    Michelin XL\'s

    Ok I was going to run the 41" XL's on my one ton, but I have since desided to completly remove the body and build a tube chassis. Now I am wondering if I should have gone bigger. What is the limit for my D60? I have not changed the axles or anything except to ad X-over and rock ram. I have a set of John's 20 dbl beadlocks. /forums/images/graemlins/1zhelp.gif

    Stick with what you've got. You're at about the practical limit for a 30 spline '60.

    Still at the limit. I would not run anything than bigger than 44's on a D60 front. Maybe 46" Claws if you're lucky. The Michelin military tires are true size tires with heavy side walls.

    I wouldn't run the Yukon stubs, there not hardly any stronger than the spicer stubs. If you want to get serious and run the Michelins you should go up to 35 spline Superior inners and outers with CTM joints. Thats the minimum. Also probably want to run drive flanges.

    Re: Michelin XL\'s

    right now that is not in the budget. My wife just aproved the new bender and notcher and the wheels and tires so I have to wait for the upgrades for the front end for a while. I just want to not have to wory about breaking things unless I deside to do something dumb! But I also don't want to miss an oportunity to get bigger rubber if I can.

    44+ requires 2.5 ton I would say.

    Rockwells aren't much stronger than a D60; 1.6" isn't much stronger than 1.5" especially considering that they are old and were probably poorly forged.

    41" michelins are a good tire for the D60 IMO. remember, michelins are pretty heavy tires for their height. I wouldnt be surprised at all if that 41" michelin weighed more than a 44" TSL.

    ummm... then a) why are they rated at 2.5 tons.. you make it sound like they should be 1.5 tons... and b) how come peeps seem to be able to run 48 and 52" michelins.. beat the HELL out of the axles, and they rarely seem to break? Im sure some peeps have broke em... but even the guys over at pirate who think of $4000 D60s as merely "acceptable" seem to think the rockies are the axle to have for super huge / heavy tires.

    Re: Michelin XL\'s

    Well, they are 2.5 tons because they have massive bearings and massive gearing. The 2.5 tons doesn't sit on the shafts so whats that have to do with anything?

    You can build up a rockwell with 2" 50 spline axles and 50 spline spools and drive flanges and be big pimpin though /forums/images/graemlins/grin.gif

    Can you say 2" 50 spline shafts?

    [​IMG]

    Thats the 50 spline compared to a stock rockwell stub.

    Ohhh baby /forums/images/graemlins/thumb.gif

    Re: Michelin XL\'s

    that is some bling stuff! me likes! at any rate, i was being a lil bit smart azz when it came to my "why 2.5t" comment... the real point is that people run HUGE/heavy tires on em and run em HARD and they dont seem to break hardly ever... so while the shafts might be a "mere" 1.6" or whatever, it dont seem to be holding the axle back much.

    I agree. I have seen MANY rockwells shafts break. I have several friends that run them, most have broke them. I know for a fact that "The Ogre", or the buggy on 53's that was in Peterson's Moab edition has broke 16 rockwell shafts. Extreme example, yes, prove a point, yes. I could go on and on with examples of broken rockwells. It all boils down to the fact that you can build a D60 to perform much better than rockwells do, but they cost about 4x as much.

    Here's my smartazz comment jekbrown, do a little more research before you post.

    Re: Michelin XL\'s

    I know a lot of people running 44s beadlocked on dana 60s and most dont have problems its all about how you drive and im talking about hard core rock rigs not the family camping wagon. I also know some guys running rockwells and have never ever seen them brake running 46s up to 52s. but its like I said before its driving style I pesonaly have enough power to ease up and over things that others are full throttle bouncing like crazy and SNAP there goes an axle joint in a 60 with 39s. /forums/images/graemlins/thinking.gif

    If I remember right, Rockwell shafts are only 1.62" at the splines but neck down to 1.45" for most of the length of the shaft.

    Re: Michelin XL\'s

    That is correct. I guess that would make them not even as strong as a D60.

    Care to explain this comment? Stock D60 shafts necked down to ~1.3" untill the earily '80s. All the stock stub shafts were 30 spline and ~1.3".
