Clutches these days

[throttlehappy]

What are people using these days for a cammed LS1?
I have used the search button but there doesnt seem to be alot of recent threads plus I havent been on the forum for about two years.
Current clutch is an X Grip that is rooted. Ive been looking at the NPC Copper Mix, Exedy Sports Tuff Cushioned Button, Mcleod RST etc

Monster stage 2, been a great clutch. Had it in about 2 years, only a little bit stiffer than stock and no shudder etc... Been giving it a good hammering at the drags this year with no slip.

Ok cheers, ill have a look because I dont know anything about them

OEM, on a cammed car its fine. I think the LS7 clutch is the standard for the LS1 now anyway, if not then I would upgrade to that as a Maximum. A cammed LS1 isn't putting enough torque through the drive train to bother the factory option.

i believe you can get it rebuilt for around $650 ? with the new XX material or up to a Z grip at the same price

Horse feathers, the standard clutch lasted 7 or 8 months for me with just a tune

Standard now is not standard 10 years ago when LS1s were being installed. A "standard" clutch is now an LS7 clutch (all clutches supersede to them - just like all lifters now supersede to LS7 lifters). This clutch is being used in current SS's as well and they handle tuned/bolt-on 6L's fine (which coincidentally put out about as much power as a mid-cammed LS1).

Yeah I have thought of that but everything else needs replacing also so I may aswell get a whole new clutch kit. What is the new x grip material? Does it still carry on when taking off? I swear clutch websites have some of the vaguest product descriptions.

Yeah righto, I was refering to std ls1 clutch not ls7

Ok i must baby my clutch then. As i made mentioned above the replacment is a ls7 clutch.

oh by the way my ls1 clutch has lasted over 100000km of which it spent its life at the drags, giving it a hard time side stepping the clutch driftjng the car, oh and riding the fcuk out of it pulling my 20ft fibreglass cabin cruiser out of the ocean. Oem did ok for me

I've run an NPC copper mix for 3.5 years on a Turbo LS1.

Very smooth.

Only street driven, not at the drags.
By the time you get the clutch, flywheel, alignment tool and delivery you'll be at $1450 at least.

Rebuilding might be good if dollars are tight.

Cheers, I spoke to someone about that clutch today. Looks pretty much the same as the exedy sports tuff cushioned button but the exedy is cheaper

[SASLS1]

I installed a Mcleod RST twin disc clutch, and Mcleod flywheel behind my L76 6.0l VZ about 8 months ago. Clutch pedal is as light or lighter than stock, and really smooth. Works perfect with the factory slave. Compared to my

stock clutch which was slipping really bad at 80000km, so far hasn't missed a beat, even after installing a Tru Trac shortly after.

I bought them new from the US, straight off ebay America, shipping was really cheap only like $60 each, new clutch (6912-07) was $720 US, and I found a brand new Mcleod flywheel (460530) for $150 US, normally $300 + US

and shipping was again only $60. They took over 3 weeks to turn up, I bought the clutch and the flywheel from two different places, and they both turn up on my door step, on the same day.

All the other twin dics clutches I was looking at in Aus where $2000 +, not going happen...

The RST clutch is rated to 800hp, and the RXT is rated to 1000hp, only difference being the different discs, the rest of the clutch is exactly the same.

Here's a good overview of the RST and RXT direct from McLeod.

You can get them faster than 3 weeks, just have to pay more on shipping. I went the cheapest shipping option at the time.

While the gearbox was out, I replaced the engine rear main seal, pilot bearing, the gearbox extension housing seal, installed new OEM flywheel bolts, new OEM slave and aftermarket braided clutch line and remote bleeder line. Also installed a rip shifter, and replaced the trans tunnel OEM rubber boot which was torn. Do it all at once....

BTW the T56 is a heavy sucker, I weighed mine once it was on my work bench, 66 kg with no oil...

I put the RXT with ali flywheel and the Mcleod billet slave in mine.
Best one Ive had yet.... (had 9)
all direct from USA

[Angeldust]

about 4 weeks ago now i got a new OEM clutch for my VZ ls2.

Total cost for clucth, flywheel and slave was ~$1700, then add labour to that.

Well, we'll see how long it lasts..

[throttlehappy]

I got the RST and a Yellaterra flywheel. I still cant believe how good it is, chalk and cheese compared to the old x grip I had

How times change. I can remember a time when if you said anything other than Tex you'd be attacked by all and sundry.

Did you end up sourcing it locally or from the US.
