Product Description

The ICON K93142T Stage 2 Suspension System is the most aggressive bolt-on lift kit in ICON's F-150 4WD lineup, delivering 3.5-4.5" of front lift through a system engineered around high-strength ductile iron steering knuckles that replicate the suspension geometry of the factory F-150 Tremor. Combined with 2.5 Series internal reservoir coilovers and ICON's latest Delta Joint Pro tubular upper control arms, this system achieves a 20% increase in front wheel travel compared to standard ICON coilover kits - all while retaining factory alignment spec range.

Out back, 2.5 Aluminum Series piggyback reservoir rear shocks provide up to 2" of rear lift with vehicle-specific valving for a balanced ride front to rear. Designed for F-150 4WD owners who want maximum capability, larger tire clearance up to 34", and race-proven componentry in a fully bolt-on package - no cutting or welding required.
