Axels and Bearings are holding up great.. Havent broke an axel yet. I have however bent some axels.. The tires I use are 10 ply quite tall 7.00 15 and have 3/4 of mud grip these rubber are about 65- 70 pounds each.. I use a 4.30 and 4.56 gear ratio.. I only way I think I could break an axel is doing forward to reverse drops or getting hit on the tire when im on the throttle.. The main reason to these bearings over the roller ones is if an axel breaks I dont want it to walk out of the housing through the bearing.. Which would probably cause me to lose the race..

Thanks for all the input guys .. it always nice to have something to talk about in the winter season
