Anyone have a NAPA part number for a Luk ProGold clutch?

I need a 12" one for the 168 tooth flywheel(two-piece rear).


Also, whats the diff between Borg & Beck and a Diaphragm style clutch? /forums/images/graemlins/doah.gif
 
Borg and Beck has the 3 large fingers and the diaphragm style has a whole bunch of little fingers. I find the B&B style has more holding power.
 
Borg and Beck is rough on your left leg but will provide more holding power. I took Rene's advice and put a diaphram clutch in mine and I'm very happy with it.

I have a Napa clutch but it is a Zoom.

diaphragm are bevel spring and the other 2 styles are coil spring IIRC
 
I think with the hydro the B&B should be a little more forgiving but we'll see...how do you like the Zoom?
 
I agree. When I first bought my clutch I had a mech linkage so I went with a diaphram because I knew that my left leg couldn't handle the B&B.

I have a hydro clutch now and the pedal effort is far less than it used to be with the mech linkage, but I still will continue to use a diaphram clutch.

As to how I like it, I've had it for over two years now and it has never slipped, not even once. Not in a mud pit, not with a bell housing full of water....never.

If I had umteen million horsepower I might consider a Borg and Beck, but as of now, my diaphram clutch has PLENTY of holding power for my needs, and I have driven it on the road everywhere, and played in mud, sand, rocks, water, you name it....

One word to describe my $140 Zoom clutch from Napa?

Flawless!!

04-902 for the ProGold
That is what I have behind my BBC and I LOVE it...I had a Centerforce DF behind my SBC and it was a piece of crap...

All the 85-up trucks with the hydro bell use a diaphragm pressure plate. I'd be concerned over possible reduced life (or outright failure) of the master/slave with the extra pressure required for the B&B unit.

The 60-62 Chevy trucks used B&B pressure plates with hydraulic clutch, but the master and slave were both beefy cast-iron units with 1"+ pistons.
 
We had a lot of defective 3 fingered Borg and Beck clucthes come back,especially the 12 inch ones--Borg Warner finally told the parts stores to sell the diaphram 12 inch in its place--dont know if it was a design problem,or Borg Warners mexican rebuilding plant to blame--I blame the rebuilders,because I've seen many original GM clutches last well over 100,000 miles,but many of our customers didnt even get 10,000 miles out of the rebuilts,and they didnt abuse them.Maybe this is why its hard to find a rebiult clutch nowadays,their bad reputation kept mechanics from wanting to install one. The 12 inch B&B is a left leg killer,as already stated--I hated the one I had in my 72 K5,it broke 2 pressure plate fingers in a months time,couldnt shift it or stop it,it refused to disengage.I finally put an 11 inch diaphram type in it,worked fine--and I almost pushed the pedal through the floorboard the first time I depressed it,it was so easy compared to the other type clutch--almost thought there was something wrong it was so easy!. /forums/images/graemlins/crazy.gif
 
Now the flywheels the same between the two types of clutches right?
 
Yes, flywheel doesn't change...both the Borg and Beck and the diaphram style bolt up the same way.

Alright. I'm gonna go exchange my new 3 finger for a diaphragm out of a 87 k5? And it should all be cherry. My hydro bellhousing should be here this week
