The new EZ Cam(tm) XR is designed for non-slotted struts. It allows both positive and negative camber changes up to approximately 1.75 degrees (depending on vehicle) by replacing the upper O.E. strut/spindle bolt. This easy to use adjuster provides built-in adjustment over the life of a vehicle just by rotating the head of the bolt. Each kit contains two cam bolt assemblies, enough for both sides of the vehicle.
