Product Advantages
This complete upper-engine rebuild kit is purpose-built to permanently eliminate the factory AFM cylinder deactivation system on L86 6.2 EcoTec3 engines.
- Non-AFM camshaft paired with solid lifters resolves classic AFM failures: collapsed lifters, persistent engine tick noise, rough idle, misfire codes, and excessive oil consumption; delivers consistent full-cylinder power without fuel-saving deactivation.
- MLS reinforced steel head gaskets withstand high turbo/NA combustion heat and pressure to stop coolant, oil and vacuum cross-leaks.
- Torque-spec high-strength head bolts maintain uniform clamping load to prevent head warping and gasket blowout.
- Full set of manifold, valve cover, stem and auxiliary seals covers all upper engine sealing needs in one kit, no separate gasket purchases required.
- All valvetrain and sealing components use OEM-grade wear-resistant alloy and heat-resistant composite materials, ideal for heavy-duty full-size trucks and luxury SUV full top-end overhaul.
Critical Installation & Purchase Notice
- Confirm your vehicle has L86 6.2L EcoTec3 engine, VIN 8th digit J before ordering.
- Cross-check all OEM part numbers and Non-AFM lifter configuration against your original parts prior to disassembly and installation.
- Professional engine repair shop installation is strongly recommended for accurate timing and torque procedure compliance.
