About this control arm Lower-Inner rear bush kit
The SuperPro DURO3738K front lower control arm rear bush kit uses a DuroBall bushing, a hybrid of SuperPro polyurethane and a metal spherical bearing. It gives precise location and control with free articulation and good noise and vibration manners. The double offset design also allows alignment correction, for sharper steering, more consistent handling and a longer service life than soft factory rubber.
