Anyone know the difference between the GXP clutch and the Camaro clutch?

[99-LS1-SS]

I've heard that the Camaro clutch is the same as the Z06 clutch. There is no way in hell the GXP clutch is that good. It's too weak for the power and weight of the car.

[Greg@PacePerformance]

The Camaro clutch IS the same as the LS3 Corvette and LS7 ZO6.
Sorry I couldn't cross the GXP parts over. Maybe Paul can do some checking and come up with something.

[99-LS1-SS]

Thanks Greg. You just gave me all the info I needed. The GXP got screwed on the clutch.

As greg stated, the camaro clutch is the ls7 unit, the gxp clutch... Not so much :(

Maybe the understatement of the year! As we like to say around these parts, it so weak it couldn't pull a greasy string out of a mule's ass! :D

Andy, has anyone thrown mid 500's at the Camaro clutch without much issue?

Info lifted from another Forum.


"All VE V8's use 92161753 flywheel, pressure plate and clutch plate as an assembly. L98, LS2 and LS3 VE's, including HSV's, all use the same clutch."

However

"Listed for W427 LS7 are the following...
12571611- flywheel.
24248985- pressure plate and clutch plate."

So there's a difference between LS3 clutches and LS7 clutches used in Australia.


"Holden Service Alert No 2962 says that VE clutch issues are due to the self adjuster sticking down on worn serations, this means it over adjusts and makes the pedal stay down and causes the clutch to slip."

[Greg@PacePerformance]

Paul,
You have a part number for the slave cylinder on the W427? Is it the same as the VE's?

Edit:
Might as well post what I PM'd Brandon yesterday since this thread looks interesting.
The GXP flywheel only comes with the clutch and pressure plate.
92161753 - 1120.75
GXP clutch & PP - 92161754 - 135.43

Greg,

Is the flywheel the same for the W427 and the Camaro?

[Greg@PacePerformance]

Yes the same flywheel for both.
I would say as long as the slave cylinder is the same it would be an easy flywheel and clutch swap for an upgrade and many more options.

No I dont have info yet on the W427 slave, I'll look into it.

14th Sept 09
"Holden released a Techline today relating to this issue.
At this point, it only relates to 8.5, 9 and 9.5 model year V8's, and involves fitting a different clutch kit to the 92161753 or 92067954. It also MUST have a different design pedal assembly fitted, or the new clutch will fail. The problem is premature wear to the self adjuster mechanism of the clutch. Model year 7 or 8 (not 8.5) will be dealt with later, as some different parts are required."

"They were NEVER going to fit 427 clutches as a replacement.
Holden were redesigning the 92161753 kit for VE, and in the interim, were approving the fitment of the 92067954 VZ kit.
The redesigned 92161753 has now been released, but we are waiting on the pedal fix for the full cure."

[99-LS1-SS]

Sorry about being confused Paul, but are you saying the LS7 clutch won't work with the 2009.5 LS3?

[Greg@PacePerformance]

Interesting Paul,

92067954 is the 2004 Corvette LS1 Flywheel, Clutch and pressure plate

[Crazy Paul]

Nope not saying that at all.

As far as I know the LS7 clutch will fit any L series but you must also use the Corvette LS2/LS7 flywheel 12571611. The Y LS2/LS7 flywheel has raised risers on the outer rim that most other flywheels dont have.

Yes a real step backward. They must have been desperate for an interim replacement while they solved problems.

[Devilish34]

Andy what did you do to Dave's(Blade) car ??? I know there was a clutch upgrade to handle the added power but what else??

So the teeth will line up fine with the GXP starter? I'm sure they will I just want to make sure.

Yes.

(The W427 cars actually rolled off the Holden production line with LS3 engines and LS3 clutches fitted, HSV removed the LS3 engine and clutch and installed the LS7 engine and clutch into those cars at their workshop).


Once you install the Corvette LS2/LS7 flywheel everything fits fine.

Note the 6 raised pads on the LS7 outer flywheel rim. ( LS series normal flywheels dont have that). The pads are needed for fitment of the LS7 clutch and pressure plate.

You rock CP! Thank your for the lesson.

[Crazy Paul]

Can't find a W427 specific slave cyl part number.
The number for all VE V8 clutch slaves is 92190612.

[99-LS1-SS]

Paul, since you are the master of parts pictures, is there anyway that you could get a picture of the LS7 clutch compared to the GXP clutch?

[Greg@PacePerformance]

That is a good thing Paul. That means HSV didn't change that part and you are correct when you said you can use and LS7 clutch if you change the flywheel also. :woohoo:

[99-LS1-SS]

How much better is the LS7 clutch than the POS clutch that my car has?

[Greg@PacePerformance]

Going by the pictures Paul posted I would say about 50% better, and you would have many aftermarket options available also.

[Crazy Paul]

Sorry I dont have any pics of the LS3 clutch in pieces.
I only have pics of the LS3 engine and LS3 clutch assemblies removed from new cars by HSV which were turned into W427's.

You can tell by looking at the fingers in the centre and at the outer rim of the flywheel that the LS3 clutch here is different to the LS7 clutch.

Thanks Greg. That's kind of what I was thinking. I can't decide if I want to jump in with both feet and get a Spec stage 2+ or 3 clutch or step up some and get a LS7 clutch.

[Greg@PacePerformance]

Here is a better picture I found on Ebay for the GXP clutch.
Put it in your picture files Paul
