Overview

The ACL Race Rod Bearings are a set of 8 bearing halves designed for Honda/Acura K20A2/K24A engines. These tri-metal bearings are manufactured to exacting tolerances with micron precision machining to ensure consistent accuracy in wall thickness and crush. This manufacturing process guarantees reliable fit and helps maintain consistent oil clearances.

The bearings provide high strength and excellent seizure resistance, with no flash plating applied to improve bearing retention and maximize heat transfer. Available in standard, oversized (.025mm and .25mm), and extra clearance options, these bearings are essential for high-performance engine builds.
