What does the '001' size designation mean for these bearings?

The '001' in the part number indicates that these bearings are 0.001 inches undersize compared to the standard size. This means they are intended for use with crankshaft journals that have been machined down by 0.001 inches to achieve a precise fit and optimal oil clearance during an engine rebuild.

What is the benefit of bi-metal aluminum material for rod bearings?

Bi-metal aluminum construction is popular for performance rod bearings because it offers a good balance of strength and conformability. This material helps the bearing adapt to the crankshaft surface while maintaining its structural integrity under high loads and temperatures.

Are these bearings compatible with all LS engines?

These bearings are specifically designed for Chevrolet SBC Gen III/IV LS engines with displacements of 4.8L, 5.3L, 5.7L, and 6.0L. While they fit many vehicles equipped with these engines, it's always best to verify fitment for your specific vehicle's engine code and year.

About this part

Product Details

This is a set of performance connecting rod bearings from King Engine Bearings. You get the bearings needed to replace the ones on your connecting rods, specifically sized at 0.001 inches undersize for a precise fit. These are designed for Chevrolet LS engines, covering popular displacements like the 4.8L, 5.3L, 5.7L, and 6.0L found in many trucks and performance vehicles.

King Engine Bearings specializes in making just bearings, and they've been doing it since 1960. This set uses a bi-metal aluminum material, which is a solid choice for high-performance applications. They're also lead-free, making them an environmentally safer option. The 0.001 inch undersize means they're intended for applications where the crankshaft journals have been machined down slightly to ensure a perfect, snug fit and optimal oil clearance.

These bearings fit a wide range of vehicles, including many Chevrolet, Buick, Cadillac, and GMC models from the 1980s through the 2010s. If you're rebuilding an LS engine and need reliable rod bearings, this set from a specialist manufacturer is a well-built option.
