Get your Mustang S550 low without sacrificing ride quality. Air Lift Performance air spring suspension gives you maximum drop with superior handling, a sharp steering response, and a comfortable ride. With a huge range of damping adjustment and lightweight components (lighter than coilovers), you can’t choose a better lowering kit for your ride. Add the versatility of the monotube dampers—for the best performance on both the track and the street—and Air Life Performance is a no-brainer for your Mustang. In the rear, we have replaced the coil spring with our compact, double-bellows air spring to match the ride quality with that of the front. We also replace the shocks with our own 30-level damping adjustable monotube shocks for the ultimate in handling performance. This kit looks almost as sharp as it performs, with bright red accents on a black chromed shock body with gloss black powder-coated spring brackets. As you can see, we have included everything to allow you to drop the rear of your Mustang 5.1in from stock! As the leader in air suspension products for over 70 years, Air Lift is committed to delivering quality parts that last. To ensure longevity for the customer, the key suspension components have been track-proven and tested on a durability rig for over one million cycles, which equates to 100,000 miles. With a one-year, unlimited-mileage warranty—not to mention the Air Lift Performance reputation for great customer service and technical support— you can purchase this kit with peace of mind.
