Sealed Power 6-4020A.75MM Connecting Rod Bearing

General Motors Sealed Power Standard Premium A-Series Bi-Metal Aluminum Alloy Main Bearing Set 6-4020A75MM.Federal-Mogul's Sealed Power brand main bearings, available in half-groove, three-quarter-groove and full-groove designs, are manufactured using preferred OE technologies and cutting-edge materials that produce superior quality and durability.The companys patented Ramp and Flat Contoured Flange design, a significant improvement in engine-bearing technology, doubles thrust-load capability, reduces wear dramatically and improves lubricity between the flange face and the thrust surface.Lets Talk about the features and design character Sealed Power's Speed-Pro DUROSHIELD Competition Series Coated Bearings ~Crush Crush refers to the press fit that results from having a small section of the bearing extended above the housing bore when the bearing half is in set in place. Federal-Mogul's performance bearings have additional crush built into the design. This extra material helps to force the outside diameter of the beating against the rod or main bore when the assembly is torqued to specification. By increasing the surface contact between the bearing and it's bore, crush helps to compensate for bore distortion and aids in heat transfer. This is critical because the lubricating oil will break down and cause bearing failure if the area gets too hot.~Chamfer Performance engines often require added crankshaft strength, which mandates special bearings. Racing crankshafts employ a larger diameter fillet radius in the area where the rod journal meets the couterweight. This rounded inside corner increases crankshaft strength, but can interfere with the rod bearing. Many of their performance rod bearings feature a chamfer which provides the side clearance necessary for these cranks. The chamfer is only on the edge of the bearing that is alongside the crankshaft counterweight, thus maintaining as much bearing surface area as possible. Even when using our c
