Steeda Autosports has once again taken the S550 Mustang to the next level of performance and comfort with our exclusive Adjustable Urethane Differential Mount Bushing Insert System for all 2015-2016 Mustang GT! When our engineers sat down to design this kit, we had to come up with a way to increase performance without sacrificing an ounce of drivability all while keeping the car quiet!

Unlike our competitors' kits that will absolutely increase NVH (noise, vibration, harshness), take 3-4 hours to install and force you to permanently modify the rear IRS suspension with a sawzall, Steedas does not! Steeda's kit installs in under 1 hour, adds little to no increase in NVH, is adjustable and can be easily removed - it simply doesnt 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, our 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.

Steedas kit adds the strength and support 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 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 our 555-4440 kit. This kit features aluminum bushing inserts. For race-use only as it will increase NVH and gear noise.
