Restore V6 Power: Ultimate Gen V 4.3L LV3 EcoTec3 AFM Camshaft, Lifter & Timing Master Rebuild Kit
Are you dealing with the dreaded "lifter tick," severe engine misfires, or a sudden loss of power and rough idling on your 2014-2020 GM 4.3L EcoTec3 V6? These are classic, widespread symptoms of a collapsed Active Fuel Management (AFM) lifter—a notorious issue that quickly scores and destroys the camshaft on Gen V LV3 direct-injected engines. When a lifter fails on these hard-working trucks, a complete top-end teardown is mandatory. Restore factory-fresh pulling power, quiet your valvetrain, and get your work truck back on the road with this Ultimate AFM Camshaft, Lifter & Timing Master Overhaul Kit. Engineered specifically for the Gen V 4.3L V6 platform, this kit provides everything you need to properly replace your damaged camshaft and failed lifters while reliably retaining the factory AFM system.
Tearing down a Gen V engine requires replacing multiple single-use components and high-wear items. Instead of hunting down individual gaskets and specialized fasteners, this premium master overhaul package maximizes your engine teardown value by providing a complete, all-in-one solution. It features an OEM-spec 4.3L AFM camshaft, a full set of 12 hydraulic roller lifters (perfectly configured for the V6 engine), and premium Multi-Layer Steel (MLS) head gaskets. Crucially, this kit goes a step further by including a complete front-end timing chain and tensioner overhaul set, alongside mandatory Torque-to-Yield (TTY) cylinder head and cam phaser bolts, ensuring a safe, permanent, and professional rebuild.
(⚠️ CRITICAL FITMENT & INSTALLATION NOTE: This master overhaul kit is engineered STRICTLY for 2014-2020 GM 4.3L Gen V EcoTec3 V6 engines (LV3 code) equipped with Active Fuel Management (AFM). It flawlessly fits the Chevrolet Silverado 1500 and GMC Sierra 1500 (4.3L V6). This kit RETAINS the AFM system and is NOT a delete kit. Please carefully verify your exact year, model, and engine displacement before purchasing.)
Engineered to meet or exceed strict OEM specifications for long-lasting, leak-free, and whisper-quiet valvetrain performance under heavy workloads. Rebuild your EcoTec3 V6 engine the right way with BTSCAR's premium master components and drive with absolute confidence.
