Hd Dogbones suck!

[Racer 1966]

I broke a dogbone on my Svage 25 last weekend. The LHS only had the chrome "Heavy Duty" replacements in stock, so I bought them. Put one in and after less than 1 1/2 tanks of bashing (in snow), SNAP! It broke! Put the other one in and before I emptied the same tank, it tore up the locker rear end.
I know the locked rear puts more stress on everything, but I've run 3+ gal on the originals. The one that broke has been bent for at least the last gal of running. So why did the heavy duty break so quick?

Metals react differently especially in snow. in weather that cold can make most anything metal become weak and brittle.

How are your drive cups? If they are notched (grooves wore in them from the dogbone ears), they will break dogbones since the ears of the dogbone will get hung up in the notches. I had notched axle cups break CVD's on me before.

The HD dogbones really aren't any better then the regular dogbones. In fact it seems like the HD snap more then the non HD ones do. I had 8 gallons on a set of regular ones without any problems at all.

I work with metals everyday, it's my bread & butter. With ambient air temp of 37 and melting snow, it's not cold enough to weaken most metals. I believe the HD bones are just too hard and brittle from the factory to flex enough to work well in this situation.
The drive cups on the other hand, I believe warrants an investigation. Thanks for tip Olds.

I've also noticed the savage suspention sometimes lets the a arms drop to much, causeing the cup to eat at the dogbone rite below the ball and ears causeing failer. look and see if its eating at the bone there, could be that plus the cold weather, I have also noticed that the harden 1's dont seem any better that the black 1's. I went with mip cvd's expensive but tuff as nails.

I'll have to investigate that too. I'm sure our big snow jump didn't have anything to do with it ! Here's a few pics of the fun.
