Hi everyone,

Our engineering team has been hard at work developing new upgrades for your S550, and we're really excited about our two innovative differential bushing inserts!:

Steeda S550 Mustang Adjustable Differential Bushing Insert System - Urethane (2015 All)

Steeda S550 Mustang Race Differential Bushing Insert System - Aluminum (2015 All)

Steeda S550 Mustang Differential Bushing Insert System - Street to Full Race Combo Kit (2015 All)

Adjustable Differential Bushing Insert System - Urethane 555-4439, $99.95:

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! Our 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 our exact specifications and durometers, our kit comes with 2 different bushing options - 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 in addition to grade 10.9 hardware with zinc-plated washers.

Race Differential Bushing Insert System - Aluminum 555-4440, $94.95:



We also knew we needed a kit for the hardcore racers out there! Made in-house from billet 6061 aluminum, 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. Aluminum bushings are included for both the front and rear differential mounting locations in addition to grade 10.9 hardware with zinc-plated washers.

Please note: This is a race-only part. It will increase NVH and gear noise.

For the small amount more the Steeda kit will cost you, you will be saving so much more on labor (over 3 hours) when comparing to competitors' kits. Here's a link to our combo kit 555-4442.
