Are "Heavy Duty" Clutches Overkill?
 

Looking to put a new clutch in my '72 C20 with the stock 402 mill. I originally had a Borg & Beck lever style years ago and yanked that stiff POS in favor of a diaphragm style 12". Are to "HD" diaphragm versions that much harder to push? Are they more prone to chatter? Just stick with the stock spec one?

Thanx!

Diaphragm are much easier to push and have the same amount of clamping force as the borg/beck style. Much easier on the linkage and your knee

This was my experience w/them as well w/the caveat being a higher end diaphragm vs. lower tier cheap stuff.

Are you doing anything with the truck that would abuse a regular clutch? Any towing, heavy loads, off roading? If not then I would use a quality factory replacement clutch.

Are you currently having clutch chatter problems?

If getting a full-face organic material disc, you won't have chatter. Puc type disc material (ceramic, Kevlar, etc) are more aggressive to hold more power and clutch dumps but are prone to chatter.

Replacement OEM type diaphragm clutches from companies like Valeo, LUK, etc will be fine

It never chattered or slipped. Once in a while I put my big ol’ 11-1/2’ Lance camper on it to go camping or tow a 16’ trailer to the lumber yard but it’s just a daily driver. Honestly, when I had the clutch changed out years ago I am not sure what the shop put in it but it was definitely easy on my knee and I had zero issues with it in over 12 years. I know they put in a raised diaphragm clutch. I am yanking out the clutch because the T/O bearing is toast.
I just bought a Luk clutch kit and I will see how it goes.

I second the Luk clutch kit.
Used and rebuild are junk.
Luk seems to the only reliable clutch manufacture left.

Good Luk! ; )
