Another SOA Question? (1 Viewer)

[wtmtnterror]

I'm working on getting my 74 up in the air a little more. Just want to know if anyone out there has done a spring over with a virgin tub?

I don't have any pics to show yet, working on the rear axle now. So what size of tire would I be able to run with this done? I know that there are many variables here, I'm just looking for some examples.

I don't know if I want to cut the tub just yet.

I'm also running 2.5" lift springs minus one leaf spring.

if you've got saggy old factory springs, then you'll be fine with 35's. That's the way I'm setup currently and it works great. Good luck!

Better keep the tires skinny...

What size tires are you planning

 

[Adventure Teq]

Ran SOA with stock springs and 35s no prob. No cutting, no rubbing.

Run a search , what are ya new?

Here's a pic I saved of someone who went SOA with 2 1/2" springs. I think they're 38s. A bit much IMO when others have made good with different setups. Poser for example.

that 40 is huge!

I'm running 39.5x18 boggers with FJ55 springs (no lift added) and a 3 inch body lift. Uncut tub. A buddy runs the same tires with no body lift and trimmed rear fenders. Another runs 39.5x15 TSLs with a one inch body lift untrimmed tub and stock springs. Yet another runs 38x15 TSLs with no body lift and stock springs as well (can't remember right now if his rear fenders are trimmed or not...).


These are just the "bigger" rigs. We have several running 36s and 35s.

No of us have rub problems.

And none of us are poseurs.

I'm running 34x10.50 ltbs on a 15x8 right now.....

Thanks for the pic Hawk, I have seen that one before and it is huge!

I was thinking like a 37x12.50ish but 38s would be good too

how about some more pics here guys. Ok I'm not a purist by any means,

maybe time to break out the sawzall...

Ok any info on this pic? Kind of what I'm looking for.

Pretty sure that's a picture of a SUA rig.

Well i got a 77 and my tub is trim i got the stock springs i could run 35s easily .and i could run 37s but they could be only like 37 by 12 s. if i was you i would use the stock springs casue the old springs got more flexs and do a spring flip and make your wheelbase long

I've got 33's right now but my tup is trimmed somewhat. BUt I also have a ton of room for bigger tires.

35's are about as big as you really want to go with a stock drivetrain. You will run into issues if you go biggers unless you drive like my grandmother.

 

[bustanutley]

that pic you posted is definitely SUA

This is just after I did the SOA with stock springs in their stock locations. Those are 36x14.50's. When flexed, the rear tires would hit the front of the wheel opening. I've since flipped the rear springs and cut the tub to use TJ flares.

heres mine ,body tub trimmed , stock springs , extra stock leaf added to all 4 packs , 38.5 swamps ,and a 3 inch body , i know everybody hates body lifts but it works for me , did not flip rear springs , just drilled a new hole in the spring perch and move axle back 1 1/2 inches , for the front ,shackle reversal , flipped springs , new hole drilled in perch to move axle back a inch or so to stop the tire from wacking my fender and stock length shackles

 

[thsorens]

Heres mine, SOA with stock springs and 35's with 10" rims. PLENTY OF ROOM! I will probably go with 37's next time. Actually, I'd like to lower this thing down a little. I might take a leaf out of each pack all the way around......

35's are about as big as you really want to go with a stock drivetrain. You will run into issues if you go biggers unless you drive like my grandmother.

My experience says otherwise. I *have* gone to Rocks under one of my rigs,but it's a bit...radical... When you get to the 40 inch range the drivetrain is reaching it's limits. But 35s? Naw, 36s and 38s are fine on a stock drivetrain. Me and the folks I wheel with run a lot of tires in this range and have for a long time.

Like I've said before. You can break ANYTHING if you try hard enough.

That rig is SUA. It was the shop truck at Cruiser Solutions in NH for many years before being sold. The "diamond plate" is a first gen. aluminum tub with diamond sides instead of smooth sides. Have a look here for more details...
http://www.cruisersolutions.com/forsale.htm The truck is about 2/3 down the page with details on the main parts of the suspension used.

HTH,

Diamond plating is PITA if it stays...if i ever bought a rig the diamond plate would be the FIRST thing to go!

Wheeling maybe. Low range going up a steep incline where speed is not your friend with 38's and 4.11's is going to make things mighty tough on a clutch.

Driving around town may be okay but around here with all the hills and mountains your going to be changing gears every 5 seconds. 38 s and stock course splined birf is just asking for trouble.
