On the front of THE 04/05 RAM SRT10 they make a dramatic improvement in the way they handle, with quicker steering response and greater vehicle control. Whatever your demands, proper alignment (caster and camber) is better maintained by the use of the correct performance durometer of the bushing’s material formulation, control arm bushings are full-floating and non-binding… especially important when ride height is altered or greater suspension load is required. Most are pre-lubricated. This is especially important for both lowered and raised vehicles that have had drastic suspension geometry modifications. performance polyurethane control arm bushings do not rot or deteriorate from oils or atmospheric conditions such as ozone, smog, road salt, chemicals, and other corrosives. They will not deteriorate in a few short years and cause that mushy, uncertain steering response- like rubber O.E.M. ones often do. Most sets come with zinc plated outer metal shells.
