ICON 58451DJ Tubular Upper Control Arm Kit with Delta Joint for Toyota 4Runner, FJ Cruiser and Lexus GX

Take the performance of your Toyota 4Runner, FJ Cruiser, or Lexus GX to new levels with the ICON Vehicle Dynamics Delta Joint tubular upper control arm kit. All ICON tubular upper control arms are constructed from CNC bent 1026 DOM steel tubing and then powder coated to a semi-gloss black finish for maximum strength and corrosion resistance. ICON upper control arms are engineered with built-in caster correction for optimal alignment specifications and confidence inspiring handling. A main benefit of ICON upper control arms is the potential for increased wheel travel when paired with our extended travel coilovers, this translates into superior performance and ride quality for your vehicle. These upper control arms feature ICON's patented Delta Joint. The Delta Joint is a heavy duty high angle ball joint that combines the durability of a ball joint with the performance characteristics of a traditional uniball. While the industry standard uniball does a great job of allowing the control arms of a vehicle to articulate with little bind, they do have an inherent weakness that leaves more to be desired when used in a daily driven application - exposure to the elements. The Delta Joint features a zinc plated housing providing the first layer of corrosion resistance, while a tough grease seal keeps potentially harmful elements out of the inner workings of the joint. Metal on metal construction and a greasable design increase the longevity of the Delta Joint while at the same time allowing for noise-free operation. What makes the Delta Joint unique is that it brings the best of both worlds to ICON upper control arms with features that make it more robust than a uniball, and at the same time capable of greater angularity than a typical ball joint. ICON tubular UCAs feature 1026 DOM tube construction, polyurethane bushings, and ICON’s greaseable Delta Joint, a hardcore high-angle ball joint that combines the durability of a ball joint with the performance of a traditional uniball.

Upgrade the front suspension performance of your Toyota 4Runner, Toyota FJ Cruiser, or Lexus GX with the ICON Vehicle Dynamics 58451DJ tubular upper control arm kit. Designed for demanding on-road and off-road use, these upper control arms provide improved suspension articulation, alignment flexibility, and dependable durability. Built-in caster correction helps achieve optimal alignment specifications, while the increased wheel travel potential works especially well with extended-travel coilovers to support improved handling, ride quality, and suspension performance.
Each ICON upper control arm is manufactured from CNC-bent 1026 DOM steel tubing and finished with a semi-gloss black powder coat for strength and corrosion resistance. CNC-machined bushing housings and sleeves, serviceable dual-stage polyurethane bushings, and precision construction help maintain controlled suspension movement and long-term serviceability. The included ICON Delta Joint is a high-angle, greaseable ball joint that combines the durability of a traditional ball joint with the articulation characteristics of a uniball. Its zinc-plated housing and durable grease seal help protect internal components from harmful elements, while the metal-on-metal design supports extended service life and quiet operation.
The ICON Delta Joint offers greater angularity than a typical ball joint while providing more protection and daily-driving durability than an exposed uniball. This kit is engineered for compatible Toyota 4Runner, Toyota FJ Cruiser, and Lexus GX applications and is an excellent choice for vehicles equipped with performance suspension upgrades. Recommended aftermarket wheels include ICON Alloys wheels measuring 17 x 8.5 inches with 4.75 inches of backspacing and zero offset. Professional installation and alignment are recommended after installation.
