Steeda Autosports has once again taken the S550 Mustang to the next level of performance and comfort with exclusive Adjustable Urethane Differential Mount Bushing Insert System for all 2015-2019 Mustang EcoBoost! When engineers sat down to design this kit, they had to come up with a way to increase performance without sacrificing an ounce of drivability all while keeping the car quiet!

Steeda’s kit installs in under 1 hour, adds little to no increase in NVH, is adjustable, and can be easily removed – it simply doesn’t get any better than this!

Minimize pinion angle changes, increase traction, eliminate wheel hop, and differential deflection with Steeda’s new kit. Made from high-strength urethane to Steeda’s exact specifications and durometers, the kit comes with 2 different bushing options – our red ‘street’ 80 durometer bushings and our black ‘performance’ 90 durometer bushings. Both bushing options will increase performance with no increase in NVH, a Steeda-exclusive.

Steeda’s kit adds the strength and supports the OEM bushings need to perform the way our customers intended. Once again, this is not a permanent modification – there is no drilling, cutting, or pressing required. Simply loosen and remove a couple of bolts and this kit installs in less than 1 hour. Bushings are included for both the front and rear differential mounting locations. Grade 10.9 hardware is included with zinc-plated washers.

Note: For hardcore enthusiasts that want ZERO pinion deflection, try the race-use only kit, as it will increase NVH and gear noise.
