Fitted Leaf Springs are designed by Skyjacker for specific spring applications. If you are installing Skyjacker lifted springs and you plan to haul extra toys and accessories on a regular basis, then we highly recommend adding a fitted leaf. Adding a fitted leaf will turn a regular lifted spring pack into a heavy duty lifted spring pack.
The fitted leaf will strengthen the load carrying capacity of the leaf pack, but is NOT designed to give additional lift. However, if you have a constant load on your lifted Skyjacker spings, and you later add this fitted leaf, it will help lift the spring back to its original position.
These fitted leafs are unique to Skyjacker. They are specially designed to work with a specific spring and for a specific vehicle. The picture below shows a rear Scout II 4inch lifted Skyjacker Softride Spring and a skyjacker fitted leaf that was designed for this spring. You can see the arch of the fitted leaf is nearly identical to the arch of the pack.
The fitted spring is installed into your spring pack in order of spring length. As you can see from the photo below, ths particular fitted leaf would be inserted in the third spring position. You always want the shortest leaf on the bottom and the springs to get progressively longer as you work your way up the pack.
Please note that fitted leaf springs are built by Skyjacker as they are ordered. They are NOT a stock item and may take a couple extra weeks to deliver. If you are towing, hauling or using heavy accessories such as a winch, it is well worth the wait.
