What does the 0.020 inch undersize mean for these bearings?

The 0.020 inch undersize specification means these bearings are intended for use with a crankshaft that has been machined down by 0.020 inches. This ensures proper clearance and fitment when rebuilding or modifying an engine.

What is the Alecular material used in these bearings?

Alecular is King Engine Bearings' bi-metal material specifically developed for their racing line. It's chosen for its strength and performance characteristics in demanding engine applications.

Are these bearings suitable for a stock engine rebuild?

These are performance rod bearings from King's racing line and are sized 0.020 inch undersize. They are best suited for performance builds where the crankshaft has been specifically machined to accept this size, rather than a standard stock rebuild.

About this part

Product Details

This is a set of performance connecting rod bearings from King Engine Bearings, specifically sized 0.020 inch undersize. These bearings are part of King's Alecular racing line, designed for engines that see demanding use. They are intended for Chevrolet Small Block engines like the 307ci and 350ci, as well as Gen III and Gen IV LS engines found in a wide range of vehicles.

The Alecular material is a bi-metal construction that King uses for their racing applications, offering a strong option for performance builds. Because these bearings are 0.020 inch undersize, they are meant to be used with crankshafts that have been machined down by 0.020 inches to ensure a proper fit and oil clearance. This is a common practice when rebuilding or modifying engines for improved performance and durability.
