King SI-Series Rod Bearing Set
Designed for aftermarket engine rebuilding and performance engines with factory crankshafts. The bearings have an improved surface finish for reducing microscopic peaks on improperly ground or polished nodular cast iron crankshafts. King SI-Series main bearings feature improved oil clearance to reduce wear and increase engine life, which in turn reduces operating noise, vibration, and excess oil flow. Because the bearings are unplated, wall variances are reduced by as much as 40% less than tri-metal (over-plated copper lead) bearings. KING's SI bearings easily exceed maximum peak load capacity for car and light duty applications. Minimized debris embedment.
