Perfect Circle CB663P8 P-Series Connecting Rod Bearing Set Standard Size Small Block Chevy LS

The Perfect Circle CB663P8 is a complete 8-piece connecting rod bearing set engineered for Chevrolet small block and LS engines. This standard size P-Series bearing set features advanced TriMetal construction with a hardened steel backing, an intermediate copper-lead alloy layer, and an electroplated lead-tin-copper overlay for superior durability and load capacity.

Key Features:

• TriMetal construction with hardened steel backing and extra-thin overlays for enhanced strength
• Higher eccentricity and high crush factor design compensates for rod bore distortion in high-RPM applications
• Oil grooves extend around both halves for improved lubrication throughout the bearing surface
• Dowel holes in lower sections accommodate aluminum connecting rods
• Standard size rod journal: 2.099-2.100 inches, housing bore: 2.2247-2.2252 inches
• Maximum length: 0.842 inches, maximum wall thickness: 0.0620 inches
• Complete 8-piece set provides bearings for all cylinders in V8 engines

P-Series bearings are ideal for engine rebuilds where more demanding use is anticipated, including heavy-duty applications, motorsports, and street performance builds. The increased load capacity of the TriMetal design makes this an excellent upgrade from standard BiMetal bearings. Suitable as a direct replacement for OE bearings in most applications.
