Dual disc clutch recommendations?

[69hugger]

It is time to ditch my T-56 trans & LT pull style clutch setup and upgrade to a Magnum and dual disc clutch. This is behind a 502 based big block with a 1 piece main seal. My engine is internally balanced. It has 700 ft/lb. of torque.
Having heard great things, my thought was to use a Centerforce DYAD, but Centerforce tells me they have no flywheel for the 1 piece seal crank that is internally balanced.

The only twin disc setup I have found is a McCleod RST clutch. They can offer either an aluminum (my choice) or steel flywheel. Then there is an adapter ring that bolts to the flywheel to mount the dual disc setup.

I am looking for any experiences with the RST clutch setup, good or bad, or any other options I have missed.

Thanks in advance for any help!!

Monster LT1-S if they have the flywheel you need. I do not know if they do anything for big blocks, but I loved this clutch behind my LS-based engine. Uses GM disks and pressure plate from the C7 LT1, has the holding power you need, and is a very smooth stock-like feel. I never had a problem with it at all.

That isn't the exact setup you need, but it's where to start looking. Give them a call to see if they have what you need.

I couldn't be happier with my RAM clutch. Best dual disc clutch I've ever used in any car for street and track.



Give them a call and see what they can do for your combo.

Put a McLeod in my Cuda just recently behind a 6.1 HEMI and t56....... and at idle, out of gear, with the clutch out its loud as hell...... sounds like rod knock.... talked to Bowler and McLeod and they both stated "yep... thats the way they are..... no spring , so the plates tend to vibrate and make noise"... WTF? Its brand new and $1300, so I'm kind of stuck with it now.... my only hope is that it gets better as it gets broken in.... fingers crossed

After a little more research and talking to Centerforce, they DO have a dyad for my setup. As they are supposed to be quiet, are only a little more than McLeod, and look like a very stout setup, I am pretty sure that is the way I’m headed.
Thank you all for the input!

I strongly urge you to check out the new tilton street twin. Im very impressed with mine and everything is billet and completely rebuildable.

Been happy with my Spec Supertwin ST trim. Has held all the power i've asked it to so far (1000+rwhp) and friends is consistently holding 1500rwhp.

Drives very well and pedal pressure is not too firm. Does make a little noise clutch out in neutral, but almost un-noticeable above the idle of the car (and my car isn't loud).

RPS BC2 in my Chevelle. It’s pricey, but it’s carbon which means crazy long life. Zero chatter and it’s smooth as butter. My wife could drive the car easily.

I have a McLeod RXT between my LS9-clone and T56 Magnum. I wish the driven discs had springs in their hubs to help damp some vibration. Other than that, I love it.

This is news to me, about the twin disc making noise. Mines not installed yet, but I do have the Mcloud RXT with a steel flywheel.
What kind of noise does it make? Is it only on clutch in? In between shifts?
How's it just driving around?
I've heard good things about Monster clutches...

Mine makes noise whenever the clutch is in and the discs are free to move around. IE, Sitting at a light, clutch in, you'll hear it. Again my noise is slight, i wouldn't mistake it for rod knock like mentioned above.

I have a Centerforce DYAD in the Camaro but in my street/track Vette I am running a Tilton ST-246 Cerametallic. I have heard really good things and track proven with near stock feel when coupled with their 6000 series TOB.

Yeah I'm still dealing with my noise....see my other post in the transmission section..

My noise is with the clutch OUT....in neutral at idle...... which seems to be the opposite of what others are having.... makes no sense since the assembly should be clamped together.... the discs and the plate shouldn't be able to move around and rattle or knock

I had the entire assembly balanced by a local machine shop, so now I'm concerned they screwed it up....

I can rev the motor pretty high and don't seem to have a vibration.... its really hard to tell if the noise is there since the motor is loud and the bell is right by the headers etc

Same noise with my built T56 magnum. I have read the noise in neutral with the clutch out is common and normal.

[DRJDVM's '69]

Everything I have read, its clutch IN where it has a tendency to rattle, since the disc and intermediate plate is not compressed against the flywheel, so it has some play in it...

Reached out to Craig Meyer at Bowler again and he is also going to reach out to his contact at McLeod and see what they have to say....

Drove the car today...shifts fine, no noticeable vibration (only went up to around 35 mph since I have some other things to sort out first)...cant hear any rattle or knock but the car is loud and has no interior or windows, so at speed its pretty loud..... cant be sure it isnt there at speed in gear etc

Here are just a couple links on threads where I found others with the same issue.

Very happy with my Tilton ST-246 Cerametallic and Tilton throw out bearing.

My buddy just put an RXT in his coyote swapped fox and T56, no issues so far, he literally just did it this weekend, has about 120 miles on it so far...

Interesting.... I had not found posts about the T56 actually being the source of the noise.... everything I found talked about the MC dual clutch being the source.... but with the clutch pushed in...
Something else to look into.....
