09-15 CADILLAC CTS-V DIFFERENTIAL BUSHINGS
These polyurethane bushings replace the low quality, factory installed bushings in the differential. If there is a “clunking” sound coming from the rear of your vehicle during acceleration, the differential bushings are a probable cause. The rubber material that the factory used for these bushings is very soft with considerable air space in the bushings, and these bushings are under tremendous strain during vehicle acceleration. These three points lead to the early demise of the factory bushings.
Our replacement bushings are made using a polyurethane material that is stronger than the OEM rubber and the bushings are 100% filled (no air space) which minimizes deflection between the inner aluminum tube and outer housing. The use of our bushings will add minimal noise transmission to the cabin from the differential.
We offer two different durometers (hardnesses) for either a daily driver-street car or a full on race car. With that said, here is a breakdown of what we suggest a customer purchases dependent on the use of the vehicle-
- Daily driver/occasional racing (700hp or less)- We suggest the kit in black. This will keep the differential in place without transmitting too much noise or vibration.
- Race car or noise isn’t a concern (unlimited HP)- We suggest the kit in red. With our red bushings the differential will be held in place and have a hard time moving. With the full red set you might notice noise as the polyurethane is a lot stiffer than the factory bushings as well as our black bushings.
