  • Enhanced tri-metal copper lead construction with nickel barrier and SecureBond adhesion 
  • Unique SecureBond adhesion process for superior stability between the top and intermediate layers
  • 15% - 30% greater load capacity than traditional bearings
  • Mains and rods are narrowed for large radius crankshafts
  • Greater rod bearing height improves bearing-to-bore contact/heat transfer and reduces spin potential at high RPM
  • 0.0005" metallurgically enhanced and hardened performance overlay withstands greater loads and better resists surface fatigue
  • Mains are 1/2 grooved for uncompromised lower shell load capacity
  • High-load, long-duration racing such as circle track, off-road, off-shore, and others that require steel crankshafts

    ACL tri-metal H-Series Duraglide main bearings for S/B Chevy 350 c.i. V-8.
    • Use H-series bearings with crankshafts that have oversize fillets and where engines run in the medium to high RPM range. 
    • H-Series bearings should be used if contact patterns obtained with P-series parts are too narrow. Contact pattern should ideally cover 2/3 to 3/4 of the bearing surface. 
    • If you aren't sure which type of performance bearing to start with,  the H-Series will be your best choice.

    Not to be confused with standard "passenger" car bearings, Clevite's P-Series is their oldest line of premium high performance bearings. These sets are specifically for 302-305-327-350 S/B Chevy "Large Journal" engines built from 1969-Up (with 2.100" rod journal). 
    • Use P-Series rod bearings where extremely high RPM’s cause severe rod bore close-in.
    • Use P-Series main bearings where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings. 
    Note: Will not work with 400 c.i. V-8.
