Dual Mount Rear Differential Bushing Kit

The Revshift Dual Mount Differential Bushing Kit is engineered to replace the stock rubber differential bushings on BMW F80, F82, F83, and F87 M3/M4/M2 models. This upgrade includes a secondary rear bushing and a dual mount bracket, adding a crucial mounting point to the vehicle's subframe. By securely anchoring the differential, this kit effectively eliminates wheel hop and significantly improves the car's overall handling dynamics. The kit utilizes a robust two-piece bushing design that sandwiches the subframe, ensuring a locked-in and stable configuration that prevents the common shifting or twisting issues found with single-piece designs. The dual mount bracket has been meticulously crafted for both strength and an exact fit. Constructed entirely in the USA, the bushings are made from Revshift's proprietary 95A polyurethane formula and paired with CNC-machined 6061-T6 billet aluminum components. The package includes new class 10.9 bolts for the rear bushings, along with Revshift's specialized bushing lube and threadlocker for a complete installation. This kit is available in two hardness options: 80A (Street - Black), which offers a slight improvement in stiffness over OEM rubber with no significant increase in Noise, Vibration, and Harshness (NVH), making it suitable for an "OEM+" feel. The 95A (Track - Green) option provides a substantially stiffer and stronger bushing, ideal for performance-oriented street cars and track use, though it may introduce a minor increase in NVH. The product is backed by a lifetime warranty and sold as a complete set.
