TRAXXAS TRX4 rear axle shafts upgrade TRX45968 by GPM  [TRX45968]

Heavy-duty rear axle shafts for TRX4 Trail Crawler

This 4 pcs axle shaft set fits as a straight swap for the TRX4 Trail Crawler rear axle shafts and carries the torque from the motor into the geartrain and wheels. Each shaft is produced from hardened #45 steel and receives a spring steel hardening treatment to increase surface hardness and wear resistance without altering stock fitment.

The set matches factory lengths: long shafts at 68.5mm and short shafts at 59.5mm, supplied as four pieces to replace both sides. Mounting geometry and interface points are intended to be identical to the original shafts so they install into the stock axle housing and work with the factory assembly.

These shafts are suitable as a maintenance replacement when originals show wear, aiming to extend service under sliding and slow-speed crawling conditions while maintaining the original drivetrain behaviour.

A reliable stock-fit replacement that focuses on improved wear resistance for TRX4 rear drivetrains.
