Show original supplier description

The Revshift 80A black polyurethane differential bushing kit is engineered to replace the stock rubber bushings in the BMW F80 M3, F82/F83 M4, and F87 M2 models. This kit directly replaces the OEM rubber components, offering a significant upgrade in differential mounting point stiffness. By reducing differential movement and twisting, these bushings enhance the vehicle's handling capabilities and drivetrain responsiveness. The bushings feature a robust two-piece design that ensures the differential is held securely in place, preventing unwanted motion during spirited driving or track use. The 80A hardness rating provides a slightly stiffer and stronger alternative to OEM rubber, offering an 'OEM+' feel with no significant increase in noise, vibration, or harshness (NVH). This makes it an excellent choice for drivers seeking improved performance without compromising daily drivability. A lifetime warranty is included, and bushing lube is provided for installation. This kit is compatible with the following BMW models: the F87 M2 (2016-2021) with the N55 3.0L engine, the F80 M3 (2015-2018) with the S55 3.0L engine, and the F82/F83 M4 (2015-2020) with the S55 3.0L engine.
