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

Rear axle shafts in hardened #45 spring steel

This 4 pcs axle shaft set is designed as a direct swap for TRX4 Trail Crawler rear shafts, transmitting motor output into gear and wheel rotation. Each shaft is made from hardened #45 steel with a spring steel tempering process to boost surface strength and resistance to wear, while preserving original fitment dimensions.

Shaft lengths follow factory specifications: long shafts measure 68.5mm and short shafts 59.5mm. The set of four covers both sides and retains the stock mounting points so installation is straightforward in the factory axle housing.

For routine maintenance or when stock parts show wear, these shafts offer increased longevity under crawling and low-speed torque without changing gear ratios or axle alignment.

A no-frills axle shaft replacement offering improved wear resistance while keeping stock behaviour for the TRX4 Trail Crawler.
