King Engine Bearings Hyundai G4KF Crankshaft (Size 0.25 Oversized) Main Bearing Set

King Engine Bearings is well-known for making solid engine bearings that hold up to tough conditions. This main bearing set is made for Hyundai G4KF engines and is 0.25mm oversized, which is important if you're rebuilding or repairing your crankshaft. Using the correct size bearings is key to ensuring proper oil clearance and reducing friction, which helps your engine run smoothly and last longer.

This set uses King's XP material, which is a high-performance overlay that offers improved durability and wear resistance compared to standard bearings. The 0.25mm oversize means these bearings are designed to be used with a crankshaft that has been machined down by 0.25mm. This is a common practice during engine rebuilds to achieve the correct bearing-to-crankshaft clearance when the original journal surfaces have wear or damage. Proper installation, including ensuring the crankshaft journals are clean and within the specified tolerance, is crucial for the longevity of these bearings.
