What does the '+0.25' size mean for these rod bearings?

The '+0.25' indicates that these bearings are 0.25mm undersize. This means they are designed to be used when the engine's crankshaft journals have been machined down by 0.25mm to correct for wear or damage.

What type of engine is this bearing set designed for?

This rod bearing set is specifically made for Nissan KA24E and KA24DE 2.4L inline-4 engines. These engines were commonly found in models like the 240SX, Altima, Frontier, and Xterra from the late 1980s through the early 2000s.

What is the material of these bearings and why is it important?

These bearings are made from a bi-metal aluminum material with a lead-free composite. This construction is ideal for engines that don't experience extreme loads, offering good performance and durability for typical street applications.
