Well, I know the guy on the jeep site talks about measuring the thickness of the puck every 5-10 pounds of torque. He has ALOT of torque on that puck. Quite possibly more than realistic. I might have to pick up a hockey puck sometime and see how much torque it takes to get it that far. Anything over torqued will fail, even the fiberblocks that you now buy for body lifts. Have a great weekend.
