New Clutch Needed?

[slade8200]

I just took my car out after sitting all winter and when I got on it from a stop taking a right turn, when I hit 2nd, the clutch slipped quite a bit. The car only has 33k on it so I'm not sure why the clutch would be bad. But supposing it is, I'm not sure which one to get. Does anyone have any recommendations? I don't need some super clutch, just something maybe a little better than stock.

How did you get your car out so soon. I'm in NW Jersey and we still have snow on the ground. I too have an SLP SS and my clutch started giving me trouble at 30k. I have some mods and the LS1 clutch does not handle that very well so I went to an LS7 unit and it works great.

We still have snow on the ground, but it just rained the other day and washed the salt off, and today was sunny and dry, so I figured why not. I don't really have any mods, so who knows.

I just picked up a new LS7 clutch (24255748) off ebay for $300 and they are good for 500-600 hp.

Ls7. Clutch from Gm parts direct and a tick master cylinder parts should cost you right around $1,000-1,100. In parts for everything. Nice set up. Good clutch feel

[slade8200]

The LS7 clutch includes what, the disc and pressure plate? I just looked at the LS7 clutch on GMpartsdirect and it was $213... not bad at all. I was hoping to spend no more than $400, but I have no idea how much 'good' replacement clutches go for.

What does the tick master cyl. give you over stock? I'm assuming this is the high-dollar item since you said $1000 and the clutch is only $200.

That's a good price. Just did mine last summer it was something like $375+. Tick Mc is adjustable and is $325 and needs to be installed with the new clutch and is 10x better than stock.www.tickperformance.com, there is a speed bleeder line that makes bleeding new clutch a breeze. Clutch comes with flywheel & pressure plate. You should replace bolts(ARP),pilot bearing, slave cylinder, rear main seal plus fluids. Some problems with the stock MC. sticking and flowing enough fluid, there is a drill mod that can be done on the stock one. This is just a suggestion on what has been a tested set up that has worked for many on here. Seems like a lot of $ but if your changing it on a 13- 14 yr old set up sometimes money spent is money saved

I also recommend the LS7 clutch kit. I ran it for a long time, only reason I'm not currently is because I have more pwr requirements

What Jeff is sorta saying is that since you're already working on swapping out a clutch the smart money would be to go ahead and do the slave cylinder & pilot, inspect the rear main. If no leaks no need to service. ARP bolts are a good suggestion, but necessary, smart upgrade thought.

For DD driving or mild track use the stock MC is fine, drill mod is helpful BUT NEEDS TO BE DONE CORRECTLY. Otherwise you're looking for a new MC because the hydraulic line only comes with new MC's.

For aggressive driving the Tick MC is almost a most have. IF you are seriously considering a Tick MC for the future AND are going to use the LS7 clutch kit you need to hold off till you get the MC to install at the same time. Tick's MC works well with all clutch kits BUT if you use the LS7 clutch and later on install the MC, it has issues. Something with the design of the LS7 clutch pressure plate as it progresses.

The Tick Easy bleed line is worth getting whether you get the MC or not. It is a MAJOR PITA to bleed the MC. If you do get a new slave try to get one that is already pre-filled. Makes it easier to bleed.


One more important distinction when shopping for clutch kits - look for torque rating on clutch kits over HP ratings. The two do not go hand in hand. Torque is the more important number you want to look at.

^^^^^^thanks Scott that is what I wanted to say however I was on my phone at work and every time my boss see's me typing something he says we better get going and I can't type on the move.....

Careful on this eBay number for that price you are only getting the pressure plate and housing the complete kit with new flywheel is $455. The part #pkc6ls7 on gmpartsdirect.com is $430.99, #15046288- slave-$121.76,#14061685-pilot bearing-$12.14, #89060436- rear main-$14.37. That's $579.26 thus far plus at least $60+ shipping due to weight. If you choose ARP bolts another $50 for both sets(arp-134-220,arp-330-2802, summit) if not arp I would at least replace with factory new....so you are just south of $700 for a LS7. If you choose a Tick MC & speed bleeder $375 more + fluids your @ $1,000
Hope the part#'s help and not trying to scare you off from the LS7 it is a great up grade if you plan on Any Mods in the future. I would at least plan on $700 to do the basic swap. Not sure the Stock Ls1 would be much cheaper. Could be wrong

Thanks for the info. Do I need the new flywheel?

[SMWS6TA]

for the ls7 clutch yes. IIRC you need the LS2 flywheel to work with the LS1 crank. That is what mine was.

[Too Fast]

Yes you need the new flywheel for the LS7 clutch. Also, with the low mileage you might not have to change the master cylinder.

18 months ago I had my manual trans rebuilt, (at about 122k) and had the LS7 clutch/flywheel/slave cylinder installed. I bought an '01-'02 style mc 8 years ago, and did the drill mod then, and still would have the occasional problem with the clutch pedal.

The people at RPM transmissions assured me I won't need the tick mc with the newest slave cylinder, and now I have 130k on the car and they were right. Not a bit of problem ever with the clutch pedal staying on the floor. My only regret is not going with an aluminum flywheel, but they convinced me for a street car I would not like it, and at the drag strip it may even slow down the launch somewhat. Yeah, sometimes I drive the hell outta Too Fast, that's what she's built for.

[slade8200]

Thanks. My clutch fluid is absolutely black so I'm going to flush it out and see if the clutch / shifting feels any better.

smws6ta, LS2 flywheel?
