I-Beam Heavy Duty Connecting Rods for Suzuki 1.3L Hayabusa Gen.2

The I-Beam “Heavy Duty” series connecting rods are designed specifically for high horsepower and boost applications in the Suzuki 1.3L Hayabusa Gen.2. Constructed from premium 4340-EN24T high tensile steel, these rods feature an optimized shape for enhanced performance and exceptional durability.

The bushings are made from an aluminum-silicon/bronze alloy and include a radial groove for oil reservoir. Each rod undergoes shot peening to relieve material stress and is multi-stage heat treated to maximize rigidity. Tight tolerances in the production process ensure a precise fit while optimizing oil clearances, with controlled bend and twist characteristics.

Each rod is equipped with 3/8 ARP 2000 cap fasteners rated at 220,000 psi, with an optional upgrade to ARP L19 material rated at 260,000 psi. The complete kit includes ARP moly and comprehensive fitting instructions.

Additional Machining Processes

• Dowel sleeves for perfect fit and accurate re-assembling
• Lipped cap relief for improved big-end integrity in extreme applications
• Grooves in thrust face for weight reduction
