Ok first off srry i havent been on here in awhile guys so heres a recap of whats going on. Okay around 4 months ago i lost the my nv5600. so last week i pulled it to send it to high gear in memphis tennesse after the people at the trans shops around here said it couldnt be rebuilt. Anyway i decided to check out my clutch while it was easy and it was absulutly destoyed ruinded the fly wheel. the springs in the pressure plate had gotten weak and came loose and had rubbed groves on them selves the friction matrial was gone and the flywheel and pressure plate were blued. I do rape on my truck but never ever felt it slip nor did i try and slip it the clutch has about 35,000 miles on it. so im contacting south bend about it now lol. so my question is who else makes a good clutch for high horsepower trucks my trucks makin around 450-500 hp when i bought mine from southbend they said it would handle 550 but who knows lol. if someone could point me in another direction if south bend dont help me out any im not goin back with them. thanks alot guys
