Whenever you lower a vehicles ride height, negative camber is increased and should be corrected to ensure even tire wear. How much correction depends on the vehicle and the reduction in ride height. H&R Triple C Camber Adjustment Bolts are a simple means of removing excessive camber, adjusting your vehicles camber settings, or even correcting small side-to-side camber variations for precise alignment. H&R patented Triple C Bolts replace the original upper fastening bolts on McPherson strut applications. Price is for a set of two (2) bolts.
