TRAXXAS XO-1 Rear Axle Upgrade Hardened Steel #45 with 6061 Alloy Body SXO1277RH by GPM  [SXO1277RH]

Rear axle assembly for TRAXXAS XO-1

This RC-scale rear axle assembly is made for the TRAXXAS XO-1 platform to handle rear driveline and wheel power transfer. The centre axle uses hardened steel #45 paired with a 6061 T6 aluminium body to give improved stiffness while keeping mass low for sharper response.

The assembly employs a CVD-style joint to aid smooth rotation under load and a retractable-style layout to provide extra clearance for the rocker and rear suspension travel. The design is intended as a direct replacement or upgrade where a firmer axle and alloy housing are needed for tuning or tougher use.

The kit supplies the small hardware required to assemble the unit: CVDs and fasteners are included to match the set layout, so you can replace the rear axle assembly without sourcing separate drive pins.

For hobbyists adjusting driveline response on the XO-1, this axle set offers a straightforward upgrade to raise component stiffness while controlling weight; verify fitment, suspension clearance, and fastener torque during installation using standard RC practice.
