Air Lift Performance Rear Air Suspension Kit — Mustang S550 (2015–2023)

Air Lift Performance engineered this rear kit to deliver maximum drop and real performance. Progressive-rate air springs, lightweight components (lighter than stock coils), and 30-click monotube dampers give you a huge tuning window—from super-soft to race-car-stiff. Key components are durability-tested over one million cycles (~100,000 miles) and backed by a one-year, unlimited-mileage warranty.
