I've mounted a lot of beadlocks, and for some reason those KMC beadlocks and Coopers I was running also "kicked my ass". I had to make plates to mount to the wheel every 4-5 holes that would hold the bead down as i went around the wheel.
I swapped to a set of Trail Gear beadlocks and Maxxis tires a couple weeks ago and did the whole set in the time it took me to do one of my previous setup.
