This all-in-one top-end rebuild kit is designed to permanently disable the factory AFM/DOD cylinder deactivation system on GM Gen 5 5.3L V8 engines, eliminating common factory faults including lifter collapse, loud engine tick, rough idle, misfire and oil consumption issues. The Non-AFM camshaft with matched LS7 solid lifters delivers consistent full-cylinder operation for smoother power output and extended engine service life. MLS multi-layer steel head gaskets feature outstanding heat and pressure resistance to prevent coolant and oil leakage during rebuild. High-tensile strength head bolts provide stable clamping force for long-term reliable sealing. All internal valve train components adopt wear-resistant alloy materials with professional surface hardening treatment, perfectly meeting the full top-end overhaul demands for GM pickup trucks and full-size SUVs.

1-Year limited warranty against manufacturing defects. Our dedicated after-sales team provides comprehensive technical support for all buyers throughout product use and installation.
