Product Details

Already rebuilt your engine or looking to do a refresh on your 1987-1993 Mazda B2200? This set of ACL connecting rod bearings is a key component for ensuring your engine runs smoothly and lasts. These bearings sit between the connecting rod and the crankshaft, allowing the rod to spin freely while handling the immense forces generated during combustion.

They are made with a specific overlay material designed to withstand the constant friction and pressure, helping to protect your crankshaft from damage. When you're rebuilding an engine, using bearings that are the correct size and made from durable materials is crucial for long-term reliability. This set is designed to fit right into your Mazda's connecting rods, making installation straightforward for a professional or experienced DIYer.
