I have decided to sell new old stock AFM lifters I have had in a bin for a while. I'm selling them at what I believe I paid for them years ago. I Recommend full mechanical delete over oem AFM lifter replacement because it will fail again if at least not disabled. But if you are on a budget and just want to disable via someone like LT1swap.com, the lifter wouldn't release, and just replace a lifter this is for you.
