These custom progressive rate springs are designed for the Ford Raptor F150 GEN 1 (2010 - 2014). At the mid perch setting this set of springs will give you about 2.5" of lift in the front of your truck, while still providing a great ride.
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 will be required depending on your tire and offset.
Simply change the spring and you are ready to roll. Wall mounted spring compressor recommended.
