The clutch worked great for a year or so. I've since swapped it out for a new aisin clutch, ordered from amazon. The new one is the same as stock.
I only swapped to the new one since I was having some overheating issues, and I completely overhauled the cooling system. New thermostat, new fan clutch, new hoses, and added a digital temp gauge. No problems since then.
I can hear the new clutch engage when the truck gets hot, and the modded clutch was always engaged.
