      Description

      Engine Valve Lifter Kit. The Active Fuel Management (AFM) Engine Valve Lifter and Guide Kit, set of 16, is designed to replace the original valve lifters and guides on compatible LS Engine V8 vehicles equipped with Active Fuel Management. This kit helps restore proper lifter operation, contributing to improved engine performance and efficiency by enabling cylinder deactivation and reactivation as needed.

      Construction and Appearance. The kit features hydraulic lifters made of durable steel, paired with plastic guides to ensure precise valve operation and reduce wear. The components are engineered to meet high aftermarket quality standards, ensuring reliable performance and longevity under typical operating conditions.

      Installation. Installation involves replacing the factory lifters and guides on the front sides of the engine. The process is straightforward for experienced technicians and does not require drilling, but proper attention to orientation and inspection of related components is recommended.

      Warranty. This product includes a 2-year warranty covering manufacturing defects and performance issues under normal use.

      Application. Specifically designed for 2007–2020 Yukon models equipped with LS V8 OHV engines featuring Active Fuel Management (AFM), excluding vehicles with newer Dynamic Fuel Management (DFM) systems.
