King Engine Bearings Nissan CA16DET/CA18DET/CA20ET (Size STD) Performance Main Bearing Set

These King Engine Bearings main bearings use a Trimetal pMax Black construction, a design choice that helps them handle the increased loads often seen in performance applications for Nissan CA16DET, CA18DET, and CA20ET engines. When you're rebuilding the bottom end of one of these engines, especially if it's destined for more demanding use, the main bearings are critical for keeping the crankshaft properly supported and aligned. King has been making bearings for a long time, and their focus on materials and design means these are a solid option for your build.

The pMax Black material is a layered composite that's known for its strength and ability to manage oil film under pressure. This means the bearing can maintain a protective layer between itself and the crankshaft journal, reducing wear and friction. Since these are standard size (STD), they are intended for crankshafts that are still within their original factory specifications, without any machining or grinding needed for undersize or oversize applications. This makes installation more straightforward if your crank is in good shape.

When installing these bearings, it's important to ensure your crankshaft journals are clean and smooth, and that you follow the correct torque specifications for your engine. Proper assembly is key to getting the most out of these well-built components and ensuring the longevity of your engine rebuild.
