TRAXXAS TRX4 Front and Rear CVD Shafts Adjustable Set TRX4037SA by GPM  [TRX4037SA]

Front and rear adjustable CVD main shafts

This 14-piece CVD main shaft kit is an aftermarket driveline upgrade for TRAXXAS TRX4 Trail Crawler platforms, pairing aluminum 6061 T6 with steel to balance lightness and localized strength for scale crawling. The assembly transmits torque to the drivetrain while allowing axle spacing adjustments through its adjustable sections.

Designed for a variety of link and suspension setups, the front shafts adjust from 102-112mm and the rear from 122-132mm. Anodized aluminium parts resist surface wear and keep a consistent finish, while the modular construction supports servicing and part replacement without swapping the entire unit.

Included small hardware supports installation and rebuilds: 2.5xM4x11 stainless steel screw shaft - 4pcs, 4x2.5 white silicone O-ring - 4pcs, 4x1 white silicone O-ring - 4pcs. The set is intended for hobby use on TRX4 scale crawlers and for users tuning driveline geometry rather than for vehicle-level use.

Fit these shafts to tune axle spacing and improve driveline resilience on TRX4 crawlers, and plan to replace O-rings during regular maintenance.
