I am doing a 5 speed manual conversion on a 99 Dodge 2500 Cummins 5.9L and am looking for recommendations and pricing on a good quality clutch setup.

It will tow around 8000 lbs from time to time and I have plans to pump up the HP in the future so I would like something that engages smooth but can hold up to 500-550 hp if such a thing exists.
