ACL Nissan CA18/C20 Standard Size High Performance Main Bearing Set

Doing an engine rebuild on your 1982-1989 Nissan Stanza, especially with a CA18 or C20 engine, means you're looking at the core components that keep everything spinning smoothly. Main bearings are a big part of that. They sit between the crankshaft and the engine block, supporting the crankshaft and allowing it to rotate with minimal friction. When you're building or refreshing an engine, especially one that might see spirited use, a well-built set of main bearings is essential for reliability and performance.

This set from ACL is built to handle the demands of performance engines. They are a standard size, meaning they're designed to fit a crankshaft that hasn't been machined undersize. ACL uses a tri-metal overlay on these bearings, which is a common and effective material for high-performance applications. This overlay helps to reduce friction and wear, even under higher loads and RPMs that you might encounter in a rebuilt or modified engine. They are a solid option when you need to ensure the crankshaft is properly supported and lubricated.

When you're putting an engine back together, it's important to have all the right parts. This set includes the main bearings needed for your engine. Always refer to your vehicle's service manual for the correct installation procedures and torque specifications to ensure everything is set up properly.
