Steeda S550 Ford Mustang Rear IRS Subframe Support Braces

Reinforce your late-model Ford chassis with Steeda S550 Mustang rear IRS subframe support braces. These chromoly steel aftermarket stabilizers connect three key points on either side of the undercarriage: the rocker panel, the front mount of the rear suspension subframe, and the rear mount of the lower control arm. This adds much-needed rigidity and overall control of the vehicle. Steeda braces will limit twisting and vibrations for improved cornering, less wheel hop, and no additional noise. The stiffeners use existing holes in the chassis, and require no modifications—installation takes about an hour with regular shop tools. Leave the factory bracket in place; these subframe braces offer twice the support. Enjoy better handling and a safer ride with a pair of Steeda S550 Ford Mustang rear IRS subframe support braces.

Steeda Hardcore Differential Support Brackets

Steeda Hardcore differential support brackets are engineered to dramatically strengthen the factory independent rear suspension by locking the differential in place and redistributing load away from the vulnerable front mounting ears. Developed to prevent housing damage under hard launches, these heavy duty, bolt in brackets reduce wheel hop, minimize pinion rise, and significantly limit differential movement so more power is transferred to the ground instead of being lost through bushing deflection. Steeda's triple shear mounting configuration eliminates the factory single shear weakness, increasing load capacity and durability, while upgraded hardware adds an extra margin of safety for high traction tires and aggressive driving. Ideal for performance focused builds, Steeda Hardcore differential support brackets deliver improved drivetrain stability, consistent launches, and enhanced reliability when traction and power are pushed to the limit
