Suzuki 1.3L Hayabusa Gen.2 H-Beam Connecting Rods are crafted from 4340 high tensile steel, designed for high performance and extreme durability. The bushings are made from aluminum-silicon/bronze material with a radial groove acting as an oil reservoir. These rods feature a "Ribbed pin end" to minimize pin end distortion under heavy inertial loads while reducing weight. They are shot peened to relieve stress and undergo multi-stage heat treatment to enhance rigidity. Tight production tolerances ensure perfect fitment and optimized oil clearances, with controlled bend and twist. Each rod includes ARP 2000 cap fasteners rated at 220,000 psi, with an optional ARP 625 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 applications
• Grooves in Thrust Face for weight reduction
