Flexplate - How Flexplates Work vs Flywheel 

Summit Racing can I put a flywheel in place of a flex plate on a 97 jeep grand cherokee 4.0 42re

Mitch T i was thinking the same bro...lol

Mok4200 😂😂😂😂😂😂

i was thinking this and loled that one of the top comments was this observation

She took it up the flex plate..."groan".

+Jack Karie, Agreed, if you can push it with your finger, it is most likely cracked and in need of replacement.

I called your customer support number (as mentioned in one of your posts). I couldn't have spoken to a more rude person. The fellow on the phone was completely impatient to answer my question. My question never completely made it through without a specific answer before the phone call ended. However, I purchased another engine (I had a bad engine bearing) and the flexplate flexed just as much as the previous. This is on a 2004 Dodge Caravan 3.3L engine, not a race car by the way.

Shit you are right! It was annoying as hell!

Haha she sounds like some cali broad

Driving me up the fucking wall

Steve B , The starter ring gear is part of the torque converter in Dodge applications.

+gladys knight, If you are certain that the flexplate is making noise. You should investigate further and replace if necessary. Could larger tires affect this? Yes! Those larger tires put more stress on the drivetrain as a whole.

No, there is only one flex plate in an automatic transmission vehicle

Hi Bearded, We need some additional information from you. Can you give our tech line a call? 1-330-630-0240. Thanks for watching!

Look on the engine their is mostly a code

The Litterbug Almost. Now it's mostly handled by the torque converter.

All rotating mass is to be considered when balancing. The flex plate is much thinner than a fly wheel, so sometimes they balance with weights on the torque converter.

Hi Mike McCarthy, The Torque Converter body itself is not supposed to grow, but due to the transmission fluid pump pushing fluid into it (under pressure) and its internal operation with increasing engine speed (also creating pressure) propelling the vehicle, the converter must be allowed to float back and forth on the input shaft of the transmission. This is a minute distance but we must also consider some crankshaft endplay as well.

Thanks.....

Actually run of the mill flexplates are relatively thin so they will flex some,more on the outside of the circumference than in the middle where they are bolted,think about it like a old trash can metal lid, bolt it in the middle but you can still move the outside metal around if you pull on it,i had one in a engine on one of my cars for 25 years, when i replaced the engine that flexplate was in excellent shape and it had been "flexing" all that time,guess if your not pounding on it all the time they will last a long time. I actually had a engine built and my builder sent me a scat flexplate like they show in the thumbnail for the video and i never liked it so i went with a OEM one , reason i didn't like it its because as a SFI aproved fleplate (high horsepower certification) it was made extremely thick, i dont think the Queen Mary sitting on it would have been able to bend it any so that right there didn't inspire much confidence and i had heard of broken teeth on these also so i just didn't use it.

The thicker flexplate with increased rigidity and durability is required for high-performance applications with increased rpm capability and higher stall converters and to meet SFI standards for safety rules. The machined flexplate is not for most stock to mild applications. There won't be any problems when you're using the correct flexplate for the proper application.

All we offer for this application is a factory Mopar replacement www.summitracing.com/parts/mop-04800696aa/year/2014/make/dodge/model/journey

+Kumar Nainar You will need a flywheel not a flexplate. For some cars, there are options of going to different weight of flywheel. For example, 1995 Honda Civic with 1.5L engine and manual transmission, there is a 15lb (stock), 11lb, 7lb. 15lb is easier to take off from dead stop than the 7lb but the 7lb has much less inertia, allowing to speed up quicker. How much quicker, I don't know. I haven't tried it. That is what I recall when I was researching. I don't have the car anymore though.

Your tie licence is revoked

alexander jones I don't think so. Did preform a complete diagnosis of the ignition system first?

There could be a lot of Sparks....Not likely the kind that you want ! No....can't affect your vehicles electrical system ! *LET'S GO BRANDON !*

@@Snailmailtrucker Consumed with politics,lol

Triggered CupCake ?

I'd put a 1/8 in washer/spacer on the Flexplate bolt to draw the nose of the Torque Converter back toward the transmission... sounds like the nose of the torque Converter is up against the Crankshaft.

@@Snailmailtrucker i sold the evil wanker 😅

+micheal balma No. An auto /needs/ to have a flex plate.

+micheal balma , Automatic transmission cars have what is called a flexplate and they are already very thin and lightweight.

But why?
