I got rid of them since they were lighter and I believe 6 tons. The conversion is 2.5 x rating for a snatch block so the Smitty was really 33k lbs. as I remember. They were more suited for a 15k winch like the warn M15000 which has a smaller cable that can take a tighter bend radius. SuperWinch makes the [FONT=Arial, Helvetica, sans-serif]Superwinch Swing Away Pulley Block — 36,000lb. Capacity, Model# 7755. I bought one of them and decided I needed additional hardware to keep the unit from twisting. Maybe I am a little paranoid about things breaking under a shifting load! So I keep 2 Warn snatch blocks on board, some nice 3/4 chokers, Some additional cable and 45k straps. I plan on getting out one way or another. [/FONT]
