no the 6.7's have a dual mass flywheel thats the prob

 

How many of the different say 500-600hp 800-1000FTLBS TRQ, Units replace the factory fly wheel??? Have seen A few. And have heard that some of them are far from smooth? Anyone really like theirs??

i dont know an aftermarket company that utilizes the junk dual mass fly wheels other than (centerforce or zoom). Ford went away from them for a reason and the G56 clutches dont hold for crap. They are a very common fail and its irritating that that design was pickup up outta the scrap bin.

 

1SlowCTD.. Good to know.. So what would be your personal recommendation for A strong, smooth one? Thanks.

Sorry. LUKE how has your feed back been on them VAL AIR units been for the 09 Cummins. I am babyin my factory one along here for A month or two. But this sucker is headin out the door ASAP. Thanks.

The new Valair Nodular Sprung Hub Dual Disc's are going great. Much better than the Solid Hub Design.

 

Sadly, this is a very common problem with the dual mass setup. The springs have a tendency to wear rather quickly. We have seen trucks with as little as 10k needing a new clutch and with the addition of a tuner and other go fast goodies it will only enhance the slipping.

The South Bend SDD series have been great sellers, worth taking a look at if you are having issues.

I run the south bend dual disc in my 09, i love it, at first it shifted kinda rough but after awhile it gets smoother, and you can't beat james's prices at rsd

 

I was thinking about maybe a Valair single disc full ceramic??

Thats what i run in my 12v for now and so far its good but haven't done any major launches yet either.

 

I really haven't heard anything bad about valair, but everyone in my area is runnin southbend so i haven't really heard much about them at all. But i would recommend that if you plan on goin with a lot more upgrades, go with a dual disc. If you are just gonna do a few small upgrades here and there a big single will probably work just fine

 

I'll pry wait and get the dd then i'll start with the upgrades. Does your XRT make much smoke out of the 6.7 or no?
