Air suspension systems for the 1990-1993 Mustang platform are a great way to enhance cornering ability and improve ride quality over factory components. Ridetech strives to exceed expectations when it comes to performance handling and ride quality and this package checks each off those boxes. The system uses quality components designed specifically for the Mustang platform and come from our ISO 9001 certified facility in Jasper, Indiana.

This Currie F9 rear end has stock suspension brackets installed in the stock location for an easy bolt-in installation, and urethane upper control arm bushings are installed in the upper control arm housing brackets. The Southwest Speed 3rd member is the perfect compliment to the Currie rear end. It comes completely assembled and ready to bolt in the Currie housing, with a 31 spline posi-trac unit, premium ring & pinion, and solid shim set. This kit comes with a 3.70 ratio gear, which is a good cruising ratio. We have ratios from 3.50 to 5.00 that can be substituted in for no additional cost. If you would like a different ratio besides the 3.70, just make sure to request that.

Wilwood brake kits consist of specifically engineered & matched groups of components designed to provide superior brake system performance & custom appeal over a wide range of applications. These kits are the perfect compliment to wheel, tire, and suspension upgrades. Each kit is engineered specific for each vehicle.

We offer numerous configurations of these kits with many different options. Scroll to the bottom to the "Also Available" section to see everything we have in stock and ready to ship to you today.
