Clevite Subaru EJ Series 1990-2005 Main Bearing Set

This Clevite main bearing set is built with a 0.025 inch undersize, meaning it's designed for crankshafts that have been machined down to match this specific size during an engine rebuild. These bearings are crucial for supporting the crankshaft within the engine block, allowing it to spin freely while handling the immense forces generated during combustion. When you're rebuilding the bottom end of your Subaru EJ series engine, getting the right bearings is key to ensuring long-term reliability and performance.

Clevite uses a multi-layer bearing material that includes a steel backing for strength, a bronze-aluminum alloy intermediate layer, and a lead-tin-copper overlay for excellent wear resistance and compatibility with crankshaft surfaces. This combination helps to manage heat and reduce friction, which are critical factors in preventing premature engine wear. The 25mm main journal size is specific to many Subaru EJ engines, so ensuring you have the correct size is vital for a proper fit and function.

When installing these bearings, it's important to follow the manufacturer's recommended torque specifications and lubrication procedures. Proper installation ensures that the bearings achieve their intended clearance and can effectively do their job. This set is a solid option for anyone looking to restore or rebuild their Subaru's engine with reliable components.
