Anybody run big tires on their 1 ton setup? My 14bolt is stock shafts but my 60 is 35spline chro-mo's with super joints. I run a variety of trails from the rocks at the Hammers to the dirt notches in the desert. I've got an opportunity to run 46" baja claws and was curious if my axles could handle them. Ideally I'd run rockwells with them but budget doesn't allow for that anytime soon.

Anybody on here run big meats on their rig?
 
im sure someone has, scrath that im sure many people have and id guess some have lasted and some have broken. It would all come down to your driving style. Ive seen 10 bolts take 38s all day and not quit, and on the contrary ive seen tons broken with 35s with a guy that couldnt keep his foot off the long and skinny one.
 
I think knuckle strength somes into play with tires that big too. Probably spindles, bearings, and everything else too :)

but I'll be on the lookout for you at gorman when you end up sporting 46"s hehehe
 
Its all about reliability. If you are a throttle guy then absolutely not. You have to know when you are going to break, and avoid ( or be able to afford) those situations. Making sure the tires don't rub is huge, if they are bound up against the body and in a huge hole or undercut you will break with 44s and up.

I have seen a couple guys successfully run 47s 46s and even one guy 49s on tons. They all have since gone to rockwells except for one guy and he bought 44s.

Weak points in the 60 becomes the ring and pinion. 14 bolt seems to let go on the pinion where as the 60 will strip teeth on both.

It seems the 14 bolt handles it better than a 60.

Sure it can be done but you need to know when to back off and ask for a winch unless you want to be constantly replacing parts

Thats what i have seen also. Seems the 14 bolt fronts hold up pretty good but still depends on your driving style.
 
Those that wheel with me can verify, I'm not easy on parts, I don't have that 516 for the fuel mileage :whistle::whistle: Part of me says wait on the tires and spend the cash on linking the rig but then also if I'm going 4 link and coilovers I want to run nothing smaller than a 44 and I think 46's are a good start. :confused::confused::confused: decisions decisions

watching you race across the mud hole and around the offroad area at Gorman...I can verify this. :waytogo: You need a dirtbike or quad :D
 
Big huge tires on tons is gonna necessitate things like plating the knuckles, gusseting the inner Cs. As said if you're going to do it the ring and pinions start to break. There is a kit out there to stick dana 70 gears in a 60 case up front.

Also those super bling CV shafts for the 60 are suppose to be a lifetime warranty up to 49in tires.
 
Don't forget to weld the center section of the 14 bolt. I've seen a couple of those spin.
 
I personally have no experience with tires above 40" but I know people run 44s all the time on tons,some shatter cromo shafts and some have no issues with stock shafts,so I would say it depends on ur foot

This guy runs the 46 claws on tonnage and Im pretty sure he has really only busted up the ring and pinion, Iv seen his rig in action at TSF and he is pretty light on the throttle in the rocks.

Here is the link to the build on pirate...http://pirate4x4.com/forum/showthread.php?t=641709

He has broke multiple Yukon chromos and he cracked his reid knuckles as well.

Here is an excerpt for his build thread..

I am certainly convinced that 46's are the breaking point for a d60. I ran years with 44's with no issues but since the claws I broke 3 chromoly shafts and wasted the lower bearing on the kingpin.
he is also now doing this...

I have ran 47" LTBs, 48" Michelins and 54" Boggers on 1 ton axles. It is easy to break parts with those tires. I would suggest 2.5 ton axles with at least cromo shafts or Dana 80/Rockwell/Ouverson hybrid axles. You can dump $10,000 into some 1 tons and they will still be weak compared to the better options.
 
The guy selling the tires on in my 4x club. He is selling them cheap. He wants me to run them, but no way could I run 46s. If they were a 17" rim, I would find some wheels for them. But they are 20" tires. God knows I am having a hard time getting my rig back on the road now. If I ran those, my rig would never run again.



Mtnman, better get them quick! They wont last long.

HAHA for a second Norcal, I thought you were running the 44's and then i re read the post, But ya i just saw that update about breaking the knuckle, guess i over looked the broken axles. I mean i wonder how much heavier the 46 claws are compared to the 44 boggers or even 44 tsl's?
 
I talked to Poorboy and he said basically if you baby them, the axles might hold for a little while with mild wheeling. And if you throw good chro-mos at it, you might last a couple trips but then you'll start snapping axles and ring and pinions. So it looks like no big meats for me until the rockwells go in:whistle:
 
you can get shafts that will be stronger than a Ring and Pinion but eventually you'll need to go to D70 gears in the 60 housing or 14-Bolt Front.
