Description

These Axiom Supply dual rate front coil springs are built around the front axle weight of a diesel Super Duty, not adapted from a gas application. The dual rate design rides close to stock unloaded and stiffens as load comes on, so the truck stays composed with a camper, plow, or trailer on the pin. Expect roughly 2.5" of front lift on 2005-2019 trucks and roughly 3.5" on 2020+ trucks, since Ford dropped the factory front ride height about an inch in 2020. On 2020+ Tremor models that already carry a factory lift, figure on about 1.5" of additional front height.

Part Number: AXFDC25
