Clevite H-Series main bearings were developed primarily for NASCAR racing, but are well suited to other types of competition engines as well. They're especially good for engines that run at medium-to-high revs. They have steel backings with carefully selected overlays and a high crush factor, plus a medium level of eccentricity. H-Series bearings have enlarged chamfers at the sides for greater crank-fillet clearance and are made without flash plating for better seating. They are also available with either 180 degree or 360 degree oil grooves, as well as an extra 0.001 in. of clearance.

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.

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.

King HP-Series rod bearings were developed mainly for drag race applications needing a material harder than the Babbitt top layer. These applications demanded a structure that could withstand high loads for short durations and still offer higher embeddability and compatibility. In response, King developed the HP-Series, featuring the Alecular metal structure. The HP-Series is also suited for many performance applications with nodular cast iron crankshafts, such as street, strip, and some levels of Circle Track racing. Order the set recommended for your vehicle. HP-Series bearings are particularly suitable for the following cases: * When a tri-metal bearing's Babbitt overlay extrudes over the sides, migrates to one end, or is physically removed by the crankshaft * When the intermediate layer of a tri-metal bearing is exposed, damaging the crank journal and requiring expensive grinding or replacement * When contaminants enter the oil stream, scratching and damaging the crankshaft journals

King introduces the new solution for the aftermarket demand of superior service life and performance in modern engines. The King MC-Series rod bearings were engineered in the wake of ongoing internal combustion engine development—resulting in ever-decreasing minimum oil film thickness values; higher cylinder pressures, temperatures and loads; smaller load carrying bearing surfaces; and lighter components. Additionally, "start/stop" technology produces more frequent mixed lubrication and metal-to-metal contact conditions. The new King MC-Series rod bearings feature a nano-composite polymer coating, known as K-340. It's designed for applying over relatively hard substrates: bronze, aluminum alloys, sputter overlay, and King silver overlay. These bi-metal silicone aluminum sets are available in different sizes for fitment on countless car and truck applications.
