BMR Suspension Differential Hardware Upgrade Kit (RH017) - 2015-2026 Ford Mustang S550 & S650
Launch harder, eliminate wheel hop, and secure your rear end with the Differential Hardware Upgrade Kit (RH017) from BMR Suspension. When high horsepower and sticky tires are applied to the ground, the factory IRS (Independent Rear Suspension) differential mounting bolts on the 2015-2023 S550 and 2024-present S650 Mustangs are highly prone to bending, stretching, or completely shearing. BMR’s upgraded hardware kit replaces weak factory fasteners with ultra-strong, heavy-duty hardware designed to handle aggressive launches, street performance, drag racing, and track day handling applications.
This premium hardware upgrade package features zinc-coated Grade 12.9 metric fasteners, offering maximum shear and tensile strength to lock your differential in place. It is specifically engineered to work seamlessly alongside BMR’s popular differential bushing insert kits (like the BK051 or BK054), as well as other aftermarket differential lockouts and inserts currently available. By upgrading to this high-tensile hardware, you ensure that your rear differential stays firmly located under load, protecting your driveline components and transferring more power directly to the tires. Proudly designed and manufactured in the USA!
