2019+ Gen V LT L84 5.3L PowerHouse DOD/AFM/DFM Delete Kit (LTDFMD53)

Beginning in 2019, GM offered a new version of the AFM system, it is called DFM which stands for Dynamic Fuel Management. This variation requires a few different parts that the previous version when you need to repair or delete the system.

The DFM system in LS engines aims to improve fuel efficiency by deactivating half of the engine’s cylinders during light load conditions. However, it introduces complexity and potential reliability issues, such as increased oil consumption, uneven engine wear, and higher maintenance costs. The system can also negatively impact performance, particularly in high-performance applications, and limits the types of modifications that can be made. The PowerHouse DFM delete kit enhances your engines reliability, performance, and longevity.
