Lever or Diaphragm Pressure Plate

[travmarks]

Hi All,
I'm in the process of doing the rear main so i figured go ahead and have the flywheel resurfaced and put a new clutch kit in. I ended up buying a kit from Oreily's with lifetime warranty...for about $120. My question is that the pressure plate that came out was a diaphram type and the new kit has a lever type. The salesman said the lever type is better...more heavy duty. Is he right...what do you prefer? My truck is a 68 flatbed F250 with 240 and 4 speed. Couldn't find much in the search for this exact topic.
Thanks,
Travis

Factory clutch should have been a lever type.

if I am not mistaken the diaphram type has more clamping pressure

According to http://www.competitionplus.com/03_25_20 ... univ2.html the lever type can have additional centrifugal loading.

And yes, the master parts catalog shows a lever-type pressure plate. RockAuto has several kits of either type.

everyone says the lever type is better.
