CJ lifting unknowns

I am about to embark on a 4inch lift journey into the unknown on my 83 CJ7. Lift is a Pro comp system with shocks, shims, pitman arm and of course springs with ubolts. I also picked up brake line extensions. My question to you is what else am I going to encounter that I need to know before I get started? I want everything I need before loosening a single bolt. With all the experts out there surely every aspect of lifting a jeep has been uncovered. Thanks for the help.

Re: CJ lifting unknowns

Spray every bolt on the Jeep a few days before you start with the kit with some good penetrating oil, and keep spraying them. Old Jeep don't like letting go of their stock parts very well. If you are going to lower the tcase expect a few of the bolt to break, or the nut welding inside the frame to come loose. This is a MAJOR PAIN IN THE ARSE. The rest of the kit is pretty much fool proof.

Re: CJ lifting unknowns

The only other thing missing from your list is spring bushings. Beware of the Pro Comp (aka Pro Crap) kits though. Take this with a grain of salt, but they have a bad reputation of a very rough ride.

Re: CJ lifting unknowns

Would you be suggesting I use a different system all together? I only went with the Pro Comp because of the completeness and cost of the system over the others that I looked at. Of course, I also don't want to wear a kidney belt while operating my jeep either. What would you suggest for 4inch lift with a decent ride?

Re: CJ lifting unknowns

I had the procomp 2.5" lift and i gotta admit that it pretty much sucked. I got a lot of ride height out of it but the springs were hard as rocks. If you're using the Procomp kit, get SOFT shocks! I used rancho 5000s which are kinda of hard. Also, watch for "fanning" of the springs. My rear springs fanned out and I had to clamp them back together...very annoying.

Re: CJ lifting unknowns

The one thing you will probably find most difficult it getting that old pitman off. Be careful, sometimes a bfh is not the way to go. Also, it has been said that the Pro-Comp springs are stiff, and yes they are, but what you need to if you still plan on going with them is to wheel the snot out of them for about 6 months, then they start working real well, and won't sag like some others. But, the ride will still be stiff, the articulation will be good though.

Re: CJ lifting unknowns

The rubicon express Extreme Duty kit's are as complete as they come and include springs, 2.5" wide fornt springs (same as a yj, better ride and flex) and all the parts to do the swap, greasable shackles and bushings, pitman arm, brake lines, drop pitman arm, shocks, sway bar dsicos (though thiers kinda suck), u-bolts, t-case drop and maybe some other stuff i can't remember. Super lift kits are also well liked for the most part. You will need brake fluid, and flare nut wrenches to do your brake lines, a pitman arm puller, lots of penetrating oil, maybe something to cut old bolts out with, basic hand tools, jack stand, and a helper helps.

Re: CJ lifting unknowns

I stand behind CJJC,
I, too, havea procomp lift, and while it may be a stiff kit, it flexes better and better everytime I use it, and because it is so stiff, it doesnt tend to sag like other softer kits that offer immediate articulation out of the box.
Just give it time.

Re: CJ lifting unknowns

Dont listen to these guys trying to make themselves feel better about buying a pro comp(no offense to anyone, just trying to make a point). If you can return the lift, by all means, do it! If not be prepared for a very rough ride for a while, but it probably wont sage like some others.
If you can return it try to get a rubicon express, super lift, rancho or skyjacker(shyjackers tend to sag after awhile). I am a big rancho fan, I think their systems are well built and well thought out(Try desert rat, they have good prices and give you they shocks with the kit).

You shouldn't have any promblems installing that kit, you can do it in an afternoon. get an impact wrench for the U bolts with and deep well sockets.
one mistake I have made in the past is not to trim my Ubolts after an install, then going out and bending them all over on a rock. trim them or get u bolt skid plates.
good luck

Re: CJ lifting unknowns

Does Rubicon Express make a system for CJ's? Does Rancho even make a 4" lift for CJ's? Is a transfer case lowering kit required with a 4" lift? Sorry for my ignorance, inquiring minds want to know hehe.
