What does the 'STDX' size mean for these bearings?

The STDX size indicates that these bearings are 0.0005 inches larger in diameter than a standard-sized bearing. This is useful for engines with slightly increased clearances or for builders who want to ensure a precise fit.

What is the pMax Black overlay mentioned in the description?

The pMax Black overlay is an advanced material applied to the bearing surface. It's designed to enhance durability and performance, especially under the higher loads and temperatures often found in performance or rebuilt engines.

Are these bearings suitable for a stock engine rebuild?

Yes, these bearings are designed as a direct replacement for stock and feature a trimetal construction with a performance-oriented overlay. They are a well-built option for both stock rebuilds and more performance-focused engine work.

About this part

Product Details

The STDX size on these King Engine Bearings means they are 0.0005 inches larger than standard, designed to take up a bit more clearance in your BMW S54B32 engine. These are connecting rod bearings, a critical part of your engine's rotating assembly that allows the connecting rod to pivot smoothly on the crankshaft. For a high-performance engine like the S54, using a well-built bearing is essential for reliability and longevity.

These bearings feature a trimetal construction with a pMax Black overlay, which is a step up from standard bearings. This advanced material helps them handle the increased loads and heat found in performance applications, offering improved durability. They are designed as a direct replacement for your stock bearings, making installation straightforward if you're rebuilding or refreshing the bottom end of your M3, Z3, or Z4.

If you're working on a performance build or a thorough engine overhaul for your 2001-2006 BMW M3, 2001-2002 Z3, or 2006-2009 Z4, these King Engine Bearings offer a solid option. They are a popular choice for those looking for a reliable bearing upgrade that can handle more demanding use than stock.
