TRX4 Rear Spring Steel Axle Shaft Set TRX45968/SH by GPM  [TRX45968/SH]

Rear shaft set for TRX4 driveline

This 2 pcs rear axle shaft set is a direct aftermarket replacement for TRAXXAS TRX4 TRAIL CRAWLER rear driveline components used on scale RC models. The shafts route motor torque into the gearbox and geartrain to enable low-speed crawling and smoother torque delivery on technical trail sections.

Manufactured from hardened #45 spring steel with a nutrient hardening process, the shafts retain original geometry while offering improved wear resistance for dedicated crawling use. The kit contains two shafts made to fit the long and short rear axle positions.

Length data from the source: the longer shaft measures 68.5mm and the shorter shaft measures 59.5mm, which you can check against your vehicle's existing axle pieces before fitting.

Installation and setup tips: these shafts install inside the axle housings and mate with your existing dogbones, gears, and bearings; inspect mating surfaces and bearings for wear before swapping parts and retorque any fasteners to the vehicle manufacturer's specs for reliable operation.
