BMR Suspension BK051 Differential Bushing Lockout Kit Polyurethane for S550/S650 Mustang

The BMR Suspension BK051 Differential Bushing Lockout Kit delivers a race-proven solution for eliminating wheelhop on S550 and S650 Mustang platforms. Engineered for street performance, drag racing, and road course applications, this polyurethane lockout kit replaces the factory differential bushings to create a solid connection between the differential and subframe.

Key Features:

• Polyurethane construction provides durability while maintaining street drivability
• Eliminates differential movement and wheelhop under hard acceleration
• Improves power transfer and 60-foot times for drag racing applications
• Maintains consistent suspension geometry during aggressive driving
• Direct replacement for factory differential bushings
• Compatible with 2015+ S550 and 2024+ S650 Mustang models

By locking out the differential bushings, this kit prevents the rear axle from twisting and hopping during launch, providing more consistent traction and improved performance. The polyurethane material offers an excellent balance between the harsh ride of solid aluminum bushings and the excessive deflection of stock rubber bushings, making it ideal for vehicles that see both street and track duty.
