I want to use add a leaf instead of blocks to lift my truck in the rear. Might as well get some lift and more load capacity! Anyways, I`m not exactly sure how they work.. how much lift will one leaf on each side give me? Do u just slap another leaf on top of all the other ones? The more info you guys give me the better!
Thanks alot

 

The AAL goes on the bottom of the leaf pack. It is very easy to do. Unbolt the U-Bolts, Unbolt the center pin (Use a C-Clamp to hold the pressure). Then install the new leaf spring and the new center pin. Re-install everything.

When you look up AAL the ad should say how much it will lift it. 2in or so, 1,000lbs extra carrying capacity or so. www.summitracing.com or www.jcw.com has good prices.
