TRAXXAS TRX4 Trail Crawler Aluminum & Steel Front/Rear CVD Main Shafts by GPM TRX4037SA  [TRX4037SA]

Aluminum & Steel CVD main shafts for TRX4

This 14pcs CVD main shaft set is an RC-scale driveline upgrade intended for TRAXXAS TRX4 Trail Crawler platforms, combining aluminum 6061 T6 and steel to balance weight and strength for scale trail crawling. The set transfers torque from the motor to the drivetrain while allowing chassis length fine-tuning through adjustable shaft sections.

The shafts use an adjustable design to accommodate different suspension lengths, with a front usable range of 102-112mm and a rear range of 122-132mm. Anodized finishes are applied to the aluminum components for corrosion resistance and a consistent appearance. The joints and main-body components are modular so rebuild kits are possible and parts can be serviced separately.

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 axle length and driveline geometry rather than for real vehicle applications.

Use these shafts to refine axle spacing and driveline durability on TRX4 scale crawlers, and keep spare joints if you plan to rebuild or re-serve the assemblies after heavy use.
