I got the 4.8L w/what i believe to be the NV3500, well it's time for a new clutch, it was somewhat a work truck befor i got it and the guy pulled a lot of stuff and now it's starting to slip, just wondering if anybody knew where i can find a good performance heavy duty clutch for one of these. All i can seem to find is OEM parts, OEM parts mean OEM performance, i need more. Any help will be appreciated.

 

I haven't looked into it much but I'll be replacing mine also here shortly. I'm doing a Ls1 swap and am going to change the clutch while the motor is out. I know they put a heavier duty one in the Joe Gibbs' 5 speeds but I can't remember which one. Might want to look into that.
