ok, i got a 2005 regular cab Gmc Sierra with the 4.8L V8 and the NV3500 manual 5 speed transmission, I have a few moods install maybe 3 or 4 month ago like stage 3 cam long tube headders, street tune with hp tuners, i got this truck as a second owner in 2007 with 50,000 miles and never change the clutch, she has now 173,000 and yesterday my clutch went out, gone. Can someone point me in the right dirrecction of a good, affordable clutch i was thinking stage 1 or 2 the most there so many out there but not good reviews... Thank you!!!
