Hi guys....need a bit of help. I bought a LT1 T56 clutch from a member on here. Centerforce Dual Friction. Ive been told by Centerforce this is not for a Fbody but for a 94-96 Vette. Can anyone confirm this from pictures?

 

Wrong forum.... LT1 Based Engine Tech is only for "engine" topics. I'll move your post to the "Drivetrain" forum.

 

It looks like a 'Vette throwout bearing...square pull flange rather than the tear drop shaped flange for the Fbody...both LT Fbody and 'Vette clutch pressure plates look the same. The 'Vette clutch should fit the Fbody as the pressure plate is the same design and with the same bolt pattern and the number of splines in the disc is the same. The clutch you have pictured should work in your Fbod.

 

Sorry and thanks!

 

Thanks for your reply. So you think I may be able to use this unit if I change the bearing?

Heres the reply I have received from a technician at Centerforce. I have asked him if it is possible to work but have yet to have a reply. Was hoping for people to chimw in that actually know real world experiences.

"The parts you have fit a 1994 to 1996 Corvette . This clutch will not fit your 1995 Camaro The throwout bearing. The Camaro uses a round top throwout bearing and a Corvette uses a square top throwout bearing. Also, we use a different rivets which hold the straps to casting together."


Sorry for being naieve. In all honesty this will be my first stick car and Im a nervous not knowing anything about the clutch instalation. I do appreciate your info.

 

UPDATE:

"The part number is a DF039130 If the throwout bearing was swapped, the clutch would bolt up and possibly work, however, we machine the pressure plate between the Camaro and Corvette different. The pressure plate for the Camaro is machine for quicker release.."

Im comparing the OEM unit and everything looks the same except the added weights. After reading the sticky on clutches the number stamped on the pressure plate on the oem and on the centerforce match the numbers posted on the sticky. So from what I can tell its just a difference in bearings. Although I am curious as to why the camaro pressure plate and Vette unit are machined differently so the camaro has quicker release? I would think the Vette would be the quicker release. I cant find the
differences... any thoughts?

 

If I had the clutch that you have pictured, I would install it in my Z, square throwout and all. The 'Vette throwout works in the Fbody also. How I know this is that I have a 'Vette style throwout in my car right now and it works. Actually, it is a better design , IMO than the Fbody style. The guy from CF either does not know this or hopes you may buy more parts from him.

 

Thanks! My last question is about the difference in disc. In the oicture the oem disc is shorter than the centerforce. Centerforce says they use the same disc in both camaro and corvette applications.

 

Then the height difference should be no problem. That side of the disc faces the transmission and once the clutch assembly is bolted to the flywheel there is plenty of room within the clutch assembly for that extra height. The weights on the clutch fingers are interesting. Did the person you bought the clutch from describe how it worked in his car and was his car an Fbody? If he/she liked it, it likely should work well for you.

 

I thought that was the engine side as the OEM disc has "ENGINE SIDE" stamped into the disc hub? As for the previous owner, it was never run but was bolted up.

 

You are right about the engine/flywheel side of the disc hub. I had to look at my old clutch disc and it has a sticker that says "flywheel side" on the side where the hub extends out. If the CF sales/tech person says that is what they sell for both 'Vettes and Fbodys, using the alignment tool, try bolting the new clutch in to check clearance between the disc and the back of the crankshaft. If there is clearance that you can see/feel, that means the disc won't be touching the crank and you can then go ahead and torque the pressure plate bolts and continue to re-install the transmission.
