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 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.

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.
