Add-A-Leaf....You put it in your stock leaf pack and it increases the spring rate and gives you lift. Sorta like an additional over-load spring. A relatively cheap way to get rear lift without replacing the entire leaf pack or going with lift shackles.
when i plugged in your part number into skyjackers website, it says its for a 97 sr5, i know after 96 the leafs changed, im gonna figure out if these will fit tomorrow for sure, and then they are def sold.
They definately fit up to 2004 Tacos. Skyjacker doesn't do a very good job of updating/changing their part number-to-vehicle references. I looked the part number up in the Skyjacker book at the local distributors place.
