***Berg XR10 Hybrid Axle Pre-order***

[highlandcrawler]

Well testing is done and I have production all but wrapped up. The first ones will be ready to ship out on Wednesday. I made a batch of 6 pairs and will take pre-orders on them until they are gone. If you haven't seen or heard of them you can find info in these builds.

Nice product

[TSK]

Beefy.

[SDS Customz]

I would agree that these are a "nice" product, though I will pass on a piece of advise. look at the drive tangs as there is room for improvment, while you are goin to all the work. other then that they look good.

[Chevdog]

They look great, cant wait to get my set. It's nice having another option other than 300's. Less expensive and hopefully more available. From everything I've seen, the xr universals are nice and tough. Thanks for making a product that a lot of us out here have been wanting since we first saw the stalker.

The pic has not been updated in this thread yet. Those ones pictured are the prototype ones that were cut by hand. I assume you are referring to the fact the flat is shorter than the tang and did not engage all the way correctly. That was an early mistake and why we make pro-type pieces. You can see in the pic below of the current ones being shipped the tang is twice the length and the locating pin is max length to make assembly easier. The tangs engage fully and the 2 tips almost touch in the middle. Also when you use the little "air quotes" on a word like nice most people including myself take that as sarcasm. I'm sure thats not what you were implying but just letting you know. I wont say these are perfect and the best thing on the planet but they are a great option for someone looking for something different at a reasonable price.

They look a lot stronger than the inner shafts on my xr, and they have been nothing but bulletproof.

I think what sds is referring to is the 90 degree corner. It can cause a stress riser to occur at that point and allow the shaft to twist in relation to the flat spot. A radius from the flat to the od of the shaft will be the strongest

This is a true statement however I believe most lockers with strip long before the shaft. I've been wrong before though

Thanks for the helpful insight. I will work that into the future models. It would be as simple as having the machine cut the flats from the side. That would make a cleaner flat also without the 2 passes from the mill. During testing there was no twisting even after destroying lockers so that addition will make them super stout.

x2 as we can look back on ckrc and there rear shafts that would twist off
at the 90. if you where to use a round end mill or flip it 80 deg when mill them you would have a rad and not a 90. but i likey and need a set

[davec]

Hey, Erin, get me the CAD file and I can run some FEA for you, both with the flat and with a radius. Happy to do it for you free of charge. PM me and I will give you my e-mail.

That is an un-fair comparison Lars. CKRC was using poor quality metals. I am on the phone with Erin now, and we are talking about putting the radius in it. But I will say that the proto's that he cut for my berg have less drive tang engagement, and no radius in it, and they haven't given me any shit. So I don't think that there will be any issues with a 90. But doing a radius will not hurt either

Not sure, but 80 degrees doesn't seem quite right to me.

[Hoppa]

You could also just use and end mill with a small radius and not have to side mill them. That way the the machining process doesn't need to change.
I'm not to concerned with that being a stress riser. It didn't stop me from ordering a set.
Way to step up and be innovative.

When Erin saw my build thread, and decided he wanted to build one is when he came up with the idea of just machining a whole new shaft. I'm sure I would have eventually thought of it... after much frustration later lol. Sure beats the hell out of trying to join stuff together.


For those concerned with strength, I have been using these in my berg in the thread below. The truck has far more power than I know what to do with, and the axles are holding up great.

Dose the pin at the end of the axle shaft keep the axle centered in the locker? I guess i could just pull my rig apart an mic it.

Yes it sure does, without it, it will just slop from side to side in the locker

[Wilard77]

Are these for sale or just pre Order

[oneeye]

Ya I would like a set of these wth 6 mil outers that will work with ax-10 outers. A direct replacement for the 300s
