ZRP standard series H-Beam shaped Connecting Rods are manufactured from 4340 high tensile steel and they are designed for high performance and extreme durability.
The bushings are made from AMPCO 18 material, for excellent resistance to wear and fatigue and have radial groove acting as an oil reservoir. These rods have “Ribbed pin end” that minimizes pin end distortion under heavy inertial loads while saving excess weight. They are shot peened to relieve stress from the material and multi-stage heat treated to increase rigidity. Bend and twist is tightly controlled while tight tolerances in the production process, ensure a perfect fitment while optimizing the oil clearances.
Each rod includes ARP 2000 cap fasteners that are rated at 220,000 psi , optional ARP L19 material available as an upgrade and the whole kit is supplied with ARP moly and full fitting instructions
