Built with enhanced tri-metal, King XP-Series main bearings have a layered copper lead construction, with a nickel plate barrier and 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: an amazing +/- .0001 in. The XP-Series main bearings are narrowed for large radii crankshafts and feature enlarged, chamfered oil holes with full, 3/4 in., or 1/2 in. grooving for improved oiling. They deliver consistent and reliable performance with a high-load capacity. These race-only Xtreme Performance (XP-Series) Tri-Lecular main bearings are proven track-tough to handle the ground-shaking power of your race engine. Hundreds of sets are available; order the bearings recommended for your vehicle.

ACL Performance offers Race Series rod bearing sets for a wide range of vehicles. These high performance tri-metal engine bearings are designed to withstand higher RPM conditions. They feature a high-strength overlay plate with reduced thickness for improved fatigue properties. Select the crankshaft undersize and quantity recommended for your year/make and engine application. Additional details: * Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing. * Increased crush for improved bearing retention * Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing * Increased eccentricity to compensate for bore distortion at high RPM and to assist in the formation of hydrodynamic oil films * 3/4 in. grooved main bearings to optimize bearing load carrying surface area and oil flow to the conrod bearings * Tight consistent wall tolerances to help you maintain consistent clearances * Enlarged ID chamfers on bearing edges (where required) to accommodate large fillet radius on performance crankshafts

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 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.

For some engines, the softer and more conformable nature of aluminum is preferable to the stiffer characteristics of the steel backings used for many bearings. Clevite AL-Series main bearings offer the features found in OE-type aluminum bearings, combined with the distinct advantages of proven Clevite know-how. That includes things such as carefully chosen eccentricities tailored to the application, and that means solid, reliable performance. Clevite AL-Series main bearings are a great choice for anything from OEM-style rebuilds to mild performance applications. Clevite recommends these main bearings for most engines using a cast crankshaft.
