Forged connecting rods Suzuki - 1.3L Hayabusa Gen.2 - H-beam - 18 mm pin for forged pistons

Set of 4 ZRP forged connecting rods in 4340 steel for Suzuki 1.3L Hayabusa Gen.2 (2008-2012), H-beam, 18 mm piston pin.

The manufacturer rates this rod for naturally aspirated use. The H-beam profile favours light weight and rigidity along the main axis, a coherent choice for a high-revving atmospheric engine.

Torque and bolt stretch

ARP 2000 bolts are tightened to 40.7 Nm, or by stretch control between 0.140 and 0.152 mm. The optional ARP L19 bolts are tightened to 54.2 Nm, or by stretch control between 0.127 and 0.140 mm. These bolts are 5/16": ARP 2000 suits builds up to 150 hp per cylinder and 8,500 rpm, ARP L19 up to 200 hp per cylinder and 10,000 rpm. Measuring stretch with a dial indicator remains the most reliable method: it reflects the real tension in the bolt, whereas torque depends on thread friction.

Kit supplied complete with bolts, for all four cylinders of the Hayabusa Gen.2 engine. Check the manufacturer's intended use before fitting: this reference is built for naturally aspirated engines.
