King Engine Bearings
King has developed an extensive product offering that includes a wide range of engine bearings for automobiles, light-duty and heavy-duty trucks, marine, aviation, standby power, and many other types of internal combustion engines. When you need the best, you go to a specialist—and for the best bearings, you see King Engine Bearings. King focuses on one product—bearings—and nothing else. Their innovative, race-only Xtreme Performance tri-lecular main bearings are proven track-tough to handle the ground-shaking power of your race engine. King HP-Series main bearings are recommended for street and strip performance applications. They're designed for blown, turbocharged, NOS, and alcohol-fueled engines using aftermarket crankshafts. These main bearings have greater eccentricity for superior oiling at high rpm, and a chamfered surface for large radii crankshafts. HP-Series bearings also feature large, chamfered oil holes—and are available in 1/2 grooving for improved oiling to withstand high-rpm applications. Order the bearings designed for fitment with your specific engine.
