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

45# hardened rear axle joint compatible with TRX4

This is an aftermarket rear axle joint intended for TRAXXAS TRX4 Trail Crawler models and supplied as a 2pcs set, model TRX45968/JT. It functions as an RC-scale replacement to transmit motor torque into the drivetrain while maintaining correct alignment with the axle gears.

The unit is formed from Harden steel #45 and has undergone a nutrified and hardening procedure to increase wear resistance when compared to untreated steel. The part geometry and mounting points follow the original specification so it replaces worn or damaged joints without modification to the chassis.

Assembly recommendations: examine bearing seats and mating parts for wear before installing, confirm free rotation after assembly, and check clearance during full suspension travel. Because this is a drivetrain component, it can change how power is delivered and should be considered when tuning for smoother engagement or improved longevity.
