King Engine Bearings Silicon Alecular Bearings - Rod & Main Bearing Kits
Save money by buying your rod and main bearings at one time. You can choose any combination of undersizes for your application (example: rods .010" and mains .020"). Great bearings at even a better price.
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 the engine rather than scoring the crankshaft and causing long term damage.
