Thanks for watching. How many miles have you gone on your OEM Balancer? What aftermarket balancer did you decide to go with? 0:47 Harmonic Balancer Failure 1:44 How To Identify Harmonic Balancer Failure 2:26 Harmonic Balancer Replacements 4:24 Summary

ATI SUPER DAMPER... is the way too go & never worry about it again... Did mine in my garage on jack stands... It's a bugger but can be done...

Nice Vid! POWERBOND = Cheap, durable and so far, mine has held up to 2.5 years of enduring the additional strain of powering a Vortech supercharger.

Yep, the Achilles heal of the c5. Great info....such a good idea on the white mark. I never thought about doing that. thanks!

Excellent video. I also have the Summit version. It also has the best warranty at 1 year versus 3 months for the others. That was a major factor for me.

I went on the cheap and did the Power Bond replacement. So far, no issues. Fingers crossed.

I see a lot of comments saying I went cheap with Powerbond. There is more than one balancer from Powerbond for the C5 C6 LS engines. Cheap one and a good one. Choose the one that fits your budget. Both work but the cheap one has failed again after replacing the stock unit.

Very impressed with the Power Bond Race Series balancer and an ARP crank bolt.

I replaced mine when I had the cam inatalled.. awesome lighting btw

Nice video. I’ll be sure to check mine when it awakens from winter hibernation! Good idea with the white mark.

I had to do it. 2000 C5 with 90'000 km. I took it to a corvette shop here in switzerland. 2500 swiss francs. But I didnt knew that there are balancers like the ATI. I went with the OEM 🤦🏻‍♀️

I can see my balancer is beginning to wobble. I am going to put that white mark on and monitor it. By monitoring I'll see if this is necessary now or later. I would like to know what's the advantages with the aftermarket models? Other than the 6-8 rib system? I won't be doing massive upgrades to this Corvette. It's already pretty damn fast. LOL Thank you in advanced to anyone that helps out.

I'm gonna have to change my balancer soon im so excited.

fluidampr is amazing too! I put them with the ati damper. They are pricy tho

Great video. My oe was marked. Never showed signs of wear. No wobble. But was chasing a squeeky belt in the winters. New balancer squeak completely gone. Weird how these things can fail in so many different ways.

It's good ro replace on the Fox too, mainly because of how old they are now 😁

Excellent, Dave. I have a '99 Corvette, runs great, but I'll check out that HB! Excellent videos, thanks! - Scott

56,000 on my 03. I’m 3rd owner not sure if any of the previous owners had replaced it. I’ve got the white paint mark on it, and check it weekly since it’s my daily driver. Belt chirped when I got it so I replaced the belts and pulley on the tensioner. Hasn’t squeaked in the 6,000 miles I put on it. But I did just find that the belt was rubbing on two of the hard lines going to the steering rack. Just bent them out of the way and clamped them to the rack.

I just bought the OEM Balancer!

I am now kicking myself for not going with the C2501. I have the Powerbond SFI and I have no doubt it will outlive the engine. My blower pulley is 8 rib and I can't utilize it at this time.

not sure if it had been replaced before but at 120k with some wobble going on i went ati. good vid man, better throw springs on the list did have one of those break but got so so lucky

Hey bro..looking at the summit balancer but what’s the difference between over/under drive?

Bro, where we're you earlier with this video?! Lol, I purchased the OEM one this spring , install haven't put it on yet , so looks like I'll be shopping at summit, I got few things in my cart already 😀, (install tool, and that balancer, also thinking of purchasing a clutch remote bleeder while I'm at it)

Never had problems with the harmonic balancer on the 86s I had one with 250,000 km on it

ASP is also a good balancer. Mid priced, last I knew, cheaper than ATI, but more than your cheaper options. Good balancer. Reason I don't know the price? I put it on over 10 years ago. Running a 25% underdrive on a built LS7 in my C5.

nice will upgrade on my corvette

Some people will use OEM on restoration Vette or some Particular C5 editions. Is ok to use OEM but you have to check it after some miles. Is a great advice, if this thing fail it can be a horrible scene. My 1998 C5 have 60k a no wobble jet. But my brother 24hr Lemans c5 was starting to wobble it just have 38k miles.

Nice job on the video..very informanitive

thanks again for a nice video

I replaced the OEM Balancer with an OEM at 11200 miles on my 2005 C6, The new one started to wobble after 1500 miles. So now I go for an aftermarket balancer.

The statement about about no rhyme or reason for OEM balancer failure says a lot about this guys understanding of the word "harmonic", and his understanding of this parts function. The oem balancer is tuned to cancel a stock engines destructive harmonic vibrations. Obviously, on a non stock engine, the resonance frequencies are changed, and the OEM part, which contains polymer , not rubber as the video states, will now be the incorrect part to damp destructive harmonic distortions. with any aftermarket balancer, the damping frequency range is needed for the part to work correctly. The new part might be improved in every way, but unless it is tuned to dampen the particular harmonic vibration of the application, unchecked harmonic vibrations will hurt parts, typically the crank bearings go first, the crank follows if nothing is repaired. selecting a part without addressing if it is tuned for your needs, as when putting a racing tuned harmonic balancer on a stock engine, is as uninformed as running racing slicks on the street.

Just curious did you pin your balancer to prevent from possible spinning.

Have an 03' C5 Base convertible. 15k miles and want to know if it is worth a preventive maintenance swap out.

Nice video, how long and how labor intensive was it to replace?

Thanks for the info! Any chance you'll be selling merch like the shirt in the video? Not a big fan of black shirts.

Quality & powerful info as always brother 👍

Hey man great video, i just ordered the c2503 for my 03 AE. The difference was the under drive. My car is totally stock and i asked if it would throw off my timing or anything and he said no it just gives little more power to the drive train and such. Please tell me i didnt make a mistake.

Thumb 👍thank you

Next fix for me

Mine went on my 91 at 160,000 km

I'm about to order my new damper and was wondering about the whole under drive pulleys. Should I have one installed on a relatively stock LS1?

That summit 8 rib will NOT work with 8 rib boost setup.Ask me how i know.... Had to go with Innovative 8 rib

Will it cause a bad vibration when you give it gas?

I was quoted at $350 labor only to replace the HB? San Antonio, Tx. Anybody know of a Corvette shop cheaper and with trustful quality labor?

How much will it cost to get a shop to do this for me?

Mine failed at 18,000mi on my 06 corvett

what number on powerbond ? but i thinking to go with the c2501

What is the best bolt to use on a new HB? I have heard that people use an ARP bolt or something like that, but most of the things ive read focus on the actual HB brand, not the bolt.

I don’t think any aftermarket one would last 15 or 20 years the Oem one don’t start to fail until they get old and on top of that every aftermarket ones weighs 2 to 4 pounds heavier than the oem one I was on the phone with Summit racing for about 45 minutes and we went over just about every damper they had for my corvette they were all a lot heavier Even the guy I talked to on the phone said he would go with the OEM one too. Oem $100. Aftermarket Ati one $450

My summit C2501 arrived today and it has a slot in it. I bought the pinning kit, do i still pin this like the OEM? or is there another process for the slot?

Had a Chevy dealer replace it, less than 1000 miles later... The crank pulley is falling off !!! 🙃🙃🙃

2:52 Damper, not dampener.

GM needs to send their engineers to a material science class

Did you pin yours???

Mime is making noise. 2000 c5

A fluidampner and ARP bolt.....dont accept anything less 😉
