Who uses grouser bars? Where are they most commonly used?
Are you talking about the weld on (refurbishment) type?
Yea, the heat-treated grouser bars http://www.4ncorp.com/products/heat-treated-grouser-bars/
I used Dura tuff weld on ones to build up the tracks on my D8H a few years ago. They worked good. http://www.duratuff.com/
I've seen rebar used, too. For what its worth, don't build up taller than original height. doing so risks breakage of other UC components...
