PROJECT OBSESSED

The intercooler specific kit simply has the cross bar lower to accommodate an intercooler. Otherwise the non intercooled version tucks it up behind the bumper for a cleaner look. If you have a diesel we recommend doing the intercooled version even if you don't have an intercooler just the option is always there.

Installation Notes:

Sway bar will need to be deleted, or will need end links extended. Our 3" Sway bar end link extensions are available here: 85-97 F-350 Sway Bar End Link Extensions

We have had a few customers with worn out spring bushings and sliders have issues with clearing the shackles on the 2" FSR kits with the military wrap. You need quality to spec parts to make this work.

Instructions for Replacing Leaf Spring Bushings and Isolators

It is common for the front frame horns to be spread due to age as the only thing holding the front of the frame together is the rivets at the engine cross member. You may need to pull the frame together to get the hanger on.

These trucks were not built to a high level of precision. Some of the rivet holes may need to be opened up with a die grinder as the holes may not line up perfectly.

When installing this kit with lift springs, the springs are often shorter than stock as they are re-arched stock springs to get more lift. We recommend drilling just one hole for the spring hanger and holding it in place with one bolt until you are able to set it down and check to see that the shackle angle is satisfactory. Then drill the remaining holes.
