Any one use the ls6 valve spring. till what lift are they good. They are pretty cheap on gm parts direct. i need to keep cost down....only 16.

 

ls6 springs are good till 550 I believe

 

there are 2 LS6 springs early blue stripe and late yellow,from what I have read blue will handle .530 and yellow .560,there must be guys here that know for absolute

 

gotta a set of 915 comps for sale, $100.
got 500 miles on them..
good up to .600 lift

 

thats a good deal.

 

I got my ls6 springs from gmpartsdirect.com to use in my truck. Went with Comp Cam that I got from a local shop, and Chromoly push rods from Summit Racing. So far I have been happy with my choice. Order the springs from mentioned site, it will save you money.

 

Are the LS6 springs any quieter than the Comps? Just wondering if I would lose some of my false KR by switching out my 915's for them.

 

01 thunder, why u selling them?......yea i'm intrested.

 

went to the 916 spring.
it was what was recommended by Thunder Racing for the cam I have.
Nothing wrong with them at all.
they where brand new
