TRX4 Aftermarket Rear Axle Shafts Set TRX45968/SH by GPM  [TRX45968/SH]

Rear axle replacement shafts for TRX4

This 2-piece rear axle shaft set is supplied as a direct replacement for TRAXXAS TRX4 TRAIL CRAWLER rear driveline components fitted to scale RC models. The shafts transmit motor rotation into the gearbox and gear train to support controlled, low-speed crawling and reliable torque delivery.

Forged from hardened #45 spring steel with a nutrient hardening process, the shafts mirror original geometry while improving wear resistance for off-road crawling duty. The set contains two shafts made for the short and long rear axle positions.

Measured lengths from the source: longer shaft 68.5mm and shorter shaft 59.5mm, which you should compare against your current axle parts to confirm fitment before installation.

Practical fit and maintenance advice: the shafts sit inside the axle housing and interface with your existing dogbones, gears, and bearings; inspect mating surfaces and bearings for wear before swapping and retorque fasteners to the recommended settings to ensure dependable service.
