Honda OEM Connecting Rod Bearings - NSX, 1991-05

Honda genuine OEM connecting rod bearings. 3.0L and 3.2L connecting rod crankshaft pins are different in size. Sold each (twelve bearings required per engine). Imported from Japan (bearing selection is limited / discontinued in the USA).

Color coding: the factory engine bearings are color coded to designate thickness. Red is thinnest, blue is thickest. The bearing colors used when the engine assembly was assembled new is marked with codes on the crankshaft and connecting rod. Use the factory service manual (search for "NSX service manual PDF" in a web search) to determine which colors were used by the factory when the engine was new. It should be considered that bearing thickness likely needs to be adjusted on the engine when rebuilt to adjust for wear to achieve factory recommended oil clearance. Consult factory manual for procedure.
