Crown automotive chromoly dana 35 axles

Will the crown automotive chromoly 27 spline dana 35 axles hold up with a locker and 32 inch tires?

Maybe. The D35 may last forever locked on 35s or grenade when taking a turn on the street. You never know.

They are supposed to be 30% stronger than OEM. I guess it depends on how you drive, and also on what type of locker you have. I think that they will last longer if you use an open diff that if you use a Detroit Locker. I ran Moser 27 spline shafts for 10 years with 33 x 12.50 and ARB locker in my D35 with no problems. I am changing the shafts for 27 spline chromalys from Crown because my shafts were starting to pit and I don´t want to spend in changing the ARB locker to a 30 spline.

I have them but with the factory traclok which is only 35% limited slip and 32'' all-terrain.I feel pretty safe with that combo and i trust it to hold for a long time!!

I have to agree.My D35 unlocked held up to 35's for over two years. (before I sold it)

I was reading a post the other day that suggested IIRC that you can change the 27 side gears on the arb to 30, once again that is IIRC. Only thing I look at is what type of chromo material they are made from.

Ok but a locker can more than double the amount of torque sent to a single axle shaft... so much for the 30% stronger axle shaft being good for much reassurance.

I recommend consdering the route of a Super35, that way the shafts are 30 splined and the kit defaults a softlocker. The Crown would be ideal for a LSD such as a TrueTrac as the TrueTracs do not offer a 30 splined option.

You'd be hard pushed to break the axle shaft under torque alone, it's the sudden torque applied down the shaft from a spinning tyre gaining traction that would do it, which won't happen with a locker and an easy foot.

Don't say it can't happen with a locker and an "easy foot" as it happens. Simply put, if you double the torque the axle shaft was designed for, of course it can happen. And try telling that to my long-gone Dana 35c's axle shaft and locked differential that grenaded during a u-turn at a light controlled intersection in downtown San Diego without tire spin. Or the time I broke a front axle shaft without tire spin while on Sledgehammer in Johnson Valley with my locked Dana 30 and 35" tires. That's just MY personal experiences, many others have similar stories to tell about what happens to stock axle shafts after a locker is installed into the axle.

And many more have no story to tell at all, whats your point?

If you didn't get it after two different explanations, there's no point in throwing more words at it.

Oh i get it allright. It's just that running mine locked for around a year or so and using it every weekend on various trails, in fact just got back from a weekend in Moab, im still waiting for it to fail. Sure I may not drive the real hardcore stuff but for the wheeling I do it's fine, just as it would be for a lot of others.
It may break one day it may not but until that day the money I haven't spent builds interest. Thats my point, sorry if you have a hard time accepting it.

the dana 35 is a good enough axle for a stock jeep ... which is what it's ment for. The fact that it doesn't respond well to modifications such as extra weight, larger tires, or a locker is a definite problem.

The fact that people wheel with it locked on various tire sizes isn't proof that this is a SOLID axle.

I've been running the Yukon "HD" 27 spline axleshafts made out of 1541H alloy. Not as strong as the chromo shafts but they've held up very well under my Jeep with it's 32's and Truetrac LSDs for over 4 years of offroading now. Unfortunately, they were the only "HD" 27 spline axle shafts I could find back in the day.

I really like the function, traction improvement, and manners of the Truetrac LSDs. They don't offer the same traction as an actual locker but it's not critical on the trails I run and I appreciate that an LSD is easier on my axles and drivetrain than a locker would be. Not to mention the stock-like great on-road manners.

But if you're looking for a locker then I'd probably go with a Super35 setup. There is also the Superior c-clip eliminator kit. They also have a 27 spline chromo axleshafts but Superior has some slightly different eased profiles to some of the machining that beef up the axles strength as well as new pre-on bearings that allow you to get rid of the c-clip design. They've proven to be a very stout kit.
