for transferring motor torque into gear and wheel movement. The components are made from hardened #45 steel with a spring steel hardening treatment that increases surface hardness and wear resistance while keeping factory fitment unchanged.

Measured to factory lengths, the long shafts are 68.5mm and the short shafts are 59.5mm, supplied as a 4 pcs set to cover both sides of the rear axle. Geometry and mounting features are retained so these shafts fit the stock axle housing and axle assembly.

Fit these shafts as part of preventative maintenance or when originals show wear; they are aimed at improving durability during sliding contact and low-speed crawling without altering drivetrain alignment.

A practical replacement set focused on restoring drivetrain durability while maintaining factory behaviour on TRX4 Trail Crawler builds.
