Valve Springs

[RadRacer]

Anyone know the ID, OD, spring height, etc of our springs and/or LS6 springs? I'm looking around locally for a set of valve springs, and asking for LS6 springs isn't exactly cutting it :P. So, anyone know the dimensions?

I don't think it lists the free length, but for stock springs 1999 and earlier is 1.981 inches and for 2000 and later it's 1.960

That's what I was looking at before, but I wasn't sure if they were the same as the LS6's. I've got the retainers, just need a set of springs now, and, like I said, everyone's asking for spring specs, not what they came from.

Are those stock LS6 Springs? I didn't think they were double springs; the ad says they are, even lists ID for both springs, but the picture only shows a single spring.

Re: Valve Springs

yeah, weird. the pictures i've seen were not double either. i think summit might have messed up.

i understand why after some research. GM part number in '03 was 12565117, in '04 was 12565313. Now is 12586484 and for a package of 16 is 12499224.

EDIT:
Also found this. Looks like there are multiple LS6 springs.

"2001 LS6 springs had a blue stripe for .525" lift superseeded by Yellow stripe on the 2002 springs and puke green color stripe on the 2003 LS6 valve springs rated for .550" lift"

Re: Valve Springs

o well, guess I'll just stick with an online order. How hard is it to install valve springs with the motor in the car?

Re: Valve Springs

I like the air fitting for the spark plug hole, I wish I had that when Meatyshells and I did my springs. On one or 2 of the plug holes it was difficult, we finally ended up buying a 90degree adapter from ACE just to get to them I had only the straight air fitting for the spark plug holes. Good info.

Re: Valve Springs

You should get some rockers while you're at it! If you don't already have some..

Re: Valve Springs

Stockers are fine. I was debating going with some 1.7's, but the price vs gain isn't worth it.

Re: Valve Springs

Yes it is! Btw, why are you putting in stronger springs?

Re: Valve Springs

105# is what ZZP recommends in their description of the GT2 cam.

Re: Valve Springs

lmao 1.9 with a gt2 cam, bye bye valve covers?

Re: Valve Springs

Meaty, don't quite think they'll work :P. 1.8's is the highest I can run, and that's with modded retainers, and locks from ZZP, and it's still slightly above their recommended limit.
