i have a 76 hiboy to . it doesnt have any lift and i have 35s on it but it looks like i could clear 38s if i wanted so unless you have 38s or bigger you really dont need a lift on a hiboy unless you just like the looks.
Yea you have the 6 pk front leafs right? It all depends on how tired the springs are, I have seen wore our HB front springs that were almost flat....
The OP asked about where to look for a lift kit, what brand is the best, and how difficult it is to install. I gave him some direction on the lifts ect, but kept my opinion to myself on the best brand.
He did not ask what size tires he could run with out a lift or what size lift he need to run X size tires.....but I am sure its coming here shortly.
