I.F.S. Tech Sheet for Vehicles with coil spring pockets stamped into the frame

Set the vehicle up at the desired ride height. Since this is a custom built kit for your vehicle, we try to build it to your desired ride height. Just tell us where the center hub of the wheel needs to be in relation to the frame rail (1" above the bottom, 2" below, etc.).

Include a template of the side of the frame rail and the top lip, with the axle centerline marked perpendicular to the ground. This needs to be done with the vehicle at the desired ride height. This template should be start at the front tip of the frame to the point near the firewall where you will install the new rails.

Include a measurement on how far forward the core support crossmember is from axle centerline and how far down it is below the bottom of the frame rails.

Measure the overall width of the fenders from the inside lip to inside lip. This can be done with a plumb bob to the ground, from one side to the other.
