MICHIGAN 77 MS2294H H-Series Main Bearing Set GM LS 6.2L 7.0L

The MICHIGAN 77 MS2294H H-Series Main Bearing Set is a high-performance engine bearing kit designed for GM/Chevrolet LS V8 engines, specifically the 6.2L supercharged and 7.0L applications including LSA, LS7, and LS9 engines. This professional-grade bearing set delivers race-proven durability originally developed for NASCAR competition.

Key Features:

• Tri-metal TM-77 bearing material with hardened steel backing and thin overlay for superior strength
• Medium level of eccentricity with high crush factor for optimal crankshaft support
• 1/2 groove upper bearing design for effective oil distribution
• Enlarged chamfers for greater crankshaft fillet clearance
• Made without flash plating for better bearing seat contact
• Standard size bearings for stock crankshaft dimensions

H-Series bearings are engineered for engines running at medium-to-high RPM ranges and work with crankshafts that have oversize fillets. The cast copper-lead construction provides approximately 20% greater fatigue strength compared to sintered powdered metal alternatives. Ideal for performance builds, racing applications, and high-output street engines that demand maximum reliability under extreme operating conditions.
