Increase Forward Rake on your Super Duty for Improved Towing and Hauling

Even the powerful 2017-2022 F250 & F350 trucks can suffer from rear squat under extremely heavy loads, which can make their handling characteristics subpar when you're hauling around your gear, toys, or whatever else you have in mind. The good news is that ReadyLift's 4" rear block kit is here to give your Super Duty truck the extra rake it needs to haul and tow just about anything without ever having to suffer from rear rake or squat under load. ReadyLift's 4" Rear Block Kit is a drop-in replacement for your Super Duty's stock rear block and come with both new U-bolts and nuts to give you and your truck everything you need to tow and haul that much better.

Cast Iron Rear Blocks with OE-Style Design for Fitment and Function

While most rear block kits are just hunks of metal with some U-bolts, ReadyLift's 4" Rear Block Kit was carefully designed to give your truck some extra rear lift while fitting perfectly and eliminating some of the issues caused by lesser-quality aftermarket rear block kits. Each of ReadyLift's blocks are made from heavy-duty cast iron with an E-coat finish to prevent corrosion. The blocks feature OE-style cast-in center pins and are slightly tapered to provide OE fitment and near-OE driveline function so you don't have to worry about safety or reliability issues down the road. The blocks have bump stop landings and come with a full set of e-coated u-bolts, as well as new U-bolt nuts and washers.

Driveshaft Fitment: this rear block kit was only designed to fit Super Dutys with two-piece driveshafts out of the box. Super Dutys with one-piece driveshafts will require purchasing this kit that we have available.

Note for Air Spring/Load Leveling Systems: The lift blocks in this kit are not designed to work with aftermarket or factory add-on air spring/load leveling kits that attach to the bump stop tangs. Use of this type of air bag system will void all block warranties and can cause failure of the block bump stop tang.
