What is the STDX overlay on these bearings?

The STDX overlay is a tin-based material developed by King Engine Bearings. It is known for its improved embeddability, meaning it can better conform to minor imperfections in the crankshaft surface, and its compatibility with crankshafts.

What does '32 Uppers' mean in the product name?

The '32 Uppers' designation refers to a specific design for the upper half of the connecting rod bearing. This often indicates an optimization for oil flow and load distribution tailored for high-performance racing applications.

Are these bearings suitable for a stock engine rebuild?

While these bearings are well-built, the STDX overlay and '32 Uppers' designation suggest they are optimized for high-performance or racing applications. For a standard stock rebuild, you might consider a different bearing series unless the engine build specifically calls for these characteristics.

About this part

Product Details

King Engine Bearings is well-known for making solid engine components, and this conrod bearing set is a prime example of their work for high-performance Chrysler applications. This set is specifically designed for 361ci and 383ci engines, often found in drag racing or other demanding builds where reliability under extreme stress is crucial.

These bearings feature a specialized STDX overlay, which is a tin-based material that offers improved embeddability and compatibility with crankshafts. The '32 Uppers' designation indicates a specific design for the upper half of the connecting rod bearing, often optimized for oil flow and load distribution in racing engines. This attention to detail helps ensure consistent oil film thickness and reduces friction, which is vital for preventing bearing failure at high RPMs and under heavy loads.

When rebuilding a performance engine like a Chrysler 361 or 383, using bearings that can handle the increased forces is essential. This set from King is built to meet those demands, offering a well-built option for racers and serious engine builders.
