ACL Honda 4 H22A4 2156cc Race Series Engine Connecting Rod Bearing Set

You get a full set of connecting rod bearings in this kit, which means one box handles the whole job for your engine. These are the ACL Race Series bearings, built for performance and durability. They are a .50mm (0.020 inch) undersize, meaning they're intended for crankshafts that have been machined down to match this size. This is a common step when rebuilding an engine to ensure a perfect fit and optimal oil clearance.

ACL has been making engine bearings for a long time, and their Race Series is well-known for being a solid option when you need something more robust than stock. They use a special overlay material that's designed to handle higher loads and temperatures, which is crucial if you're pushing your engine hard or if it's been rebuilt with performance in mind. The .50mm undersize is important – make sure your crankshaft has been properly measured and machined to this specific size before installing these bearings. Getting the oil clearance just right is key to engine longevity and performance.
