Product Details

BMR Suspension Differential Bushing Lockout Kit (Polyurethane) is made for the 2024-2026 Ford Mustang (S650). Stock rubber bushings are designed with large voids that absorb NVH but do nothing for performance. BMR's Differential Bushing Lockout Kit (BK051) uses high-durometer polyurethane to reduce bushing deflection for street performance, drag racing, and handling applications.

Installs over the factory bushings and fills the space between bolt and bushing cup. Please note: BMR's BK051 is not compatible with S550 GT350s, S550 GT500s, and S650 automatic Dark Horses due to these vehicles having a unique rear driver side differential mount bushing. BMR Suspension designs and builds this part in the U.S.A.
