Product Specs: Vehicle: 04-08 Ford F150 Drivetrain 4x4 Addl Info. 2 Stage Springs Notes This product has the full Skyjacker product warranty Skyjacker Terms : SoftRide Technology Soft Ride Technology enhances every steely aspect of leaf spring performance, giving you all the vigorous off-road handling needed while providing the smooth street riding characteristics that you demand. Skyjacker's advanced method of shotpeening, tapered leafs, Teflon wear pads and 'presetting' process achieves articulation at its best... without sacrificing the life of the spring. Shotpeening Spring leaves are blasted with hard, steel pellets (or shot), which increase the tensile strength. Without shotpeening, the maximum wheel travel cannot be achieved without sacrificing the life of the spring. 2-Stage Skyjacker adds an overload spring leaf to most rear spring applications to provide load capacity without affecting the ride quality. The second stage engages and maintains the strength when extra weight is added or towing. Top Gun Customz is an Authorized Skyjacker Dealer. We sell a full line of the Skyjacker products as well as many other Top Manufactures.
