Hot Rods Bearing - 34 x 43 x 21 KU

This is a Hot Rods engine bearing, part number B163. It's a KU bearing, meaning it's designed for the big end of your connecting rod. If you're rebuilding an engine, especially a performance or high-mileage one, getting the right bearings is crucial for smooth operation and longevity. These bearings are built to handle the stresses of the rotating assembly.

What sets these bearings apart is their construction. They are case hardened, which means the outer layer is made tougher to resist wear and deformation under load. On top of that, they have a silver coating. This coating helps with initial break-in and provides an extra layer of protection, especially during those critical first few hours of engine operation. The dimensions are 34mm ID, 43mm OD, and 21mm width, so make sure these match your specific application's requirements.
