These Polyurethane Rear Upper Shock Mount Bushings are true, performance rear shock mounts that drastically reduce the deflection that occurs with the factory upper rear shock mount bushings. The stock shock mount bushings deflect under load – negatively affecting the rear shock damping, especially with a modified suspension and increased shock valving. Upgrading your factory shock mount bushings to AKG polyurethane rear upper shock mount bushings will drastically reduce this movement, helping to keep the rear shock in place so that it may operate properly.
AKG's U.S. Military Spec compound has elasticity and memory. This exclusive compound allows them to manufacture a bushing with performance characteristics that are free from the deformation which plastic bushings (Delrin, UHMW) are very prone to.

These medium 85A durometer polyurethane rear upper shock mount bushings are our performance-spec compound bushings for this location (as opposed to our race-spec 95A compound). They are designed for those who want to retain a relatively comfortable ride with much improved performance over the stock bushings.
These medium-hard 95A durometer polyurethane rear upper shock mount bushings are our race-spec compound bushings for this location (as opposed to our performance-spec 85A compound). They are designed for those who are looking to obtain maximum performance out of their rear shocks for racing use.
