King Engine Bearings Chevrolet SBC 265Ci 283Ci 327Ci (Size STDX) Connecting Rod Bearing Set

King Engine Bearings is known for making robust engine components, and this CR803XPNDSTDX connecting rod bearing set is a prime example of their work for Chevrolet SBC engines. These bearings are designed for race applications and feature a tri-metal pMax Black construction, offering improved performance over standard bearings. They are specifically sized STDX, which is an undersize bearing, meaning it's meant for crankshafts that have been machined down to compensate for wear or previous repairs.

The pMax Black tri-metal material is a notable step up from conventional bearings, providing better load capacity and durability, which is crucial when you're pushing an engine hard. This set is an optional upgrade from their CR803AM race bearings, suggesting a high level of performance tuning is intended. If you're rebuilding a Chevrolet SBC engine, especially for performance use, these bearings are built to handle the demands.

This set fits a wide range of Chevrolet SBC engines found in vehicles like the Chevrolet Bel Air, Impala, and Corvette from the mid-50s through the late-60s, as well as many other makes and models from that era. Always ensure your crankshaft journals have been machined to the STDX undersize specification before installing these bearings.
