COMP Cams 5560-16KIT Standard DOD Delete Lifter Kit for GM Gen IV 6.0L LS Engines

The COMP Cams 5560-16KIT Standard DOD Delete Kit is a complete 16-lifter replacement kit designed to permanently eliminate the Active Fuel Management (AFM) / Displacement on Demand (DOD) system on GM Gen IV 6.0L LS engines. This kit replaces all 16 cylinder deactivation lifters with standard solid-roller-style lifters, preventing the common AFM-related lifter failures that plague these engines and restoring full, reliable cylinder operation at all times.

GM's AFM/DOD system is a known weak point in Gen IV LS engines, frequently causing lifter collapse, oil consumption issues, and costly engine damage. By deleting the DOD system with this COMP Cams kit, enthusiasts and engine builders can eliminate this failure point entirely — ideal for performance builds, high-mileage rebuilds, or any engine where long-term reliability is the priority.

Key Features:

• Eliminates Active Fuel Management (AFM) / Displacement on Demand (DOD) cylinder deactivation system
• Designed specifically for GM Gen IV 6.0L LS engines
• Prevents common DOD lifter collapse and associated engine damage
• Compatible with DOD delete camshafts and standard LS camshaft upgrades
• Manufactured by COMP Cams to precise tolerances for proper fit and reliable operation
• Ideal for performance builds, daily drivers, and high-mileage engine rebuilds

Note: A DOD delete camshaft, valley cover delete plate, and an ECU tune are typically required to complete a full AFM/DOD delete. This kit addresses the lifter replacement portion of the conversion.
