Complete 2.0L G4NC Master Engine Rebuild Kit for Hyundai & Kia: Restore Factory Power & Reliability
Experiencing catastrophic engine failure, severe rod knock, or a massive loss of compression in your 2.0L GDI engine? A worn-out rotating assembly or blown head gasket doesn't have to mean the end of your vehicle's lifespan. Instead of risking your money on a high-mileage junkyard motor, our Master Rebuild Overhaul Kit provides the exact internal components needed to fully rebuild your engine from the ground up, restoring factory performance and saving you thousands in long-term repair costs.

This kit provides a comprehensive, professional-grade mechanical rebuild solution designed to address both bottom-end and top-end failures. At the core of the package is a precision-machined 2.0L G4NC crankshaft paired with heavy-duty connecting rods, complete piston assemblies, and a premium bearing set (featuring thrust washers) to ensure a smooth, durable rotating assembly. For the top end, the kit supplies 16 brand-new intake and exhaust valves alongside a complete set of 10 cylinder head bolts. To guarantee a perfect, leak-free seal, we include a complete engine overhaul gasket set featuring a highly durable Multi-Layer Steel (MLS) head gasket. As an added bonus for mechanics and DIY rebuilders, essential piston ring installation tools (compressor and pliers) are included right in the box.

IMPORTANT INSTALLATION NOTES:

Engine Code Verification is STRICTLY REQUIRED: This kit is exclusively designed for the 2.0L G4NC Gasoline Direct Injection (GDI) engine. It will NOT fit MPI engines or other 2.0L variants. You must verify your specific engine code and the OE part number (23110-2E501) via your VIN before purchasing.

Professional Installation Recommended: Engine rebuilding requires precision measurement and assembly. While ring installation tools are provided, proper clearances must be checked by a qualified automotive technician to prevent premature engine failure.

Engineered as a premium direct-fit replacement, this master kit is fully compatible with popular 2012-2021 models including the Hyundai Elantra, Tucson, Sonata Hybrid, and Kia Forte, Optima Hybrid, and Soul equipped with the 2.0L G4NC GDI engine. Invest in the longevity of your vehicle today with complete confidence. Should you have any fitment concerns prior to checkout, our dedicated support team is available to assist you. We proudly offer a hassle-free return policy for all uninstalled items kept in their original packaging.
