Melling MDK400 Ls Afm Cylinder Deactivation Delete Kit

The Melling MDK400 LS AFM Cylinder Deactivation Delete Kit is a comprehensive solution for converting Active Fuel Management (AFM) engines to standard non-AFM operation. This complete conversion kit eliminates the complexity and common failure points associated with GM's cylinder deactivation system, providing improved reliability and consistent performance across all cylinders.

Complete Kit Includes:

• MDM delete camshaft designed for non-AFM operation
• 16 non-AFM hydraulic roller lifters for reliable valve operation
• 4 non-AFM lifter guides
• Camshaft thrust plate
• VVT (Variable Valve Timing) oil control valve

Key Benefits:

• Eliminates AFM lifter failure issues common in factory AFM engines
• Restores full 8-cylinder operation at all times
• Engineered, tested, and manufactured in the USA to Melling's exacting quality standards
• All components designed to work together as a complete system

Important Note: This kit requires reprogramming of the vehicle's Engine Control Module (ECM) or Powertrain Control Module (PCM) to disable AFM functionality. Vehicle will not be CARB compliant after ECM/PCM reprogramming. Professional installation and tuning recommended.
