Thread: Clutch disc dampening springs

Tweet

Does the amount and size of dampening springs in a clutch disc make a difference? I've noticed the fewer the springs the larger diameter they are.

the amount and size of any thing with springs makes a difference---from maybe wrist watches to rock crushers

What Jerry said. The springs in a clutch hub can make or brake a good clutch. Generally the heavier duty a clutch with a heavier pressure plate load, the hub spring pressure rate is also increased to avoid unwanted chatter or jumping during engagement and disengagement. We've put a lot of dual disc clutches in that are rigid and driving them gets old quick.

I still drag race with a solid hub, drop the hammer on yellow, then just pull the handle. Don't need no silly springs unless you're on the street..... McCleod's web site explains clutch hubs quite well, if you still have questions after that they have a group of very sharp techs to handle most any question you can come up with. Next thing I put a street clutch in I'll use their dual disc with a lite 'wheel; no chatter, no huge pedal pressure, with mild heat it will hook and launch just a bit this side of a Soft Lok!!!!!

You will develop a large left leg

Nope, with hydraulics they're an easy pedal... Even with linkage they're good on the street! McCleod also offers (drag racing stuff) a button, valve, and solenoid that let's you "set" the clutch in the same manner as you set the brakes and hit the line lock button, then hold the button in, let it go on the yellow!!!! Huge changes in clutches and discs with all new materials.... The double disc pedal pressure is about the same as the old 10.5" Mustang clutch now!!!!

Now, the Soft Lok I use for racing, well that one will build you up a good left leg!!!!!!!!!!!!

clutch hubs have springs, and discs are made fromt hings other then sintered iron? whoa????????????????....................lol

Sintered iron and rigid hubs suck on a 7200lb truck driven on the street. Hydro or not. If you don't believe me, call when you're in the neighborhood and you can come drive one. Haha
