I just replaced a three finger with a Mcleod diaphragm type and don’t like it at all. It is soft for the customer but it releases different than a borg and beck style. I removed the center spring and it is soft but as you release to the top, it releases too quick. It like the ratio is wrong for a mopar. It is smooth and has no chatter but that’s all I can say. I’ve got a customers car coming in with a Centerforce brand and it was hard to adjust it to not ride on the throwout bearing and have the pedal correct. I’ll work more on it when I tune the carbs later next month. I called Mcleod tech and described the problem and said that was the best I could adjust it because it was it not designed for the mopar. I’m wondering about a twin disc for my next clutch but they are pricy.
This. Unless you want to re-engineer the clutch linkage so you're not driving a toggle switch, use a Borg & Beck plate with a newer disc. Run the plate load at 2400 pounds and drive it.
A diaphragm is for birth control, not a clutch. People evidently don't know that the diaphragm is not new. It wasn't that cool back in the 70's.
