16 GENUINE GM ACDELCO 12645725 AFM DFM LIFTERS – MADE IN USA – A full set of 16 Genuine GM ACDelco 12645725 hydraulic roller lifters — the factory original lifters specifically designed and validated for the Gen V DFM system and engineered to handle the complex oil pressure cycling required for 2019+ cylinder deactivation patterns. The L84 DFM system uses 16 AFM style lifters instead of the 8 used in earlier Gen III and Gen IV engines — every single lifter in this engine is an active fuel management style lifter and every single one needs to be replaced correctly for a proper long lasting repair. Genuine GM ACDelco — not aftermarket not imitation — made in the USA.
