This precision aluminium rear arm bulk is engineered as an aftermarket replacement for the TRAXXAS XO-1 platform and supplied as a 1pc set (XO009). Manufactured with upgrade performance in mind, the component provides a metal alternative to stock parts for maintenance, tuning and high-speed durability evaluation.
Designed to match XO-1 mounting geometry, verify hole locations and suspension clearance before final fitting. The part follows a hop-up design intent to improve repeatable chassis behaviour under load.
Professional installation notes: retain or replace mounting fasteners with appropriate grade hardware, confirm alignment and full suspension travel clearance, inspect contact faces for wear and torque to specified values. Use the bulk as a direct replacement during handling refinement and durability testing.
