Flex plate selection

[mopar440cu]

I am looking for a flex plate for my 2001 5.9 diesel 4x4  with a 47RE transmission. I really dont see the need for a billet one and are having a hard time finding a non billet one. The only one I can track down is the one on MTS website. The F2-5.9 for $195. What do yall think of this thing? Do you know of any other non billet ones?

• 3 Times Thicker than OEM
• SFI Rated Flexplate
• Designed to handle extreme duty applications
• Designed to take the punishment of high horepower engines
• 4mm thick centerplate
• Ring gears are precision robotic welded with cold welding process

Rockauto has stock flex plates. I’d spend the extra hundred somethin on a Goerend flex plate before I bought the one you listed. I’d just prefer either stock, or go with the one you know will perform without question, especially when it comes to your trans.

I think firepunk runs those. I ordered that same one, but the fit was sloppy on the TC hub, so I ended up with a goerend billet. Just don’t order a BD.

Thank you guys! Great clip! I guess billet is the way to go then.

More like going with a quality part than cheap part so you not damaging other things like your transmission.

I run this in my truck. They are rated at 500hp but we have people running them in higher horsepower trucks.

Who makes this one? Good fit/finish?

What is wrong with the BD flexplate?  I have a new one on the shelf waiting to go in.

Cracked welds from the factory

So if they Aren't cracked they are ok?

I looked at mine, it Didn't look to be cracked.  The ring gear is the only thing that's welded

[CTcummins24V]

Should be good. Cracked ring gear welds are the issue

Seems weird. Rated to 500? My current trans was built to hold 550-600ish and i was told it wasn’t needed. I did do it just because I wanted everything done but curious as to the rating being what it is compared to stock.

Thank you everyone for the responses!

I have to ask a question about your sig. What do you mean by XZT and DS5? I cant think of it, but I haven't had enough coffee yet! LOL

Mine was built Sept 2017.  According to the tag.  Maybe they corrected the issue

I thought the same thing, being an aftermarket flywheel. Looking at Firepunk's flywheel it is rated as "capable" of holding 1200 HP. However it does have the tangs that showed so much slop in the above video. The goerend flexplate has the circle that fits the end of the crank which seems to have a much tighter tolerance.

 

Looking at the one on firepunks website, the picture has some porosity in the welds!

Chinese made. I have the PRW unit sitting in my shed brand new from Jegs. They dont have it on their website anymore. I couldnt rationalize having to drop my transmission again to replace it, or worse have to replace the TC or input shaft. 

 

Goerend unit all the way. Tight tolerances and they have 12 holes or 2 sets of holes for TC bolts incase they oval from poor installation. I did have to clean some slag off and I touched all the holes both TC and crank with a grinder to de-burr it.

[mopar440cu]

Here is some pics of my flex plate that seems to have the bolt holes wallerd out a little at the toque converter and the crank. lol.I placed a torque converter bolt in one hole to show what I mean. Hopefully yall can see it.
