BMR Releases S550 Mustang Differential Bushing Lockout Kit


New from BMR Suspension – the Polyurethane Differential Bushing Lockout Kit for 2015+ Mustangs reduces wheelhop and pinion rise while enhancing rear stability. See more details below.

Official Release:

Reduce wheelhop and pinion rise, and enhance the rear stability of your 2015 and newer Mustang by reducing differential movement with a Polyurethane Differential Bushing Lockout Kit from BMR Suspension. Stock rubber bushings with voids are great for minimizing NVH, but cause wheelhop and damage to rear suspension parts. Designed from 95-durometer polyurethane, these diff bushing lockouts greatly reduce deflection, differential movement, and pinion rise that you experience with the factory bushings.

BMR’s Polyurethane Differential Bushing Lockout Kit (BK051) transfers more power to the differential by not absorbing it with wasted movement. BMR designed the BK051 for street performance, drag race, and handling applications, making them the perfect wheelhop solution for performance-based S550 Mustangs. Each lockout is molded to strict tolerances, which ensures high quality and a perfect fit. These greatly reduce differential movement, increasing handling stability and giving you a much-improved overall feel in any performance driving situation. Installation time is about 1 hour. Proudly made in the U.S.A.!
