What does the '.010' in the part number mean for these bearings?

The '.010' indicates that these main bearings are 0.001 inch undersize compared to standard size. This is important for engines where the crankshaft has been machined down to a smaller size during a rebuild.

What is the benefit of the coating on these bearings?

The specialized coating on these King Engine Bearings helps to reduce friction and wear, particularly during the engine's break-in period and under demanding operating conditions. It also aids in preventing seizure.

What type of engines are these main bearings designed for?

These main bearings are specifically designed for Chevrolet Gen IV, V, and VI V8 engines. This covers a wide range of performance and heavy-duty applications for these engine families.

About this part

Product Details

These King Engine Bearings feature a specialized .001 inch undersize, designated by the '010' in the part number, which is crucial for engines that have been previously machined or require a tighter clearance. This set is specifically made for Chevrolet Gen IV, V, and VI V8 engines, commonly found in performance builds and heavy-duty applications. The advanced coating on these bearings helps reduce friction and wear, especially during the critical break-in period and under high-stress conditions.

King uses a unique tri-metal material construction for these main bearings, combining a steel backing for strength, a bronze interlayer for durability, and a lead-indium overlay for improved embeddability and seizure resistance. The .001 inch undersize is a precise measurement that ensures a proper fit and optimal oil clearance when the crankshaft journals have been ground down to match. This attention to detail in sizing and material science helps protect your engine's rotating assembly.

When rebuilding or refreshing your Chevrolet V8 engine, using bearings that are precisely sized and built to handle the demands of these powerful engines is essential. This set offers a well-built solution for ensuring the longevity and performance of your engine's bottom end.
