These are for a stock replacement for a 5.3 LS4. Bosch Part Number 0280158077, GM Part Number 12580579.

Also new GM part number is 89017704

And Ac-delco part number 217-2255

I like you could not find what lb they are maybe you can try a stealership using the GM part number.

Thanks for the #'s. They're the stock injectors on my SS, just trying to figure out how much bigger 28# would be. I'll try a parts dept tomorrow if no one on here can find it...I just hate dealing with them.

I want to say the factory injectors on the LS4's are 22lb ,but I cannot find any proof of this.

If you already have your tuner picked out you can have him hook up to your computer and he can look at the factory injector data and be able to tell you what lb they are.

It was more curiosity than anything. I've already upgraded to 28# to fit the new fuel rail, I was just wondering exactly how big of a bump that was.
