TRAXXAS TRX4 CVD Main Shafts 14pcs Adjustable Front Rear TRX4037SA by GPM  [TRX4037SA]

Precision fit adjustable CVD shafts for TRX4 drivetrains

This 14pcs CVD main shaft set is an aftermarket driveline upgrade intended for TRAXXAS TRX4 Trail Crawler platforms, engineered for balanced mass distribution using aluminum 6061 T6 with steel reinforcements at wear points. The assembly transfers torque from the motor into the driveline while providing adjustable sections to tune chassis and axle spacing for scale crawling setups.

The telescoping configuration covers front adjustment from 102-112mm and rear adjustment from 122-132mm to accommodate common link lengths. Aluminum components carry an anodized finish for oxidation resistance and consistent appearance. Modular joint and body components permit targeted servicing and part replacement without full assembly exchange.

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. This set is intended for hobbyist TRX4 scale crawler use and for users adjusting driveline geometry and axle spacing rather than for real vehicle applications.

For accurate driveline geometry tuning on TRX4 crawlers, this set offers adjustable lengths and modular serviceability; retain spare seals and fasteners for aftermarket rebuilds.
