YIDEZU Non AFM Camshaft Kit Fit For GM Chevrolet Gen V L83 2014-2021

Solve common Gen V engine AFM/DOD system failures permanently with this professional Non-AFM DOD delete rebuild kit. Factory active fuel management systems commonly cause lifter collapse, engine ticking, rough idle and long-term valve train wear. This comprehensive upgrade kit replaces stock vulnerable components with premium LS7-style lifters and non-DOD camshaft parts, fully disabling the problematic AFM/DOD function, restoring stable engine operation, eliminating abnormal noise and extending overall engine service life for GM Gen V platform vehicles.

Core Upgrade Advantages

• Permanent AFM/DOD Elimination: Completely removes factory Active Fuel Management and Displacement on Demand system defects, stopping recurring lifter failure, valve train tick and inconsistent engine operation caused by cylinder deactivation.

• LS7 Style High-Performance Lifters: Upgraded heavy-duty LS7 lifters feature enhanced structural strength and wear resistance compared with stock AFM lifters, delivering more durable valve train performance under daily driving and load conditions.

• Complete OEM-Grade Rebuild Set: Comes with all required gaskets, head bolts, lifter trays and sealing accessories for full top-end overhaul. No extra parts needed for one-stop professional repair and upgrade.

• Precision Gen V OEM Fitment: Custom engineered for GM Gen V LT-series engines with strict factory dimensional standards, ensuring perfect clearance, accurate valve timing and zero modification for direct installation.

• Improved Engine Reliability: Stabilizes oil pressure, reduces internal valve train friction, maintains consistent power output, and prevents progressive engine damage caused by failed AFM/DOD components.
