I have one (04-064) sitting on my shelf. What measurements do you need?

You need the 1550 Novak sells.

I did buy mine from Novak. They told me it was a RAM 1550 and sold it to me at their cost. When it arrived it was boxed in a RAM box and had a sticker on the back side of the flywheel that read RAM 1550. So I assumed.

Yes my measurements in my thread are correct. They were taken on a granite slab using a very accurate and calibrated micrometer at work.

Great thanks for the info. I was trying not to through any more parts at it. But I guess I may have to. I talked to a guy and he is going to look at my recorded data (he is not local to me) to see if there is anything that sticks out and then may just try to replace the o2's and see what happens.

AKPrice Has anyone used a bw4401 tcase? I have two of them now and would like to use one in my swap since I wouldn't have to buy a 241 and a slip yoke eliminator kit. I'm also using a th400 with the short 32 spline output and have the correct small tcase adapter. Can't find much info on the bw4401 tcase in the first place. It's a little bigger over all pretty sure it has a vss in it, but don't know if it's correct and it also has another single wire that is coming out of the case that I don't really know what it's for. Any info?

Why are these 2 flywheels not the same height? They should be the same height from the crank mount to the face.

This is the correct flywheel and what yours should look like.

Still having problems

Okay I am still having issues. Still no codes showing up what so ever. Engine runs but runs bad. Seems to have a miss and has a pretty rough idle. Here is everything that has been checked/replaced: New injectors, new plugs, new wires, new intake gaskets, checked head gaskets, and all sensors. I have also checked exhaust manifold temps at the head. The temps on bank 2 (passengers side) are high 200's or low 300's. The temps on bank 1 are all in the low 100's. I am about ready to call it quits on this motor and save for one from Pacific Fab or similar. Here are pictures (all taken with in a minute or so of each other, that I took from my scan tool this afternoon. If anybody has any suggestions I am open 100% to them. Could this be an ecm issue?

Stock 1050 flywheel & 04-201


Ram 1550 flywheel & 04-049
05-23-2015 07:33 PM
chasmosis1 Yeah, that's the main reason I keep coming back to post on this thread......I read all of the posts that say such & such SHOULD work. I will post pics of what I found as well just so future researchers have all of the needed info.

It's the tightening down and the height and circumfunce of the clutch hat that are the issue. I'm not telling you not to question. I'm telling you I paid the money. I installed the clutches. I'm telling you what works. I would have preferred to save the money and the time.

Honesty, the math of the stock stuff on paper looks like it should work. Which is why Novak originally recommended it, but it doesn't and why I recommend different and why Novak changed to recommend different. It's also why all the other threads are wrong, they didn't update to say what actually worked.

My clutch recommendation does work, and it works well. Great pedal feel and no slip. Haven't had a single issue with it in 3 years. And I drive my shit like I stole it.

-Ram flywheel with 04-049 clutch disc......crank flange mount surface to back side (trans side) of clutch disc hub is 1.64.
-Ram flywheel with 04-049 clutch disc/pressure plate mounted down solid....crank flange mount surface to pressure plate flat surface (where the throwout bearing rides) is 3.094

-NFW1050 flywheel (Stock 6.0 flywheel purchased from Oreilly's) from crank mount surface to flat is 1.199.
-NFW1050 flywheel with 04-201 clutch disc (Stock Luk clutch for 6.0) crank flange to back side of clutch disc hub is 2.160.
-NFW1050 flywheel with 04-201 clutch disc/pressure plate mounted down solid....crank flange mount surface to pressure plate flat surface is......3.094.

So looking at these numbers not only is the factory flywheel thicker (and $200 less expensive) than the Ram unit, but the 04-201 clutch disc has more contact with the input shaft spline, and they both measure to be the exact same where the throwout bearing rides on the pressure plate fingers.

Now I do appreciate the input from you Why J?, and I had no doubt in your knowledge, so don't get me wrong. I think that either the oem aftermarket has found that there was a problem, or I have come up with a combination that you may not have tried.
I bolted up an OEM flywheel with and OEM LS clutch and the wishbone hits the clutch hat before the clutch disengages. I have the flywheel and the clutch with the marks on it here on my shelf to prove it.

Maybe LUK changed their LS clutch? I doubt it. Maybe Novak has unfucked their adjustable throw out? I doubt it. There is more to the clutch fitting then the heights.

I think what you will find is the 12" OEM clutch your trying to run vs the 10" I told you to use is the problem. Now when you try to run that 10" clutch on the OEM flywheel is also a problem which is where the RAM flywheel comes in.

But run what ya want.

From what I am reading the 1550 flywheel does not have the extra 0.40 thickness correct? I am asking because you show to use the McLeod flywheel in your thread to end up with 0.40 extra flywheel thickness and 0.60 extra clutch thickness for the total of 1" thickness. Is your throwout bearing adjusted almost totally closed than?

Thanks alot for your help!
The RAM flywheel is no taller than a stock unit.

Yes, I used the RAM for the correct surface area contact with the clutch.

If I remember my throw out is still adjusted almost all the way out. It's been a few years though. But it all functions flawlessly and I have never had an issue with it.
