Product Description

This is a kit that will add 6 inch's of lift over your springs size, so 12" springs nets 18" lift. Current kit can be positioned to almost any height up to 6 inch by moving rear shackle hangers up the frame and re drilling front spring eye. 3/4 and 1 ton frames will require minor trimming of front hanger due to frame cross member that is not removable like a 1/2 ton. Below are a few shots of the process. Also check the picture section for more info on installation. 

Uses Chevy 4x4 lift 73-87 era front springs 47 inch. 

Front and rear hangers can be pushed(moved) forward and back to stretch spring length needed to run 52 inch rear springs. Apr 2" ea direction. The rear spring bushings are not as wide as the front spring bushings so a 3/8" per side spacer is used when rear up front is done.

Kit is bolt on for positioning is desired, final install will require full welding.

Kit is based on 73-87 Chevy front 47 inch leaf springs with a 3 3/4 wide over all width. Some aftermarket springs are narrower and will require a spacer of some variety to make fit correctly. If you are interested in using the 52 inch Chevy rear springs, you will simply lengthen the hangers front to rear to fit them. These springs will require a 3/8ths shim per side to fit correctly in our hangers as they are only 3" wide.

Do to the hangers being weld on you can use them on either a 2wd or 4 wd 88-08 pickup.
