Overview
Caster Correction: IRONMAN 4X4 steel upper control arms are designed for ideal wheel alignment, correcting the vehicle’s geometry back to OEM specs, and generating outstanding performance and ride quality.
Chromoly Steel Construction: Made from high-quality chromoly steel results in improved strength and increased directional strength with reduced stress concentrations in corners and filets.
OEM Ball Joints: We use OEM-style ball joints and bushings that are tested and manufactured to strict Japanese specifications that are readily available at every dealership and parts store. They feature a fully hardened stud bound in a watertight sealed machined housing which doesn’t allow for contaminants to be introduced into the joint with grease guns or the outside environment.
