is it worth the risk of buying a used twin disc to rebuild?
ts,
that question is like the classic "i'm still on stock block" statement. We all know there are some monsters on stock block like 580wheel. But we all know that motor will blow if tq is above 450 someday soon. Same goes for the triple with brutal tq and unbuilt transmissions.
by getting the shep trans/tcase you have the larger bolts/new synchros etc. and it will handle more tq period. but all this will do is allow you to use high tq for longer than the stock transmission will but unfortunately very high mileage cant be had on the triple clutch due to the brutal amount of stress. you cant have your cake and eat it too scenario.
If anybody is going to post on here and say they have a car that is over 600 wheel tq and no transmission failures, no driveline parts needing replaced and no rebuild for over 40k miles with a triple I'd be blown away. if you use a twin with your setup and produce more tq the worst that will happen is your clutch would slightly slip, but your trans/tcase are crisp and well protected. That is the whole intention of getting the tcase/transfer case rebuilt. It was to further improve what was there but it doesn't "CHange" the whole engineered concept behind it. most reliable combo/built trans/tcase/535lb tq max clutch.
i have seen 2k miles and the discs need rebuild and 35k with a triple. But the 2k miles was on an abusive track environment. I'd assume anybody who "needs" a triple will drive the car like a bat out of hell so the clutch wont last as long as a twin driven with tq below 535 tq. plain and simple. The triple should read "only use if necessary" lol
IF we all had tons of cash and can afford to "play" like a race team we should all get triples and break our necks on the streets and track with 780ft/lb tq. but that's not how it is for "everybody" It is for some. they can overnight a shep dogbox if they want with a snap of a finger, not me.
mullen,
I just put the clutch in lol! just get a rebuild kit and old clutch and youll be fine. also, exedy measures at flywheel
look at this older thread that has some folks who hate on the triple, some who just randomly said screw it and went triple just cause it holds more and one guy mentioning how a transmission died in 1 year.

side note for amusement:
the clutch is special to the driveline/transmission. they are paired together in mind. The tq for the sl65amg is 738lb/ft stock and a mechanic i know at mercedes told me failure point is near 850 lb/ft. Sooo. what kind of system is that?? $$$$$$ that's what. its a different component period. we're talking 850lb/ft failure for stock. all transmissions are not created equal lol

mullen, yea i hear you man. just make sure u get measurement of how thick the flywheel is because if its too thin you may need a new one. i would only get used twin if only the flywheel is in good shape since the savings wouldnt be worth it. new or used ur trans/tcase will thank u. let us know how it goes man
But if you are planning on getting 50k miles and street driving and expect no stress on your driveline you're mistaken. I got no problem with ryu, you might just want to tell others the minus side of the triple instead of pushing it as the same thing as a twin but has another disc. not the case and jon/shep/mitsu can back me up lol

broham glad to see it worked out and is nice a rebuilt for ya i knew the clutch was straight from jump street i just knew it needed a rebuild ended up buying another one and rebuilding it and dropping it in after my exedy carbon had a less then steller outing for 580 miles and could not go in high rpms without slipping. I was soooooooo close to giving you your money back rebuilding it and dropping it in but i was like a deal is a deal ill find another one and do it did not want to hender your game after you were excited now to list this other clutch for sale once i get pics

ryu, i respect ur info and research and experience but all i did was share mine backed by mitsu tre and shep. anybody can listen to wat they wish. so lets nicely end it here. any more and ill bust out marshmallows to make smores from the flames
alot of great info both ways, i have talked to 3 shops and all 3 seem to be biased towards the triple...i would love for the car to make 600hp but i also want to enjoy the car and im beginning to think 600 is going to be too much ...enjoyment is my main factor at this point seeing how the car has sat for 2 years with the exception of the shootout this year
Feel free to flame away. Smores would go well with this cold weather.

but once there and done thats when the fun begins and you can chill and have fun and watch others builds and remember those down days haaaa
I say no I got a great deal on a hks twin pro and after I received it and then couldn't get parts for it they were back ordered from hks japn so I just ended up going with a stage 4 competition clutch
