Centerforce Dual Friction

I just ordered the Centerforce Dual friction clutch yesterday, and im having second thoughts because i was reading a JEGS catalogue and it said that the centerforce I and II clutches maintained a stock clutch feel, and it didnt say it for the dual friction model. Now im running a stock L69 5 speed - 190horse 240TQ, did i make a mistake buying a clutch that is made for a much more powerful application?

resurface your flywheel before installation, Install per directions
and enjoy! I ran one for a long time and the clutch feel is like stock . Its a excellent street/strip clutch.

basically what i am looking for is a clutch that is better than stock, but feels stock, money isnt a problem - ive been saving long enough that i can spend it - so what is better for my setup Centerforce II or dualfriction??

again money isnt a problem and i already ordered the dualfriction - should i just install it or exchange it... am i over reacting?

The D/F is just a better performance clutch. It has centrifigal weights on the "fingers", that spread out as the engine accelerates. These "fingers" are said to help put more pressure on the plate, giving the system more clamping force, leaving it less likly to slip. For your app. it is fine, youll like it. Leaves room for the power upgrades too. The other two just are not as strong as the D/F.

It's a little sticky, but it's definately well mannered enough to get used to.

Did you follow the manufacrures recommendations and "break in" the unit by driving easy for 450 miles? If you dont do this you will have problems. Everyone has their own opinion. The only problem I had was when I tried to get it to handle 500 flywheel H.P.. With my old 357 combo it worked fine, at least for me. After that I had to step up to a SPEC Stage III.

I've had 2 T-5 CF DFs in my 83, and I currently have a T-56 one in it. All with stock hydraulics. The T-5 ones spent most of their life behind a fairly healthy 400. They have all been absolutely flawless. Smoother and lighter pedal than stock, in fact, when driving around town or something; but they hook up hard at high RPMs. I've never had one slip.

I wouldn't let what you've "heard" scare you off. I've "heard" too, that the Earth is flat. Fortunately my hearing it didn't make it so.

I suspect that alot of the problems that you "hear" about are the result of improper installation or break-in. The product itself can work quite well, if the correct procedures are followed.

my dad just bought one for his cyclone project. it is going to a top loader with a 600 horse 460. this was the only clutch recommended to handle that power. it definitely shouldn't hurt a stock setup at all. if anything it is well prepared for a life ahead of it.

Anytime you use a friction material, you have to break it in. Whether it's disc brakes, drum brakes, or a clutch.
Centerforce clutches are also extremely sensitive to having everything centered and straight. You will shear off the rivits if you don't set it up properly, and if that happens, they won't honor the warrantee.

Follow the manufacturer's recommendations and you shouldn't have a problem. The weights also save leg fatigue.

Although it could have been put in better terms, I have to agree. Mine isn't any better than the stock clutch.
