Three Finger to Diaphragm Clutch - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**WorkinLonghorn** · 05-13-2024, 10:33 PM

Ok, I asked about this in a thread that I hijacked but I still need info.

I have a 12" clutch that has the stock type three finger long clutch I believe and it has pretty much ruined my knee driving in this L.A. traffic. I want to keep this truck if I can get the peddle effort down considerably. It was mentioned in another thread that the diaphragm clutch is easier to work. I need to know how much easier is it. The current clutch seems like about 40 Lbs. to depress and that adds up with 300 reps a day for the last 35 years. Any insight much appreciated. -BA
