Suspension Lift / Tire Help

So i'm looking at putting some bigger tires on my 1969 cj5. i was wondering what options i had to put 33" or possibly 35" tires on. i have read that a 4" lift will allow for both and that a 3" leaf spring lift will allow for 33". what is the a budget friendly way to get the lift i need to allow for these tire sizes. Thanks guys!

Let me be the first to offer ways NOT to do it...

I have had my '80 CJ7 about a month and love it, but know of at least one poor route when lifting, as installed by the PO to the PO, apparently.

First, lift shackles perhaps should be only so much. Mine are a full 3.5" longer than stock for about 1.5"-2.0" of lift, but I'm told may account for some of my ride issues and sway.

Second, you buy cheap springs and you get just that. I have a very stiff ride and little flex on about 4" lift there, and would do better with quality springs, maybe.

Also, I installed a pitman drop arm and made a huge difference. It is a must. Also I need a transfer case drop or double cardan driveshaft to fix vibrations... Vibrations made worse by the tires being a bit big for my gears... So need to regear the diffs.

Plainly put, there is no extremely cheap way to put 33s, much less 35s and do it RIGHT. I have very drivable, but not correct proof.

Do it right and you'll be happier. Lots of places sell whole kits with shocks, tcase drops, pitman arms, springs, shackles, whatever...

Of course we all have our own budgets, mine consisting of duct tape and bailing wire, and you can spend way to much if you want. To avoid spending more than necessary, do your homework and buy the right stuff for you the first time. Buying it the second time around will be a waste of money the first time.

OK, thanks for the input. I really do appreciate it. But by "budget friendly" i did not mean cheap. i mean which would be the most bang for my buck. i've looked and rancho and skyjacker kits but never put on a lift before so i don't know what it consists of. i mean with a 4" suspension will i have to extend anything or can i go half spring half body and get away with not lengthening anything. i'm just not sure on what "the right way" is. if that makes any sense at all

I am too knew to Jeep mods for my opinion to matter much. I have researched this subject extensively and just today put down a $500 deposit on the BDS 2.5" suspension lift kit, 33" BFG Mud T/A's, and 1.5" spacers. My 81 CJ is bone stock aside from a Motorcraft 2100 carb, DUI ignition, and short ram air intake I installed last year. I wanted to avoid some of the pitfalls I have heard by lifting too much. Jeep has been in the family since new and I don't want to screw it up. The 2.5" kit was where my search took me and BDS seems to make a very good one from all accounts.

thanks, and dont worry, i am newer than you. brought it home 3 days ago. just about to have it running adn new gas tank and seats. anyway.... so the 2.5" lift and 1.5" spacers give you enough room for 33" tires? and can anyone explain the "spacer" for me? sorry for being a super noobie

Just passing on what I have recently learned, but spacers will put wheels further from axle, mine are 1.5" wide, some are 1.25", etc... This will allow 33's to better fit without rubbing from what I was told. I think the wider, agressive stance will look nice as well.

ok, so i was reading around and thinking about a BDS lift. are you goin to have to lengthen anything with the 2.5" and spacers? because if not i may go that route but i really dont know what all is involved in making a 4" suspension lift fit right

I installed black diamond 3.5" lift springs with stronger, not longer, greasable shackles, stuffed 33's under it with only minor rubbing at full lock. I didn't need to lengthen anything except the brake lines.

And yes, don't forget the drop pitman arm. It's a must to avoid bump steer.

I have narrow axles, it's likely a backspace issue with the wheels. I got them off an '86.

ok. so if i went with say, a skyjacker 3.5-4" suspension lift and nitro shocks they run about 734$ plus pitman arm 100$. what all do i do other than the pitman arm? extend brake lines?

I installed a 4" Skyjacker lift and have 33's with no rubbing issues. Sometimes you will get rubbing if your rim offset isn't deep enough. In that case spacers can help.

To facilitate the lift, I added new Skyjacker shocks, dropped pitman arm, extended brake lines, CV rear driveshaft, and lowered the t-case a little over an inch with some home made steel shims. Nothing rubs and I have no vibrations.

And yes, there are 40 ways to skin this cat.
