Hey just a quick question. I want to lift my 94 s-cab f150. I was wondering how hard its to install a split front axle onto a 4x2. Is it worth it or should I just lift it and put a limited slip in rear?

 

Is your truck a 2wd?
Find a suspension system and do the whole suspension lift, and a L/S rear end sounds good.
Skyjacker has 4inch 2wd suspension systems also check Ebay for deals.
A locker may also work in the rear diff, if you go to larger tires, you should consider regearing too.
