TRX4 Trail Crawler Rear Axle Shaft Set TRX45968/SH by GPM  [TRX45968/SH]

Replacement rear axle shafts for TRX4

This set of 2 rear axle shafts is designed as a direct replacement for TRAXXAS TRX4 TRAIL CRAWLER rear driveline components on scale RC vehicles. The shafts convert motor torque through the gearbox and gear train to support precise, low-speed crawling on trail obstacles.

Made from hardened #45 spring steel with a nutrient hardening process, the shafts keep the original geometry while delivering enhanced wear resistance for demanding scale crawling. The pair includes one long and one short shaft for the rear assembly.

Length specifications provided by the source: long shaft 68.5mm and short shaft 59.5mm; these measurements help confirm fitment against your current axle parts before you install them.

Installation advice: shafts are fitted inside the axle housing and interface with existing dogbones, gears, and bearings; inspect mating parts and bearings for wear prior to replacement and tighten fasteners to the vehicle maker's torque recommendations for safe, reliable operation.
