Review KING ENGINE BEARINGS Mb 517si Crankshaft Main Bearing Set

Introducing the MB-517SI crankshaft bearing set from KING Engine Bearings, an essential upgrade for high-performance applications. This set includes four fully-machined, oversized crankshaft bearings designed to deliver superior strength, durability, and reliability compared to OEM bearings.

The MB-517SI bearings are manufactured using KING's proprietary Micro-Alloy Steel, which boasts an ultimate tensile strength of over 150,000 psi. This high-strength material ensures that the bearings can handle the increased stresses and loads common in high-performance engines.

Each bearing features KING's patented Flange-Relief Design, which provides enhanced clearance between the bearing flange and piston crown. This design allows for more piston-to-wall clearance, reducing the risk of piston-to-bore contact and resulting in increased engine life and improved performance.

The MB-517SI bearing set is also compatible with MB-style connecting rods, making it an excellent choice for engines using this rod design. The bearings are precision-machined to ensure perfect fitment and are supplied with a light machinery finish to provide an optimal surface for the piston rings.

In addition to their unmatched strength and durability, the MB-517SI crankshaft bearings offer superior oil retention. The bearings' increased width and proprietary oil grooves ensure that they retain an ample supply of oil, minimizing friction and reducing the risk of bearing failure.

Furthermore, the MB-517SI bearing set is suitable for various engine applications and can be used in both naturally aspirated and forced-induction engines. KING's dedication to creating high-quality, performance-focused components ensures that these bearings will provide exceptional performance and reliability, making them an excellent investment for any engine builder or enthusiast.

In summary, the MB-517SI crankshaft bearing set from KING Engine Bearings is a must-have for high-performance engine applications. These oversized, high-strength bearings offer superior durability, increased piston-to-wall clearance, and enhanced oil retention, leading to improved engine performance and reliability.
