Maximize Traction with BMR Billet Lockouts

Eliminate unwanted differential deflection and improve your Ford Mustang's rear-end response with the BMR Suspension Billet Aluminum Differential Lockout Kit (BK054). Designed for the S550 and S650 chassis, this kit provides a rigid, high-performance solution to the movement inherent in the factory rubber bushing design.

Precision Machined Performance

• Constructed from 6061-T6 billet aluminum
• Drastically reduces differential movement and pinion rise
• CNC-machined for exact tolerances and perfect fit
• Lightweight design without sacrificing strength
• Easy installation for immediate performance gains

The factory rubber bushings are the primary cause of wheel hop and inconsistent power delivery in the S550/S650 Mustang. By installing BMR's billet aluminum lockout plates, you effectively brace the differential against the subframe, ensuring that power is transferred directly to the rear wheels rather than being absorbed by the soft rubber. This results in crisper throttle response, improved traction during hard launches, and a more connected feel between the driver and the road. Because these plates are machined from 6061-T6 aluminum, they provide exceptional strength while keeping weight to a minimum. This is a must-have upgrade for any Mustang owner looking to improve their vehicle's performance on the street or at the track. Experience the difference in stability with this BMR kit from GGCRACING.
