LS7/ LS2 clutch in an LS1?

Subject pretty much says it all.

Will a clutch for an LS7/ LS2 equipped Corvette fit or work in an LS1 SS?

Thanks

Re: LS7/ LS2 clutch in an LS1?

Having just surpassed 100k miles on my stock LS1 clutch, I've been wondering the same thing. I'm also interested in the LS9 clutch (as I have plans for power in excess of a stock LS7 someday). Does anyone know if these are compatible?

EDIT: I just found that Katech makes kits to upgrade to the LS9 clutch. They're not cheap -- the LS9X kit is a couple hundred dollars more expensive than the McLeod Street Twin, which is one of the most expensive and highly regarded aftermarket clutches out there. The LS9R kit (another 100+hp of rated holding power) is a couple hundred dollars more than that.

The 2001 and 2002 Z28s and SSes came with the same clutch used in the LS6-powered C5 Z06 (405hp). I wouldn't automatically assume that the LS2 clutch (rated for the 400hp LS2) would be any significant improvement.

From everything I have found online and feedback from members on other forums the LS7 clutch should basically just bolt right up. Worst case I may have to shim it a little to get the pick up point somewhere that I'm comfortable.

At this point I'm not convinced that my clutch is bad. I still have a strong feeling that the slave or master are at fault. 31k miles and 11 years of clutch dust has solidified and is making the pedal stick imo. I'm going to replace those with new units the same time I install the clutch and flywheel.

I'm running the LS7 clutch in the GTO. Swapped in with no problems. It replaced the stock LS6 clutch which is what you should have.

Correct that's my understanding. The SS came with the LS6 clutch installed.

All LS1 M6 cars in 2001 and 2002 came with the LS6 clutch -- Z28, SS, Formula, TA, and WS6.
