The Stovebolt Site Forums The Shop Area Engine Shop 11" Clutch options

I am trying to decide on the clutch to use for my 261. This unit will be well built and will tow a camper. I am going with the 11" clutch and there about to be about a million options that fit the GM flywheel.

I have used Kevlar several times on other motors with good results but have never used anything other than organic with a 216/ 235/ or 261.

Does anybody have some thoughts on the brand and materials they used? I am set on 11"

Thanks.

Everyone will have a different opinion and you're probably going to hear at least a dozen of them. I vote for Exedy and LUK in that order. Some of the rest of them have been just good enough to make a vehicle driveable long enough to find a buyer for it. Particularly the pressure plates. Some of those are junk. I'm using an Exedy currently on an 11 inch flywheel. Get the flywheel surfaced or at least checked by somebody who knows what they're doing. Many of the 11 inch flywheels were used pretty hard in their time. Finding one without hard spot problems, cracks, etc isn't easy.

Is your 11" Exedy a stock organic disc or something else? Do you know where Exedy clutches are made?

I am leaning towards kevlar on one side and ceramic on the other. The last version of that arriangment we used was a Zoom Perfomace clutch on AMC 401 and it held up to HEAVY pulling for years.

I have read that Zoom clutches are now made in China which I am not a huge fan of.

Try contacting HR Clutch in Bensalem PA. They have been in business for eons. The built all of the Scheiffer high performance stuff for Hurst when Hurst was in Glenside PA. They are really good to work with, can rebuild or build anything, to your specifications or their recommendations, or sell you something new if that is what you need. They have been rebuilding my clutches and pressure plates for close to 40 years, including a decades old scheiffer unit they redid for me a couple of years ago.

It is a heavy duty organic. Some are made in Japan, some in Mexico but mine was made in the USA. One of the reasons I bought it. I've also used Sachs and have had good results with those.
