Overview

Put the power down with this billet aluminum differential brace and maintain control with the subframe supports from Steeda! During testing, Steeda found that the differential bushings were being stretched to their limit with hard launches, so Steeda set out to disperse the load and minimize rear differential movement. After resolving the differential movement, Steeda observed significant movement in the subframe. The subframe bushing supports allow the stock bushings to absorb vibrations and noise but prevents them from flexing excessively.

Billet construction. To keep the parts lightweight yet ultra-strong, Steeda CNC machines the brace and bushing supports from 6061 billet aluminum at their Valdosta, GA location.

Better performance. With 50% more attachment points than the competition and a dual bushing design, you can be confident this brace will outperform. An optional stiffer durometer bushing set can be added to the kit for those that are looking for maximum performance at the track and do not mind minor NVH.

— Why we stock Steeda

OE-style engineering, in-house manufacturing, race-proven on Steeda's own SCCA program.

Steeda has been engineering Mustang — and now Explorer, Focus, F-150, and Maverick — parts in Valdosta, Georgia since 1988. CNC-machined billet, proprietary CAD-driven suspension geometry, and a factory SCCA Majors road-racing team that runs their own parts on the track every weekend. When you bolt a Steeda part onto your car, it's the same part Steeda's own race cars run.

We carry Steeda because the fitment is right the first time, the warranty is real (lifetime on Steeda-manufactured parts), and the install instructions don't leave you guessing. Drop the car at our Thousand Oaks shop and our techs handle the fit-up — or order with confidence and run it yourself.
