i lost my slave cylinder about 2 hours ago about 45 min from home and turned around and drove home with no clutch. so i was curious if there are any upgraded slave cylinders i can buy? i have heard there are not any for a powerstroke or duramax just for a cummins. i have owned the truck for 3.5 years and i believe im on my 4th slave cylinder. they were all bought from napa. this last one lasted for about a year and a half and i put a valiar single disk in it with hd springs so i think its why i lost this one and i feel if i dont put a better slave cylinder in it i will keep having this problem with this bigger clutch.
