Two, Four, Six, Eight Inch Super Duty Lift Kits

Four Inches

Let’s go a little higher, shall we? This is the 4-inch system, front leaf springs included but not shown. Note the front urethane bumpstops, rear lift blocks, track bar drop bracket, and dropped pitman arm. The stock sway bar end links are relocated to compensate for the lift.

The 4-, 6-, and 8-inch lift systems all use a dropped pitman arm, but it’s the same part for each kit. As such, A.J. only had to swap the pitman arm once.

At four inches of lift, the truck looks even more aggressive. If a front leveling kit looks too tame, go for the 4-inch kit.

The 6-inch kit goes taller in the front via leaf packs and uses a combination of lift blocks and add-a-leafs for rear height. The track bar drop bracket now features side-to-side adjustment. With the 4- and 6-inch lift kits, stock brake lines are retained but the brake line mounting brackets are replaced to allow the stock lines to reach the new lift heights. New sway bar end links are included.

The 6-inch kit clears 35s easily (and you can clear 35s with the leveling kit and with the 4-inch kit) so we wanted to see what the 6-inch kit would look like with 37s. Here it is. Trouble is, there’s some rubbing goin’ on up front. If you want to run a 6-inch kit and 37s, you’ll have to do some custom trimming and fit-checking.

Here’s the 6-inch kit on 35s.

The 8-inch kit is a whole new realm, as it includes new rear leaf packs (no blocks, no add-a-leafs) and a new front driveshaft to span the extra distance. Also seen are Tuff Country’s dual steering stabilizer kit and front triple shock kit. New sway bar end links and extended brake lines are part of the Tuff Country 8-inch lift system.

The 8-inch system looks great with 37s and considering the big dimensions of the Super Duty, the whole package doesn’t look disproportionate.

The corners of the front bumper’s lower plastic valance needed some slight trimming.
