I've heard guys say they put an Edge Comp in their truck and it immediately started to slip the clutch. I've hauled tractors, cars, camping trailers and other various things with my truck. I had 42,399 miles on the truck when I installed my Comp, I now have 82,327 miles and the clutch holds fine, guess I got a good one. I have even done one truck pull with it, kinda hoping it would toast the clutch so I would have an excuse to put a serious clutch in it. I drive with my Comp on at least level 2x5, but usually 3x5 and when I first put it on it was always 5x5. I won't say I abuse my truck but I don't baby it either. I am a downshifter and always have been, must be from learning to drive standard in a White 9000 with a "monsterous" 290 Cummins and a 13 speed when I was just a youngster at my friends father garage. My left foot is on the floor 99. 9% of the time between shifts and when letting it out from a stop it is a quick and smooth operation. ie no slipping. I think if a guy knows how to drive a standard it'll last a long time. Something I've gotten into the habit of though is taking my foot of the clutch pedal at stop lights, from what I read the needle bearing we have for a pilot bearing is somewhat of a weak link so if the clutch is engaged the bearing is idle and not being used. Just my 2 pennies worth.
