Features
- Built in Stages: Each vehicle's systems climb from an entry stage upward, so the suspension can match a daily driver, a tow rig or a dedicated trail truck. The stage number tells you where a kit sits.
- Engineered Per Platform: ICON develops each system around one vehicle's geometry, choosing shock lengths, valving and spring rates for that platform instead of adapting a universal kit.
- Serviceable ICON Shocks: The ICON shocks in every stage are fully rebuildable and re-tunable, so worn seals or a change in how the truck is used means a rebuild or revalve, not new shocks.
- Adjustable Valving Options: Higher stages on many vehicles add CDCV valves with 10 compression settings, CDXS valves with separate low-speed and high-speed adjustment, or CDEV valves that ICON Intelligent Control adjusts on the move.
- Upper Control Arm Choices: Where a stage adds upper control arms, choose billet aluminum arms with caster and camber adjustment on the vehicle, or tubular steel arms with extra caster built in. Both correct front-end geometry at the lifted height.
- Lift Quoted on Stock Vehicles: Every lift range is quoted for a stock-equipped vehicle. Bumpers, winches and other added weight change where the height settles, so allow for them when choosing a kit.
Description & Fitment
Here is ICON's stage suspension system sized for the 2007-2016 Chevrolet Silverado 1500 and 2007-2016 GMC Sierra 1500. Going by ICON's component sheets, the entry Stage 3 (K73003) covers front VS 2.5 coilovers, upper control arms and rear VS 2.5 shocks. 3 versions are listed here: Stages 3 through 5 and 1-3" or 1-2.5" of lift, by version. ICON's sheet calls for the vehicle to be aligned once the parts are in.

About ICON Vehicle Dynamics
ICON Vehicle Dynamics designs and builds performance suspension for trucks and SUVs at its shop in Riverside, California. Engineering is led by Dylan Evans, its head engineer and a SCORE champion driver, and ICON tests its parts on the street, on the trail and under race conditions.
ICON's engineers begin with the result they want from a vehicle, then study the forces acting on it in motion, which is where the name Vehicle Dynamics comes from. Fabrication stays in ICON's own shop, from laser cutting and metal forming to CNC machining, welding and final assembly. ICON calls its suspension systems and shock absorbers the top choice for popular trucks and SUVs.
Authorized ICON Vehicle Dynamics dealer. Prestige Truck is an authorized ICON Vehicle Dynamics dealer, so every ICON part we sell is new and genuine. ICON's warranty is for the original retail buyer, on the vehicle the part was first installed on. Keep your Prestige Truck order receipt: we use it when we take a claim to ICON for you.
Frequently Asked Questions
Will this fit my 2007-2016 Chevrolet Silverado 1500?
It fits when your vehicle matches one of these rows: 2007-2016 Chevrolet Silverado 1500 (1-3" lift); 2007-2016 Chevrolet Silverado 1500 (1-2.5" lift); 2007-2016 GMC Sierra 1500 (1-3" lift); 2007-2016 GMC Sierra 1500 (1-2.5" lift). If you are unsure about your trim or drivetrain, send us your VIN and we will check it against ICON's application list before you order.
Is an alignment part of the install?
Yes. ICON's install sheet for K73003 calls for the vehicle to be aligned once the system is in. The sheet is linked in the Installation section below.
Which stage should I choose?
Start from how the vehicle is used. Entry stages improve ride quality and set the stance for daily driving, towing and light trail work, while higher stages add parts such as upper control arms, adjustable valving and rear links for harder off-road driving. The In the Box column of the Versions table shows what each stage adds.
CDCV, CDXS or CDEV: what is the difference?
CDCV is an external knob with 10 compression settings from soft to firm. CDXS adjusts low-speed and high-speed compression separately. CDEV is an electronic valve that ICON Intelligent Control adjusts from onboard sensors, through the ICON app.
Will I need an alignment after installing?
Yes, whenever the system changes the front suspension. ICON calls for a professional alignment, and many late-model vehicles also need their driver-assist cameras and sensors recalibrated.
How much does the lift change with a bumper or winch?
ICON quotes every lift range for a stock-equipped vehicle. A steel bumper, winch or other weight up front settles the vehicle lower in that range, so plan for it when you pick the lift option.
Installation
- Jack
- Jack Stands
- Torque Wrench
- 18mm Socket / Wrench
- 21mm Socket / Wrench
Here's the short version. Follow ICON's install sheet (below) for your vehicle's exact steps and torque values.
- Using a properly rated jack, raise the front of the vehicle and support the frame rails with jack stands. Ensure the jack stands are secure and set properly before lowering the jack. NEVER WORK UNDER AN UNSUPPORTED VEHICLE.
- Support the spindle so that it does not overextend the CV joints when detached.
- With the upper control arm disconnected from the spindle, loosen the upper control arm from its mounts on the frame using a 21mm wrench/socket. Remove OEM upper control arm.
- Each arm is clearly labeled which side and it should be installed on.
- Pivot the Delta Joint stem so that it is inline with the taper bore in the spindle. The new Delta Joint will be very stiff the first time you move it.
- Have the vehicle professionally aligned.

Warranty, shipping & returns
-
Warranty
ICON shocks and coilovers in this system carry ICON's 1-year shock warranty against manufacturer's defects, and ICON's other suspension components carry its Limited Lifetime Warranty.- Coverage belongs to the original retail buyer who owns the vehicle the parts were first installed on.
- A shock that fails in its first year goes to ICON for inspection and service. If ICON finds the cause was neglect, poor installation or anything other than normal wear and tear, the owner pays for labor, parts and shipping.
- ICON parts must go on as the complete kit shown in ICON's application guide. Swapping out or leaving off a required part voids the warranty.
- Upper control arms with ICON's Delta Joint carry 5 years of coverage from the purchase date, but only when ICON's warranty registration is completed within 30 days of purchase; contact us and we will help you register. The Delta Joint PRO carries 1 year. Neither is transferable to a later owner.
- ICON repairs or replaces a defective part, at its discretion. Removal, reinstallation, freight and incidental or consequential costs are not covered, and parts that wear in normal use are not treated as defective.
- Not covered: finish (including finish marks from shipping), alterations or modifications, installation that departs from ICON's instructions, racing use, police, taxi, government or commercial vehicles, and sales outside the United States and Canada.
- To claim, contact us first with your order number and a short description of the problem. We open the claim with ICON for you, and your Prestige Truck receipt is the proof of purchase ICON asks for.
