What does the +1.0mm sizing mean for these bearings?

The +1.0mm sizing indicates that these bearings are intended for use when the engine's crankshaft journals have been machined down by 1.0mm. This is typically done to clean up wear or damage on the crankshaft during an engine rebuild. It's crucial to match the bearing size to the machined journal size for correct oil clearance.

What is the construction of these main bearings?

These main bearings feature a bimetal construction, which means they have an aluminum base. This type of construction is well-suited for main bearing applications, providing good performance and durability within the engine.

Are these bearings a direct replacement for all Nissan engines?

No, these bearings are specifically designed for Nissan engines with L20B, Z20, Z22, and Z24 engine codes. While they fit a variety of Nissan vehicles using these engines, they are not a universal fit for all Nissan models or engine types.

This set is specifically sized at +1.0mm, meaning it's intended for use when the crankshaft journals have been machined down by 1.0mm to clean up wear or damage. It's important to match the bearing size to the machined journal size for proper oil clearance and engine health.
