i got a 1983 f150 stepside. i need to know what size lift (or combination of lifting methods like suspension lift and blocks) you need to fit 39.5" tires, and where i could buy it.

 

I dont really know too much about the older f150s but your best bet is to just contact the closest offroad/custom car or truck shop and ask them. Depending on where you're located I get all my stuff from Down East Offroad in Wilson, NC. They have an online website you can order lots of stuff from too and prices aren't bad. www.downeastoffroad.com and if you do decide to get something from them, tell them Adam H. referred you so I can get free stuff, lol

 

If you are runnig the stock ttb set up your gonna break alot of axle parts. Your gonna need at least a 8inch kit with a 3inch body lift and some fender trimming. The truck in my avatar has 39 swampers with a solid axle swap im running almost 14 inches in the front with 12 in the back and i still need to install my body lift . National tire and wheel is a good place to start looking for kits . Expect to spend around 1500 to get her up that high
