This block kit features 4.0" fabricated steel Flat Rear Blocks, billet drive line spacer, E-coated U-bolts and nuts & washers. The manufacturing of these rear blocks is based on the factory block design and features integrated OEM style bump stops.

This block kit is the perfect Tow Package upgrade for stock height and lifted or leveled trucks and includes a Limited Lifetime Warranty. 

Not for use on 2019-Up F-350.

Lift height will vary depending on what factory block your truck has.

This block kit is for use on 2017-2023 Ford F250 4WD & 2017-2018 Ford F-350 4WD trucks with 2-piece drive shaft. 

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.
