138.00mm x 21.00mm
The I-Beam “Heavy Duty” series Connecting rods for Honda B18C aimed for the High Hp/Boost applications. Built from the finest raw materials 4340-EN24T high tensile steel with a specially optimized shape for high performance and extreme durability. The C-C length has been increased with an extra 5.00mm to make these rods ideal for “Long-Rod” applications. The bushings made from Aluminum – silicon/ bronze alloy and have radial groove for oil reservoir. They are shot peened to relieve stress from the material and multi-stage heat treated to increase rigidity. The tight tolerances in the production process, ensure a perfect fitment while optimizing the oil clearances. Bend and twist is tightly controlled.
Each rod includes 3/8 ARP 2000 cap fasteners that are rated at 220,000psi, optional ARP L19 material 260.00psi available as an upgrade and the whole kit is supplied with ARP moly and full fitting instructions.
