I have a 74 jeep j20 and im wanting to put a 6 inch lift so i can clear 35's i was going to do a 6 inch suspension but then i have to have custom drive shafts made and they are about $400 each so my thought was a 3 inch suspension and a 3 inch body lift what are yalls thoughts

Not seeing why you would need custom driveshafts???...
My brother has a 77 j-10 with a 6" lift and had no problems running the stock shafts. His is a shortbox too so your longer wheelbase will be fine on the rear driveshaft. The front shaft may be questionable since it will have a bit of an angle on it, but the cardan joint that they used should handle it unless hardcore off-roading is in your plans and you intend to droop the suspension a lot.

Ahh, i can tell you the rear will be fine. You'll just have to try the front out. You could unhook it from the pinion flange, measure 6-7" straight down and see how it does.
6" is what i'd like to do on mine some day. I may go with the spring over setup but still undecided. Edited by jeepjerry - Jun/06/2011 at 11:00pm |

i looked into the spring over conversion but it is really expensive because on top of all the stuff you have to buy that is originally on the bottom to put on top of the axle you have to buy a $300steering knuckle or thats what i would do

I did my Wagoneer with a 3" lift and a 3" Body lift. The body lift was actually nice when I had to get under the truck and work on stuff (especially tranny or t-case stuff) because it gives you 3" of more space around everything. That was nice but installing the the body lift was a PITA. Most of the captured body nuts would brake loose and spins as you were trying to remove the body bolts. Trying to get in there and keep the nuts from spinning while trying to remove the rusty, corroded body bolts isn't fun. Then you'll need to be able to lift the body up. A wagon is a challenge the lift off the frame but a J-truck will be easier. The linkage for my transmission shifter had to be lengthened as well, I had to adjust my flag shifter in the floor, and the radiator shroud has to be dropped 3". It's alot of work to put a body lift on. Your's being a '74 J-truck will have less to modify especially if it's a manual tranny. I would just by the 6" lift and be done. The rear shaft will bolt up no problem. Other folks have been able to bolt there front shaft up. It's just one of those things you'll just have to try. Paying to have parts modified on a lifted truck is just part of the game. Good Luck.

Why not run a 3 or 4 inch lift? Remember you'll get some lift from the tires. A lot of guys 'overbuild' rigs these days, and it's really amazing what kind of crap my XJ Cherokee can go through with a 3" lift, and 31" BFG all terrains. My only issue with it is that it has an open diff out back after I found that one of the universal joint 'ears' on the dana 35 yoke broke off- so I traded it to a buddy and bought a 8.25. Sadly it's a peg leg.

Yeah, don't cut the fenders. As long as you have some help, put a body lift on it. I read a thread on the IFSJA Forum that the trucks that old have a different and simpler body mount design than the later model FSJ's so it will probably be an easy job. You will like the body lift if you ever have to work on anything underneath the truck.
