From ICON
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 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.
Why this IR Shock System w/ Billet UCA
An ICON suspension system is a matched package: ICON tunes every component in the box for the 2020-2026 Chevy/GMC 2500HD/3500HD together, so lift height, spring rate and damping arrive as one calibrated setup instead of parts collected from three brands. Higher Stage numbers add components (upper control arms, rear shocks, leaf or coil springs, adjusters) on the same base system.

Questions
IR, RR, PB: what is the difference?
IR is an internal reservoir, a self-contained monotube body. RR is a remote reservoir connected by hose and PB is a piggyback reservoir bolted to the body; both add oil volume and cooling so damping stays consistent on long rough sections. IR is lighter and simpler; RR and PB resist fade.
CDCV, CDEV, CDXS: which adjuster?
CDCV is a 10-position manual compression knob. CDEV is an electronic compression valve controlled by the ICON Intelligent Control module and phone app, which reads speed and terrain and adjusts on the fly; it requires the IIC install kit. CDXS is a manual dual-circuit adjuster with 10 marked detents each for compression and rebound. Shocks without a code run ICON's fixed vehicle-specific valving.
Can these be serviced?
Yes. Every ICON shock and coilover is rebuildable and revalveable through ICON factory shock service. The shock warranty is 12 months against manufacturing defects.
What does the Stage number mean?
Stage 1 is the base system for this truck and each higher Stage adds components on top of it: upper control arms, rear shocks or springs, adjusters. The exact contents vary by platform and are listed in ICON's description above.
Do I need an alignment?
Yes. Any change to front ride height requires a four-wheel alignment after installation.
Who installs it?
ICON requires professional installation and does not cover failures caused by improper installation. Plan on a shop with a lift and an alignment rack for anything that changes ride height.
Why is this special order?
ICON builds most systems and shocks to order in Riverside, California. We confirm ICON's current lead time with you before the order is placed and you can cancel before it ships.
