Clevite CB663FND10 F-Series LS Rod Bearing Undersize - 010

The Clevite CB663FND10 is an F-Series TriMetal connecting rod bearing featuring a lead-tin-indium-alumina electroplated overlay applied over a cast bronze lead substrate for maximum performance and reliability. This bearing is designed for Chevrolet V8 engines including LS and small block applications, and is manufactured with .010" undersize dimensions for use with reground crankshafts.

Advanced F-Series Technology:

• 126% increase in load carrying capacity before seizure versus conventional copper, tin, or lead overlay bearings
• Capable of carrying maximum loads of up to 12,000 psi
• Higher seizure resistance with no additional thickness compared to traditional bearing designs
• Increased fatigue strength and wear resistance overlay

Performance Features:

• Hardened steel back construction with three-layer TriMetal design
• Ramp and pad thrust face creates increased oil pressure to the thrust wear surface, increasing lubrication and bearing cooling
• Medium eccentricity and high crush factor for optimal contact patterns
• Enlarged chamfers for greater crankshaft fillet clearance

The CB663FND10 represents the latest advancement in high-performance bearing technology, ideal for competition engines, performance builds, and NASCAR-type racing applications where maximum durability and seizure resistance are critical.
