i was wonder if anybody out there has any luck finding an aftermarket hi performance clutch for g56 with a dual mass flywheel? i am a little worried about switching to a regualr flywheel.

any help with this would be great, maybe some input from you guys that already have upgraded solid flywheels

thanks

I e-mailed Dan with the same question. He promptly replied that they didn't have anything. That was many months ago. Our dmf's are nearly silent and aside from lack of holding much over stock power they work great. A beefed up dmf for us quiet cab guys would be great. I too read of the increased gear clatter even with single disc aftermarket clutches.

I 2nd talking to Dan. Ive got a DD so I have plenty of vibrations and clattering. :lol3:

I dont know of anyone offering a performance clutch for a dual mass flywheel that fit's your trucks.

Dump the dual mass flywheel and go with the SB conversion kit!!!! MY OFE is the real deal as far as towing a trailer goes!!!! SB makes other clutches also that may suit your power needs!!!:thumbsup:thumbsup:beer

the dmf is crap! I had one in my 02 ford it sucked and now in my 07 dodge and it is worse! Trust me get rid of the dmf! As soon as dan comes out with his street DD I'm getting it! Hopefully in the next few weeks!

im not worried about cab noise, although less is better. my real consern lies with the vibrations and the alum. case. the trans bearing sit in an alum. housing and with more vibrations may cause the bearing seats to loosen over time.

i am installing a brand new g56 and would hate to tear it apart in 20-30 k miles, thats why i want to stay with dmf. if someone could tell me that this is not an issue it might ease my bad thoughts!!

 

[nick03]

I didn't have that issue at all! I used my truck for 40k with a Feramic clutch! No vibrations and I sled pulled, boosted launched, towing, etc! I beat that clutch up hard and I was pushing 506hp and 1047tq, so I would not be concerned. Jmo

Dave,

Not much can stir the pot like a good DFM debate. The DMF has had a bad rap since it hit the 7.3L trucks and we could discuss it here for a long time. You are not wrong for being concerned, but it will be tough to get data or autopsy reports on other installations.

Just curious, why are you replacing the trans? I do not know how you use the truck, competition, hot shot, daily driver etc.

1. The Ford 7.3L design has several features in it that the G56 DOES NOT have, like a torque limiting clutch pack. The typical 7.3L design can have over 120 parts down to the rivet.

2. Failure modes on the G56 DMF vs. the 7.3L design do not share very much in common, different designs and manufacturer.

3. DMF's are an advancement in Torsion Damper designs to further reduce engine created gear noise in the transmission.

4. The G56 went all the way in clutch complexity in my opinion. DMF, Self Adjusting Cover (SAC) and a torsion damper disc. About the only thing they left out is an internal slave cylinder.

5. Ford 7.3L up to '97 were all built with DMF's. In '99 when the truck was debuted as the Super Duty, they dropped the DMF in favor of a 13" solid F.W and a very large (but initially troublesome) dampened disc. For this entire series, the trans has been a ZF with alloy cases.

6. For the entire clutch aftermarket, one of our most popular sales has been DMF to Solid F/W clutch conversion systems. The sales are, well, very strong. IF conversions were impacting transmissions, the sales would not be there.

It is a subject of significant debate, but out powertrains were designed as a system and any change can impact the system, most all are considered positive, some have compromizes but what do you want your truck to do and how do you use it?

 

[devolver]

im replacing the trans. because one of my syncros grenaded and took a whole bunch of internals with it, including the case. so i opted to go with a new one.

i dont drag my truck nor do i pull any extreme amount of weight, although i will be hooked to a sled once or twice this year. this truck is my DD and i just want it to hold up for the long run instead of coming apart again.

if the general opinion is that the solid flywheel will be ok then i will go with that because stock clutch set up is not working

 

[GCroyle]

Sled pulling is brutal on a clutch. It's quite a challange, transmit torque, high RPM engagement at a taller than normal gear, hooked to a load that's gonna get ya no matter what, an angry Cummins up front, more BTU's than you want to know about in the clutch envelope to dissipate.

Enjoy your pull.

Get rid of that POS DMF ASAP!! I have an 07' and it would intermittantly not go into gear after start up.Shut the truck off and restarted and it was ok,pulled the trans and found 2 broken metal pins/dowels sheared off from the DMF and they would intermittantly cause the clutch to only partially engage.Upgraded to South Bends DD 3250 setup flywheel,cluch(2 disks)pressure plate,throw out bearing,clutch fork,and hydraulics.More pedal effort,noise,and shift effort but it will hold up!!

If your gonna hook once in a while....

[HarkinsTransport]

The only thing I can say is I ONLY tow with my truck!! No dumping clutch,racing,or sled pulling!! That's an honest , no BS fact!! If the DMF did that for me I can only imagine what it will do to people who abuse it.There was a TSB for hard gear engagement but with over 36k on the odometer DC basically laughed at me when I asked if they'd cover it.I had 41K on the odometer.Made my mind up NOT to buy a factory replacement!!Updated or not I DON'T TRUST IT!!!

 

[07dodge]

If you want a aftermmarket clutch there is no since in putting one against that dmf. Put in one of Dan's solid flywheels and put a fluid damper on the front. I hear that the fluid damper takes away any added noise of the solid flywheel. Thats what i am doing to mine this winter.
