ICON Vehicle Dynamics 78550DJ Delta Joint Tubular Upper Control Arm Kit 01-10 GM 2500HD / 3500

When lifting or leveling out your Chevy HD, its imperative to upgrade the upper control arms to not only ensure you are properly aligned, but also retain the full range of motion of the suspension. Overall, aftermarket UCA's place your wheel back into a stock-like location once the effects of triangulation come into play after raising the front end, as well as allow the suspension to actually articulate more than the stock control arms would allow. In the past, the options for upgrades were abundant, but each had their own flaws, that is until the release of the Delta Joint by ICON Vehicle Dynamics.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 ICON's 2.5 series coilovers, which translates into superior performance and overall ride quality. 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.
