    I am replacing my clutch soon and would like to go with a heavy duty one. I would like to know if someone is familiar with Centerforce. I've been told that the more heavier duty you go, the harder the clutch becomes to push and keep pushed down. Who has used a Centerforce Stage II or double disk and what are your opinions on these or any heavy duty clutch?

    I have a Centerforce II and have not one bad thing to say about them. I like to do the slow stuff like rocks and the clutch is easy on the foot and it'll last for a while, price isnt that bad either.

    I dont run a centerforce but the clutch I have is a dual friction type, similar to the centerforce, just made by a local clutch company. Deffinatley worth it, especially behind my Big Block!! Pedal force is no more than what the stock clutch was before.

    I have heard centerforce and Ram are the best 2 out there. Everything else is just a copy of theirs.

    I have a centerforce dual friction and it works great.

    Ok... this is probably stupid but Automatics have clutches also right? If so is the an Automatic clutch the same as a Standard? Can a Centerforce be used in an Automatic? Thanx

    The only stupid question is the one that isn't asked.
    An automatic uses a torque convertor in place of a clutch and pressure plate. The torque convertor allows enough slippage for the motor to continue running in gear and stopped.
    The clutches in an automatic are a completely different animal and are used to apply and release the different parts of the planetary mechanisms inside the auto. This is how the different gears are acheived.

    So in short a 'centerforce' type clutch cannot be used with an auto.

    I have run Centerforce before in some hi perf cars and they are excellent.

    Chad BTW... if you were looking for good clutches for an automatic I strongly recomend the Reybestos Blues for anything such as a daily driver or street setup. I have them in my freshly rebuilt 700 ( and have used them for quite a while in numerous vehicles) and they are great.

    i think you are thinking of the clutch packs in the trans, but in a way yes they have a clutch, several of them in fack. but they have a converter (as stated above) where the clutch is on a manual trans. at low RPM the convertov multiplies tourque by about 3 times. ( this is on average).

    Centerforce clutches are designed to grab hard without the hard pedal presures. That is with they use centrifigual force...
    I would reccomend either centerforce or Hayes

    I use the Centerforce Dual Friction. I have a manual linkage on my 83. The pedal pressure increased every so slightly. I dont notice it anymore. It works great.
