Steeda Adj Differential Bushing Insert System (2015-2023 Mustang / 2024 Mustang) 555-4443

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.  This product may increase noise, vibration, and harshness (NVH) after installation. NVH may increase slightly with red/street bushing inserts, but more aggressively with black/performance bushing inserts. This product itself does not generate any additional NVH, rather it transmits existing rear differential noise into the cabin by firming up the OE bushings.
