Steeda Hardcore Rear Adjustable Ride Height System (555-8176) - 2015–2026 Mustang
Take full control of your Mustang’s stance and performance with the Steeda Hardcore Rear Adjustable Ride Height System. Engineered for S550 and S650 owners who demand both strength and adjustability, this kit delivers coilover-like precision without the added chassis stress. Whether you’re carving corners or launching down the strip, Steeda gives you the confidence to dial in your setup and dominate.
Race-Bred Versatility
Developed on Steeda’s proven HPDE and competition race cars, this system was built to perform where it counts. Road racers will appreciate the ability to corner balance and fine-tune suspension geometry for maximum grip and faster lap times. Drag racers will love the extra clearance for wide tire setups and the ability to return to a street-friendly ride height after a weekend at the track—all with a simple 1/2" ratchet adjustment.
Lighter, Stronger, Smarter
Weighing up to 48% less than factory springs, the Hardcore system reduces unsprung weight for sharper handling and improved responsiveness. Precision CNC-machined from billet 1018 steel and hardcoat anodized 6061 aluminum, it’s built to take punishment and deliver consistent performance season after season.
