Polyurethane Differential Bushing Kit

The BMR BK049 is a polyurethane differential bushing kit engineered to significantly reduce differential movement and pinion rise in 2015-2024 Ford Mustang S550 and S650 models. This kit directly addresses wheelhop, a common issue during aggressive driving, by replacing the factory rubber bushings with 95-durometer polyurethane components. Crafted from high-density polyurethane, these bushings offer superior deflection resistance over OEM rubber, ensuring they do not break down from exposure to common undercar contaminants like petroleum products, road salt, or ozone. The bushings feature zinc-coated inner sleeves for added durability and corrosion resistance. Each bushing is manufactured to strict tolerances, ensuring a perfect fit and optimal performance for street performance, drag racing, and handling applications. BMR includes heavy-duty hardware with this kit, specifically for customers with higher than stock power levels or those who plan on launching their Mustang hard. This hardware helps combat potential differential mounting bolt failures, though it requires slight modification to the rear differential mounts. Installation is estimated to take 3-4 hours and is proudly designed and made in the U.S.A.
