This 3" rear leveling lift kit for 2004–2020 Ford F-150 uses fabricated steel rear lift blocks and extended U-bolts to help correct factory rake, add rear ground clearance, and create room for larger tires while maintaining a factory-like ride feel. Actual net rear lift depends on the factory rear block: 2004–2008 4WD models with a 2" stock block gain about 1" additional lift, 2009–2020 4WD models with a 1.5" stock block gain about 1.5" additional lift, and 2004–2020 2WD models with no stock block gain about 3" lift. The heavy-duty carbon steel blocks feature a cross-gusset, dual-pin design for stable axle location, are tapered to help correct pinion angle, and are finished with a textured black powder coat for added corrosion resistance. The extended U-bolts are zinc-plated, heat-treated SCM435 steel to provide strong, durable clamping force. Bolt-on installation includes instructions and requires no drilling or cutting; typical install time is about 2–3 hours with basic tools.
