[QUOTE="weekendwarriorfsw32, post: 565942, member: 771"] 2008 with 144,xxx miles and I have spartan tunes on it and anything above the 40 hp tune and in 6th gear it will slip. Also every once in a while when shifting the clutch petal will only come back up half way and you have to take you foot and pop it back up the rest of the way then after that it's normal for a while, is that a slave cylinder going bad? Only company's I know of are South bend and Valair. Who makes a good all around clutch, This truck will be around 450-500 and all its getting is International coated pistons and possibly Tow powers, studs, and some other little misc stuff. Keep in mind this is just going to be a towing truck so what clutch is out there that you guys like? [/QUOTE]
