What is the STDX size designation?

The STDX designation indicates that these bearings are 0.001 inch undersize compared to standard size. This is often used when the crankshaft journals have been machined undersize during an engine rebuild.

What makes these 'race bearings'?

These are considered race bearings due to their trimetal pMax Black construction, which offers improved lubrication and wear resistance for high-performance or demanding engine applications compared to standard bearings.

Are these bearings compatible with a standard crankshaft?

These bearings are 0.001 inch undersize (STDX). If your crankshaft journals are at standard size, you would typically need standard size bearings. These are intended for use with crankshafts that have been machined to an undersize specification.

About this part

Product Details

This product is a set of King Engine Bearings performance rod bearings, specifically the CR4065XPSTDX model. You get the connecting rod bearings needed for your engine rebuild. These are designed for the Nissan KA-24E engine, often found in vehicles like the Nissan 240SX, Altima, and Frontier.

These bearings are a trimetal pMax Black race bearing, which is an updated design from their previous CR4065AM race bearings. They are built for demanding applications where improved lubrication and wear resistance are important. The STDX designation means these bearings are 0.001 inch undersize, which can be useful for engines that have had their crankshaft journals ground undersize during a rebuild.
