Steeda was the first company to introduce S550 Differential Bushing Inserts all the way back in early 2015. Not only was this kit designed to completely fit around the stock bushing cutouts, but they came in two different durometers, 80 and 90 durometer.
It’s been common practice to share the extra bushings (the ones not used) with a friend. So Steeda came out with a hardware kit designed just for that!
- Contains all hardware needed to install extra 555-4443 bushings
- Perfect for sharing your extra bushing set with a friend
- High-quality Steeda hardware
- Made in USA
Note: This is a HARDWARE ONLY kit. Bushings sold separately (see 555-4443 Differential Bushing Insert System).
Fitment: 2015-2023 Ford Mustang GT, EcoBoost, V6 (NOT GT350, Mach 1, or GT500)
