Description
Has the Displacement on Demand (DOD) or Active Fuel Management (AFM) system started ticking, sticking, or outright failed on your 2014+ GM 4.3L LV3 truck? Top-end valvetrain ticking, misfires, or collapsed lifters are common failure points on high-mileage Gen V engines. This SDPC direct-replacement repair kit equips you with all the genuine GM factory components required to restore valvetrain geometry and repair AFM lifter failures properly without requiring aftermarket ECM recalibration or custom tuning. Engineered specifically for the Gen V EcoTec3 4.3L V6 (LV3) platform, this kit restores original engine reliability and factory cylinder deactivation operation.
Tech Tip: We strongly recommend replacing the Valve Lifter Oil Manifold (VLOM) valley cover during this repair. The internal solenoids and fine mesh screen inside the original VLOM are frequent failure points that starve lifters of necessary operating oil pressure, leading directly to collapsed lifters and damaged camshaft lobes. You can add a brand-new updated GM VLOM assembly directly via the dropdown menu.
