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 excellent ride.
They will accommodate up to a 37" tire. Some inner fender trimming may be required depending on your wheel offset. No spacer required, simply change the spring and you are done.
