ReadyLIFT 2.5" OEM-Style Cast Iron Rear Block Lift Kit | 2021–2025 Ford F-150 2WD/4WD
Is This for You?
You're running a 2021–2025 Ford F-150 — 2WD or 4WD — and you need to add rear lift for towing, hauling, or to restore rake after a front leveling kit. Stacking factory blocks is illegal and dangerous. The ReadyLIFT 26-21250 is the engineered solution — a single 2.5" OEM-style cast iron rear block with integrated bump stop landing pads and cast-in center pins, designed to work in concert with your ReadyLIFT leveling kit and backed by a Limited Lifetime Warranty.
The Result
Two OEM-style cast iron 2.5" rear lift blocks with integrated bump stop landing pads and cast-in center pins deliver 2.5" of rear lift on 2021–2025 Ford F-150 2WD and 4WD applications. Based on OEM designs and never made from lightweight extrusions — cast iron construction provides the strength and durability required for towing and hauling applications. Four E-coated U-bolts, eight nuts, and eight washers are included. Ideal as a tow package upgrade for stock, leveled, or lifted trucks that need additional rear lift capacity.

Installation & Engineering Notes
All U-bolt hardware must be torqued to specification at ride height — do not torque with the suspension unloaded. Re-torque U-bolts after the first 500 miles of driving. Never stack rear blocks — this single 2.5" block replaces any factory block and eliminates the need for illegal block stacking. A professional alignment check is recommended after installation. Lifting the rear of your vehicle raises its center of gravity; exercise appropriate caution when towing or hauling.
Engineering Question: Are you adding rear lift to match a front leveling kit, restore towing rake, or both? Confirm your current front lift height and rear block configuration so we can verify the 26-21250 delivers the correct net rear lift for your application.
