What is the STDX size designation?

The STDX size designation means these bearings are 0.001 inch undersize. This is a common size used when the crankshaft has been machined or ground undersize during an engine rebuild.

What is the pMax Black racing line?

The pMax Black racing line from King Engine Bearings features an advanced tri-metal construction with a special overlay. This design offers improved strength and wear resistance compared to standard bearings, making them suitable for performance applications.

Do these bearings come with installation hardware?

This product is a set of main bearings only. Installation hardware, such as main cap bolts or bearing retaining clips, are typically sold separately and should be sourced according to the vehicle manufacturer's specifications.

About this part

Product Details

If you're rebuilding the engine in your 1995-2010 Dodge Neon SRT-4, Chrysler PT Cruiser, or Jeep Wrangler, these King Engine Bearings performance main bearing set (part number MB5270XPSTDX) are a solid option. They are designed for the 2.4L EDZ SRT-4 turbo engine and are part of King's pMax Black racing line, offering an improved tri-metal construction for demanding applications.

These bearings feature a special pMax Black tri-metal overlay, which is a step up from standard bearings, providing enhanced durability and reduced friction. This makes them a popular choice when you need a well-built bearing that can handle the stresses of performance driving or a full engine rebuild. The STDX size indicates they are 0.001 inch undersize, which is common for engine machining and ensures a precise fit after block work.

When installing these bearings, it's crucial to ensure your crankshaft journals are properly machined and polished to the correct specifications, as these are performance-oriented components. Always refer to the manufacturer's installation instructions for detailed guidance.
