How to Install a Body Lift Kit on a Truck

The first step in every installation is verifying you have everything to do the installation. Verify that all the nuts, bolts, brackets, and hardware are included, and gather the tools you will need. Don’t get worried if you have extra hardware, as most manufacturers include hardware for every application. You’ll just have to figure out which works for your specific application.

This installation was on a 07’ Dodge Ram Quad Cab 4 x 2. The exact steps for your application may vary slightly but the overall process will be the same for any body lift. I will warn you from the very beginning that this is not a mod that is for the faint of heart. If the sound of a metal cutting blade shaving off pieces of your front bumper makes your stomach turn, perhaps professional installation would be a good investment. Most manufacturers supply detailed and very well written instructions complete with pictures and arrows for the do-it-yourself crowd.

Disconnect the battery cables and remove the airbag fuse. Measure and record distances between the front bumper and fenders, rear bumper and bed, and bed and cab on both sides. Record these measurements in the instructions.

Underneath the vehicle, there are several lines, straps, and clips that have to be removed or disconnected. Be sure to refer to special instructions for both automatic and manual transmissions.

Loosen all cab bolts and remove from passenger side only. Use a hydraulic jack and block of wood to lift the passenger side, install the kit blocks and kit bolts but do not tighten. Move everything around and do the same thing on the driver’s side.

The same process is used to lift the bed.

Set the bed to cab spacing from the recorded measurements and check alignment of cab and bed, by sighting down the side of truck from all angles. Make any necessary adjustments, remove each new spacer bolt, apply Loctite and tighten to 55 ft. lbs.

Now it’s just a matter of doing the morning’s work in reverse.

There are a few mods that have to be made. But a quality kit should include the brackets and picture instructions to complete these modifications.

Modify the spare tire wench. Some drilling is required during this step.

install brackets

Reinstall the rear bumper with the brackets provided and align the rear bumper to the bed according to the measurements you recorded earlier. Most kits include the brackets to lift both bumpers so there is no gap between the body and the bumpers.

The replacement front bumper brackets do require 2 new notches into the front bumper, and a bit of trimming on the frame horns and crush zones. We used a reciprocating saw with a metal cutting blade and were pleased with the results.
