Lead times vary by part and some items are built to order, so please allow extra time.

The dual-rate design keeps the suspension compliant over small road irregularities while firming up progressively under hard compression, which matters when a loaded Super Duty hits a washboard or a sudden dip at speed. ICON guarantees the coil springs will not sag over the life of the vehicle.\u003c\/p\u003e\n\n\u003ch2\u003e4-Link Geometry and Adjustable Track Bar\u003c\/h2\u003e\n\u003cp\u003eThe Stage 4 kit adds ICON's 4-link front upper and lower links alongside a 4-link frame bracket kit, replacing the geometry the radius arm drop-down brackets alone would leave behind. The included adjustable track bar with FK rod end corrects front-axle centering after the lift, so steering feel and tire clearance stay consistent rather than drifting toward one fender. Together these components account for the 50% increase in wheel travel and the reduction in body roll the system is engineered to deliver.\u003c\/p\u003e\n\n\u003ch2\u003eClearance and Towing Preserved\u003c\/h2\u003e\n\u003cp\u003eAt 4.5 inches of lift, the system clears 35-inch tires on OEM wheels without modification; 37-inch tires fit with minor fender trimming.
