Which rear axle do you think is best and why?

Okay I have a 96 ZJ, 4.6 stroker and a custom 42/46RE trans.

I am in the process of planning out my full width axles. I will be doing a HP60 in the front and need some opinions on what to put out back.

I want to still be able to drive it on the street (not as a DD) but to and from the trails. I will be running 38-42" tires, full spool out back, I don't just rock crawl, I pretty much like all types of wheeling so I want a good all around axle.

If I go 14b it will get shaved so ground clearence is not a huge issue. I am concerned that the 5.38 gears may not be low enough with the big meats and my 6cyl.

I def. want a FF'er, 8 lug. I will be running Clayton's long arms, Clayton's high clearence brakets on what ever axle I end up with.

Well I think that pretty much explains what I am looking for and some info on the Jeep and my driving, so what do you recommend?

I voted 14 bolt. They are cheap as hell. They can be shaved to save a TON of ground clearance, and there is alot of developed and developing aftermarket support for them, and in stock form they are stronger than any of the other axles on the list.

Your three poll options are very different.

The 9" is a SF half ton axle, with five lug bolt pattern. Can be cheap, or blingy expensive.

The 14B is big, FF, with eight lug pattern. Fairly cheap.

HP60 would be a custom only option, $$$.

5.38 is as low as you can go in a HP 60, so lower gearing options is a non-issue.

Yes if I went with a 60 it will be a RockCrusher center and then the rest custom made. That is what I am planning with my front HP60 already.

I thought you could go up to 7.x:1 gears in the 60's?

I am planning on either a Stak TC or a flipped D300, I will have 4:1 gears in the TC so if getting lower than 5.38's at the axles really worth it?

I am leaning towards the 14b due to the cost and with the money I will spend on the front I really don't want to break the bank out rear also.

Any other opinions??

You can go all the way up to 7:17 with a LP 60 but 5:38 is the highest for a HP 60. How about a LP 60 in the rear?

The gear ratio topic is pretty much killed because he is running an HP 60 in the front.

If you were looking for gearing options the 9" is the king, that thing goes all the way from either 3.10 or 3.55 all the into the 7s or so.

Thanks for the clarification.

I think if I am going to go to the exspense of building a rear 60 I might as well go HP.

Yes the HP is nice and I agree. But is still will be cheaper to build a LP. Plus when your at the 5:38 gear level and running a HP in the rear it starts breaking ring and pinions, although the LP is not much stronger in the gear department it is alittle. My .02

"I will be running Clayton's long arms, Clayton's high clearence brakets on what ever axle I end up with." GREAT IDEA ON THE CLAYTON STUFF I KNOW HIM PERSONALLY AND HIS STUFF IS SECOND TO NONE. I VOTED 14B BECAUSE I MADE THE MISTAKE OF BUILDING THE 60 AND COULD HAVE SAVED SOME CASH AND STILL BEEN STRONGER WITH THE 14B.

I do not want to get off track by comparing long arms. I will be running Clayton's also and honestly that is the first time I have ever heard anything negative like that about Clayton's.

I think I am still leaning towards the 14b just from a cost stand point.

I voted other, cause I would pick a Dana 70. You can get them in way more forms then a 14b (D70, D70U D70HD etc.) some of which are noticibly stronger then a 14b. The basic D70 is often said to be a smidge stronger then the 14b actually. I'm a Dana/Spicer man myself.

A buddy of mine actually has a D70 housing from a DRW vehicle he said I could have for free if I wanted it, it is just the housing.

I am not really familiar with the D70's though. The pumpkin is the same at the D60, but has a bigger Ring gear correct??

I would go to the junk yard and spend about $100 on a 30 spline LP 60. Put new perches on it new R&P and a locker and call it good.

Now ya see it all matters on what you are going to do with your vehicle and how big it is. If its a Samurai I think a 60 or a 14 bolt is a tid bit over kill and a 9in. or a 44 would be perfect. Now a fullsize would require a 60 or 14 bolt without second guess. But for your ZJ build up I would deff go HP 60 up front with a 70 or a 14bolt out back.

X2 CLAYTON STUFF DOES NOT GRENADE ON ITS FIRST TRIP ATLEAST NOT IN MY EXPERIENCE. FURTHER ON THE REAR END I HAVE BROKEN SEVERAL 30 SPLINE REAR 60 SHAFTS SINCE I GOT MY NEW ENGINE BUILT.

I voted 9" just from info given. I've seen custom modded 9" centers that held 10" ring gears and had 40+ spline ff axles that were like 2-1/2 to 3" thick on prerunner rigs built for baja, in Tucson that run around $8grand. I didn't know there was a $$$ prerequisite. My bad. Hopefully, I'm going to build one of these soon as cheap as possible...

Read my post above and go with a LP D60 it is stronger and cheeper than a HP D60 and you don't loose that much clearence. You could spend $8K on an axle or you could build a stout rig for $8K and still be good with the wife.

I don't see why this would this be a better option than a shaved 14 bolt unless a R&P ratio lower than 5.38 is needed...
