Clutch Shortage…UPDATE!
UPDATE: The LS7 Z06 clutch is installed! Now check this out, while the clutch "kit" was back ordered, the individual components were available! So I bought the kit piecemeal and received it in about 6 calendar days. This clutch is wonderful. There is a little smell and heat, but it seems to be dissipating quickly. As someone posted, the clutch engaged close to the floor, but after only 50 miles I can feel it start to come up a tad. Also, I no longer have driveshaft rattle (I'm not sure what aspect or components of this repair contributed to this, but I welcome the change!)
In addition to the clutch and hydraulic components, I added a Katech KAT-A6503 remote bleeder covered with a DEI 10403 Remote Bleeder Heat Sleeve, and Dorman 935-101 12mm Drive Shaft Couplers. The original couplers were not cracked but the rubber had hardened.
My 2004 is on the rack with the driveline out for a clutch hydraulics re-do, and we discovered a new clutch is called for. I want to upgrade, but only a step or two. Stock engine m6 now, some plans for 400+ in the future.
I have looked high and low for a LS7 Z06 kit and a McLeod Street Pro 75157 kit. BUT HAVE FOUND NADA, ZIP…. Scoggin -Dickey says 2-3 weeks and McLeod 3-4 weeks. Trying to stay in the $600 range, but geez…

A touch over $600, but my buddy has one of these in his C5 and it's fantastic:

Good luck! So many things are on backorder and it's getting old.

I think every clutch out there has someone who's had a bad experience with it, but I cannot recommend Monster for QC reasons. It does drive very easily, of course.
How much over 400? 400 is fine with LS6 clutch.

Watching closely as I will be in need. Always wanted to try the Monster Twin disc.

Rock Auto has the LS7 clutch/FW kit (Luk 04-905) for only $260 + shipping and it's in-stock: https://www.rockauto.com/en/moreinfo.php?pk=4695798 https://www.rockauto.com/en/catalog/...lutch+kit,1993
They are usually very quick about shipping. Also you can save 5% off with coupon code 18151755877710012
Highly recommend this kit, it's what I've been running for almost 4k miles / 1 year on my '01 Z06.

Unless you are making north of 450 HP at the engine, the LS6 clutch is the one to use, the LS7 is good for higher HP. Also the LS7 clutch weighs more and causes many to have a stiffer pedal.

Lots of LS7 clutch fans on the forum, both from GM and LUK. Common notes are that the flywheel has more mass, so a tad less throttle response but with a corresponding resistance to off idle stall; the need to measure the throw out bearing to clutch finger space is more critical; pedal effort may be slightly more; and that pedal engagement will be closer to the floor at first, working back to nominal over a short period of time.

News Update! On a hunch, I called Scoggin-Dickey back and found that while the "kit" is out of stock, the individual components are IN STOCK, so I went ahead and ordered the LS7 components on that basis. While I was at it I also ordered a set of Dorman torque tube couplers from Tick Performance. The shop is also changing out the slave and master cylinders, and adding the Katech remote bleeder.
If you can afford to wait a few weeks the McLeod seems to be a good option for just a bit more money. I considered the LUK alternative but some bad reviews on the condition of the delivered parts--and my gut--said no bueno.

I'm thinking about headers, good street/daily driver cam. So....maybe 400-430 ? With a set of 3.90s or 4.10s that should wet my whistle. I'm retired, drive about 3K miles a year, and don't do burnouts or race. Probably 90% of my driving is below 60 MPH, so I don't care about top end. My 1000Hp racing days are behind me, but I would like going through the gears in a spirited, but non-violent way.

I bought my OEM clutch via gmpartsdirect. Only took three months to arrive. Or was it four? Wait so long that I seriously contemplated canceling the order to get an in-stock clutch from someone else, until I re-read the restock fee and policy. It's huge, and that the part is nowhere to be found has no effect on that. I, for one, will never, ever, do business with them again, and recommend the same to others.
