Comparing stock Hellcat driveshaft to Redeye/Demon drive shaft

[@Demonology]

The weak point on the Demon drive shaft is the middle bushing that can't be changed when worn out, trust me I know. I tried the Carbon fiber drive shaft, I am currently running the aluminum driveshaft from Drive shaft shop, and I am happy with it.

[@b5beast611]

I noticed DSS has a dampened 1 pc. Is that the one you're running?

[@bmasontv]

Very true. The carrier being is a weak point, that said, at my power level, not to mention I'm foot braking it... should be good for a while. Time will tell.

[@reyperez3424]

I purchased the aluminum too from DSS but haven’t installed it yet

[@paulsawitsky9251]

I had a Livernois Racing driveshaft in my 2018 Hellcat. No vibration or harmonics. Also had a 3.09 differential. Great combination. Livernois Racing is located in Michigan.

Great video Professor Mason, I learn alot from you Thank you!

[@deliorendon9494]

I had a 2016 Challenger it would vibrate at highway speed‘s between 75 and 80 miles an hour. With the stock driveshaft I had the tires road force balance also replace the tires took it to the dealer and I had them replace the driveshaft vibration continues. Long story short I ended up trading the Challenger for the charger hellcat I’m happy as hell thanks for the video please keep us updated.

[@reyperez3424]

So you are getting vibrations from the aluminum DS? Now I’m having second thoughts about changing my DS

[@shawne7228]

I was surprised how similar the Hellcat and the Redeye driveshafts were. Hopefully you can stop having to swap driveshafts all the time now.

[@jochenheiden]

And here I was thinking the single piece drive shafts were the only way to go. So what’s with all the hellcats blowing their stock shafts when on sticky tires? A couple years ago that was a big deal.

[@fabianm2819]

thats the centre carrier bearing tearing off, put the track bushings from JXB on it and youre set

[@shawne7228]

So what are the driving Impressions with the Redeye driveshaft? Hopefully nothing. Probably feels stock as a rock now. Which is what we all want a driveshaft to feel like, quiet and smooth, and not broken trying to run a 1.49 60-foot Time

[@bmasontv]

Feels perfect. Smoothe as silk

[@shawne7228]

@@bmasontv now you can really enjoy those 309 gears. The vibration would be annoying.

[@Saiyan4658]

B Mason I think I got a chance to buying a new red eye driveshaft for my ‘16 Hellcat. This is 100% sure a DIRECT fit correct? They said without a good VIN they can’t do a return. So I have to be SURE this will work. I have an A8 as well.

[@bmasontv]

If you have a Challenger it will fit.

[@hemichallenger3643]

Thank you for the clinic. Great info.

[@joshuaochoa9839]

i have a 392 and i already broke a hellcat driveshaft and a demon driveshaft when i accelerated from a launch, why does this keep happening?

[@malamri424]

I've broken 2 OEM shafts on a grand Cherokee SRT (not even a trackhawk). The first time during a hard launch but the second time was just going down the highway although I was at 96k miles at the time. I hope it's not an issue from another component such as the transfer case.

What was your flange to flange measurement

I'm curious to see how that works. Great info! 👍👍

[@glockmodder]

[@BoostedCat]

Is the red eye driveshaft off a charger? Are they interchangeable? Can’t seem to find a clear answer. lol

[@bmasontv]

No challenger and charger are not interchangable

[@BoostedCat]

@@bmasontvmuch help! Thanks.

[@nojdrof]

Great information. Thanks!

[@Saiyan4658]

So many people on Hellcat.org says the Demon/RE driveshaft wont fit the Hellcat because of the transmission flange is slightly different.

[@bmasontv]

Well... my car will have to differ. Lol. Works great.

[@jeffsmystic]

Brian do you know if the Demon driveshaft will work on my 18 widebody Challenger? It looks the the redeye and demon are the same but wonder if I had a demon DS it would fit ok

[@bmasontv]

My understanding is it will. The Redeye is working great in mine.

[@jeffsmystic]

Thanks for that info. Do you know if the redeye DS is vin locked like the demon is?

[@bmasontv]

It is... frustrating to say the least.

[@jeffsmystic]

@@bmasontv very frustrating especially since the Redeye is not limited production.. Boohoo Mopar👎

[@RS3_WAY]

What does that me ? I know yu need 309 to run a red eye what about axles

[@cfm17hellcat11]

Where was the vibration noticed when driving at the cruise speeds you referenced ? ie: seat, steering wheel or????

[@bmasontv]

Rear of the car. Almost like both rear wheels lost the balance weights.

[@cfm17hellcat11]

B. Thanks for the quick reply. I’ve have the single” CV in a M6 Hellcat and a dual CV in a A8. No vibration in the seat on either. I have a slight steering wheel shake in the A8 at 81 to 90. I’m thinking/ hoping it’s time to re- balance the front tires/wheels. Thanks again. Great video as always.

[@ThaDjavi101]

B Mason mine is doing that bad right now. Should I go back to stock? I got the car used and don’t track it just love driving it. But now it’s doing that and I hate it

[@alfonsoledezma2006]

Is the one piece driveshaft hellcat is the same for for Dodge charger 2016 RT ,5.7 hemi?

[@bubberrand]

My Wiles Racing driveshaft on my Hellcat doesn’t vibrate at all.

[@Saiyan4658]

I had a Wiles Racing driveshaft and it started vibrating around 130+. His older design before he changed to the CV Joint design was pretty good. But he stopped making those driveshafts for a reason, many of us had to return ours.

[@kiddwebb9588]

At Wiles run 4" tube with a sonnax slip spline, 1350 spicer joints and sonnax flange yokes now

[@bdogjr7779]

Awesome B《☆》 Revlon :*: I like it :*: Good luck with the Redeye shaft :*: I would love to get the whole Redeye in my garage one of these days🤓☻🤠

[@korvstopparen]

Is this what you need to replace if you get better tires? Also what does it cost?

[@bmasontv]

If you bring the power of your HC up significantly, or you take your car to the drag strip regularly, you may need an upgraded drive shaft. As for the cost, if it is ever taken off the FCA restricted part list, it is roughly $1,300.00

[@rickgeraci2027]

Hey Bro! Once again a great knowledgeable piece of work for us! Being old school mopar (Solid one piece drive shafts) when I discovered that my 2017 T/A SRT had a two piece DS it made places on my body tense and tighten up! So also my car being a stick car this is right up my alley Bro. Hopefully next year will be the N555's, Diff Brace, and a Red Eye Drive Shaft. Am I going to be Ok on OEM new drive shaft length being a stick car? Thanks Bro, Pistol Grip Rick

[@bmasontv]

Demon ds will not work for your car.. a one piece so hasn't been as big of an issue In stick cars from what i understand

[@jesseclifford4970]

When you buy a OEM drive shaft does it come with new bolts.

[@bmasontv]

I do not believe that it does.

[@jesseclifford4970]

Do you recommend putting new bolts.

I have a 2017 Challenger scat pack with an automatic transmission. I did a pull onto the freeway and later on after investigating the noise I found out I lost my carrier bearing. Do you recommend the aluminum one from driveshaft shop or factory? Since they seem to be the only manufacturer that still makes one piece driveshafts for my car. Also I was going to using the bmr cradle lockout.

Thank you for info brother, I've heard the 1 piece carbon fiber driveshaft is the way to go for any higher hp mod cars drag racing. Heard launching 0-60 times were improved.

[@victormarin9229]

Would you recommend upgrading to a one piece driveshaft if I'm going with 20 in drag radials on my hellcat? Stock power.

[@bmasontv]

Here's the thing, drive shafts will typically fail due to wheel hop. So if you're on the street chances are you're going to be just fine. I wouldn't worry about it for a minute. If you will be going to the dragstrip quite a bit, I would say that it is maybe a good idea to get a different drive shaft at your power level, but not mandatory. Just watch that wheel hop my friend

@@thenotoriousnova1102 let out at the first sign of wheel hop. Proper tire pressure and sizing is important. Don't underinflate the tires looking for traction. This will give an inconsistent footprint and can lead to wheel hop.

[@DaDarkninjayt]

So is it really worth it because my center mount that supports the center of the driveshaft failed on my stock 2016 392 and I figured I would send the extra $3-400 for the better durability so I won't have to deal with this in the future but am I loosing drivability in the process of gaining durability?

[@bmasontv]

That's a tough call. Obviously the red-eye Drive Shaft won't work in your application, so it would be a 1 piece Driveshaft for you. It is my understanding that the DSs drive shaft with the CV joints on both ends is a really good peace, and may offer better drivability than the drive shafts with the U-joint.

[@DaDarkninjayt]

@@bmasontv I figured that ,appreciate the insight its been a back and forth decision trying to decide.

Cant run a Redeye driveshaft on a manual. Ive seen enough information on snapped driveshafts doing alot of damage on Hellcats under stock power just on sticky tires to not wanna chance it

[@icehog2367]

Not true that the 1 piece will cause vibration, I have none with a CCI shaft.

[@bmasontv]

True that they are more prone to vibration. No, you are not guaranteed to have a vibration however you will be more likely to have a vibration if you go with a one piece driveshaft. Try this, take your car out hold it steady at about 95 miles an hour then run it up to about a hundred miles per hour and just hold it and see if you get a vibration out of that CCI driveshaft. If you don't congratulations you're one of the lucky ones who got away with not having a vibration

[@eb972]

Once you have enough power you will rip the rubber out of the carrier bearing. I’m on my third used driveshaft. I buy them used from newer cars for around $200

[@MiHiHemi]

Seems to me if FCA thought a one piece shaft was better they would have used it.

[@icehog2367]

FCA used the 2 piece shaft due to the cars ability to go 200mph, the center bearing is key to that issue by keeping sections short. None of the one piece shafts can safely run 200mph, but they're much stronger for drag racing.

[@Saiyan4658]

Hey B Mason, I ordered my new Redeye driveshaft! Do you have the torque specs of the driveshaft bolts?
