Best clutch for 6.9?

[Keeway]

well my clutch in my 85 6.9 4 speed wasnt the greatest but since i sled pulled my truck the other week its slippin pretty bad i think i glazed it over. you guys have any ideas which clutches are best for the 6.9s? i need a clutch that will hold up to hauling a heavy trailer and occasional sled pulling. thanks
