Reply To: Updated Lifters in the 5.3

This is not true unfortunately. The lifters are the exact same. There has been no change in either the lifter design for OEM builds or OE GM replacement parts. We have a service department full of 2021-2023 vehicles getting lifter jobs and cam jobs and engine replacements, lifters are the exact same. The problem has has never been the lifter, it is the restriction of oil going to them with AFM/DFM and the valve lifter oil manifold. No new lifters.
