Features
- Parts That Complete a Lift: Box kits gather the brackets, spacers, links and hardware an ICON lift system needs beyond its shocks and springs, packed for one platform and lift height.
- Matched to ICON Lift Systems: Each part is listed for a specific ICON lift height and platform, so the pieces fit with the rest of the ICON system on the truck.
- Drop Brackets Restore Geometry: Most box kits include track bar, sway bar, radius arm or crossmember brackets that bring the suspension back toward its factory angles after the lift.
- Laser-Cut Steel Brackets: Where a kit includes brackets, ICON typically forms them from laser-cut steel plate.
- Check Your System First: Complete ICON systems normally include their box kits; these listings are for building a system from parts or replacing a box kit.
- Contents Listed per Kit: Each listing names what is in the box, so you can match it to your lift before ordering.

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.

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

Is an alignment part of the install?

What is an ICON box kit?
It is the set of brackets, spacers and smaller parts an ICON lift system needs alongside its shocks and springs. Each box kit is built for one platform and lift height, named in its title.
Do I need a box kit if I bought a full ICON system?
Complete ICON systems normally include their box kits. These listings are for owners building a system from parts or replacing a box kit, so check the title against your lift height.
Are the brake lines needed on a smaller lift?
ICON lists each brake line kit for a lift range. Pick the one that matches your lift so the lines reach at full droop without being stretched.
