The Ironman 4x4 upper control arms (UCAs) are engineered for direct replacement of the OEM UCAs. Ironman 4x4 upper control arms are forged with four degrees of caster correction for ideal wheel alignment, correcting the vehicle’s geometry back to OEM specs, generating outstanding performance and ride quality. The Pro Forge off-road upper control arms feature drop forged construction, resulting in improved strength to weight and increased directional strength while reducing stress 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.
