Caster Correction: IRONMAN 4X4 upper control arms are forged with 4 degrees of caster correction for ideal wheel alignment, correcting the vehicle’s geometry back to OEM specs, generating outstanding performance and ride quality.

Drop Forged Construction: Drop forged construction results in improved strength to weight ratios, increased directional strength with reduced stress concentrations in corners and filets. The precision of drop forging consistently results in superior strength, weight savings, and manufacturing tolerances when compared to machined, rolled, or other cast processes.

Hardened Zinc Coating: Wrapped in a hardened zinc coating, these UCA’s have up to 75% more corrosion resistance when compared to traditional paint or powder coating. This zinc coating provides maximum effectiveness at warding off the oxidation that typically leads to rust and corrosion.

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 doesnt allow for contaminates to be introduced into the joint with grease guns or outside environment.
