Had a great conversation with Brian Ellinger night before last. He reviewed the testing procedures, torquing procedures, and issues involved, which I won't go into - but Trail Gear's comparative testing was not exactly on the up & up. I will not be using the six shooter knuckles due to several factors, but will be ordering FRORF's ARP studs and locknuts.

Brian was very leery of welding to my older cast All-Pro arms.

FWIW, they use stock knuckles on their project truck with a 2" ram, plus his ARP studs and locking nuts PROPERLY TORQUED (>100 ft./lbs.) and they have never even had anything go loose, much less move.

Convinced!
