King, Silicon Alecular Main Bearing Set, Chev SB SJ, .010"

King Silicon Alecular Bearings
The silicon particles help round off high spots on the crank surface during engine operation, which reduces friction & related wear. 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, SI bearings are unplated and bored, hard-particle debris is instantly flushed through the bearing and filtered out of engine rather than scoring the crankshaft and causing long term damage.
