Before I get flamed, I've searched. I know the yellow ls6 springs are supposed to be good for almost .580 and have around 294# seat pressure. That said, would they be a good spring for 220/224 .575" lift on 112 LSA? That lift is cutting it close. Thanks.

 

Personally, I would upgrade to a higher rated spring. .005" is not enough comfort room for me.

 

Yea, that's cutting it close, not to mention the ramp rates of the lobes make a difference also. If the lobes are very aggressive, you're going to want more seat pressure. The LS6 springs have 90# of closed seat pressure as opposed to 130# of the popular PAC springs (can't remember the part number off the top of my head right now...)

 

I run them on the boosted truck with teh ls6 cam? no problems thus far.

 

LS6 cam = LS6 springs, makes perfect sense, even boosted . I'm running LS6 springs with my current baby cam, and I will be using them in my LQ9 also, which I have a Vinci Trucker cam for (216/224 .551/.551 115).

 

I'm running Yellow LS6 Springs on a 216/218 .563/.563 114lsa and the truck has 8lb of boost.

 

thanks, guys! so it sounds like i need to go ahead and get some comp 918 springs.

 

go with pac 1218

 

I would not waste my money on comp springs. Spend the extra 50 or so bucks and get some patriot duals. Then If you ever go to a bigger cam you have springs good to .650 lift. Here are my comp springs. This Is why I will never put another comp product in my truck. Oh and the lift of the cam was only .574 int and .572 ext.

 

Nooooo! Look at the pics above, that is the new, updated "silver" Comp 918's in that pic. PAC's FTW!
