Clevite Engine Crankshaft Main Bearing Sets

Clevite Engine Crankshaft Main Bearing Sets carry on a legacy that began in 1929 with the development of the first precision insert-type bearing — a heritage that has made Clevite the benchmark for engine bearing quality across stock rebuilds, street performance, and professional motorsports. Trusted by engine builders, machine shops, and racing teams worldwide, these main bearing sets are engineered to deliver the crankshaft stability, wear resistance, and precision fit your engine demands.

Key Features:

• Bi-Metal Aluminum Silicon Construction: 100% lead-free aluminum silicon bi-metal design delivers environmental compliance alongside superior performance, with higher silicon content than comparable competitive bearings for enhanced journal surface conditioning
• Superior Strength and Conformability: Harder aluminum alloy interacts closely with journal surfaces for improved strength, conformability, seizure resistance, and outstanding wear life
• TriMetal™ Performance Series: Features a hardened steel back, copper-lead alloy substrate, and electroplated white metal overlay — delivering an ideal balance of conformability, embedability, slipperiness, and fatigue resistance for high-demand applications
• Multiple Series Available: A range of series options — including H, HC, F, P, and V — are available to match specific application requirements, from street rebuilds to full competition engines
• Precision-Bored Inside Diameters: 100% bored IDs ensure optimum surface characteristics and consistent dimensional precision across every bearing set
• Strict Dimensional Tolerances: Engineered to maintain proper oil clearance and optimal oil film thickness, meeting or exceeding OEM standards for strength and durability
• High-Performance Crankshaft Compatibility: Enlarged chamfers on select series provide greater crankshaft fillet clearance for performance and racing crankshaft applications
• Standard and Undersize Variants: Available across an extensive range of applications in standard and undersize configurations to suit both fresh builds and worn journal repairs

From daily driver rebuilds to NASCAR-level competition engines, Clevite Crankshaft Main Bearing Sets provide the foundation of crankshaft stability your engine requires. With nearly a century of precision bearing innovation behind every set, Clevite remains the engine bearing of choice for professionals and enthusiasts who demand nothing less than the best.
