Product Description

Level 3 Three-Way Adjust Coilover Suspension Kit
Built by Roush to be the supreme suspension upgrade to your S550, the Level 3 three-way adjusting coilover suspension kit is the way to go for your road-course Mustang's competition! Corner and handle better than any other suspension on the market so you can maintain higher speeds through turns to pass up your competition! Not only does this coilover kit prepare your S550 for the track, it also lowers your Mustang 1.5" in the front and 1.0" in the back. On top of that drop, the Level 3 Coilover Kit from Roush also allows ride height adjustment from the standard drop so you can fine tune your S550 to look and perform to your expectations! Late Model Restoration carries everything that you need to beat the competition and improve your 2015-2018 Mustang's suspension!

Roush Performance
Roush has been making the highest quality parts in the industry for a while now, and their coilover kits are no exception. To put it lightly, there's a reason that Roush has their own Mustang line since 1997. The amount of suspension improvement - even in the brand new 2015-2018 Mustang - is beyond dramatic. If you're looking to be competitive and run a great name-brand high-quality product on your track car, or even have some fun when daily driving, this Roush Coilover kit is the upgrade that you've been looking for.
