King CR 811SI 010 CR Series Rod Bearings, Buick, Pontiac, .010 Fits select: 1968-1972 BUICK SKYLARK, 1979-1981 PONTIAC FIREBIRD

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. These bearings are available in the traditional Std, .010, .020, .030 and .040 specs.
