550 Clutch upgrade

I have an 80 550E with 4-1 pods and DJ kit. That's it, but my stock clutch is starting to go. I have replaced the cable and adjusted per the factory, but it still slips at high RPM. What is the best setup to run on the street?

Some people put three HD springs with three stockers? What springs should I use?
 
I think I'd replace the plates. Even though you've made those changes, the stock 550 clutch can take way more horses (significantly over-engineered) so something is worn out down there.

If you want to replace the springs though I've used EBC and they've been fine.
 
I run a GS750 clutch in my 79 550. You want the inner basket and plates. This will add a couple plates to your clutch. I did this swap on mine back in 1980 so the details are not fresh on my mind.
 
Clutch plates are the same for the 550 and 750. 550 takes 7 plates, not sure about the 750.

Measure the thickness of the fiber plates, if they meet the spec in the service manual, you will gain nothing by changing them.

I have a used set of clutch plates that measure up to the new part thickness spec. The standard is 2.9 - 3.1 mm, with a service limit of 2.6 mm. My plates all measure 3.0 - 3.1 mm. I have them listed in the Parts For Sale forum for $25 + shipping. Drop me a PM if interested. Order up some new stock springs and you will be good to go.

buy a complete set of EBC clutch springs and measure the fiber plates.
sometimes you can put in new clutch springs and be ok for another couple thousand miles. however this is a wearable part of the drivetrain so expect to put in a set of fiber plates -after soaking in oil overnight.

gasket too if you cannot save the old one.

I use ebc because they come from parts unlimited and thy are like $8.00 for a set of springs and fibers are like $60.00 a set, but any brand is ok. barnett,vesrah,K&L,Gen.Suzuki, etc...

Those extra plate kits are hard on clutch baskets. The steel & fiber plates are thinner and cause gouges in the basket. Ask me how I know....:oops:

Id stick to stock parts.
 
Thanks for all the help, I am going to get a set of fibers and some ebc springs.
