TRX4 Precision Rear Axle Shafts TRX45968/SH by GPM  [TRX45968/SH]

Rear axle shafts engineered for TRX4 driveline

This 2-piece rear axle shaft set is engineered as a direct aftermarket replacement for TRAXXAS TRX4 TRAIL CRAWLER rear driveline components used on scale RC models. The shafts are designed to transfer motor torque into the gearbox and gear train to support controlled, low-speed crawling and consistent torque transmission on technical terrain.

Fabricated from hardened #45 spring steel with a nutrient hardening process, these shafts maintain original dimensions while delivering increased surface hardness and wear resistance for sustained crawler duty. The set includes two shafts matched for the long and short rear axle positions.

Dimensional data supplied by the product source: long shaft 68.5mm, short shaft 59.5mm; verify these values against your existing axle pieces to confirm correct fitment prior to installation.

Assembly and service notes: the shafts fit inside standard axle housings and interface with dogbones, gears, and bearings; inspect bearing surfaces and mating parts before replacement and torque fasteners to the recommended settings for dependable operation.
