King Engine Bearings Ford 122 Ci Pinto (Size +0.25mm) Main Bearing Set

These main bearings are 0.25mm (0.010 inches) larger than stock, designed to fit Ford 122 cubic inch Pinto engines. When rebuilding or refreshing an engine, especially one where the crankshaft has been ground undersize, using bearings with the correct undersize is crucial for proper oil clearance. King Engine Bearings uses a high-performance overlay material that's bonded to a steel-backed structure, offering a durable surface that can handle the demands of engine operation. This construction helps ensure consistent oil film thickness, which is vital for protecting the crankshaft and extending the life of your engine.

The CP designation in the part number indicates King's high-performance overlay, which is a multi-layer material designed for improved wear resistance and load-carrying capacity. This means these bearings are built to maintain their integrity under the stresses of regular driving. Proper installation is key; ensure your crankshaft journals are clean and within the specified tolerance for these +0.25mm bearings to achieve the correct oil clearance, which is typically detailed in your engine's service manual.
