This one is for the Boss 528BBF build. The clutch is rated for 800hp and is made to accept the 1-1/8x26 input shaft size of a TKO 600. They are of course available in other options.

Both discs are organic and the pressure plate is a diaphragm piece, so this makes for a very streetable clutch kit without chatter or bad engagement characteristics.

Due to the anodized adapter ring, the RST will fit any pressure plate pattern. I have this one bolted to an 11" pattern with 5/16" ARP pressure plate bolts.

mine uses 6 5/16 bolts to hold the P/P to the adapter instaead of studs like the new one.

I'm sure you have installed those before,but just an FYI make sure the bottom disc floats under the adapter/mid plate,about.020" clearance. Mine was too tight and I pulled my hair out trying to get it to release until I called McLeod and they sent me some shims.
I shimmed under the 3 straps and now it works great.

how in the world ORGANIC applies to a clutch disc I don't have a clue....I guess asbestos is about as organic a friction material as you can get, does ORGANIC in clutches mean non-metalic or a non-synthesized non man made material unlike Kevlar?

just FYI, in chemistry, organic generally refers to carbon containing compounds. Anything that is or was alive can be called organic, including gasoline.... "Organic" clutch discs are usually alot more mild mannered than metallic compound discs.... Hope this helps, John

BTW... Asbestos isn't an organic compound..

Something to think about, Tell the next tree hugging prius owner you see eating a nice organic meal you can make their salad even more "organic" by drizzling a little 90 weight gear oil on it, Just a thought, John

LOL, that's funny, one of the Facbook pals says this...

"Tinzy Smith commented on her own status.
Mmm had my first ham and clutch dust sandwich of season!"

(She does the clutches on Cale Aronson's Ford Pro Stocker)

Normally a non-sprung hub will transmit a little more noise and vibration, but these RST's are pretty low key...
