What does STDX sizing mean for these bearings?

STDX sizing means these bearings are 0.001 inch undersize compared to standard specifications. This can be useful for crankshafts that have been reconditioned or require slightly tighter bearing clearances for optimal performance.

What is the pMax Black trimetal construction?

pMax Black is a specialized trimetal material developed by King Engine Bearings. It's designed to offer improved load-carrying capacity and better oil film support, especially under the higher stress and temperatures encountered in performance or race applications.

Are these bearings suitable for a daily driver?

While these are race bearings designed for demanding use, they can be used in a daily driver if the engine is built or modified for performance. For a stock daily driver, standard bearings might be a more appropriate choice unless specific performance goals are being pursued.

About this part

Product Details

If you're rebuilding the engine in your 2001-2009 Subaru Outback, especially for performance applications, paying close attention to your connecting rod bearings is crucial. These King Engine Bearings are designed for the EZ30 and EZ30D engines, offering a step up from standard components. They are a race bearing variant, featuring a unique pMax Black trimetal construction that's built for demanding use.

The STDX sizing indicates these bearings are 0.001 inch undersize, which can be helpful if your crankshaft journals require a slightly tighter clearance or have been reconditioned. The pMax Black material is a specialized trimetal formulation developed by King to handle higher loads and temperatures often found in performance or racing engines. This construction aims to provide improved durability and consistent oil film support under stress.

When installing these bearings, it's always a good idea to refer to the manufacturer's specifications for proper clearance and torque settings. Ensuring your crankshaft journals are clean and within tolerance will help these bearings perform as intended.
