Hmmm....Sorry I cant say anything good about Downey.
I bought the Taco AAL's from them last April for my 99 daily driver. 8 months later, one of the AAL's broke off in the middle, and Downey absolutely refuses to warranty it. Its only a $31.25 part!!
Be aware (supposedly) they only have a 90 day warranty on springs.
I only put the AAL's in, not because I wanted lift, but it seemed the cheapest way to get the truck sitting back at stock height, since the stock leafs had gone negative real bad.
Even with the AAL's in, they settled to where I only had about an inch over stock, and I can see that the Taco springs are starting to bend around the ends of the AAL.
Sounds like you got the early 95-97 2 leaf packs. I have the later 3 leaf packs, and THEY suck bad! I think you'll need to add at least 2, maybe even 3 leaves.
It might be cheaper and better if you were to think about doing the Chevy swap....
