    Ok guys and gals i have a clutch question... my 79k30 is manual sm465

    when its built (which may be a while) and ready to run around and use, i want to be able to pull a sled at the local sled pulls with it, will a LUK Progold hold up to this task? or do i need to go heavier?

    Just from personal experience,I'd go with Centerforce on this one.

    While I don't have much experiece with Zoom's drag clucthes, their regular stuff ($200-$300) is junk. I've had 2 go belly up within 1000mi.
    I'd agree with the others, the Centerforce Dual Friction would be my choice, I've yet to make one slip.
    Also note that Centerforce Clutch discs are made by Luk, in most cases. If you look at the stamp on the disc, there's a litle 'Luk' stamp.
    I've not tried any of their new DFX clutches, I've always been happy with the dual friction version though.

    When I needed a clutch for my 95 K2500 with a NV4500, I called dial-a-clutch. I exaggerated and told them I ran a built 406 and towed 8K regularly and 10K occasionally, and the salesperson told me that a pro-gold would be overkill for my application and that a standard LUK repset would be fine. I think that a Pro-gold would work just fine for your app. The LUK is also quite a bit cheaper than the CF, at least it was for my app.

    The centerforce has an advantage with the weights that help lock it stronger the faster your engine revs, that is why it's better.
    Hence the name :D ( from centrifugal forces )
