ICON Stage 3 Suspension System with Tubular UCA – 2021-2026 Ford Bronco Sasquatch | K40013T

Upgrade your Bronco with the ICON Vehicle Dynamics Stage 3 Suspension System with Tubular Upper Control Arms, part #K40013T, a complete performance suspension package designed for improved ride quality, increased wheel travel and serious off-road capability.

Designed specifically for the 2021-2026 Ford Bronco equipped with the Sasquatch Package, the ICON Stage 3 system combines 2.5 Series Vehicle-Specific internal-reservoir front coilovers, tubular steel upper control arms with ICON Delta Joint Pro, and 2.5 Series Vehicle-Specific internal-reservoir rear coilovers with ICON-engineered triple-rate rear springs.

The system provides approximately 2-3 inches of front lift and 1.25-2.25 inches of rear lift over stock 4-door Sasquatch-equipped Broncos.

With 35" tires, ICON engineered K40013T to provide up to 11.5 inches of front suspension travel and 14 inches of rear suspension travel, making it an excellent suspension upgrade for trail driving, overlanding and aggressive off-road use.

What Does Stage 3 Add Over Stage 2?

K40013T represents a significant step up from the ICON EXP-based Stage 2 suspension systems.

Instead of reusing the factory Bronco coil springs, Stage 3 uses complete ICON Vehicle-Specific coilover assemblies front and rear with ICON-engineered springs and vehicle-specific damping.

Stage 3 provides:

• Complete front ICON coilovers

• Complete rear ICON coilovers

• ICON-engineered front springs

• Triple-rate ICON rear springs

• Increased front and rear suspension travel

• Higher available ride height

• Tubular Delta Joint Pro upper control arms

• More comprehensive spring and shock tuning

This makes K40013T a true complete suspension system rather than simply a performance shock upgrade.

Adjustable Ride Height

ICON lists the following lift range for a stock-weight 4-door Bronco with the Sasquatch Package:

Front Lift: 2-3"
Rear Lift: 1.25-2.25"

Actual lift height can vary depending on vehicle weight and configuration.

Added weight from:

• Steel bumpers

• Winches

• Skid plates

• Roof racks

• Cargo

• Recovery equipment

• Other permanently installed accessories

can reduce actual ride height.

2-Door vs. 4-Door Ride Height

ICON specifically notes:

2-door Bronco models will sit taller than 4-door models.

Customers should keep this in mind when selecting final ride height and setting coilover preload.

ICON 2.5 Series Front Coilovers

K40013T uses ICON 48600 2.5 Series Vehicle-Specific Internal Reservoir Front Coilovers.

These shocks are precision manufactured and custom valved specifically for the Ford Bronco.

Key features include:

• 2.5-inch shock bodies

• Internal reservoir design

• Vehicle-specific valving

• Adjustable ride height

• Increased front suspension travel

• Heavy-duty 7/8-inch shock shafts

• Corrosion-resistant CAD-plated shock bodies

• CNC-machined 6061 aircraft-grade aluminum components

• PTFE-lined spherical bearings

• Fully serviceable construction

The larger shock body and increased oil capacity provide improved damping control and thermal performance compared with the factory suspension.

ICON Tubular Upper Control Arms

The K40013T Stage 3 system includes ICON 48400DJ tubular steel upper control arms.

These heavy-duty UCAs are engineered to accommodate the increased lift height and suspension travel provided by the ICON coilovers.

Benefits include:

• Heavy-duty tubular steel construction

• Increased strength and durability

• Improved front suspension geometry

• Caster correction

• Improved alignment capability

• Increased suspension articulation

• ICON Delta Joint Pro

• Designed specifically to complement ICON's increased front wheel travel

ICON Delta Joint Pro

The tubular upper control arms feature ICON's patented Delta Joint Pro.

ICON specifies:

90 Degrees of Total Articulation

This increased joint movement allows the front suspension to take advantage of the additional travel available from the ICON coilovers.

Delta Joint Pro is designed to provide high-angle movement while retaining the durability and environmental protection desirable for both daily driving and off-road use.

ICON 2.5 Series Rear Coilovers

The rear of K40013T uses ICON 48610 2.5 Series Vehicle-Specific Internal Reservoir Rear Coilovers.

The rear shocks are oriented shaft-up and use ICON-engineered coil springs.

Rear features include:

• 2.5-inch shock bodies

• Internal reservoir design

• Vehicle-specific valving

• Heavy-duty 7/8-inch shock shafts

• Shaft-up orientation

• Increased rear suspension travel

• Fully serviceable construction

Triple-Rate Rear Coil Springs

A major feature of K40013T is ICON's unique triple-rate rear coil spring design.

These springs are engineered to improve both suspension performance and ride quality while allowing maximum rear suspension travel.

ICON specifically notes that the triple-rate rear coils are optimized for a near-stock-weight Bronco.

Their softer initial spring rates mean added rear vehicle weight can reduce the advertised rear lift height.

Customers carrying substantial permanent weight from:

• Rear bumpers

• Tire carriers

• Cargo systems

• Camping equipment

• Roof racks

• Recovery equipment

should account for this when evaluating final ride height.

Maximum Suspension Travel

With 35" x 12.50" tires, ICON lists:

Front Suspension Travel: Up to 11.5"
Rear Suspension Travel: Up to 14"

The increased suspension travel allows the Bronco to maintain better tire contact over uneven terrain while improving ride quality and vehicle control.

35" Tire Fitment

ICON recommends:

35" x 12.50" tires

with the appropriate wheel specifications.

This tire size allows the suspension system to achieve its published maximum wheel travel.

37" Tire Fitment

ICON states that the K40013T suspension system can safely be used with 37" and larger tires when the appropriate up-travel limiters are installed.

For 37" tires:

Front: ICON #611075 Up-Travel Limiters
Rear: ICON #611074 Up-Travel Limiters

Minor trimming may also be required depending on wheel and tire configuration.

Recommended Wheels

ICON recommends:

17" Wheels

• 17x8.5"

• 4.75" backspacing

• 0mm offset

18" Wheels

• 18x9"

• 5.00" backspacing

• 0mm offset

20" Wheels

• 20x9"

• 5.00" backspacing

• 0mm offset

Recommended Tire Size:
35" x 12.50"

OEM Wheel & Tire Compatibility

ICON confirms:

OEM Wheels & Tires Fitment: Yes

This is an important difference from the billet K40013 listing, where ICON currently specifies OEM wheel and tire fitment differently.

Bronco Everglades Fitment Note

ICON specifically states that the Bronco Everglades will have approximately 1.5-2.5 inches of front lift over stock.

This differs from the standard 2-3" front lift range published for other Sasquatch-equipped Broncos.

Steering Component Compatibility

ICON performed fitment testing using ICON and OE steering components.

Because clearance between the steering components and front coilovers is tight, ICON warns that certain aftermarket steering components may not be compatible.

Customers using aftermarket:

• Tie rods

• Steering racks

• Steering braces

• Other steering modifications

should verify clearance before installation.

ADAS Recalibration Required

ICON specifies that installation of K40013T requires recalibration of the Bronco's Advanced Driver Assistance Systems (ADAS).

Changing vehicle ride height can affect cameras, sensors and driver-assistance system calibration.

ADAS recalibration should therefore be included as part of the installation process.

Fully Serviceable ICON Shocks

The ICON shocks included with K40013T are fully serviceable.

Unlike disposable replacement shocks, these coilovers can be serviced and rebuilt as components wear, helping extend the usable life of the suspension system.

Bolt-On Installation

K40013T is designed as a 100% bolt-on suspension system.

No drilling, cutting or welding is required for installation.

A professional wheel alignment should be performed after installation and final ride-height adjustment.

ADAS recalibration is required after installation.
