Overview

The Summit Racing™ Active Fuel Management Delete Combo is a kit designed to eliminate cylinder deactivation in GM Generation IV LS V8 engines. This combo includes hydraulic roller lifters, head gaskets, water pump gaskets, a valve lifter guide set, new head bolts, and an engine valley cover.
Show original supplier description
The Summit Racing Active Fuel Management (AFM) delete combo provides a comprehensive solution for removing the factory cylinder deactivation system, commonly referred to as Displacement on Demand (DOD), in GM Generation IV LS V8 engines. By replacing the AFM-specific components with standard non-AFM hardware, this kit helps improve reliability and engine performance in vehicles originally equipped with the deactivation technology. This kit is specifically intended for applications without a Positive Crankcase Ventilation (PCV) valve in the valley cover; for engines requiring PCV integration, an alternative kit configuration is required. Please note that a custom ECU tune is typically necessary after completing this conversion to ensure proper engine management and to disable the factory AFM system settings in the vehicle's computer.
