Clevite MS2411H H-Series Main Bearing Set for GM LS-Series Engines

The Clevite MS2411H is a high-performance H-Series main bearing set engineered specifically for GM LS-series engines with aftermarket crankshafts. Originally developed for NASCAR racing applications, these bearings deliver professional-grade performance and reliability for competition engines, high-performance street builds, and racing applications.

Advanced H-Series Construction:

• TriMetal construction featuring hardened steel back with cast bronze substrate and copper/tin/lead overlay
• Factory-applied design without flash tin plating for superior bearing seating and heat transfer
• Medium level of eccentricity to minimize rod housing bore deflection and deformation
• High crush design ensures optimal heat transfer and resistance to rotation under minimal oil film conditions
• Enlarged chamfers provide greater crankshaft fillet clearance for aftermarket cranks with larger journal radius
• Ramp and pad designed thrust face for enhanced thrust load capacity

Performance Benefits:

The MS2411H features larger chamfers than the MS2199 series, making it the premium choice for aftermarket crankshafts with oversized fillets. These bearings excel in medium to high RPM applications and are ideal for engines running with performance crankshafts. The absence of flash plating provides better initial seating characteristics critical for race engine durability.

Application:

Designed for use with standard-sized aftermarket crankshafts in GM LS-series engines. Not recommended for stock OEM crankshafts. Sold as a complete main bearing set. If you're uncertain which performance bearing series to choose, the H-Series is the recommended starting point for most high-performance applications.
