Ok so this is going to be a long post.. the jist.. how do you tell what size lift leafs you have???? so now the easy question is out... the long post back in 1997 I had a guy lift my truck.. so it would pass nj strict lift laws (and I had a dirt driveway and not the tools like I do now ) so he put 12" rear leafs on the truck and 13" fronts I already had a 3" body lift was going with rockwells and 53" michelins.... well nj changed their lift laws so I had to bring the truck down... it sat for 7 years..then viola end of 2004 on the road.... I went from this (without body lift) just realized the rear block is already removed from the drivers side.. and pass side is up in the air via hilift jack... this will give you an idea of how high the back was... to this now here is what I did... I took the 13" front leafs off.... put superlift softride front 6" leafs removed the factory tapered block from the back the block is like 2.5" on one side and 2.75" on the other.... howevever if you look at the pics.. I supposedly still have the 12" rear leafs on the truck... how can I tell if they are really 12's or if it was 12" with my stock block equaling say 10" leafs plus my block????? that would mean remove block and it is like close to 9" rear.... any help... just curious... a bud was over and I told him my rear 12" leafs were still on the truck.. and we were looking and the math isnt adding up anymore???????
