TRAXXAS TRX4 Trail Crawler Steel #45 Front CVD Joints by GPM TRX44571/JT  [TRX44571/JT]

Front CVD joint for TRX4

This 2 pcs front CVD joint set is an RC-scale drivetrain replacement part made for TRAXXAS TRX4 Trail Crawler platforms, supplied by GPM as model TRX44571/JT. The joints transmit torque from the motor through the gearbox and drive shafts to the front wheels, providing the mechanical link between internal gearing and wheel hubs.

Manufactured from hardened steel #45 with a heat treatment process, these CVD joints are intended to match original equipment fit and form. The design emphasizes durability for low-speed crawling tasks where constant torque transfer and part endurance are primary concerns.

Installation notes: these parts replace the front CVDs and typically install using the existing axle and hub hardware on TRX4 platforms. Check spline engagement and retaining hardware torque during assembly, and verify free movement of suspension components after installation to avoid binding.

Tuning and maintenance: hardened steel joints increase wear resistance but still require periodic inspection for play or fatigue when used in heavy or frequent crawling sessions. Keep mating splines clean, apply appropriate grease to sliding interfaces where applicable, and replace if excessive wear or distortion appears.
