I had a procomp 4" lift on my 89 taco. Worked great. I got some air a few times, and nothing happened to it. I had it for about 5 yrs and I had no problem. Others might agree, and others might not. I got that from 4wheelparts.com I think they have other kits too...At that time, the lift cost me around 680 bucks. I did the install myself in a little under two days. Not too dificult.
