GPM TRX4 Trail Crawler Front CVD Joints Hardened Steel #45 TRX44571/JT - RC Spare Part  [TRX44571/JT]

Front CVD unit compatible with TRX4 driveline

This 2 pcs front CVD joint set is an RC-scale drivetrain replacement part compatible with TRAXXAS TRX4 Trail Crawler platforms, designated TRX44571/JT. The joints transfer torque from the motor through the gearbox and drive shafts to the front wheels, forming the mechanical link between internal gearing and the wheel hubs.

Manufactured from hardened steel #45 with controlled heat treatment, these CVD joints are made to match original fit and form. The geometry focuses on durability for low-speed crawling where steady torque transfer and long life are essential.

Installation notes: these parts replace the front CVDs and normally install using the stock axle and hub hardware on TRX4 vehicles. Verify spline engagement and the torque on retaining screws during assembly, and confirm free suspension movement after fitting to prevent binding.

Tuning and maintenance: hardened steel improves wear resistance but still needs routine checks for play or fatigue after heavy use. Keep mating splines free of grit, apply light grease to sliding interfaces where applicable, and replace components showing significant wear or deformation.
