Due to the shortages I have decided to Sell Used AFM lifters. All lifters have been inspected for damage with basic inspection. I have pulled the lifter apart to inspect for damage to the locks for the AFM system. I have not disassembled the hydrolic portion. The lifter may (most Likely not though) have excesive oil leakage up pushrod. I have no way to inspect or test for that. I would personally have no issue installing these in my own vehicle if I was on a budget.
