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.

Note: We are currently out of the 4" springs. We are hoping to have these available and back on the website by the end of February. If you have any question please email orders@obssolutions.net
