TRAXXAS TRX4 Aftermarket Adjustable Main Shaft TRX4037SAN by GPM  [TRX4037SAN]

Steel adjustable axle shaft for TRX4 rigs

The TRX4037SAN set is an aftermarket replacement for the TRAXXAS TRX4 Trail Crawler, supplying a steel adjustable main shaft housed in an alloy body along with the supplied silicone o-rings and screw shafts. A universal swing-shaft cross head increases steering and crawl angles on scale runs, while a pinned head design helps prevent components from coming loose during articulation.

Measured shaft lengths include separate front and rear adjustable ranges so you can tune wheelbase and axle offset to suit clearance needs and vehicle balance. White silicone o-rings act as protective cushions to reduce metal-on-metal contact and limit wear at extreme articulation angles.

Fit this kit to refine axle placement and steering geometry on TRX4 crawlers, prioritising robust fit and better ground clearance for technical trails.
