If you can find out who makes the napa clutches you may have a good kit there as long as it isn't chinese crap. A Luk clutch kit is where most people land here on a street driven car, as they are the OEM supplier. The flywheel is heavier on the replacement kits, so do some searches for threads on it. Some people say you can't tell and others say "it's smoother". The important part is to put in quality parts, as it's either very time consuming and hard work or very expensive if you pay a shop to do this. Read as many threads as you can - about balancing, parts choice, etc.

This is a great price on an aluminum flywheel setup, with the same pressure plate and disc as above.

I not trying to hijack the thread, but if the LS7 clutch is used does the application require shimming the throwout bearing

No not needed

Exactly. Unless you want to change the engagement point more towards to top of the clutch pedal travel. But no matter what, you should always measure to be sure, even if your reinstalling oem parts.

For as much work/money (if you are paying labor) I would spend the money and get the LS7 clutch or a good aftermarket clutch. It is an absolute pain in the *** to change a clutch in a C5.

How about full LUK LS7 replacement clutch kit with flywheel for $239?
It's $227 on RockAuto right now, and shipping is about $10 so similar price to Amazon.

Ls7 will be my 1st choice when the time comes

Just curious as to why the ls7?

Chillo32

A lot of people use the ls7 because it can handle higher horsepower applixarions. If your c5 is stock or just some bolt ons, the oem clutch is more than enough. If you have boost etc than ls7 or aftermarket is a better route. I do know a few people that have installed the ls7 on their bolt on c5 and weren’t happy. Heavier clutch etc. It’s always a dangerous road to go down of using products that weren’t intended for your car. Unless you have a highly modified car or you have a specific reason for changing, there is really no justification for using anything but a stock clutch. My car has 125k and I’m on the original clutch. Not sure what an upgrade to an ls7 clutch would get me. I’m pretty happy thus far.

Speedy007

because the ls7 has a higher hp rating then the ls1 mostly!

Chillo32

like I said. Everyone is always in search of bigger and better. If you know your car, most of the time oem is more than enough.

Speedy007

not for my application oem c5 isn’t enough! Also Since I can remember the stock c5 fails to give me full pedal pressure after it detects your getting on it. It levels out to to a 1 1/2 inch push for a minute or two after returning to normal driving operation. Good for speed shifting not good for trying to stop and take off again oh it’s a little touchy! Wonder if anyone has managed to shut off this via hpt. I would only assume it has to with some vacuum pump somewhere. Or ideas to solve it. I did the ranger thing like 4 times already!

And what are you running sir? 750 cordes air to water boost? Lol

Speedy007

both you may look up my build it’s on here

Speedy007

Link?

Chillo32

Pick up your phone. Call cordes performance racing and ask for Brian. Thank me later. And stop atting me.

Speedy007

You merely were digging into what I was running but anyways it’s cool don’t make me part of your ruff day!


Slow Vette complex apparently!

Chillo32

like I said. Oem clutch isn’t right for boost. So not sure what you’re adding to this conversation other than flexing your ls1. Lol.
