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

Hardened #45 rear axle joint for TRX4

This is an aftermarket rear axle joint produced for the TRAXXAS TRX4 Trail Crawler, supplied as a 2pcs set and identified by GPM TRX45968/JT. It is an RC-scale replacement part intended to carry rotational force from the motor into the drivetrain while maintaining alignment with the axle gears.

The component is made from Harden steel #45 and has undergone a nutrified and hardening process to increase wear resistance compared with untreated steel. The geometry and fit match the original part, so it is intended to replace worn or damaged rear axle joints without requiring modifications to the chassis.

Installation notes: check mating surfaces and existing bearings for wear before fitting, verify smooth rotation after assembly, and inspect for proper clearance during suspension travel. As a drivetrain part, this joint affects power transfer and drivetrain feel, so it can be considered when tuning for smoother gear engagement or longevity.
