COMP Cams 5552-KIT Premium DOD Delete Kit for GM Gen IV LS Engines - 5.3L

The COMP Cams 5552-KIT Premium DOD Delete Kit is a comprehensive solution for permanently disabling the Active Fuel Management (AFM) system, also known as Displacement on Demand (DOD), on GM Gen IV 5.3L LS engines. This system eliminates the problematic lifter and valve train components that are prone to failure in AFM-equipped engines, replacing them with reliable conventional components for improved durability and performance.

Key Features:

• Complete kit includes DOD delete lifters, guide trays, installation hardware, and assembly lubricant
• Premium lifters engineered specifically for Gen IV LS applications with proper bore diameter and oil metering
• Eliminates common AFM lifter failures that cause engine noise, misfires, and catastrophic damage
• Hardened pushrod seats and precision-ground bodies for extended service life
• Includes all necessary components for a complete valve train conversion
• Compatible with stock or aftermarket camshafts without DOD lobes
• Professional-grade assembly lube ensures proper break-in protection

This kit is ideal for engine rebuilds, performance upgrades, or preventative maintenance on AFM-equipped vehicles. A custom ECM tune is required to disable the AFM system software after installation. Designed for GM Gen IV Small Block engines including 5.3L applications found in trucks, SUVs, and performance vehicles.
