What does the '+0.020' size mean for these bearings?

The '+0.020' indicates that these main bearings are designed for a crankshaft that has been machined down by 0.020 inches. This is a common practice during engine rebuilds to correct for wear on the crankshaft journals.

What is the CP material used in these bearings?

The CP material is a high-performance overlay developed by King Engine Bearings. It is known for offering excellent durability and wear resistance, making it suitable for engines that experience significant loads and high speeds.

Are these bearings a direct replacement for all Vortec 169 Lk5 engines?

These bearings are specifically sized at +0.020 for a machined crankshaft. You must verify that your engine's crankshaft has been machined to this exact size and that it is the correct application for your specific General Motors 169 Lk5 Vortec 16V DOHC engine before installation.

About this part

Product Details

King Engine Bearings is well-known for making solid engine components, and this Main Bearing Set is no different. This set is specifically for General Motors 169 Lk5 Vortec 16V DOHC engines and is sized +0.020 inches, meaning it's designed for crankshafts that have been machined down by that amount during an engine rebuild. Main bearings are critical for supporting the crankshaft and ensuring it spins smoothly within the engine block. They handle immense loads and high speeds, so having a well-built set like this is key to a healthy engine.

This particular set uses King's CP material, which is a high-performance overlay that offers excellent durability and wear resistance, especially in demanding applications. The +0.020 sizing indicates these are meant for a specific stage of engine rebuilding where the crankshaft journals have been turned down to compensate for wear. It's important to ensure your crankshaft has been properly measured and machined to this exact size before installing these bearings to achieve the correct clearances and oil pressure.
