im looking a a 4-5" lift kit for the front a my ifs 86 toyota pickup 4x4. What or where can you get a lift for the back? which is better blocks,custom springs, what else is there?

thats a good question but sorry i have no idea.

auto zone, checkers, and napa have an adapter for your leaf springs that you can get, very inexpensive. You have the option of 1" 2" or 3" lift, I have it for mine just haven't put it on yet. I believe that it is universal as well, also when I went in to get it they didn't know what I was talking about but they had it. Can't remember what it is called but if I can remember I will let ya know

If you have the money, I would go with custom leaf packs. Shackles and add-a-leafs will work too, but I don't think they make them with the amount of lift you want. Maybe you could combine the shakles with the AALs?
