Condor Speed Shop - Differential Bushing - 325 IXOur 325ix differential bushing is designed for the street and the track. We use UHMW in all our suspension bushings because it is stiff, has almost zero deflection yet also absorbs some vibration. It will outlast other types of rubber or urethane bushings. With our solid diff bushing, you won't have to worry about any more rubbery flex in your diff during hard acceleration. Fits: BMW 325 IX
