The ZIP Lockers have gotten a lot more expensive these last few years. They entered the market with a cut rate price to grab market share and have since been increasing the price.
Dana 60 ARB: $1157
Dana 60 ZIP: $993
Not a whole lot of difference there. I'll pay a 10-20% premium for brand name reliability, track record, and quality any day. Check out

I am not sure what bugs me more. Bad marketing or bad application science.
I don't run ARB or zip lockers so this is just a general observation.
From the marketing side,
1- a head to head test should be non biased and transparent as possible. So not telling which vehicle application is being used and the cheesy commentary by the techs would suggest both bias and lack of tranparency.
From the application science side.
1- Does it really make sense to only have one axle in? I would be more curious to see how things explode when torque is being applied to both sides of the cases. If you are applying that kind of torque to one axle shaft in a wheeling application that tire is REALLY REALLY bound. Which leads to the next questions. What are your other three tires doing and Why are you still hiting the gas?
2- Without application information my first question is it possible for the parts in question to be able generate that kind of torque. It kind of like saying these tires are bad because they can't hold up at 350 mph when they have a speed rating of 98 mph.
Yes you hope that your axle/u joint/hub will fail before your locker but if ARB wasnt nervous ZIP the video would haven't been produced the way they did it.
More transparency/less bias would have achieved the same result of customer education without the resulting speculation.
