TRAXXAS Xo-1 Aluminium Rear Diff Case XO013 Upgrade by GPM  [XO013]

Aftermarket aluminium rear diff case for Xo-1 tuning

This aluminium rear differential case is designed for the TRAXXAS Xo-1 chassis and supplied as one set for RC-scale use. It replaces the stock rear diff housing to provide a robust aluminium option for hobbyists working on setup and maintenance.

The part is offered as an aftermarket housing and acts as the primary enclosure for the rear differential; it mates with the Xo-1 gearset, bearings, and standard mounting locations. When fitted correctly it supports common setup tweaks without altering core drivetrain geometry.

Assembly advice: perform the usual rear diff strip and move internal gears and bearings across unless replacing them. Confirm correct gear mesh and bearing preload when reassembling, use suitable hex tools, and apply thread-lock where steel fasteners engage aluminium threads.

Select this aluminium rear differential case for a sturdy aftermarket housing when maintaining or tuning the Xo-1; always recheck alignments and bearing fits before running.
