This optional left-side front upper A-arm holder is intended for the YD-4 series and is supplied by Yokomo under model Y4-302UHL. The part is machined from aluminium with a black alumite finish and the chamfered edges help reduce sharp contact points when assembling components.
When fitted at the upper A-arm attachment the bracket improves mounting accuracy and gives the upper arm greater structural rigidity, which refines steering feel and the consistency of the suspension linkage. The chamfered edge also aids in smoother fitment and lowers the likelihood of interference during setup changes.
Use this holder to ensure dependable steering performance and to simplify precise adjustments on YD-4 based touring car configurations.
