Rear Block Kit- 04-20 F150 4WD 3in

The ReadyLift Rear Block Kit for 04-20 F150 4WD 3in is engineered to deliver a straightforward, reliable suspension lift solution for Ford full-size truck owners seeking increased ground clearance and a more aggressive stance. This leaf spring block kit is purpose-built for trucks that require additional ride height for off-road capability, larger tire fitment, or improved departure angles without the complexity and cost of a complete suspension overhaul. Whether you're preparing your F150 for backcountry exploration or simply want a functional lift at an accessible price point, this rear block assembly addresses the core need for 3 inches of elevation gain.

ReadyLift blocks function by inserting precision-cast iron components between the leaf spring pack and the axle housing, effectively raising the spring perch and translating that geometry to vertical lift. The 3-inch dimension is measured from the OEM ride height, providing meaningful clearance gains without inducing excessive driveline angles or compromising suspension geometry excessively. Iron construction ensures durability under the cyclic loading demands of suspension travel, and the natural finish resists corrosion in typical use environments. All necessary mounting hardware is included, eliminating the need to source fasteners separately—a practical detail that reduces installation complexity and ensures proper torque specifications are met with OEM-compatible hardware.

This kit is ideal for 4WD F150 operators running model years 2004 through 2020 who want straightforward rear lift geometry without electronic suspension complexity. Professional mechanics and DIY builders appreciate leaf spring blocks for their simplicity, predictability, and minimal impact on ride quality compared to air or coil spring systems. Installation typically requires jack stands, basic hand tools, and approximately 1–2 hours per side; rear-only lift also maintains the truck's factory rake and preserves compatibility with most aftermarket wheels and bed accessories. The 21.8-pound kit weight reflects the substantial iron construction needed for long-term reliability on trucks that may carry payload or tow moderately.
