These custom progressive rate springs are designed for the Ford Raptor F150 GEN3 (2021-2025)
This set of FRONT progressive springs will give you about +1.5" of lift in the front. 37pp & R trucks lift is a little different because this truck starts out taller in the front.They are going to be a stiffer ride than stock and 10% stronger.
These springs will work with the live valve suspension. Recalibrating is not required but you are welcome to have it done.
They will accommodate up to a 37" tire. Inner fender trimming may be required depending on your tires and offset.
Simply change the spring and you are ready to roll. Wall mounted spring compressor recommended.
