Through hours of in-house research and thousands of miles of real world testing~ ICON engineers have identified the limiting factors of the 1996-2004 Toyota Tacoma and 1996-2002 Toyota 4Runner OEM upper control arms and developed a kit to address these limits. Like all ICON tubular upper control arms~ these 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. These arms are engineered with built-in geometry correction for optimal alignment specifications and increased caster for confidence inspiring handling. The robust~ two piece steel taper adapter clamps from both sides of the spindle to distribute the extreme forces seen during aggressive off-road driving while CNC machining provides a precise~ OE style fit for the Delta Joint taper pin.
These upper control arms feature ICON's patent pending 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.
