Aero Engines Inc has identified that many Active Fuel Management lifter failures are not due to defective lifters, but rather issues with oil pressure or oil control within the AFM system.

The AFM system operates within a normal oil pressure range of 27 PSI to 66 PSI. Activation and deactivation of AFM lifters are controlled by the Valve Lifter Oil Manifold, also known as the VLOM.

In several warranty cases, AFM lifters have been found stuck in a compressed position. This is often caused by the VLOM commanding activation or deactivation at the wrong point in camshaft rotation, rather than a fault within the lifter itself.

A 6.2L DOD Delete Engine is a modified version of the original 6.2L GM engine where the Displacement on Demand system, also known as Active Fuel Management, has been removed. This improves long-term durability by eliminating the frequent cylinder activation and deactivation that can contribute to premature lifter, camshaft, and valvetrain wear.

• Improved Durability: Eliminates common DOD-related lifter and camshaft failures.
• Consistent Performance: All cylinders remain active for smoother full-time V8 power.
• OBDII Tuner Required: Add a compatible tuner to your OBDII port to complete DOD / AFM delete operation.
• Heavy-Duty Ready: Ideal for towing, hauling, high-mileage vehicles, and performance use.
