Which is a better combo? 37's/hp44.ff60 or 35's hp30.8.25

What would you run? Which would be cheaper? Which combo is suited for each terrain? Just an open discussion on these axle and tire combos. Assume stock drivetrain besides axles. Have at it.

37s 44 and 60.... are you kidding me?

I'm swapping in an hp 44 with a 9'' right now, and would never even consider building a 30, or 8.25.

not to mention the 30 and 8.25 can only handle 35's with lockers at the max, why limit yourself? Then you just have to start all over and do it again if you ever decide to go bigger. I'm planning on running 37s now, but have the option to go bigger if I feel the need.

I know at least 100 people are going to chime in on this thread saying they run 36's on stock gearing with the 30 and 8.25, and that you never need to go bigger than 5'' of lift and 35's to be the most capable jeep on Gods green earth, but lets just be honest with ourselves and admit thats wrong.....very wrong.

sure the 30 and 8.25 are completely reliable axles, that are a great platform to build on for the jeeper that knows they will never go over 35s, but for people like me, I wanted options for the future.

just my .02

let the flaming begin.

Well what is your projected price on the swap? For jeepers cheaper is always better right?

this is true.

building your current axles will be much cheaper, but at the same time you limit yourself.

since I got a deal on my 44, It looks like I will slide in at 1500 bucks per axle if I don't run into other problems.

not to mention 37's are expensive as ****.

Im going 37x14.5x15 creepy crawlers, and MT classic locks.

nearly 2 grand for that combo alone.

Keeping the 30 and the 8.25 is MUCH cheaper, and they can run 35s, if you have the money, the tools, the ability to have your cherokee sit on jackstands for months, and the know how. Do the 44/60. or even better yet, if you wanna build something even sweeter, you can get axles out of a CUCV, pas. drop dana 60, and a 14b both stock with 4.56 gears, and the rear has a detroit locker, and then run a flipped 4:1 dana 300 transfer case.

But you're limited now by your front. You can't go much bigger than 37's because of ujoint size and whatnot. So I think in order to truly not limit yourself, as you are claiming you are not, one would need to run tons at the least. Make a steering 14b front and run a Dana 80 and call it a day if you truly dont want to limit yourself. Or just build rockwells. I think building the 30 and 8.25 or 44 for 35's is perfectly fine. But if you want to go bigger, go straight to tons and don't even mess with anything less than a D60. That's my input on the matter

You think a guy could build a 30 and 8.25 with alloys and full case lockers, beat on it with. 35's and be fine? Lets just say 37's are the Max size for the 44/60. What would be prices for each choice? I got 3700 to build the stock ones up.

I think you could. Truss both. Strong diff covers. And like you said, full case lockers and alloys with good ujoints up front. Cal over on NAXJA had a 30 up front and 35's and would run the hammers with that combo. Says he never broke anything. But if there is any chance you will go beyond 35's, just do an axle swap.

it really depends on how and what you drive/wheel

If your going out on the rocks and don't give a **** about anything while trying to get up the rocks, plan to trailer it and drop a **** ton of cash into your axles, or tailer the jeep everywhere... build full widths

Hp30 and 8.25 will handle up to 35s after gearing, and depending on how/what you want to build it to. It will still remain pretty streetable also IMO

I run a hp30 and a ford 8.8 on 35's and I'm happy with it right now. I DD my jeep and wheel local pretty often, so widths don't make much sense in my case. 8.8 is getting a detroit locker soon, and both axles will be getting trussed and braced in certain spots for prerunning reasons. Ill never lock my h30. Everything is to small for me to trust dumping the money into or leave me stranded. I don't think my setup will change much, I may swap in a wagyy 44 if I find one before I brace my 30 the way I want to though

35s will get almost everyone (with xjs that is) where they want to go without breaking the bank to bad. Everyone else is just overcompensating for other things IMO

true, didn't think of that, although I have seen bigger tires on chromo'd 250 44s. but Im not saying its right.

35s will get you most anywhere, but I do like the look of an XJ on 37s, annnd I have the budget for an XJ on 37's...."compensating" has nothing to do with it.

and 35's on built stock axles will be fine for most.


BUT, if you really wanna have some fun and be able to just lay into the throttle over some rough terrain and not have to worry about if you're going to break something....then bigger is always better.

I'm the throttle down type. If I'm going to truss the stock axles and do a 3 link wouldn't it be the same about of work as a swap?
