Looking for just the right height but cannot seem to find springs to meet your needs in both ride quality and stance? Look no further than Steeda's S550 Mustang Adjustable Rear Ride Height Kit. With the ability to lower the rear of your S550 Mustang from 3/4" to 1-1/2", this kit allows you to dial in the ride height to your liking. The rear Ride Height Adjusters are made from billet 6061 aluminum in-house and Hardcoat anodized for the ultimate in strength and protection. These simply install above the rear springs and come with an included wrench to allow you to adjust your height with ease. The Steeda kit is also designed with a locking set screw to hold your adjustment in place. Add in Steeda's Pro-Action Shocks for even more rear control and reduced wheel hop and body oscillation and you have a winning combination!
