Our custom progressive front leaf springs are available in a 4" or 6". These springs are custom made right here in Oregon and are modeled after 99-04 super duty application/dimensions. These are not bolt-in on a stock OBS Ford Truck. They are longer than the original front leaf springs. You must use a front shackle reversal for a 99-04 front springs in order to use these on your truck.
A set of these front leaf springs paired with Sky's 2" front shackle reversal will give you a 6" or 8" lift. Leaf springs are sold in pairs and can not be sold individually.
