TRAXXAS TRX4 rear axle shaft set TRX45968 by GPM  [TRX45968]

Hardened spring-steel rear axle shafts for TRX4

This 4 pcs axle shaft set is a direct replacement for the TRX4 Trail Crawler rear axle shafts, handling the drivetrain task of converting motor torque into gear rotation and wheel movement. The shafts are manufactured from hardened #45 steel with an added spring steel hardening step to raise surface hardness and improve wear resistance while retaining stock fitment.

Lengths mirror factory parts, with long shafts at 68.5mm and short shafts at 59.5mm, supplied as a 4 pcs set to service both sides. The shaft geometry and mounting points match the original design so they install into the existing axle housing and work with the stock axle assembly without modification.

As a tune-up item these shafts are intended to extend service life under sliding and low-speed crawling loads while keeping drivetrain alignment and behaviour unchanged. Replace worn originals or fit these during maintenance to restore smooth gear engagement and reduce shaft wear.

A straightforward stock-replacement axle set focused on renewed drivetrain durability and direct fitment for TRX4 Trail Crawler rigs.
