Steeda S550 Mustang Race Differential Bushing Insert System - Aluminum GT/EcoBoost (2015-2021)
Steeda Autosports has once again taken the S550 Mustang to the next level of performance with our exclusive Billet Aluminum Differential Mount Bushing Insert System for all 2015+ Mustangs GT/EcoBoost! When our engineers sat down to design our street kit, we knew we needed one for the hardcore racers out there, too!
Steeda's race kit installs in under 1 hour, is adjustable and can be easily removed - it simply doesn't get any better than this!
It eliminates pinion angle changes, wheel hop, differential deflection all while increasing traction! Made in-house from billet 6061 aluminum.
Steeda's kit adds the strength and support the OEM bushings need to perform the way our hardcore racers intended. Once again, this is not a permanent modification - there is no drilling, cutting or pressing required. Simply loosen and remove a couple bolts and this kit installs in less than 1 hour. Aluminum bushings are included for both the front and rear differential mounting locations. Grade 10.9 hardware is included with zinc-plated washers.
Note: This is a race-only part. It will increase NVH and gear noise. For street and competition use, try our 555 4443 kit with urethane bushings.
Note: Does not fit GT350 or Mach 1. Due to changes in the OE subframe bushings, the bushing inserts will not fit 2021 GT500's or 2022 Mustang's.
