Product Description

The Skunk2 Alpha Series Connecting Rod Set (part 306-05-1170) is built for the Honda/Acura H-series 2.2 L DOHC VTEC engines (H22A1/H22A4) found in 1993-2001 Prelude and selected Accord Type R models. These rods are crafted from premium forged 4340 chromoly steel, feature a direct straight H-beam layout for optimal strength-to-weight ratio, include dual oil passages, bronze bushings, and high-quality ARP2000 rod bolts - ready for serious performance applications.

Ideal for high-rev naturally aspirated or forced-induction H22 engine builds, the kit supports power levels up to 900+ hp when paired with a properly prepared block, pistons, valvetrain, and other engine internals. Installation demands careful assembly: verify block condition, match pistons and rods, ensure correct torqueing and balancing, and be aware of clearance for high rpm use.
