Fits select 2003-2024 Toyota 4Runner, 2007-2014 FJ Cruiser, and 2003-2023 Lexus GX470/GX460.

Improve your vehicle's suspension geometry and alignment with the ICON Vehicle Dynamics Delta Joint tubular upper control arm kit. Engineered for lifted applications, these arms feature built-in caster correction to maintain proper alignment specifications and improve high-speed stability. Constructed from CNC-bent 1026 DOM steel tubing with a durable semi-gloss black powder coat, they provide the structural integrity required for rigorous off-road use while replacing worn factory components.

The centerpiece of this kit is the patented Delta Joint. This heavy-duty, high-angle ball joint combines the articulation capabilities of a traditional uniball with the sealed, greasable longevity of a standard ball joint. The zinc-plated housing and robust grease seal protect internal metal-on-metal components from road salt, mud, and debris, ensuring quiet operation and a longer service life than exposed uniballs. When paired with ICON extended travel coilovers, these arms allow for increased wheel travel for superior ride quality on and off the trail.
