Product Advantages

1. One-stop complete top & bottom end overhaul solution for G4KJ direct injection engines, covers crank, connecting rods, pistons, bearings, valves, timing VVT system and all sealing gaskets, no separate component procurement required for full engine rebuild.
2. High-strength forged crankshaft and reinforced connecting rods adopt precision quenching heat treatment, effectively solve common G4KJ failures: abnormal engine knocking, rod journal wear and crank deformation under heavy load towing conditions.
3. Optimized pistons and low-tension piston rings improve cylinder sealing, greatly reduce excessive oil consumption, blue exhaust smoke and compression loss typical on high-mileage GDI engines.
4. Complete E-CVVT timing chain kit with brand-new VVT phasers eliminates cold start rattling, timing stretch and P0010/P0011 VVT fault codes, restores stable power output and fuel economy.
5. Hardened intake/exhaust valves enhance combustion sealing, avoid power drop and rough idle caused by valve recession; MLS multi-layer steel head gasket resists high direct injection heat to block coolant and oil cross-leaks.
6. Low-friction bimetallic main/rod bearings with matched thrust washers stabilize crankshaft oil film, reduce vibration and extend engine service life. All parts strictly follow OEM dimensional standards for direct bolt-on installation without modification.

Purchase & Installation Notice
