The EX056 rear lower arm is an aluminium alloy replacement sold as a 1pr set for Axial EXO chassis. It replaces standard polymer lower arms where the EXO-series mounts are used, offering a stronger mounting surface for rear linkages.
In setup terms the lower arm influences roll centre, toe stability and shock mounting angles; using an alloy arm reduces flex and helps the suspension hold intended geometry under load. During installation check pivot alignment, mounting hole condition and ensure there is adequate clearance for axle and driveshaft movement.
The EX056 is suited to trail and bash use where a stiffer alloy arm helps retain suspension geometry; always trial-fit components before final torqueing.
