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

Harden steel #45 rear axle joint made for TRX4

This aftermarket rear axle joint is intended for TRAXXAS TRX4 Trail Crawler models and comes as a 2pcs set, model TRX45968/JT. It is a scale replacement component that transmits motor power into the drivetrain while preserving correct alignment of the axle gears.

The part is produced from Harden steel #45 and has been processed with a nutrified and hardening treatment to raise wear resistance relative to untreated steel. Its shape and fit follow the OEM dimensions so it can replace worn or damaged rear axle joints without chassis modification.

Fitment guidance: check bearing seats and mating surfaces for wear prior to fitting, ensure smooth rotation after assembly, and verify there is adequate clearance during suspension movement. This joint plays a role in overall drivetrain behaviour, so consider its effect when adjusting gearing or tuning for longevity.
