2015-2018 Mustang GT Steeda Adjustable Differential Bushing Insert System, Polyurethane

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 2015-2023 Mustang EcoBoost! 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, Steeda's 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 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.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.Product BenefitsLimits IRS differential movement while increasing traction and eliminating wheel hopLittle to no increase in NVH unlike the competitionEasily removable, not a permanent modification100% designed, manufactured and made in the USAInstalls in 1 hour or less
