SPC Performance Toyota 4RUNNER & FJ UCA (PAIR)

Correct front alignment and improve suspension clearance on a lifted Toyota 4Runner, FJ Cruiser or Lexus GX with this pair of SPC Performance adjustable front upper control arms. SPC part number 35480 combines forged-steel arm construction with adjustable ball joints to provide additional camber and caster correction beyond the factory lower control-arm adjustments.

These arms provide a front camber adjustment range of plus or minus 2 degrees and a caster range of 0 to plus 4 degrees. Built-in positive caster helps restore alignment and steering stability after lifting, while the adjustable design can help position oversized tires farther forward in the wheel opening for improved clearance.
