Geezz… the clutch disc again. There are many different perspectives on clutch discs and pressure plates.
I wheeled the heck out of ’85 short bed, 5-speed about 10 years.
I never had a clutch disc issue, like a premature failure, in all my years of owning manual tranny vehicles from my 1967 Vette with an L-88 3200 lbs pressure plate to my current 1986 XtraCab with an M-PACT.
I’ve never run anything except a factory stock or replacement. I’ve had my ‘85 in the sand dunes in Glamis and across the giant sand dunes in Mexico, which is where you can very quickly smoke a clutch, and never had a failure. The rockcrawling guys I know who went with an aftermarket heavy-duty-rooty-tooty disc and pressure plate, like Centerforce, had issues. First, they grabbed and were too sticky – no bueno for rockcrawling. And two, the extra clamping pressures blew out the factory clutch slave cylinder.
I remember in my sand rail days, some guys installed the feramic discs to get more bite, they ended up popping a transaxle – about a 4 hour fix. So they went back to a less sticky disc. If they smoked a clutch at the dunes, they could R&R a new disc in about 30 minutes.
Obviously if you are pumping heavy HP, a heavy duty clutch and pressure plate may be a good choice.
Typically, if you go up in psi in a pressure plate, you will feel more pressure at the clutch pedal. It may or may not be enough to be an uncomfortable issue.
Marlin sells top quality products, so you can’t go wrong with a choice, but it has been my experience after wheeling for about 20 years that a LUK, Aisin, M-PACT all worked perfectly for me.
So I have not experienced the "extra advantage of having a higher rated clutch as in foot pounds" in my Toyota pickups.
