Melling MDK400-HPT AFM Delete Kit with Tuner, Camshaft and Lifters

The Melling MDK400-HPT is an all-in-one Active Fuel Management (AFM) / Displacement on Demand (DOD) delete kit, also called a cylinder deactivation delete kit. It bundles the mechanical parts for the conversion with a tuner, so you don't have to source the pieces separately.

Kit Includes:

• Billet steel AFM/DOD delete camshaft with a stock-replacement grind
• 4 non-AFM lifter guide plates (lifter trays)
• Camshaft front thrust plate
• VVT (variable valve timing) oil control valve / solenoid bolt
• HP Tuners RTD flash tool, preloaded with a Melling AFM/DOD/DFM delete tune

Key Features:

• Designed to remove the AFM system and the lifter failures associated with it
• Smartphone-based programming through the included flash tool, with no separate tuning device needed
• The programming interface also works as a scan tool. It can monitor live data and read and clear diagnostic trouble codes.
• SEMA Emissions Certified for 2026

A complete kit like this helps with AFM conversions because the camshaft, lifters, guides and tune come together in one package.
