Guys..
I want to put the widest (best) axles that will fit under my stock CJ5. I want to also do a SOA upgrade, running the stock Spring setup. I have limited welding experience, and realize that spring perches will need to be moved and welded to accommodate the wider axles.
My question is, what are the widest axles, and easiest to put in my jeep, and which vehicle to go look for in the salvage yard to get them from? Currently running 31x10.50 15's.. Plan on running no taller than 35's. The jeep will be running through fairly level mud flats, and the occasional sand dune's. Thanks in advance.

You could get a kit to install full width axles on your CJ.
Poly Performance JEEP/TRUCK & BUGGY*::*Suspension*::*Suspension & Lift Kits*::*Jeep Suspension Systems*::*1976-1986 Jeep CJ Suspesnion Systems*::*Poison Spyder Customs*::*Poison Spyder Jeep CJ Full Width Axle Conversion Kit - 4X4 Off-Road Parts, JK S


SOA gives you 6 inches of lift. That's a lot of height. Getting full width axles would help regain the stability.
Most of the tires would then be outside the fenders so check local laws before you start this project.

Thanks for the link.. That looks like it would be fairly easy to install, and then just bolt up some axles. Gonna have to go cruising the salvage yards for axles that fit the dimensions from the website. Thanks bro!!

early ( 70's to early 80's) chevy and dodge will both have pass. side pumpkins and the spring perches will be for SOA. Look for one with high steer knuckles.

Thanks Old Dog.
How much wider would those axles be.. Looking to get the tires as far outside the fenders as I can possibly go.. My goal for this particular Jeep is to sling as much mud as one possibly can, with a jeep. I wanna get mudday! LOL.

I have heard of some people having trouble getting Poison Spider kits in a timely fashion.

Would these work in my jeep, with minimal modifications?
Chevy axles

I would pass on ton axles.....you're talking about a corp 10bolt front and either a 12bolt rear or a D44. These are not much of an upgrade over the stock axles (although the 10b is around the strength of a 44)

Swapping axles is never easy or cheap. Do it right the first time:::

I wouldnt look for anything smaller then 3/4 ton running gear if you are planning on slinging mud everywhere....better would be 1 ton running gear (D60/D60-D60/14b)

Another thing you will find out is running 35's on full width axles creates a huge clearance problem

Thanks for the advice. I currently have a brand new set of 31's.. The 35's were more of an option when the 31's go bad. Maybe go 33's or another set of 31's.. But at the rate at which i run my jeep..That will take forever. (Never home due to work)..Currently down in brazil. :-/

Yes
IMHO I don't think you would have any problem going to 35 inch tires but at that time you would want to install 4.88 gears. 3.73 gears should work fine for 31 or 33 inch tires.
