I have had three, only 2 now. The first lasted for 10 years. This is not behind a 600 hp engine, its worse than that. A measly 350 to 400 HP 440 in a 4x4 truck that I forced to pull 3rd gear when I needed that wheel speed to climb X hill. When blasting dunes I would slip it like you would a dirt bike to gain RPMs. Truck pulled every year at least! twice. Generally abused it every time I drove the truck. So what finally did it in .018 dish in flywheel hot spots on flywheel the size of golf balls. NO! It pull started fully loaded 18 wheeler,RVs and tree stumps.n It gave up one day just a normal day like every other day. It was a daily driver to boot. SO I bought another, thought 10 years was good service. I have one in my duster it only makes 400ish HP its 422 ci. Ive dropped the clutch at 5000+ in 2nd it just boils the 28 inch bfg drags through the 3.23 gears and TKO 550 trans. I WILL NOT ENDORSE things that perform poorly.. The CF DF is one of the best products I have ever used.
I had tried stock NAPAs one pull toast. I got serious I called Hayes, they said street truck and pulls got just what you need a ceramic disk used there F/W & T/O bearing. It chattered violently P.O.S.. I called them to return it they told me NO and nothing was going to do what I wanted with out some issues. Called C/F they guaranteed me I could return if it chattered,if it wouldn't hold they would make it RIGHT. I don't know if they would have? because its every thing they gave there word it would be. This was back when C/F was just starting out not many dealers. Thats why I am a repeat customer.
There are some set up issues though. You must have enough free play for the centrifugal weights to travel after engagement. Free play at 3500+ rpm. The fingers reach out towards the T/O bearing if they dont have room to continue out you do not get full benefit from the weights. Oh I went with the corvette sized clutch and aluminum flywheel in the Duster for quicker shifts and revs. Very satisfied.
Good clutch and happy hide boiling.
