King XP-Series rod bearings feature advanced metallurgical and geometric technologies that meet extreme performance loads. They were developed for all performance applications that use forged steel aftermarket crankshafts and produce high loads for extended periods. King focuses on one product—bearings—and nothing else. Their innovative race-only Xtreme Performance Max Black Tri-Metal rod bearings have a 24 percent stronger overlay and 17 percent more fatigue strength by using a micro process called SecureBond. Built with enhanced tri-metal, King XP-Series rod bearings layer copper-lead construction with a nickel plate barrier and a lead/tin/copper Babbitt overlay over a steel backing in an adhesion process that provides superior stability and durability. King's advanced control measures hit a bull's-eye, maintaining wall thickness tolerances far tighter than their competitors—at an amazing +/- .0001 in.! XP-Series rod bearings are narrowed on the crank cheek side with increased crush height for improved bearing-to-bore contact, heat transfer, and reduced spin potential in high-rpm applications.

King HP-Series cam bearings are precision-machined to tight tolerances to control installed oil clearances, reducing operating bearing pressure. These cam bearings are constructed from seamless steel tubing with a thin layer of lead based babbit material to reduce microscopic deflections. The babbit is quickly cooled in the casting process to achieve a very fine grain structure, doubling tensile strength, therefore, the HP-Series offers much more fatigue strength than conventional bearings, and can withstand racing spring loads, while maintaining the excellent surface characteristics of babbit. King also offers HP-Series bearings with a fluoropolymer coating. Bearings with this coating retain engine oil on the surface, even under extreme heat and pressure—a great advantage! Plus, being a lubricant, it provides backup during start-up and in the event of momentary oil starvation. Use track-tough King HP-Series cam bearings in your engine—and experience the difference.

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.

Sierra Marine offers a wide selection of parts, including thrust bearings to maintain, tuneup, or overhaul your boat. Thrust bearings support the axial thrust of both horizontal and vertical shafts. The functions are to prevent the shaft from drifting in the axial direction and to transfer thrust loads applied on the shaft. A boat's thrust bearings transfer the propeller's thrust from the shafting to the hull structure, which allows the propeller to be partially decoupled from the engine, while still allowing the engine to drive the propeller. Select the bearings in the best application option for your needs.

King TFC-Series engine main bearings feature a special factory applied nano-composite polymer coating—with no added thickness! The Top Fuel Line represents the culmination of the innovative and goal oriented research and production from King Engine bearings House. These bearings are available for a wide range of vehicles, especially year/make and engine applications from the 1960s and '70s. Additional details: TOP FUEL BEARINGS with K-40 POLYMER COATING: This coating composition was specially designed for engines experiencing continuous metal-to-metal contact, which is characteristic of the extreme loading and conditions found in various categories of drag racing. K-40 is used for Top Fuel, Funny Car, Pro Mod and similar applications—where bearings are required to resist metal-to-metal contact and deformation. Extreme loads cause the oil film to break down, allowing contact between the bearing and crankshaft surfaces. Maintaining low friction, even during the conditions of metal-to-metal contact, is crucial to the life of any engine bearing. King TFC bearings are designed to withstand the loading generated from 10,000 hp Top Fuel engines. TFC winning attributes: * HIGH STREGTH STEEL: able to withstand extreme loads * SPECIAL DUCTILE BRONZE LINING: will not crack under significant plastic deformation caused by high power engine (10,000 hp) * EXTRA THICK BABBIT LINING: strengthened by copper, excellent conformability * K-40 POLYMER LAYER: provides excellent anti-friction and anti-seizure properties during metal-to-metal contact
