This plug kit is engineered to disable the DOD/AFM system on GM LT2 engines by blocking the factory oil-control passages used to activate cylinder deactivation. Once installed, the engine operates full-time on all eight cylinders, improving valvetrain stability and preventing lifter collapse associated with DOD/AFM operation. The plugs retain stock oiling geometry and are suitable for performance builds, camshaft upgrades, or applications requiring permanent removal of the DOD/AFM function.

Brian Tooley Racing LT2DODPLUGKIT Features:

• Fitment: GM LT2 engines as used in late-model Corvette applications
• Blocks oil passages for the factory cylinder-deactivation system
• Provides continuous eight-cylinder operation under all load conditions
• Direct-fit plug design requiring no machining or modifications
• Constructed from aluminum and hardened materials for long-term durability
• Suitable for camshaft or lifter upgrades that require permanent DOD/AFM removal

Brian Tooley Racing LT2DODPLUGKIT Includes:

• Oil passage block-off plugs
• Valley-cover plug as required
