What does the '+0.50mm' size mean for these bearings?

The '+0.50mm' indicates that these are undersize bearings. They are intended for use when the engine's crankshaft has been machined down by 0.50mm to correct for wear or damage. It's crucial to measure your crankshaft to ensure it has been machined to this specific size before installation.

What is the Babbitt overlay and why is it important?

Babbitt is a soft metal alloy that forms the bearing surface. The enhanced Babbitt overlay on these King bearings helps to provide a smooth surface for the crankshaft to spin against, improving oil film retention and reducing friction. This is key for protecting your engine components.

Are these bearings suitable for high-performance or racing engines?

These bearings are described as ideal for medium-load engines. While well-built, they are not specifically marketed for extreme high-load racing applications. For those, you might need to consult King's performance-specific bearing lines.

About this part

Product Details

If you're rebuilding the bottom end of a Nissan VQ40DE engine, you need a solid set of main bearings. This set from King Engine Bearings is specifically designed for that job, and it's a +0.50mm undersize, meaning it's meant for crankshafts that have been machined down by 0.50mm. King has been specializing in bearings since 1960, so they know what it takes to make a reliable component for your engine.

These bearings use a tri-metal copper-based material with an enhanced Babbitt overlay, which is a popular choice for medium-load engines like those found in many trucks and SUVs. This construction helps ensure good oil film retention and wear resistance, critical for the longevity of your crankshaft and main journals. They are well-built to handle the demands of daily driving and moderate use.

This set fits a range of vehicles including the Nissan Frontier, Pathfinder, and Xterra, as well as the Suzuki Equator. Always ensure your crankshaft has been properly measured and machined to the correct undersize before installing these bearings.
