King Engine Bearings Datsun A12/(Size +0.75mm) Main Bearing Set

When you're rebuilding the bottom end of your Datsun A12 engine, getting the main bearings right is critical. These main bearings from King Engine Bearings are a bimetal type, meaning they have an aluminum base, which helps with heat transfer and compatibility with your crankshaft. This particular set is sized at +0.75mm, so it's meant for a crankshaft that has been machined down by that amount to correct for wear or damage.

King Engine Bearings is a well-known name in engine components, and this set is built to handle the demands of an A12 engine. The bimetal construction is a popular choice for many performance and rebuild applications because it offers a good balance of strength and conformability. This means the bearing can adapt slightly to the crankshaft's surface while still providing solid support for the rotating assembly.

This main bearing set fits a range of Datsun and Nissan vehicles from the early 70s through the early 80s, including models like the Datsun 1200, 210, and B210. Make sure to confirm fitment for your specific vehicle. When installing, always refer to the manufacturer's service manual for proper torque specifications and assembly procedures.
