Question What size lift to fit 35's with lots of room to flex

I need advice and some info i want to fit 35's on my jeep . the only thing is i dont know how much of a lift i need. i wanted to go soa , will soa and 2.5 leaf springs make the 35's fit nice and still have lots of room to flex? i seen a couple of jeeps with 4inch lift with 33 or 35s and they rub once they start flexing . i dont want any of that.I was thinking of going with skyjackers 2.5 double mitlary leaf spring wrap and soa. I currently have 1in body lift. Any help would be great.

Save your self a lot of head aches on the SOA lift. Get a regular lift 4" will do, plus your 1" body lift and then get some boomerang shackles with 1" lift, then set of TJ flares and cut the fenders a little.

This is about 10" of lift and 35's.



I don't know what "headaches" Jeepsr4me is talking about. SOA's are not that bad. It isn't as simple as fitting a lift kit but I don't recall any headaches. To do it properly requires a fair bit of cash, a weekend, the proper tools(welder, angle finder) and know-how. New stock springs on SOA will give you a comfortable ride and lots of lift. With 4" springs you have to get your fillings put back in your teeth every time you go for a ride.

I think you would be quite happy with this setup.

SOA with new stock springs, keep your body lift, and add 1" shackles. That will give you about 7" of lift.

Don't forget, with the 35s, you need to consider axles and gearing too.

with this kit i dont think i will be able to use boomerang shackles Skyjacker Rock Ready® Double Military Wrap 2.5" Leaf Springs for 87-95 Jeep® Wrangler YJ - Quadratec you know of any other shackles i can get? I defeinyly going to put new flares not sure from what brand or what jeep but i will look into it thanks Jeepsr4me , well I am pretty sure iam going soa i have a guy who can weld the perches for me , the rest i am going to do myslef and a couple of friends. Btw Coyote i love your jeep Cat i was looking at your photos and your flex looks great it doesnt even rub from what i saw. The only thing bothering me is where will i get a driveshaft from ? i dont plan to use the np231 ,going to switch it to a 300. and not sure off what axle is ideal for this setup with drivers side drop or passenger side drop but i think passenger drop is more cheaper so i dont have to do a flip kit to the dana 300 just get a clocking kit from advance. Any axles that would be good with this setup ? 2.5 spring lift ,Soa ,and 1inch body? i was thinking dana 44 front and back

Tom Woods can make anything you can dream up as far as drive shafts are concerned. That is where I got mine made.
Tom Wood's Custom Drive Shafts - Tom Woods Custom Drive Shafts Custom Driveshafts Specialist

You can use what ever axles you want. Dana 44's would be nice or Dana 44 front and Ford 8.8 rear.

Thanks I was wondering which dana 44 theres so many of them with different gears and different splines but i was thinking this for the front Vehicle: '71-80 Scout II rear, '74-80 front
Bolt pattern: 5 on 5.5", which allows wheel-swapping with any CJ if you need to borrow or lend a spare.
Width: 58" front, 58.25" or 58.5" rear -- 2-2.5" narrower than a YJ. That's not a big problem in the rear (other than off-camber stability), but it'll reduce turning radius up front. Less wheel backspacing compensates for this.
Brakes: 11" rear drums. What size front? Rear hard line junction is on opposite side of axle from YJ. Front brake line fitting is larger than YJ lines.
Spline count: 30
Caster: 0 degrees '71-79, 3 degrees in '80. A YJ wants about 7 degrees, so you'd have to rotate the knuckles on the axle tubes.
Other: Scout fronts have the diff very wide on the passenger side. This involves grinding to change the spring perch, and requires a t-case swap on YJ's. Tie rod mounting holes need to be redrilled closer to knuckles to regain a tight turning radius. Both rear axle shafts are the same length, necessitating only one spare, but the rear pinion is still offset 1.25" to the right, which is about 5/8" farther than the stock YJ. Going rate is around $100-200 for the rear. Lars swapped Scout D44's under his SOA YJ.


and if i wanted the ford 8.8 it has to be out of an explorer 95 and later with disc brakes? Do i have to match my gears for front and rear like the same number 4.01 front and 4.01 rear?

Yes, you need to match gears. Expensive things will break if you don't. I believe it is 96 and up for ones with disc brakes. Some 95's had them but not all. You only have to get those years if you want disc brakes. If you want drums you can get the older ones, though I don't know why you would do that.

Bad pic but you get the idea. This my rig with 4.5" RE leafs SOA, 35's on the rear and pizza cutters up front. Also a ratchet strap holding up the trans. I started building before I started thinking. I'm wanting to go back to spring under just so I can drive it on the road.

2.5" old man emu springs with a SOA and a 1" body lift. Thats what I am going to do after the 4" lift springs I have are worn out.
Much better flex than lift springs.
This winter I plan on getting revolver shackles and longer shocks, to help with more flex.
Big improvement is to ditch the sway bar and track bars.

Funny you named off some of the "headaches". With a bolt on kit you avoid the welder and new drive shafts, and the steering issues, to be done right takes more than slapping the pads on top of axles.

What does your steering look like?

Oh, I'm a mechanic by trade so I didn't consider those as headaches. It was just a walk in the park for me. To me a headache is when you can't find the right parts for the job or the parts are not lining up or not fitting correctly. I can see how someone could think that if you don't have a fairly good understanding of how everything is assembled and works together.
He does have a friend that can do the welding for him so that bit isn't a worry.

My steering looks great. I can't post pictures from my work computer but when I get home I'll post some up.

I try to put myself in the shoes of the person asking. You ever heard the saying" If you gotta ask then...". I have to assume if they asking about it then they dont know what they are really getting into. To some a engine and trans tear down and rebuild is impossible. But to me, you can take it all apart and stick in a barrel and I will get it back together. I am coming up with design drawings to use JK axles and the stock links to be put under a YJ. A bolt on deal for the most part.

I Really I want to see a picture of your steering.

Thanks. A lot of people for get about steering, See you raised yours... Make it yourself or you get that kit?

Also like what you did with the brake lines.... See little things what other people going to have to realize needs to be done.

You also got a SYE, can't tell if you got a 35 in there?

The steering bracket is from JB4x4.com. And I made the drag link. The brake lines didn't need an extension since I relocated them. Rubicon Express SYE and a Tom Woods CV shaft. The rear axle is a Ford 8.8.

Honestly other than climbing into my jeep it drives and rides on the highway almost like a stock jeep.

I didn't go over all the little things because when most people come in asking if they should do an SOA or not they make up their mind and then start researching and asking about all the details like brake lines, sye, and steering.

also i might stick with my np231 and put in the sye ,with toms driveshaft. Some people where telling me to drop the skid plate 1 nich , and some others where telling me to drop the whole drivetrain alltogeher to improve the driveshaft angle. Umm the brake lines i didnt really worry much i read about relocating them , so i will proably do that or get some braidless steel from quadratec.hmm for the steering am totally lost all i know i need a dropped pitman arm from a zj if i remember or just order one that is dropped

With that kind of lift your going to need more than just a dropped pitman arm. When I did mine the drag link would hit the spring and prevent it from going to full lock. I had lost about 1/3rd of the turning ability in that direction.

I bought a steering bracket from these guys and it pretty much put all my steering geometry back to stock.

See the headaches now?
There are rewards for doing the SOA, but for most the SUA lift is by far easier.
If we can get out all the little odds and ends that needs to be done I feel most will say its not worth the trouble.And to the others that will read this, they will see what it takes and will have a better understanding of whats involved.

I'm still not convinced that was a headache. I would say it was more of a hiccup. As I was lifting it even more I could already see that the steering was going to have to be modified and I had done the parts research before beginning the project so I already knew what had to be done. I'm just being difficult aren't I.

3.50 gears aren't going to be too bad. That is of course if you plan on driving it on the highway. I'm running 3.73 gears. If not I would go 4.10 or numerically higher.

I can't remember which length of shocks I ordered but I got them from Summit Racing. What I did was, after the install I took the jeep out and flexed it so it was at it's max and min. Then I measured to see what the lengths were and ordered shocks to match.

You'll need a high steer kit. If you go with 6 inch lift or bigger. It will help with the sloppy steering. I just went through all that stuff when I put a 6" suspension lift and 1.5 inch shackles. the high steer helped out big time!
