We like to use the main leaf from the front of a six-cylinder YJ to augment our stock YJ leaf packs. We use the six-cylinder main leaf because it has a higher spring rate than the four-cylinder leaf. Simply cut the eyes off the main leaf right where it starts curving and add it to your pack for 1-2 inches of lift and added antiwrap protection. Shown here is an exploded view of a YJ pack with the added leaf. For a slightly-stiffer ride but with 2-3 inches of lift, front '80s-era Wagoneer springs work well. However, if you use the entire pack, it will move your axle about 2 inches due to the offset centerpin.
