Product Description
The BMR BK051 Differential Bushing Lockout Kit is engineered specifically for the 2015–2025 Mustang (S550 and select S650 models) to reduce excessive differential movement under load. By fitting precision-molded 95-durometer polyurethane inserts around the factory bushings, it drastically reduces wheel hop and pinion rise while improving throttle response and rear traction—all without removing or replacing the OEM bushings.
This non-permanent, bolt-on solution offers a performance upgrade with minimal NVH increase. Installs quickly (in about an hour) with hardware included and remains fully reversible. Perfect for street, drag, or handling-oriented builds looking to tame the rear end without compromising day-to-day comfort.
