These lifters will only work in 2007-2018 GM Engines with the AFM System. They will NOT fit the 2019+ with the DFM System.
Set of 8 US MFG AFM Lifters plus 8 Roller Lifters for 1999-2016 Chevy GM 5.3L 6.0L
Total of 16 lifters.
AFM Lifter failures in GM engines are the result of another problem in the engine. They are not the cause of the failure. That problem needs to be resolved as part of the repair or repeated lifter failures will occur. Please read the tech bulletin in images and watch the videos in the links below:
