Steeda Autosports has once again taken the S550 Mustang to the next level of performance and comfort with our exclusive Adjustable 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! Now also available for Ecoboost Mustangs!

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, Steeda’s does not! Steeda's Urethane kit installs in under 1 hour, adds ZERO 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, 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. For a Full Race options we offer an Aluminium insert bush instead of Urethane, or get the best of both worlds with our "Street to Race" pack, which includes both options

Steeda’s 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.
