It’s no secret that the latest generation of slave cylinders GM has been putting in their performance cars have drawbacks. While the newer slave cylinders did much to alleviate some issues the older units had they actually have a much more severe issue to deal with.

Many of the aftermarket companies are blaming the entire bearing assembly for failure. Upon research, we’ve discovered that the bearing itself isn’t the issue it’s the plastic piece upon which the bearing rides. This piece, when hot enough, disintegrates and causes some pretty catastrophic failures. This not only kills the slave cylinder, it also almost simultaneously kills the clutch in the process.

Here is a perfect example of this issue that happened to a Gen 5 Camaro. In this picture you can see the black plastic bearing support got too hot and failed causing the release bearing itself to eat into the support until it melted to the center part of the slave assembly. After this happens the clutch will not disengage because the release bearing will not move, also in this case it melted the internal seal causing the hydraulic fluid to soak the clutch assembly and cause it to fail as well.



This is the exposed plastic bearing support that retains the bearing on a new slave cylinder.



After discovering this weak point of the slave cylinders in all manual trans C6,C7, Corvettes, Gen 5 Camaros, 1st and 2nd Gen CTS-Vs, and G8 GXPs we developed a billet steel replacement for that plastic bearing support. The OEM on the left and the new billet steel on the right.



This simple upgrade not only takes the weak point out of your OEM slave cylinder it also has tighter tolerances then the OEM piece which helps reduce the amount of bearing movement that is typical at high RPM shifting and rapid gear changes. What does this mean for you? A dependable hydraulic system that doesn't require you to re-engineer the system and measure for setup height, etc. like the aftermarket replacements out there and still allows you to actually abuse the vehicle at high rpm without failure.


Another added bonus is that in a few years when your slave wears or the clutch is getting a replacement, simply remove the billet support from the old slave and reinstall on the new unit!

If anyone has any questions just let us know, this unit works with every single aftermarket clutch available as well as all OEM clutches! It's a MUST HAVE for anyone with these types of slave cylinders!

Sigh... every time a new "smart" engineer goes into a car company they make the same mistakes their parents did...

Dear Auto engineers;

You need to start taking history lessons. Just because you came out of university and have a new degree doesn't mean you should be ignorant to the past. This should have been steel since day one... They knew this for ages and there is a reason that even a T5 transmission swapped from aluminum to steel for the bearing retainers.

Ordered mine this morning to go along with my LT1-S clutch for my c6 Z!!

Can this be used on a Tick Performance Adjustable Master Cylinder ?

EZ SPEED

Awesome I need to order one of these for my Z06....I had this exact same failure pictured above in my 2010 Camaro a couple of years ago!!!

0SNL/MonsterClutchCo

Yes, It can be used on a slave that you are also using the Tick adjustable.

Let us know.

I guess you must be too new to know about the term "cost reduction".

As a retired supplier, cost always wins over experience.

Apocolipse

Oh I do know price reduction and "sustainability"...

The vette is still "mass produced" but things like this hurt a company when the word goes around.

"oh ya just another typical chevy"

This is another example of GM to keep you spending money because they know the part will not last long.

How much time is involved to replace this unit as a preventive measure?

Or do I wait till the oem one fails.

Not a DIY type under the car.

Twinscrew

You should do it when the stock clutch or slave fails as you have to pull out the torque tube to get to it..

0SNL/MonsterClutchCo

The actual swap its self is very easy. However you do have to remove the entire drive-train from the clutch back to get to it.

Just keep in mind that if the slave does fail it will often take the clutch with it, do to fluid contamination.

Thanks guys.

Just wanted to post a picture of what can happen to the original bearing support. This picture was recently posted by "rpmextra" after he had a hydraulic failure. This was the end result.

Bill Curlee

HOLY CRAP! Another THING to worry about! The LIST, just gets longer and longer!

Its on my list of cool thing that you have to have!

Jeebus, I need this asap.

rpmextra

LOL yup ran a little too hot at the track from hotlapping but I needed the seat time and had the best coach helping me so it was totally worth the failure.....I'd do it again lol. The slave was brand new OEM installed June by me. Now I feel confident at the track the monster billet bearing support will help my slave hold it's own. Super easy install by the way.







Thanks Monster

At what temperature of what part causes this failure? What activity is causing the heat to build up enough to melt the bearing support? Was the car modified and if so in what way?

Bottom line was the car being used as it was designed to be? (Yes GM designers know that Corvettes are going to get raced)

I am trying to determine the need for this part. Clearly the factory part is sufficient for typical driving but how much more?

Before anyone knocks GM engineers and "bean counters" remember that better is the worst enemy of good enough. If a cheaper part will do the job then it goes in. Just like a Rochester 4bbl carburetor.
