BMR 15-17 S550 Mustang Differential Bushing Kit (Polyurethane) - Red

BMR Suspension is known for making well-built suspension components that improve the performance of street cars and race cars alike. If you're looking to get a better handle on your 2015-2024 Ford Mustang's rear end, especially if you're dealing with wheelhop or excessive differential movement, this polyurethane differential bushing kit (BK049) is a solid option. It replaces the stock rubber bushings, which can break down over time and deflect too much under load, with a much stiffer polyurethane material.

This kit uses 95-durometer polyurethane, which is a firm material that significantly reduces how much the differential can move around. This means more consistent power delivery, especially when launching the car hard, and a more stable feel during aggressive driving. BMR also includes heavy-duty hardware with this kit. While not always necessary, this upgraded hardware is a good idea if your Mustang has higher than stock horsepower or if you plan on frequent hard launches, as it helps prevent potential failures of the differential mounting bolts under extreme stress. Keep in mind that installing this hardware upgrade requires minor modifications to the rear differential mounts.

This kit is designed for street performance, drag racing, and handling applications, and it's proudly made in the U.S.A. Installation typically takes about 3-4 hours, depending on how easily the old bushings come out.
