Clevite MS2321H High-Performance Tri-Metal Main Bearing Set

The Clevite MS2321H is a high-performance tri-metal main bearing set designed for the Dart LS Next engine platform. This bearing features Clevite's proven 77 Series construction, combining a copper-lead alloy layer with steel backing and an electroplated babbitt metal overlay. The steel backing delivers exceptional strength and durability, while the babbitt overlay provides critical surface characteristics including low friction and superior conformability—qualities that often exceed original equipment specifications.

H-Series Design Features:

• Medium eccentricity level with high crush for maximum bearing retention
• Enlarged chamfers provide greater crankshaft fillet clearance
• Manufactured without flash plating for improved seating and contact
• Optimized for engines operating in the mid-to-high RPM range
• Ideal contact patterns covering 2/3 to 3/4 of the bearing surface
• Recommended for crankshafts with oversized fillets
• Excellent starting point when bearing selection is uncertain

Construction Benefits:

• Tri-metal design combines strength, durability, and conformability
• Copper-lead intermediate layer provides load-carrying capacity
• Babbitt overlay ensures proper lubrication and embeddability
• Steel backing maintains dimensional stability under high loads

This main bearing set includes all bearings required for a complete installation. Clevite main bearing sets feature single-piece thrust bearings and are designed to meet the demands of high-performance and racing applications where reliability and precision are critical.
