I just purchased this truck back in March and have only put on 2K miles or so but the the clutch is slipping pretty badly and its time for a replacement. Right now the truck is stock besides an intake. In the future (could be a couple months, could be a year) I plan on adding an exhaust, hydra chip, and 160/30 injectors, I plan on keeping the stock turbo and HPOP unless they cannot handle the extra load. I have pretty much decided on a clutch kit from Southbend given the numerous favorable reviews I have read for this application. Right now I have am having trouble deciding between the 1944-6OKHD which is rated for 425hp/800tq and the 1944-6OFEK which is rated for 475hp/900tq. I know with the mods I listed above I will probably struggle to even break 400hp. So thats where my question comes in, will the truck be comfortably driveable if I install one of the above performance clutch's on basically a stock truck? I do a bit of towing (average 7K-10K lbs) and I dont want to render the truck useless by putting to much of a clutch on it. But I also don't want to have to buy another clutch in a year or two by putting a lower hp one on and having it wear out prematurely after the truck has a few upgrades. Any input is greatly appreciated, would love to hear from someone who has firsthand experience with one of the above kits or if anyone has a suggestion on another brand I would love to hear it.
