Product Description

STD

King "HP" bearings are a bi-metal aluminum silicon alloy featuring fine micro-bore finish. HP series are ideal for high-load, short-duration racing. Also for medium-load, long-duration racing such as circle track engines using nodular cast iron crankshafts. Wall thickness tolerances at an amazingly tight plus or minus .0001", 0.015" thick top layer for superior macro particle embed ability and conformability. Mains are 1/2" grooved for improved oiling to the rod journals.
