Seem well built
Im running these on a sand truck and spent alot of time looking for something like these. I have used johnny joints before but sand sticks to all the grease and turns them into an abrasive mess. These look WAY better than a big yellow forged joint and the fact they are sealed is just that much better. So far I love them. We will see how they hold up over time.
Thanks Ross! The built in "life seal" should prevent sand from getting to the races. Be sure to keep us posted!
