clutch info contradictions

[25thZ28]

i really honestly hate to make a new thread for another "what clutch should i buy" question, but it really is hard to decide when every other website you come upon says the exact opposite about the same clutch as the one before it.

so in short...

with my taxes i got a 2 piece rearmain 355 for my 92 Z28. i currently have a 1 piece rear main motor with a LT1 T56 swap.

i'm pretty confident that the RAM billit aluminium flywheel for the 2 piece block is a good piece, costs 406.99 from jegs. have heard nothing bad about that but i'm torn between the RAM powergrip and the spec2 clutch.

both are just a tad over 400 buck, RAM claims theirs has a little bit of chatter, but half the people using them, say they dont have any.

the spec 2 claims to be a smooth clutch capable of holding up to the power i have, but i've heard they are prone to exploding in general.

the motor is has 11:1 KB domes, world sportsmanII heads, monster lunati solid lifter cam and a few other miscelaneous things, am told its probably 450-500 horse.

anybody have personal experience with either of these two clutches, or another viable piece for the same money? TIA

I have the SPEC 2 and yea it's very smooth, no chatter. I've never heard anything about them exploding, lol! Probably wouldn't have bought it if I did. I got it installed back in June and no problems with it.

ram has very good stuff.
there have been some spec issues( ls1) I have noticed that most of the spec issues have occured with the stock flywheel though
I have a spec III xpad and beside the shim issue mine has been great.
Up until the end of this year it held everything I could throw at it. it just started to slip though.

maybe the problems with the spec clutches i read were abou the LS1 cars....something about the springs in the disc breaking and falling out into the bellhousing from time to time.

Oh nice...I didn't need to hear that one either, lol! As long as it gets me thru this summer I won't care.

I recently just installed a RAM clutch on my car and also have a RAM flywheel. I just did this about 2 months ago and absolutley no problems or chatter I am very happy with it all, so my vote is RAM

[25thZ28]

i dont even remember which forum i was reading that was bashing spec so i really dont even know if its a reputable source, thats why i thougth i'd come ask here, and nothing bad has been said about either so i suppose either must be pretty good!

darrenscamaro, which RAM clutch did you use?

Same here!
I had a spec 2 until I had my rear main go out and ruin my clutch.
This didn't happen because of the clutch.
I then went with a Center Force Dual Friction and I like that as well.

Fly wheel, I have a SLP Steel Billet flywheel.
I was going to go with an ALum. piece but when I found out that it would cost me in the initial grunt getting my HP/Torque to the rear wheels so I picked the SLP one.
The Alum. ones are better for road racing vs drag or what not.

Whats the Ram p/n your looking at? I might be able to save you few bucks vs Jegs.

[25thZ28]

i've heard the same thing about the steel versus aluminium. the only real reason i picked an aluminium one was for the fact the friction surface is replaceable and i dont have to worry about hot-spots going too deep into the flywheel. glad to not hear any horror stories from either clutch on this site. i'll probably go with the ram because it is a tad cheaper, if i end up not liking it then it is deffinately the specII to try on second go around.


the P/N on the RAM clutch i was looking at is 798-98516, listed at 411.99, hopefully be ordering some of this stuff up next week sometime and get bad oscar in the Z.

i just searched that P/N, looks like LS series clutch, i need a pull style clutch for a LT1 setup.

[Darren]

I cant remember excatly the clutch I got, I will look when I get home. But I think it was a RAM Powergrip clutch...I will say I absolutley love it tho

The p/n come up as a LT1 Clutch set, but that price you listed must be old. I searched and summit has it at 469.95, jegs at 469.99 and LM performance at 549.95 OUCH!!
