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