Manufacturer Description

The 2001-2010 GM 2500HD / 3500HD requires significant shock damping to comply with the massive spring rate of the factory torsion bar system. ICON Vehicle Dynamics has developed a range of suspension systems with optimized vehicle specific shock damping. These systems offer excellent on and off-road drivability. While driving the construction site or trails to your favorite dirt bike location, ICON wants you to get there in comfort just like your drive to work. ICON's Stage 3 system is comprised of 2.5 VS Piggyback front & rear shocks and a tubular steel Delta Joint UCA kit. The ICON vehicle specific tuned shocks are the key to attaining optimum ride quality and getting that desired comfort with the 3/4 & 1-ton working capability. This system features upper control arms with 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 greaseable 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.
