Clevite P-Series Main Bearings

Clevite P-Series main bearings are the oldest members of the Clevite 77 bearing family and are intended for high-revving engines. To compensate for the high-load factors and distortion in these engines, these bearings have higher eccentricity and a high crush factor. P-Series bearings are constructed of tri-metal cast copper lead. They have a steel back for support, a cast copper lead lining to withstand the loads of engine operation, and an electroplated babbit overlay on the running surface to provide searing surface qualities. In addition, the oil grooves on most applications extend all the way around both halves for better oiling. Clevite P-Series main bearings are an ideal design, producing a degree of conformability, embedability, slipperiness, and fatigue resistance, not found in original equipment and competitive bimetal bearings.

Sealed Power CP-Series Rod Bearings

Federal Mogul CP-Series rod bearings 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. Order the set designed for use with your make/model and engine application.

Sealed Power Cam Bearings

Today's engines operate under very demanding conditions. Sealed Power has responded to this challenge with their babbit high performance cam bearings. They feature high embedability and conformability and a special "sacrificial" design that enables the bearing surface to deform under extreme loads, preventing any wear and damage to the camshaft.

Sealed Power A-Series Rod Bearings

Sealed Power A-Series rod bearings can actually polish the journals on your crankshaft. That's because there's 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. Order the replacement bearings designed for your vehicle make and engine application.

King SI-Series Rod Bearings

King SI-Series rod bearings are recommended for OE applications. They're designed for aftermarket gasoline or diesel engine rebuilding and performance engines with OE crankshafts. These direct replacements have an improved finish for reducing microscopic ferrite peaks on improperly ground or polished nodular cast iron crankshafts. King SI-Series rod bearings also feature improved oil clearance to reduce wear and increase engine life—which, in turn, lessens operating noise, vibration, and excess oil flow. Hundreds of sets are available; order the bearings recommended for your vehicle.

Speed-Pro Competition Series Main Bearings

If you're building a serious performance engine, then you'll want to consider Speed-Pro Competition Series main bearings. They were developed in NASCAR and Pro Stock competition, so you know they're tough. The bearings are built on premium 1020AK steel backings and overlaid with Speed-Pro's super-duty H-14 alloy. That layer is then 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. Speed-Pro's engineers have determined that such a layer can actually move around under high loads—sometimes with undesirable consequences. Depending on the application, these main bearings have oil grooves for enhanced lubrication, while maintaining a maximum bearing surface area. They also feature Speed-Pro's exclusive contoured-flange thrust bearing technology for higher thrust-loading capacity. Competition Series main bearings are available in nearly a hundred configurations for countless vehicle and engine applications.

Enginetech Rod Bearings

Enginetech rod bearings are made of high-quality alloys, based on the application requirement. They are made on state of the art equipment, ensuring consistent bearing thickness for proper oil clearances, and parting line chamfers are precisely controlled, ensuring they are cut at the correct angle to allow for the proper amount of oil bleed-through without reducing oil pressure. The materials are high strength (load capacity), but also have good anti-friction properties (wear resistance, anti-seizure, and embeddability). Enginetech rod bearings provide extra protection and better durability within your rebuild. Select the size needed.

Enginetech Main Bearings

Enginetech main bearings are made of high-quality alloys, based on the application requirement. Manufactured on state-of-the-art equipment, this ensures consistent bearing thickness for proper oil clearances, and parting line chamfers are precisely controlled, guaranteeing they are cut at the correct angle to allow for the proper amount of oil bleed-through without reducing oil pressure. Thrust washers are included, where appropriate, when they are not already molded into the main bearing. The materials are high strength (load capacity), but also have good anti-friction properties (wear resistance, anti-seizure, and embeddability). Enginetech main bearings provide extra protection and better durability within your rebuild. Select the size needed.
