I would rather see this testing done by an outside company that has nothing to do with arb or yukon. I would trust the results better

I know you guys make quality products, but to me this video would be more credible if you did a few things. If you tested 10 of each, we could have a some more reliable #'rs. Also if you would show the ultimate yield strength of the second shaft that sheared. Who knows maybe the second shaft broke before the zip locker. One last thing, If an independent unbiased tester posted this, it would also have more credibility.

@freakmanhere Try it on the entire axis and then examine the damage

Repeat the test on a new one

Test the axis of the vehicle without removing the axis of the examination

To discover the consequences then tell the world

@MentalChainsawDude Also, the lower the gears in the diff or with a 4:1 T-case, then the more the TQ ratio exacerbates the problem.

@MentalChainsawDude Well, you should think about gear-reduction, since, with it, you also have a TQ ratio to deal with. Say an engine puts out 270lb/ft of TQ; a 3.4:1 1st gear; 2.72:1 low range; and a 4.10:1 RP in the diff: this equates to to over 10,000lbs of force. Now, if that was distributed equally, then you would have 2500lbs of force going to each axle. Considering you have about 60%/2 going to the rear that would be 3000lbs per axle; 40%/2 to the front or 2000lbs per axle.

6500lbs to break the axle. put another axle in and do it again ? the zip went to 6700lbs before it broke . so whats up ??

[kennewickdevildog]

Either locker seems pretty strong. If you are putting that much force onto your parts, you are probably doing something wrong or stupid.

Next build I do, a Yukon is going in. Built in USA- And better customer service.

birel........you do know they are Indian made don't you?

@pryorfire48, what you saw was the pin set came loose after break.. That's normal on all lockers when this happens. Pin set on differential is kinda like saying a pressure cooker have a pressure release cap, and when it pops then the lid is no good.. Same as this, pin set is no good.

[pryorfire48]

is it me or at 4:28 you see parts fly out of the case. I am not talking about the orange indicator on the chain. This is a piece of metal from the case, and since the video shows them pulling the axle shaft out of the side gear it's not the axle

I had my ARB spider gears explode with no damage to my Dana 35 rear shafts. The shitty little 27 spline D35 shafts should've gone before the ARB. Not to knock ARB, but an outsider test would seem more reliable,
