About this part

Product Details

You get a full set of crankshaft main bearings in this kit, which means one box handles the whole bottom end rebuild. These ACL bearings are built to spec for your Hyundai G4KC (Theta) 2359cc engine. They are a .50mm undersize set, meaning they are designed to be used when the crankshaft journals have been machined down by 0.50mm to clean up wear or damage.

ACL has been making engine bearings for a long time, and they know what it takes to keep your engine running smoothly. These bearings are made with a strong overlay material that's designed to handle the pressures and heat inside your engine. When you're rebuilding an engine, getting the main bearings right is crucial for oil pressure and overall engine health. This set fits a range of Hyundai and Kia models from the early 2010s, including the Genesis Coupe, Sonata, Forte, Optima, and Sportage, all equipped with the G4KC (Theta) 2359cc engine.

Make sure to check your crankshaft journals for wear and have them machined to the correct size if needed before installing these bearings. Always follow the manufacturer's torque specifications and lubrication procedures during installation to ensure proper function and longevity.
