Polyurethane Differential Bushing Lockout Kit

The BMR BK051 is a polyurethane differential bushing lockout kit specifically engineered for 2015-2026 Ford Mustangs, including V6, EcoBoost, GT, GT350, and GT500 models. Manufactured in the USA from 95-durometer polyurethane, it offers a precise fit and superior performance compared to the factory rubber bushings. The primary benefit of the BK051 kit is its ability to minimize wheel hop and enhance rear-end stability. By reducing differential movement and pinion rise, it promotes optimal performance for street performance, drag racing, and handling applications. Despite its performance enhancements, the kit is designed not to sacrifice NVH (noise, vibration, and harshness) levels, providing a balance between improved handling and a comfortable ride. The polyurethane material used is known for its durability and resistance to undercar conditions such as petroleum products, road salt, and ozone. The installation is described as a non-permanent modification that installs over the factory differential bushing. The kit includes all necessary hardware for installation, which typically takes approximately one hour and requires light to moderate mechanical skill.
