TroyK

I believe I have been running on a KY stage 1 for 100k & now starting to slipping. I was wondering if their is another clutch available that is better for daily driving, the KY grabbed to quickly on a normal stop light start. I don't care about price. Also, a GM dealer will be installing it, so I don't want him to get confused if special mods need to be made that his GM book don't mention.

I left a msg on the phone w OTTP, but never called back. I guess I'm looking for a reliable vendor too?

If you only have 315ft lbs of torque stick with the gmpp clutch. It's factory gm and if installed by a gm dealer I believe the install is covered with a warranty in case the throw out bearing fails early. Crate engine depot has a good deal on them. Don't forget the flywheel bolts.

gmpp is stock LNF, right? My stock clutch was way under sized. The dealership installed the KY stage 1 previously. I'm at 155k miles, no warranty.

I'm running the gmpp on my 380hp Lnf and its doing fine. There have been a lot of throw out bearing issues the last few years, some by the guys installing them wrong. The gmpp would be warranted for that if installed by a gm dealer, or so it says on ced websight. It's basically an Lnf clutch but there are slight differences.

I've had my GMPP on my car for a few thousand miles already, and it still holds great. Last time I had it on the dyno was with the factory clutch at 75k mikes, made 334wtq while slipping. Finished the tune on this clutch just street tuning. I'll agree with Nova on this one, if that's all the power you are making a GMPP clutch will be more than enough. If you do get it just make sure to use white bic pens to center the pressure plate on the flywheel, since the holes are larger where the alignment pins go.

Edit: Sorry for the hijack here, but ECaulk if you read this, the LuK flywheel is working out nicely with the clutch. 3k miles so far so only time will tell.

OK, I don't think the dealership going to know what GMPP is, I really don't either. Is that a LSJ clutch? Do we use a LSJ throw out bearing?

The GMPP clutch isn't sold by the dealer anymore.

You use a LNF green TOB...

Comes with almost everything you need, including the right throw out bearing. Just need a flywheel and flywheel bolts as they are torque-to-yield so you can't re-use them.

The flywheel is up to you. The genuine GM parts are interchangeable/expensive, but places like ZZP and LuK offer flywheels for ~$120.
