This plug kit is engineered to permanently disable the DOD/AFM cylinder-deactivation system on GM Gen V LT engines. By blocking the oil circuits that feed the DOD lifter solenoids, the engine operates continuously on all eight cylinders, improving valvetrain stability and eliminating a known failure point. The kit maintains stock oiling geometry and is suitable for performance upgrades or reliability-driven builds where full-time V8 operation is required.
