Skyjacker Softride 4" front spring for 1999 and up Super Duty diesel engines is a progressive multileaf pack made from American steel. Leaves are shot-peened to improve tensile strength and preserve spring life while allowing greater wheel travel and ride quality. Bolt-style spring clips reduce binding, and tapered leaf shapes distribute load evenly. Skyjacker specifies OE-or-better load capacity and supports the springs with a limited lifetime warranty.
