King Engine Bearings Nissan Yd22/Yd25 (Size +0.25mm) Main Bearing Set

This is a main bearing set from King Engine Bearings, specifically designed for Nissan YD22 and YD25 engines. These bearings are a crucial part of your engine's rotating assembly, supporting the crankshaft and ensuring it spins smoothly within the engine block. This particular set is sized at +0.25mm, meaning it's intended for use when the crankshaft journals have been machined to this size during an engine rebuild.

King Engine Bearings uses a bimetal construction with an aluminum silicon base for these bearings. This material combination is chosen for its good load-carrying capabilities and wear resistance, which are essential for the high-stress environment inside an engine. When you're rebuilding an engine, using bearings that are precisely sized and made from durable materials like these helps ensure proper oil clearance and long-term reliability.
