ProForge Upper Control Arms Suited For 2003+ Toyota 4Runner

The Ironman 4x4 upper control arms (UCAs) are engineered for the 4runner, Lexus GX470, and GX460 to directly replace the OEM UCAs.

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.

The ProForge UCAs feature drop forged construction resulting 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 in strength, weight savings, and manufacturing tolerances when compared to machined, rolled, or other cast processes.

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.

We use OEM style ball joints and bushings that are tested and manufactured to strict Japanese specifications that are at every dealership and parts store. They feature a fully hardened stud bound in a watertight sealed machined housing which doesn’t allow for contaminates to be introduced into the joint with grease guns or outside environment.

These feature packed control arms when paired with our suspension kits translate into unmatched off-road performance, and on-road ride quality for your rig.
