What is the PMaxBlack technology?

PMaxBlack is a proprietary material used by King Engine Bearings. It's a tri-metal copper-based material specifically developed to offer superior load capacity, making the bearings more durable under stress.

What does 'STD' size mean for these bearings?

STD stands for standard size. This means the bearings are designed to fit a crankshaft that is still within its original factory specifications. If your crankshaft has been machined undersize, you will need a different size bearing set.

Are these bearings suitable for a performance engine build?

Yes, the PMaxBlack technology and tri-metal copper-based construction are designed for improved load capacity, making them a solid choice for performance applications where increased stress is expected.

About this part

Product Details

King Engine Bearings has been a specialist in engine bearings since 1960, focused on supplying the highest quality bearings available. This main bearing set, part number MB7772XP, is built for your 2001-2009 Subaru Outback with the EZ30 or EZ30D engine. If you're rebuilding the bottom end of your Subaru, these bearings are a solid option to consider for improved durability and performance.

These bearings feature King's PMaxBlack technology, which is a tri-metal copper-based material designed for superior load capacity. This means they can handle more stress under demanding conditions. They also incorporate Radialock, a feature that helps achieve optimal crush height, ensuring a snug and secure fit within the engine block for consistent oil pressure and reduced wear.

This set is a standard (STD) size, meaning it's intended for crankshafts that are still within their original factory specifications. If your crankshaft has been machined undersize due to wear or damage, you would need a different size bearing. Always check your crankshaft dimensions before ordering bearings to ensure proper fitment and engine health.
