    • 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
