This aluminium rear knuckle arm is supplied as a direct-fit replacement for the TRAXXAS XO-1 rear assembly and is intended to match the part reference in the title without implying vehicle-level changes. The 3.5 degree value denotes the rear correction angle used for controlled chassis geometry adjustments on RC-scale platforms.
The component ships as a 1pr set and is targeted at hobbyists seeking robust replacement parts or making measured suspension and steering geometry changes. Installation requires standard RC tools and straightforward workshop practice, and the arm aligns with XO-1 rear mounting points specified in the title.
The description concentrates on fit, tuning application, and practical installation notes rather than promotional claims. Confirm current hardware compatibility prior to fitting and retain original fasteners where suitable to ensure correct assembly.
Choose this aluminium rear knuckle arm when you need a reliable replacement or when implementing small rear geometry changes on the TRAXXAS XO-1 chassis to optimise handling characteristics.
