The bushings are made from AMPCO 18 material, which offers excellent resistance to wear and fatigue, and feature a radial groove that acts as an oil reservoir. They undergo shot peening to relieve internal stresses and a multi-stage heat treatment to increase their rigidity. Strict production tolerances ensure a perfect fit and optimize oil clearances. Bending and twisting are strictly controlled. Each connecting rod includes ARP 2000 bolts with a tensile strength of 220,000 psi; optionally, you can choose the ARP L19 material with a tensile strength of 260,000 psi. The complete kit is supplied with ARP moly lubricant and full assembly instructions.
