Minimize wheelhop and enhance the rear stability of your 2015 and newer S550 Mustang by decreasing differential bushing deflection with a Differential Bushing Lockout Kit from BMR Suspension. The stock rubber bushing with large voids are great for absorbing NVH, but do nothing for performance. The billet aluminum plates in BMR's Differential Bushing Lockout Kit simply keep the bushing from deflecting. BMR Suspension's Differential Bushings Lockout Kit drastically decreases differential movement and pinion rise over the factory rubber bushings. BMR designed its Differential Bushing Lockout Kit from 6061-T6 billet aluminum. This material is extremely strong, without significant weight gains. Each bushing lockout plate is CNC-machined to exact tolerances. This allows for a perfect fit and increased performance for any driving style. Designed for street performance, drag race, and handling applications. BMR Suspension's BK054 Differential Bushing Lockout Kit is the perfect wheelhop solution for any S550 Mustang being used for performance driving. The kit offers huge increases in performance over the stock rubber bushings. The OE bushings are designed with air pockets and are made from soft rubber. These ?voids?, coupled with soft material produce excessive differential movement during normal and aggressive driving. BMR's Differential Bushing Lockout kit installs over the OE rubber bushing, nearly eliminating differential movement by filling the space between the bolt and bushing cup. This eliminates almost all differential movement, reducing wheelhop and increasing traction, while giving you a much-improved overall feel in any performance driving situation. BMR Suspension's BK054 Differential Bushing lockout Kit is available in a durable black finish and comes with all necessary hardware. Installation time is about 1 hour. Proudly made in the U.S.A.!
