2.5" vs 3.5"  Explained

These springs—and many others—are labeled 2.5"/3.5" for Ford trucks because starting in 2020, Superduty models dropped 1" lower from the factory compared to earlier years. So, a 2.5" leveling coil on a 2005-2019 Superduty lifts 3.5" on a 2020+ model without swapping any other parts. The exception? The 2020+ Superduty TREMOR, which already comes with a 2" lift, making it taller than older models. Slap on these 2.5"/3.5" springs, and you’ll raise a 2020+ TREMOR’s front by 1.5".
