TRX4 Compatible Rear Axle Shafts Spring Steel TRX45968/SH by GPM  [TRX45968/SH]

Axle shafts for TRX4 rear end

This two-piece rear axle shaft kit is supplied as a direct replacement for TRAXXAS TRX4 TRAIL CRAWLER rear driveline parts on scale RC rigs. The shafts transmit motor rotation into the gearbox and gearset to enable controlled low-speed crawling and consistent torque transfer on rough trails.

Produced from hardened #45 spring steel with a nutrient hardening process, these shafts are made to match original dimensions while enhancing surface durability for trail use. The set includes two shafts for the long and short rear positions.

Reference lengths from the product source are 68.5mm for the longer shaft and 59.5mm for the shorter shaft; use these numbers to confirm compatibility with your existing axle components before installing.

Fitment and maintenance notes: these shafts are fitted inside the axle housing and work with your existing dogbones, gears, and bearings; check bearing condition and mating surfaces when replacing shafts and ensure fasteners are torqued to the correct spec for safe operation.
