Default Axle option for this winters project

I have currently under my cj7 a c20 4.10's and d30 4.10's locked. I am running a healthy 360 and 35's. I already own a set (front and rear) of scout II d44's and a 28 spline ford 9" from an early bronco and an 86 cj d44.

I want to regear to 4.56 and want to lock both axles. I am considering spring over but haven't decided on that yet.

Which combination of axles that I own would be a good choice? Or should I just broom everything I own and go with d60's? I want to stay around 60" wms to wms.

You wanna stay with 35s for a while or go bigger?

Will probably stay with the 35's for right now. But I would like the option in the future of going bigger.

The Ford 9" has a really low pinion, but I'm fairly certain you already know that. If the CJ-7 is going to be wheeled, I'd stay away from the 9" unless you're going with a high-pinion 3rd member (which is cool, but pricey).

If you're going spring-over, sell the '86 CJ-7 WT D44 and go with the Scout II D44 rear. The appeal of the '86 is that it's a bolt-in wide-track D44. If you're going spring-over, you're best off to sell the '86 D44 to someone who's running spring-under, and using the money toward the Scout II D44s (or whatever other axles you decide upon).

If you're going bigger than 36s or so at some point, you should probably be looking at building 3/4- to 1-ton axles.

I swapped f/r scout 44's in my YJ converted to rear discs, chromo shafts running a 35" tread. if you got any q's let me know. nice thing is the scout d44 rears have the same shaft length left and right.

Don't mod the 86 CJ D44. Sell it like Craig said.


If you truss the C20 rear (assuming you have 1-pc shafts), replacing it with the Scout axle won't be much of a change. Its really the front D44 that will be the improvement. If you do the front, I'd do the Scout rear with it just so you have matching track and brake fluid flow.

what is better about a scout rear 44 compared to cj d44, or is that he can get good money for the cj d44?

Money. Its the only bolt-in WT D44 rear option that exists for CJ's. If you're going SOA, there's no point in using it since you're going to put perches on any other axle anyway.

Yes, but most people wouldn't use it by itself. What I was trying to say was run the Scout rear with its matched front (or another wider front axle) or don't use it at all if you're not going to narrow it.

Agreed, just throwing it out there

Would work good with a scout front or 79 down waggy front axle.

Yes, but many people have matched a Scout II rear with an OEM CJ WT Dana 30 front, and the stance looks good.

Currently have 4" lift springs. What would the guru's suggest with a spring over? Would like to get something that is a little less stiff.

Stock springs springover will net you about 1 more inch of height and more flex
