Introducing the Garagistic E21 Poly rear differential bushings (33171117282). Replace those old worn out, failing, 35+ year old factory E21 rubber bushings for the upgraded Garagistic polyurethane bushings! These bushings offer an upgrade in performance over the factory rubber helping to keep your differential under control and also feature the Garagistic lifetime warranty. Never have to change your E21 differential bushings again! Why upgrade your differential bushings? The differential is what transfers all the power from the engine to the two rear wheels. When the differential moves around or slops within the chassis this can cause a sense of a delay in power delivery as well as put undue stress on all the other components connected to it! Keeping the differential in alignment will help with better power transfer, and is one link in the system for an overall better performing rear end.
We offer the E21 Poly Differential Bushings (33171117282) in both 80A poly, and 95A poly. Each material has its intended application and benefits. The 80A poly is the happy medium between upgraded bushings and plush OEM rubber. It is intended for the spirited street driver, and occasional Auto-X and track use. It offers a definite increase in performance with a limited increase in noise transfer and harshness. The 95A is the next tier up on the poly scale, offering a stiffer material than 80A and increased performance to match. If you have a car with a louder exhaust and or a car intended for only weekend use in the canyons or on Auto-X and track circuit this is the bushing for you. We hope this helps you determine what is best for you!
