If you make big power, you need our 14mm diff bolt upgrade. We supply an OEM BMW 10.9 14mm bolt and the matching front differential bushing. *Please note that you will need to drill the diff casing & tap to M14x1.5 with our upgrade kit.

Our E36 & E36 M3 Differential Bushings are designed for the street and the track. You won’t have to worry about any more rubbery flex in your diff mounts during hard acceleration. We use UHMW in all our suspension bushings because it is stiff, has almost zero deflection yet also absorbs vibration. It will outlast other types of rubber and polyurethane bushings.

Fitment: all E36s including the M3

• Original Diff Kit includes all 3 differential bushings.
• 14mm Diff Bolt & Bushing Kit includes 14mm bolt and 3 differential bushings.
