H-Series Performance Features:

• Medium eccentricity level optimized for mid to high RPM operation
• Hardened steel backing for enhanced strength and fretting resistance

About H-Series Bearings: Originally developed for NASCAR competition, H-Series bearings are suitable for all types of performance and racing engines. The medium eccentricity provides ideal contact patterns covering approximately 2/3 to 3/4 of the bearing surface, making H-Series the recommended starting point for most high-performance applications. These bearings work exceptionally well with crankshafts featuring oversize fillets and engines operating in medium to high RPM ranges.

Important: This product is sold as a paired set (two bearing halves for one connecting rod). For a complete engine rebuild, order one set per cylinder—quantity of 6 for a 6-cylinder engine, quantity of 8 for an 8-cylinder engine, etc.
