Inline Four now offers OEM Honda connecting rod bearings for your engine building needs. We do so many engine builds, that we have many of these bearings in stock. Just like the GSR/ITR rod bearing, the K-series rod bearings also feature the friction reducing coating that consists of molybedynum. You can also see how much thinner the K-series rod bearings are. The lesser surface area, means less friction, but also at the expense of less strength. That is why, when you go forced induction or a very aggressive all-motor setup, upgrading the connecting rods is never a bad idea.
Below is a chart of all the colors offered by Honda and their respective thicknesses. The top of the chart is the thickest bearing and the bottom is the thinnest bearing. You can "half-shell" and use two different colors to achieve the desired clearance. However, we suggest not to jump up or down more than one color.
Rod bearing thickness by color
