Locked front and rear, on 32x11.5 BFG muds. bds lift with lower control arms.
Rig goes where i want for the most part but i want to be able to do more.
I feel like tire size is my limiting factor now. and lack of power/no wheel speed.
I guess i'm at the point where i want 37s minimum. yeah, i nkow what that entails.
If i actually do get new axles to handle the tires, will regearing get me enough power?
As it is now, 4hi is almost worthless unless i'm on flat ground. so for hillclimbs, i have to do it in Low and then sometimes I can't get enough wheelspeed to get the tires to clear out.
The rig does very well for what i have in it, peopel are always surprised, but i think i'm ready for the next level.

For me its my reluctance to do serious body damage. That is what holds me back. My little xj rules the hills. Its pretty low and good power. The rigs with huge tires can not carry the wheelspeed to get up the serious hills.(meaning high wall types)
In the huge rocks it is limited by tire size. That is the ONLY place so far where I felt tires size is an issue.
Next level for me would be what atmos suggested. A high pinion 30 built pretty well. And 35's.
Any more and I am going to just build a buggy.
A tip though. low range is much better for mud bogging, hill climbing, and basically any off road. High range has wheel speed. But its the thrust and drive that gets you up and over. Not 50mph wheel speed.
Anyone who wheels in high range does not know what they are doing. And no offense to anyone.

OK, . Let's see a picture of your jeep. Show us a picture, and we can better help you.
Because you ain't wheeling high range up steep hills with 37’s in a jeep. Its not happening.
And I could be wrong but I don't know any rig that runs high range successfully off road. I have seen some hill jacks in pick up trucks do it. While I sit and smell their tranny fluid burning.
And again with tons and 40's. High range ain't happening. No offense at all. But if you had 500hp for the tons and 40's in high range(which would be the minimum. What tranny will hold together? What clutch? And if that held what transfer case?
I appreciate your enthusiasm. But its not happening. High range is out. The larger tire you throw on there. The slower you will go. No matter the gearing. Rotational weight is against you.
My xj will pull second gear low range up hills. Going scary fast in my op. And I have 32's with stock gears. Fast enough that if you hit a bump you can't control it.

the rigs i'm talking about have built trnny's, built TC, etc. pretty much nothing stock.
I guess what i'm getting at is that an xj isn't the right rig to get 500 hp , built trans, etc. and spin big tires.
on these hillclimbs i'm referencing, i get about halfway up and the tires clog up with mud and 'im done. foot to the floor in low. tires aren't even close to spinning fast enough to clear out. whereas the high power rigs just keep the tires spinning and make it up.
are you guys making the muddy hillcimbs pretty regularly? maybe my junk has a worn out engine. only has 140k on it, no smoke. havne't checked comp. though.

so maybe my question is, to put it simply and eliminate the other stuff...
what do you guys do when you're halfway up a muddy hill and your tires aren't cleaning out and you're taching it out and y ou just aren't spinning them fast enough?

ok, now you are making sense.
I don't know? For starters are your treads fresh? New set of aggressive tires will do wonders.
On muddy hill climbs in low range I take off in low 2. So it starts in 1, shifts to 2 very quickly with it flored. And I can carry second mud a flying no matter how steep the hill is. Yours should do the same. Mine is just stock. with 158.000 on it. Runs great though.
I will be going to 35 10.5 boggers and 4:88's when my second set of technos ware out.
I mean for your net level you could drop a FI v8 in it? If you want the power route. For me the I6 works great.
I run the techno's.

I would say a different tire is what you need of your caking up half way with tires spinning how worn are your tires... I run 33's a rear locker 6.5" lift and have never had an issue with anything any of my buddy's do with their truggys and super built rigs

my BFG Muds are in damn good shape. never seen the street. maybe they're just not aggressive enough for the clay mud we have here. at least 75% tread depth.

Anyways when I saw them I knew I had to have them.
Your tire choice is not all that bad. But if guys are making hills and you are not, something is a miss. The xj is usually a good hill climber.
Maybe a more aggressive tire?
And if your not pulling second gear on the hills you may need to regear. Second floored should clean those out enough.
Also I have found the narrower tires to work better on hills like you are describing.
If you are dragging your diff uphill then you would need larger tires. Otherwise no.
I shaved my rear diff an inch for added clearance. And raised my lower shock mounts

oh god these suck in the mud! they cake up and become useless in a matter of seconds. and dont clean out. switch to a much more aggressive tire that cleans out the mud better. the BFG's are amazing on rocks. but as soon as the conditions turn wet you're screwed

Yes they are a copy. Techno out of Canada makes them. Often thought about becoming a dealer.

I do the same thing as you, climb in 2nd and it does great when it's dry.
how did you get hold of those tires?
thanks for the help boys, guess i'll be looking for some new tires!

and yea, you need gears and better tires. KM1s are not mud tires.
