What type of engine load is this bearing set best suited for?

This King Engine Bearings set is specifically designed for low to medium-load engines. The lead-free composite material is well-suited for applications that are not subjected to extreme stress or high RPMs.

What does 'bi-metal aluminum material' mean for these bearings?

Bi-metal construction typically means there are two layers of material. In this case, it's an aluminum alloy backing with a specific bearing material on the surface that contacts the crankshaft. This design helps manage heat and wear.

Are these bearings a direct replacement for all GM 400ci engines?

While these bearings fit a broad range of GM 400ci 6.6L V8 OHV vehicles, it's always best to verify the specific fitment for your vehicle's year, make, and model using the provided fitment data to ensure compatibility.

About this part

Product Details

This set of five crankshaft main bearings from King Engine Bearings uses a lead-free, environmentally safe composite material. This bi-metal aluminum construction is a solid choice for engines that aren't under extreme load, like many stock or mildly modified General Motors 400 cubic inch (6.6L) V8 applications.

King Engine Bearings has been specializing in engine bearings since 1960, focusing on supplying well-built components. This particular set is designed to fit a wide range of GM vehicles from the early 1970s through the early 1980s, including popular models like the Chevrolet C10, GMC C1500, and Pontiac Catalina. When rebuilding or refreshing your engine, using bearings made with a specific material composition can help ensure proper oil clearance and long-term performance.
