Product Description
If you're lifting your Toyota 4Runner, FJ Cruiser, or Lexus GX and want to unlock the full performance potential of your suspension, the SPC Adjustable Upper Control Arms (PN 25480) are a game changer. These aren’t your average UCAs—SPC has engineered these to improve suspension geometry, restore factory ride quality, and maximize off-road capability.
Perfectly suited for lifted 4th Gen 4Runners, FJ Cruisers, and GX470/GX460s, these upper control arms allow for proper alignment after a lift, more suspension travel, and better clearance around your coil bucket. Whether you're tackling tight switchbacks in Moab or daily driving with larger tires, SPC’s forged steel control arms offer the strength, adjustability, and articulation serious off-roaders demand.

Why We Love It
Most factory Toyota upper control arms max out around 68° of movement—SPC blows that out of the water with 80° of unrestricted articulation, allowing for more droop travel and better shock performance. That added flexibility helps your suspension work the way it's supposed to.
If you've lifted your 4Runner or added oversized tires, these UCAs correct your alignment, prevent uneven wear, and center your tires more effectively in the wheel well—minimizing the need for fender trimming.
Plus, they’re quieter and longer-lasting than uniball setups thanks to the rubber-isolated bushings and greasable ball joints. These are perfect for off-road rigs that still see daily driver duty.
