ReadyLIFT 1.5" Add-A-Leaf Rear Spring Kit | 2004–2014 Ford F-150

Is This for You?
You're running a 2004–2014 Ford F-150 and you need additional rear lift — whether to restore towing rake after a front leveling kit, increase rear load capacity, or stack rear lift with a set of ReadyLIFT rear blocks. The ReadyLIFT 26-2215 add-a-leaf inserts directly into your existing rear spring pack using the same heavy-duty steel construction as the factory rear springs — no blocks, no U-bolt changes required when used standalone. Works equally well paired with ReadyLIFT rear lift blocks for maximum rear lift height.

The Result
One pair of 1.5" heavy-duty steel add-a-leaf rear springs insert into the existing factory rear spring pack to deliver an additional 1.5" of rear lift. Same material and construction standard as the factory rear springs — not a lightweight stamped insert. Ideal for towing and hauling applications requiring additional rear lift and load support. Can be used standalone or combined with ReadyLIFT rear lift blocks for increased total rear lift height.

Verified Fitment (OFAS Standard)
✅ Fits: 2004–2014 Ford F-150 (2WD and 4WD)

Installation & Engineering Notes
Add-a-leaf springs insert into the existing factory rear spring pack — rear spring disassembly is required for installation. A professional installer is recommended. When used in combination with rear lift blocks, ensure U-bolts are the correct length for the combined block and spring pack height and torque all hardware to specification at ride height. Re-torque after the first 500 miles. Lifting the rear of your vehicle raises its center of gravity; exercise appropriate caution when towing or hauling.

Engineering Question: Are you using the 26-2215 add-a-leaf standalone or in combination with ReadyLIFT rear lift blocks? If combining, confirm your total desired rear lift height so we can verify the correct block and add-a-leaf combination for your application.
