Whiteline Front Upper Control Arms (KTA249) for 2003-2023 Toyota 4Runner, FJ Cruiser & Lexus GX470

Fits select 2003-2023 Toyota 4Runner, FJ Cruiser, and Lexus GX470.

A common challenge with modern independent front suspension (IFS) 4WDs is the limited factory adjustment range for wheel alignments, especially once the vehicle is lifted by 1 inch or more. The Whiteline offset Upper Control Arms (UCA) provide an all-in-one solution for vehicles lifted between 30mm and 70mm (approximately 1.2" to 2.75"). These arms are engineered to restore proper suspension geometry, increasing caster by +2.5 to +3.5 degrees and offering up to 1.5 degrees of negative camber increase to maximize tire contact and stability.

Built to withstand harsh off-road environments, these UCAs feature a protective powder-coated finish and Whiteline's maintenance-free GIIRO bushing technology. The GIIRO bushings utilize a PTFE lining for a low coefficient of friction, eliminating the need for periodic lubrication while resisting oil, grease, and ozone. The arm design also provides improved clearance for the coilover strut and increased articulation at both ride height and full droop.
