| Post subject: | What clutch to buy? |
Well I'm in the market for a new clutch and after reading some posts about spec clutches, I decided to give them a call and see what I could find out. I called them up and they said I'd have to send them my flywheel and they would build me something... Um, no. This is my daily driver and I can't have it apart for a week. I've got a 73 Duster with a 833 OD from a mid 80's van in it. It has a 10 inch clutch right now and I like to be able to buy something and swap it out on a weekend. Should I just pick one from here and call it a day? That would be what I'm looking for correct? |

The 10" clutches that Spec shows don't fit the 122 tooth slant flywheels. They fit 130 tooth flywheels. If your engine is stock I'd simply buy a new 9 1/4" Borg and Beck (this is the stock type cover) and run it. If the engine is not stock or you beat the snot out of clutches then read on. Spec knows what fits and has some options, but the direct bolt-in clutches are only about 8 7/8" and unless you get a fairly aggressive clutch they don't seem to have very good torque capacity. I have a Stage III Spec clutch for my race 170 because it's relatively low torque, but high RPM and I don't want a stock cast pressure plate coming apart. I'll let you know how it works in a few months. I also have a Weber clutch cover which looks just like a stock 9 1/4" B&B cover except it has a full compliment of springs rather than 6 of 9 and the springs look to be of larger diameter wire. I'm going to pair this with a disc from Spec to get something reliable for a lower RPM, but higher torque 225. |

Thanks for the info. I should have mentioned that it's a turbo car as of a couple of weeks ago... I'm headed out of town for a week so I'll be able to stew on it, but when I get back I'm starting the process of finding something decent. Could I just get a stock replacement 10" clutch, take it to a trans shop and have them add some HD springs ( I already run a hyd clutch ) and do what your planning for the 9.25 low RPM and high torque of a stock engine with a turbo. |

One problem with the 10" scalloped clutch is that the cover itself isn't very strong. If the stamped cover were stronger I'd say sure, take it to a clutch and brake shop and have them increase the load, but I don't know if the cover will survive. The other problem is the pressure plate itself is gray iron and is known to explode at only moderately high RPM. If you keep it to 5000 RPM or less the 10" pressure plate will probably live with the centrifugal force, but the cover is going to flex with a heavier spring load. The 9 1/4" cover is stronger because it isn't relieved to accommodate the larger pressure plate. I don't know if the pressure plate in my Weber 9 1/4" cover is nodular iron or not, but by virtue of it being smaller it will survive higher RPM with the same strength material. McLeod and Spec both have 9.5" clutches that require the flywheel to be redrilled. It's more money and hassle than a bolt-in solution, but with anything other than the mildest of turbo builds it's what I'd do. |

Really? Has quality gone away? I used to run them behind my built FE's with no problems, but that was almost twenty years ago. The built FE's would break the disk loose around 3500-4000 rpm with the stock stuff, and the pressure plates kept dissintegrating. The centerforce clutches always held up for me. CJ |

I just put a centerforce-II into my Wrangler; I had the PP itting here collecting dust, brand new and bought for something different but it wound up being the "wrong one" I did get it at a helluva deal back when I bought it via feeBay about 4-5 years ago for my original intended app; which it wound up "not" fitting; but when I looked up the number I saw that it would fit my jeep so instead of reselling it I hung onto it as I had no intention of parting w/ my Wrangler. I knew it would come in handy "someday"; this is on a stone stock, 4.0 inline 6 w/ 3.07gearing. well that someday came, I pulled the trans for synchros and bearings and figured I "might as well" throw a clutch at it just because it was apart anyway; I went and bought anew, "stock" disc for it and a T-O bearing, put it all together and the pedal is way too soft even for a hydro clutch; and if it were mechanical I would call it "over adjusted", as I like a release point towards the middle of the pedal travel; thing don't release il it is damn near topped out. I have ~700 miles on it and am getting "used to" it but still don't like it. I mean, it seems to "hold" ok I have not seen any slippage after about the 2nd day of driving it (yes I did have the FW refaced) but the high release point+ the softness (I can't even feel my foot on the pedal and thats with gym shoes on, let alone my workboots) before it was not "overly"strong like the older mechanical Truck clutches but it was enough to at least "feel" underfoot. |

OK, So I'm back from in town and trying to decide on a clutch. I don't want to buy a new flywheel send it to SPEC and have them drill it and yadda yadda. I've been looking at the RAM clutches 98729 Powergrip series 10" clutch. Has anyone used this clutch? ok so tech support got back to me and it is a B&B plate...not a diaphragm setup...hmm |

I'm so freaking confused. I've researched my way into paralysis... So if I run a 10" clutch already... Can I use this: http://www.specclutchsuperstore.com/dus ... 20704.html ??? It says 10 inch for a 273, stage 1 = 425HP. I've emailed SPEC ( waiting ) , but just wanted some more opinions... Thanks |

The 10" Spec clutch does NOT fit our 122 tooth flywheel. It fits the 130 tooth flywheel. |
