From ICON
The ICON Vehicle Dynamics Electronic Shock Simulator Kit allows for the installation of ICON or other aftermarket coilovers and shocks on 2021-2026 Chevrolet Silverado 1500 and 2019-2026 GMC Sierra 1500 equipped with Adaptive Ride Control suspension to provide an increase in ride height and improved suspension performance. These electronic shock simulators send the return signal to the vehicles computer, making it think the OE shocks are still installed, and allow full systems functionality without error codes or warning lights on the dash. This kit is complete with a set of (4) shock simulators, enough for one complete vehicle, and easily installs into the vehicle's OE shock wiring harnesses in a simple, plug and play manner.
Why this Rear Shocks
ICON VS (Vehicle Specific) shocks are built to the exact length and valving for a 2019-2026 Chevy Silverado 1500 / GMC Sierra 1500 at the lift height listed, so they run in the middle of their travel instead of topping out or bottoming early. Digressive piston, 5WT oil and a nitrogen-charged monotube body; fully rebuildable and revalveable.

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.
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.
