Why King Bearings Stand Out
The MB5877SI010 set is designed for GM LS-Series and Vortec engines, offering a perfect balance of performance and reliability.

The 0.010" undersize accommodates machined crankshafts, making it a versatile choice for engine builders. King’s commitment to quality, backed by over six decades of expertise, ensures these bearings meet the demands of both street and track applications.
