This aluminium rear knuckle arm is intended as a direct replacement for the TRAXXAS XO-1 rear assembly and mirrors the specification in the product title without implying full vehicle alteration. The stated 3.5 degree value indicates the rear correction angle used for minor chassis geometry tuning on scale RC cars.
Supplied as a 1pr set, the component is aimed at hobbyists performing suspension setup changes or swapping out damaged stock knuckles. Fitting requires routine RC tools and basic workshop skills, with compatibility for XO-1 rear mounting points as noted in the title.
The write up emphasises fit, tuning purpose, and practical installation tips rather than marketing claims. Check current hardware fitment before installing and retain factory fasteners where sensible.
Fit this aluminium rear knuckle arm to restore worn parts or to make subtle rear geometry adjustments on the TRAXXAS XO-1 chassis to refine handling balance.
