KellTrac Rear Adjustable Ride Height Kit, Billet (KTI-ASP-RR) - 2021–2026 Ford F-150 Raptor
The KellTrac Rear Adjustable Ride Height Kit is an industry-first solution designed for Raptor owners who want precise control over rear ride height while retaining the factory suspension. Whether you’re tired of the stock raked stance or want to fine-tune your truck’s height for performance, appearance, or load balance, this billet system delivers unmatched flexibility without changing coil springs.
Engineered specifically for the 2021+ F-150 Raptor, this adjustable kit allows you to lower the rear by up to 1.375 inches or raise it up to 1.00 inch over stock—making it perfect for leveled, reverse-drop, or mildly lifted rear setups. It installs cleanly, bolts directly into the factory suspension, and maintains OEM ride quality while giving you control Ford never intended.
Machined from massive billet aluminum and finished in KellTrac’s exclusive Tumble Black coating, this system is built for durability, strength, and long-term reliability. If you want to keep factory suspension performance but ditch the factory stance, this is the solution.
