2005-2026 Powerstroke 4x4 Leveling Springs (8663-25)

Fits

Note: These springs are ONLY compatible with 4x4 front axle models.

Give your Super Duty the aggressive stance it deserves without sacrificing the smooth ride quality you expect from a high-end hauler. These Synergy leveling springs provide a 2.5-inch lift for your 4x4 Powerstroke, utilizing a progressive-rate design that soaks up pavement chatter while offering heavy-duty bottoming resistance when the pavement ends. Manufactured from 5160H spring steel right here in the USA, these coils are pre-set to ensure your front end never sags, keeping your truck level and trail-ready for years to come.
