0721 TUNDRA PRO FORGE UPPER CONTROL ARMS

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 results in improved strength to weight ratios, increased directional strength with reduced stress concentrations in corners and filets. Wrapped in a hardened zinc coating, these UCAs have up to 75% more corrosion resistance when compared to traditional paint or powder coating. They use OEM style ball joints and bushings that are tested and manufactured to strict Japanese specifications.
