Product Description

The Skunk2 Alpha Series Connecting Rod Set (part 306-05-1150) is purpose-built for Honda/Acura K-Series 2.4 L engines (K24A/Z families) and designed for high-performance and high-rev applications. With its forged 4340 chromoly steel H-beam design, dual oil-passage architecture, and high-clamp rod bolts, this set offers strength and reliability when building for 900+ hp or demanding performance builds.

Ideal for naturally aspirated or forced-induction K24 engines with upgraded bottom-end components, these rods deliver enhanced valvetrain and crank-train stability. Installation requires proper block inspection, balancing, correct piston-pin compatibility, precise torqueing of bolts, and matching with other upgraded components for best results.
