I think your talking about the 1.5in 3 leaf add pack made by Deaver. We sell the same rear add leafs they work great if you pull out your overload leaf and run them with your other facotry leafs or if yo leave the overload in they still work pretty well, you just get more lift!lavaboy2 said:anyone running these? what was the actual lift. what model truck do you have? i have a 03 reg cab. 2.7. thanks in advance.
