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

#45 hardened rear axle joint tailored for TRX4 use

This aftermarket rear axle joint fits TRAXXAS TRX4 Trail Crawler kits and is supplied as a 2pcs set, model TRX45968/JT. It serves as a scale replacement part to transmit motor output into the rear drivetrain while keeping axle gear alignment intact.

Made from Harden steel #45, the component has been through a nutrified and hardening process to boost wear resistance versus untreated steel. Its dimensions mirror the original part so it replaces worn or broken joints without the need for chassis modification.

Fitment tips: check bearing seats and mating surfaces before installation, ensure smooth rotation after fitting, and verify there is no interference during suspension articulation. Because this joint affects driveline behaviour, it is suitable for hobbyists looking to improve durability and consistency in power transfer.
