TRAXXAS XO-1 Harden Steel #45 Rear Axle w/ Alloy Body by GPM SXO1277RH  [SXO1277RH]

Rear axle set for XO-1

This is an RC-scale rear axle assembly designed for the TRAXXAS XO-1 platform, built to handle power transmission and wheel drive duties on the rear driveline. The component combines a hardened #45 steel axle section with an aluminum 6061 T6 alloy body to balance strength and reduced mass for handling and responsiveness.

The axle uses a CVD-style connection to promote smooth rotation under load, and a retractable-style layout that provides additional clearance for the rocker and rear suspension movement. The design intent is to replace or upgrade the rear driveline components where a stiffer axle and alloy housing are desired for tuning or durability improvements.

The product includes small hardware items needed to complete the assembly: CVDs and fasteners are supplied to match the set configuration, allowing straightforward replacement of the rear axle assembly without sourcing separate drive pins.

For hobbyists tuning driveline response on the XO-1, this axle set serves as a direct upgrade option to increase component stiffness while keeping overall weight low; inspect fitment and clearances during installation and confirm hardware torque values with standard RC practice.
