If you're building a serious competition engine, then you'll definitely want to check out Sealed Power Competition series main bearings. They were developed in NASCAR and Pro Stock competition, so you know they're tough. They're built on premium 1020AK steel backings and overlaid with Sealed Power's super-duty H-14 alloy. That's covered with a nickel barrier, followed by a thin lead-tin-copper overplate. However, unlike other performance bearings, there is no flash tin layer on top of that. Sealed Power's engineers have determined that such a layer can actually move around under high loads--sometimes with undesirable consequences. These bearings have 3/4 oil grooves for enhanced lubrication, while maintaining a maximum bearing surface area. They also feature Sealed Power's exclusive contoured-flange thrust bearing technology for higher thrust-loading capacity.
