ACL Performance Race Series Main Bearing Sets
ACL Performance Race Series main bearing sets deliver everything performance bearings should be by utilizing design, metallurgy, engineering, precision quality control, and of course, years of knowledge and experience. Main bearings feature multi-layered tri-metal copper alloy construction that blends characteristics to provide high strength and excellent seizure resistance. They are manufactured to exact tolerances ensuring a reliable fit and helping to maintain consistent clearances. Main bearings are augmented with extended grooves, as well as other bearing enhancements, like increased crush, bearing eccentricity, and enlarged I.D. chamfers. ACL Performance Race Series main bearing sets are produced in standard and extra clearance versions, with or without friction reducer coating, and with modifications to meet specific build requirements, such as narrowed bearings that permit additional edge clearance when running crankshafts with exceptionally large fillet radii. In the heat of competition proven technology always comes through. The choice for your build should always be ACL Performance Race Series engine bearings. Choose the main bearing set designed for your vehicle.

King MC-Series Rod Bearings
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.

Sealed Power MA Series Main Bearings
These Sealed Power MA Series main 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 whose surface 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 control of wall variance. It also helps to minimize debris embedding, which can score the crank's surface.

Clevite AL-Series Main Bearings
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.

Enginetech Engine Crankshaft Thrust Washers
Enginetech offers engine crankshaft thrust washers for a wide range of applications. These precision-engineered, wearable components are designed to control crankshaft end-float (axial forward/backward movement) in engines. They protect expensive crankshafts and engine blocks from damage by providing a dedicated wear surface, meeting or exceeding OE specifications. Order the washers recommended for your vehicle. Key features and functions: * Prevent damage: These washers take the wear, preventing the crankshaft counterweights from striking the cylinder block, which can cause catastrophic engine failure * Control end-float: They manage the forward/backward movement caused by clutch operation in manual vehicles or torque converter loads in automatics * Maintain alignment: They ensure the crankshaft remains in the correct position for proper connecting rod alignment, preventing binding, jamming, or uneven piston wear * Material quality: Often manufactured from durable, high-quality bronze or bimetallic materials that can handle high-load, high-friction scenarios * Using Enginetech thrust washers ensures precise clearances, which is crucial for oil pressure retention and preventing crankshaft "walking"
