Product Details

When you're rebuilding the bottom end of your Nissan L20B, Z20, Z22, or Z24 engine, a solid set of main bearings is crucial. This set from King Engine Bearings includes the main bearings you need to get your crankshaft properly seated and spinning smoothly. They are built with a bimetal construction, meaning they have an aluminum base which helps with heat dissipation and load-carrying capacity.

This particular set is sized at +0.75mm, which is important if your crankshaft journals have been machined undersize during a previous rebuild or to correct wear. King Engine Bearings is a well-known name in the engine component world, and these bearings are a popular choice for many engine builders looking for a reliable replacement. They fit a range of Nissan vehicles, including models like the 720 pickup, D21, and the Pathfinder from the late 70s through the late 80s.
