Honda F20 H-Beam De-Stroke Connecting Rods

Manufactured from 4340 high tensile steel, these connecting rods are designed for high performance and extreme durability. The "Ultra-Lightweight" design combines lightweight performance with proven reliability at extended rpm. Featuring a Tapered Pin End, they are compatible with OEM pistons. The bushings are made from aluminum-silicon/bronze material with a radial groove acting as an oil reservoir. The "Ribbed pin end" minimizes pin end distortion under heavy inertial loads while saving excess weight. Shot peened to relieve stress and multi-stage heat treated to increase rigidity, these rods ensure a perfect fitment with optimized oil clearances. Bend and twist are tightly controlled. Each rod includes ARP 2000 cap fasteners rated at 220,000 psi, with an optional ARP L19 material upgrade available.

Additional Machining Processes

• Dowel sleeves for perfect fit and accurate re-assembling
• Lipped Cap Relief for improved big-end integrity at extreme application
• Grooves in Thrust Face for weight reduction
• Tapered Pin End – Also suitable for OEM pistons
