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 2015-2019 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, 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 and the included differential bolts are grade 12.9.
The S550's subframe mounting holes are very large compared to the subframe mounting bolts. Since there is a large difference in bolt and hole size, the subframe can be mis-aligned from the factory up to 1/2" left to right.
The Steeda S550 Mustang IRS Subframe Alignment Kit is made from CNC-machined Delrin to avoid putting two dissimilar metals next to each other, preventing corrosion. Delrin is also less weight then aluminum or steel inserts and therefore keeping performance in mind. The Delrin sleeves slide into the subframe mounting holes, and fill the extra space left between the subframe mount and bolt from the factory.
Our Steeda S550 Mustang IRS Subframe Alignment Kit guarantees that the subframe will be bolted to the same location every time it is lowered. Eliminating the need for unnecessary alignments..
This combo includes Steeda's popular differential bushing bolt upgrade kit 555 4448 , IRS Subframe Alignment Kit 555 4438 and adjustable differential bushing insert system 555 44 43.
