TRX4 Trail Crawler Front CVDs Hardened Steel #45 TRX44571/JT by GPM  [TRX44571/JT]

Front CVDs for TRX4 driveline upgrades

This 2 pcs front CVD joint set is an aftermarket replacement compatible with TRAXXAS TRX4 Trail Crawler platforms and listed as TRX44571/JT. The joints deliver torque from the gearbox and drive shafts to the front wheels, providing the connection between gear outputs and wheel hubs.

Constructed from hardened steel #45 with heat treatment, these CVDs are sized for OE-style fit while prioritising toughness for low-speed crawls. The design is focused on resisting wear under constant torque loads common in scale crawling.

Fitment guidance: the parts swap in for the front CVD assemblies and normally use the original axle and hub hardware on TRX4 rigs. Confirm spline engagement and retention torque when assembling, and check suspension articulation to ensure no binding occurs.

Care and tuning: hardened steel improves durability but still needs regular inspection during heavy use. Keep splines clean, use a light lubricant on moving faces, and replace parts showing excessive wear or distortion.
