I do not have a part number for the AAL. But you are an ontario guy right? Give on-all-4 a call (in Newmarket). Best prices around. Cost me $120 taxes in. Ask for Jim. (905) 895-0949

Mine is a ProComp, Long AAL

Just wondering if you could get a model number for your AAL after staring at my truck for the last 2 months with my leveling kit on, I now want to lift the rear back up a little. I am still undecided between the AAL and rear blocks. From what I can tell they are a bout the same price but the AAL gives you a little more payload but might ride a little rougher. Blocks keep the same ride and payload.

I do love the AAL. I got about 1.75" out of I when it was new, but it has since settled between 1.25 - 1.5". Not that bad. I got the Long Promcomp AAL, but I do not a part number. I got my stuff from a local shop near me in Newmarket Ontario Canada names On-All-4. Little hole in the wall shop, but has everything under the sun... and for prices better than anyone by at least 10%.

I've got a 1.5 AS level and I think I might even be a bit nose high, was thinking about blocks or AAL, you seem to be sold on the AAL. How much lift did you net and where did you get your kit?
