TRX4 Rear Axle Joint Harden Steel #45 TRX45968/JT by GPM  [TRX45968/JT]

Harden steel #45 rear joint for TRX4 drivetrains

This aftermarket rear axle joint is made for TRAXXAS TRX4 Trail Crawler applications and is supplied as a 2pcs set, model TRX45968/JT. It is a scale replacement designed to pass motor torque into the drivetrain while keeping the axle gears aligned.

The part is manufactured from Harden steel #45 and has gone through a nutrified and hardening process to improve wear resistance compared with untreated steel. The geometry and fit are matched to the original item so it installs as a direct replacement for worn or damaged rear axle joints without requiring chassis modification.

Installation notes: inspect mating surfaces and bearings for wear before fitting, confirm smooth rotation after assembly, and check clearance through full suspension travel. As a drivetrain component, this joint influences power transfer and the overall drive feel, so consider it when tuning for quieter gear engagement or extended service life.
