What clutch for 39's or bigger?

[jovibuilt]

What clutch do you guys recommend?Its a 1992 explorer with 5.13's and a 5 speed and I am putting 39.5 Iroks now but maybe bigger in the coming months.I have used a centerforce II in the past,didn't know if there was anything as good but cheaper.Just wondered what everyone here is using for extreme duty?
Centerforce II $289.00
Zoom high performance $274.99
Anyone have any thing else to recommend?Please no flaming for the tire size.Just opinions on a clutch.Thanks
