Q:What bearing is the better of the 2 a 8-2555A or 8-2555cp
A:Hi Shadetree, happy to help you! The Sealed Power Connecting Rod Bearing Set (Part No. 8-2555A) is Bi-metal aluminum alloy, A-Series set. These Sealed Power A-Series rod bearings can actually polish the journals on your crankshaft. That's because there is a small percentage of silicon mixed in with the aluminum and tin that make up the bearing-surface alloy. The silicon is there for wear resistance, but its toughness actually smoothes the journals of a crank with a surface that hasn't been optimized! This special surface alloy is laid over a high-strength 1010 steel backing and delivers improved seizure and corrosion resistance, as well as better wall variance control. It also helps to minimize debris embedding, which can score the crank's surface. The Sealed Power Connecting Rod Bearing Set (Part No. 8-2555CP) feature classic tri metal construction and are a good choice for either street or moderate competition use. They have rugged 1010 steel backings covered by Federal Mogul's H-24 copper-lead alloy. On top of this is a nickel barrier, followed by the tri metal lead-tin-copper overplate that gives these bearings their strength and fatigue resistance. The bearings are then entirely covered with a flash coating of tin.
Q:I ordered the connecting rod bearing set. I just want to ensure that it has all 16 bearings.
A:Yes, it is sold as a set of 8.
