ReadyLIFT 2.0" OEM-Style Cast Iron Rear Block Kit | 2003–2013 Ram 2500 4WD & 2003–2025 Ram 3500 4WD SRW without Overload Springs
⚠️ Single Rear Wheel (SRW) only. Non-Camper Package trucks only. For use on trucks WITHOUT top-mounted overload springs.
Is This for You?
You're running a 2003–2013 Ram 2500 4WD or a 2003–2025 Ram 3500 4WD — single rear wheel, no camper package, no top-mounted overload springs — and you need 2" of rear lift to match a front leveling kit, restore towing rake, or increase rear load capacity. Stacking blocks is dangerous and illegal in some states. The ReadyLIFT 66-1202 is the engineered solution — OEM-style cast iron construction, never made from lightweight extrusions, with E-coated U-bolts and all necessary hardware.
The Result
Two OEM-style cast iron 2.0" rear lift blocks with E-coated U-bolts, eight nuts, and eight washers deliver 2.0" of rear lift on qualifying Ram 2500 and Ram 3500 4WD SRW applications. Cast iron construction matches the OEM block material standard for maximum strength and durability. Eliminates the need for dangerous and potentially illegal block stacking.

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" block replaces any factory block. 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: Is your Ram 2500 or Ram 3500 a Single Rear Wheel (SRW) truck without the Camper Package and without top-mounted overload springs? Note that Ram 2500 fitment for this kit ends at 2013 — 2014 and newer Ram 2500 trucks are not compatible. Confirm your model year, axle configuration, and spring pack configuration before ordering.
