What does the STDX size mean for these bearings?

The STDX size means these rod bearings are 0.040 inch undersize. This is important if your engine's crankshaft has been machined or ground down, as it ensures the correct oil clearance is maintained.

What is the pmax black racing line?

The pmax black racing line represents King Engine Bearings' performance-oriented offerings. These bearings are an updated option compared to their CR4017AM race bearings, suggesting improvements in materials or design for demanding applications.

Are these bearings suitable for a stock engine rebuild?

While these are performance bearings, they can be used in a stock engine rebuild if the crankshaft has been machined to the STDX undersize. For a standard rebuild with an unmachined crankshaft, you would typically look for standard size bearings.

About this part

Product Details

King Engine Bearings is well-known for making solid engine components. This set of performance rod bearings, part number CR4017XPSTDX, is their pmax black racing line, an updated option over their CR4017AM race bearings. These are designed for Opel 1.8 and 2.0 X18/20XE engines, and also fit a range of other vehicles like the Buick Skyhawk, Chevrolet Malibu, and Pontiac Sunbird.

These bearings are built with a tri-metal construction, which is a popular choice for performance applications because it offers a good balance of strength and conformability. The STDX size indicates they are 0.040 inch undersize, which is important to note if you're rebuilding or working with an engine that has been previously machined. Using the correct bearing size is crucial for maintaining proper oil clearance, which directly impacts oil pressure and engine longevity.
