ISR Performance Differential Bushing Set - Hyundai Genesis Coupe 09-12 BK1

The ISR Performance Differential Bushing Set for the 2009-2012 Genesis Coupe BK1 replaces the factory soft rubber differential bushings with a multi-piece Delrin and aluminum design. Adds a 4th bushing position not present from the factory, which is the key change that prevents the differential flex that destroys factory diff covers under hard driving.

What It Does

Genesis Coupe BK1 chassis ship with very soft factory bushings. 2 front and 1 rear. and that's it. Under hard driving (drift, track, or just aggressive street use), the differential moves significantly in its mounts. Once those rubber bushings wear, the diff can flex enough to crack the differential cover. That's an expensive failure mode for a wear item that should never see that kind of stress.

The ISR multi-piece bushing replaces the factory rubber with hardened Delrin bushings and aluminum sleeves, eliminating the deflection that caused the problem in the first place. The kit also includes a 4th bushing that adds a reinforcement point the factory configuration doesn't have, further stiffening the diff mounting.

Fitment
