What does the STDX size designation mean for these bearings?

The STDX designation indicates that these bearings are 0.040 inch undersize. This is important if your crankshaft has been ground undersize during a rebuild or if you are using an aftermarket crankshaft that requires this specific bearing size.

What is the advantage of the lead-free composite material?

The lead-free composite material is an environmentally safe choice and is designed for high-performance applications. It offers a durable bearing surface that works well with various crankshaft materials and oil types, contributing to improved engine longevity.

Does this bearing set come with installation hardware?

This product is a set of connecting rod bearings only. Installation hardware, such as new connecting rod bolts or nuts, is typically sold separately and should be sourced according to your engine's service manual specifications.

Product Details

If you're rebuilding the bottom end of your Chevrolet big block engine, especially a Gen IV, V, or VI model, a solid set of connecting rod bearings is crucial. King Engine Bearings has been specializing in these critical components since 1960, focusing on supplying well-built bearings that can handle the demands of performance and daily driving alike.
