ICON K73102 Stage 2 Suspension System with Billet UCA for 2021-2026 Chevy Tahoe, Suburban, GMC Yukon, Yukon XL

The ICON K73102 is a complete Stage 2 suspension system engineered specifically for the 2021-2026 Chevrolet Tahoe, 2021-2026 Chevrolet Suburban, 2021-2026 GMC Yukon, and 2021-2026 GMC Yukon XL. The K73102 delivers 2.5 to 3.25 inches of adjustable front lift and 3 to 4 inches of rear lift using ICON's 2.5 Series internal reservoir coilover shocks, billet aluminum upper control arms with patented Delta Joint ball joints, and fabricated rear toe links all engineered and assembled in the USA. This is not a spacer kit or a budget leveling solution. The K73102 is a fully engineered performance suspension system that increases front wheel travel by up to 20 percent over stock while maintaining proper alignment geometry at the new ride height.

What the ICON K73102 System Includes

The K73102 ships as a complete, vehicle-specific kit. Every component is engineered to work together as a matched system. No mixing and matching required, no hunting for missing hardware. The kit includes four major assemblies:

• 71605 — Front 2.5 VS IR Coilover Kit (qty: 1)
• 78720DJ — Billet Upper Control Arm with Delta Joint Kit (qty: 1)
• 71610 — Rear 2.5 VS IR Coilover Kit (qty: 1)
• 71020 — Rear Toe Link Kit (qty: 1)

All mounting hardware, bushings, and installation fasteners are included. No additional components are required for standard gas or diesel-equipped SUVs without factory electronic suspension.

ICON 2.5 Series Coilover Shocks

The front and rear coilovers in the K73102 are built around ICON's 2.5 Series shock body a 2.5-inch diameter monotube shock with an internal nitrogen reservoir. The internal reservoir eliminates the need for an external reservoir line while still providing consistent damping performance under hard use. CAD-plated shock bodies resist corrosion. The 7/8-inch shaft diameter and metal construction make the shocks fully rebuildable and re-tunable for drivers who want to dial in valving for their specific use case. ICON vehicle-specific valving balances front and rear damping character to match the weight distribution and suspension geometry of these GM full-size SUV platforms.

Front coilover height adjustment is made via the threaded collar, allowing you to dial in your exact lift height within the 2.5 to 3.25-inch front range. No need to order a separate spring to change height. Adjust on the vehicle.

Billet Aluminum Upper Control Arms with Delta Joint Technology

The OEM upper control arms are a known weak point when lifting these GM SUVs. The stock arms run out of droop travel quickly at lifted heights and use ball joints that are not designed for high-angle articulation. The K73102 replaces them with ICON's billet aluminum upper control arms featuring the patented Delta Joint.

The Delta Joint is ICON's engineering answer to a problem that has plagued lifted truck builders for years — conventional ball joints fail at high angles, and traditional uniballs sacrifice sealing and longevity. The Delta Joint uses a greaseable, metal-on-metal construction with a zinc-plated housing and a grease seal that provides the high articulation angle of a uniball with the service life of a conventional ball joint. Delta Joints carry a standalone 5-year warranty. The billet arms also restore factory caster and camber adjustability, so proper alignment is achievable at the new ride height without aftermarket cams or correction bolts.

Rear Coilovers and Fabricated Toe Links

The K73102 is a true four-corner suspension solution. The rear 2.5 VS IR coilovers replace the OEM rear shocks and provide 3 to 4 inches of rear lift on Tahoe and Yukon models, or 2.5 to 3.5 inches on Suburban and Yukon XL models. Height is adjustable within that range via the threaded collar, same as the front.

At lifted ride heights, the factory rear toe links pull the rear wheels out of spec — creating toe-out conditions that cause premature tire wear and loose highway handling. The K73102 includes ICON's fabricated steel rear toe links with FK Rod End bearings, engineered to restore proper rear toe geometry at the new ride height. This is a critical component that many budget lift kits omit entirely.

Lift Range and Engine-Specific Notes

The K73102 provides different lift ranges depending on engine and body configuration. Confirm your setup before ordering.

Diesel-equipped SUVs yield less front lift due to the heavier engine weight compressing the front springs further. This is normal and expected the kit fits diesel models, the lift range is simply different. Advertised lift ranges assume a stock-equipped vehicle. Adding heavier wheels and tires will affect final ride height.

Fitment for 2021-2026 GM Full-Size SUVs

The K73102 is designed for the 2021-2026 Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, and GMC Yukon XL across all standard submodels. Confirm your factory suspension type before ordering. This kit is not compatible with vehicles equipped with Magnetic Ride Control or Adaptive Air Ride suspension from the factory (Application Note #330). For vehicles with factory electronic shocks or air suspension, see ICON's optional simulator modules listed in the application notes below.

Won't Void Your GM Factory Warranty

Under the federal Magnuson-Moss Warranty Act, a manufacturer cannot void your factory warranty simply because you installed an aftermarket suspension system. GM would need to prove that the K73102 directly caused the specific failure being claimed before any warranty denial could be upheld. Installing a high-quality, properly fitted suspension system like the K73102 does not automatically void your powertrain, structural, or electrical warranties.

Frequently Asked Questions

Does the ICON K73102 fit a 2025 or 2026 Chevy Tahoe?
Yes. The K73102 is confirmed by ICON Vehicle Dynamics to fit the 2021 through 2026 Chevrolet Tahoe across all standard submodels. Exclude any Tahoe equipped with factory Magnetic Ride Control or Adaptive Air Ride suspension.

Will the ICON K73102 fit my Tahoe or Suburban if it has Magnetic Ride Control?
No. The K73102 is not compatible with vehicles equipped with Magnetic Ride Control or Adaptive Air Ride suspension (Application Note #330). Check your window sticker or build sheet for the RPO code Z95 (Magnetic Ride Control) or Z88 (Air Ride) to confirm your factory suspension type before ordering.

Does the ICON K73102 fit diesel-powered GM SUVs?
Yes, but diesel SUVs will achieve less front lift 2 to 2.75 inches rather than the 2.5 to 3.25 inches achieved on gas-engine models. This is expected due to the heavier diesel engine. Rear lift is the same across both engine types.

What is the ICON Delta Joint and why is it better than a standard ball joint?
The Delta Joint is ICON's patented high-angle ball joint design. It provides the articulation angle of a uniball with the sealed, greaseable service life of a conventional ball joint. Standard OEM ball joints run out of travel angle quickly at lifted ride heights, causing binding and premature wear. The Delta Joint eliminates that problem while remaining serviceable with grease fittings rather than requiring replacement at every service interval. Delta Joints carry a 5-year warranty.

How much front wheel travel does the ICON K73102 add?
The K73102 increases front wheel travel by up to 20 percent over the stock suspension geometry. This translates to better body control over rough terrain, reduced bottoming out, and improved handling both on and off-road.

Does the ICON K73102 require an alignment after installation?
Yes. A full four-wheel alignment is required after installing the K73102. The billet upper control arms are adjustable for caster and camber, allowing a proper alignment to be set at the new ride height. ADAS recalibration is also required after alignment (Application Note #155).

What tires fit with the ICON K73102 on a 2021-2026 Tahoe or Yukon?
ICON recommends 33-inch tires as the standard fitment. Larger tires up to 35 inches may fit with fender trimming. OEM wheels and tires will fit without modification at the new ride height.

What warranty comes with the ICON K73102?
ICON covers the K73102 with multiple warranties by component: shocks carry a 1-year warranty; Delta Joint upper control arms carry a 5-year warranty; coil springs carry a lifetime warranty against breakage or sag. All ICON shocks are fully rebuildable they can be rebuilt and revalved rather than replaced when service is needed.

Is the ICON K73102 street legal?
The K73102 is a suspension lift system that installs on public roads. It does not modify emissions equipment. State and local regulations on suspension lift heights vary — verify your state's maximum lift height allowances. California residents should note this product carries a Prop 65 warning.
