Hi everyone.
I have a chance to pick-up a Mcleod dual disk set-up with flywheel, pressure plate, and disks. It is supposedly GM but the pressure plate is of the 3 finger type, not diaphragm.

Anyone have experience with this or an opinion? Supposed to have come out of a 55 running a Richmond tranny.

Thanks,
Langg

do the disks have the correct number of splines for your transmission? Would help if you had Mcleod part numbers to verify it will fit what ever you are trying to install it in.

I had the Mcleod Duel Disc and it was not a 3 finger. There is a newer version that uses a stock style Flywheel and I doubt its a 3 finger. If You go to there Web sight You can see what they produce.

I used one of them in my car. It has incredible holding power and works well. You have to make sure the linkage is in good shape and there is enough travel to make it release properly.

I had a Centerforce in my car that held well through the 750'ish HP range....but it couldn't handle 850+'ish. I installed the dual disc and it was fine.

It wasn't great for serious drag racing because it held TOO well with no slippage at all on slicks. I eventually moved to a race style McLeod Soft Lok clutch. But that's hardcore stuff.

I've also used the later McLeod dual disc diaphragm version in a 800 HP 555 in a C3 and it worked well also.

McLeod makes really good stuff.

You might look into their adjustable throwout bearing also. It provides 3 different thicknesses to allow you to dial in the geometry perfectly.

Seller claims its for a GM application and has "fine" spline (26?). Ill verify that before I buy but I really am asking about the 3-finger pressure plate. Is there any problem using one of those in my 75 (ish) vette? (M22 tranny)

No problem using 3 finger. It will take the "short" throwout bearing. Just make sure the geometry of the fork is correct before you plug the trans back in. This is common with any clutch design change. No big deal..just have to get the correct stud/bearing combo together. You might post a pic of it, but the one I had was a "hybrid" where it used a "Long style" pressure plate (like a Ford) and a Borg/Beck style lever assy in it. Worked fine. There are characteristics of the two designs that McLeod combined to make a great clutch assy.

Just to add some...the advantage of a dual disc clutch is it has incredible holding power with lower pressures. That makes for less pedal effort and still be able to hold the power. I never had any chatters or anything bad with it.

Just depends on how much power you're tryin to hold if it's worth the $$$.

Thanks for the feedback. The price is really good and I think I am getting slippage now with the LUK set-up I have (basically stock 11 inch).

Just an FYI. I am running a 2003 version of the original street twin and back then they came with both discs without marcel springs. The newer ones use marcel on the bottom (transmission side) disc. Without the marcel disc, mine was real grabby. Love it now though and it will probably outlast the car.
