TRX4 Front CVD Joints Pair Hardened Steel #45 TRX44571/JT by GPM  [TRX44571/JT]

Front CVD assembly for TRX4 use

This two-piece front CVD joint set is an aftermarket drivetrain component compatible with TRAXXAS TRX4 Trail Crawler platforms, identified as TRX44571/JT. The units pass torque from the gearbox and drive shafts into the front hubs, acting as the link between internal gears and wheel centres.

Produced from heat-treated hardened steel #45, these CVDs aim to mirror original dimensions while offering enhanced resistance to wear. The focus is on steady performance during low-speed crawling where component endurance matters most.

Installation tips: these replace the front CVDs and generally fit with the existing axle and hub hardware on TRX4 models. Check spline seating and fastener torque during installation, and ensure suspension travel remains free throughout the range of movement.

Maintenance advice: hardened steel improves longevity but check periodically for play or fatigue in demanding use. Keep splines clean, apply a light grease to sliding parts if needed, and swap them out when excessive wear appears.
