AXIAL WRAITH Tunable Main Shaft for Off-Road WR037SA by GPM  [WR037SA]

Alloy Main Shaft for AXIAL WRAITH

This main shaft set is an aftermarket upgrade for AXIAL WRAITH axles, offering adjustable length to refine drivetrain geometry. The assembly pairs a 6061-T6 aluminum shaft body with hardened #45 steel universal swing shafts using a cross head layout to preserve pivot alignment through steering movement.

The alloy shaft body reduces rotating mass compared with full-steel options, while the hardened swing shafts protect key wear surfaces at the cross head and pivot mounts. The adjustable span supports wheelbase settings from 126mm to 135mm so you can tune steering response and climb angle for trail conditions.

Original small parts are supplied to aid assembly and sealing, including white silicone O-rings and mounting screws to lock the shaft into standard WRAITH housings. Installation is aimed at hobbyists comfortable with axle teardown; always check for binding across full suspension travel and steering range before use.

Use this kit when you need a lighter alloy main shaft with hardened swing elements to adjust wheelbase and improve articulated steering for scale rock crawling on AXIAL WRAITH rigs.
