What Does Stage 5 Add Over Stage 4?

The primary upgrade from ICON K40014 Stage 4 to K40015 Stage 5 is the addition of ICON billet aluminum rear lower suspension links.

Stage 4 already includes:

• 2.5 Series Remote Reservoir front coilovers

• Billet Delta Joint Pro upper control arms

• 2.5 Series Remote Reservoir rear coilovers

• Triple-rate rear springs

Stage 5 adds:

• ICON 44000 Billet Rear Lower Link Kit

This makes Stage 5 especially appealing for Broncos that see more serious trail use, where rear articulation, suspension durability and driveline geometry become increasingly important.

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 ride 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 lift height.

2-Door vs. 4-Door Ride Height

ICON specifically notes:

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

Customers should account for this when setting final coilover preload and ride height.

ICON 2.5 Remote Reservoir Front Coilovers

K40015 uses ICON 48700 2.5 Series Vehicle-Specific Remote Reservoir Front Coilovers.

Key features include:

• 2.5-inch shock bodies

• External remote reservoirs

• Increased shock oil volume

• Increased heat dissipation

• 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 remote reservoir design helps maintain more consistent damping during prolonged hard use compared with internal-reservoir shocks.

ICON Billet Upper Control Arms

The K40015 Stage 5 system includes ICON 48500DJ billet aluminum upper control arms.

These premium UCAs are designed to accommodate the increased lift height and suspension travel provided by the ICON coilovers.

Benefits include:

• Premium billet aluminum construction

• Increased strength and durability

• Improved suspension geometry

• Increased suspension articulation

• On-vehicle caster adjustment

• On-vehicle camber adjustment

• Helps achieve optimum front-end alignment

• ICON Delta Joint Pro

ICON Delta Joint Pro

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

ICON specifies:

90 Degrees of Total Articulation

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

ICON Billet Rear Lower Links

The defining Stage 5 upgrade is the ICON 44000 billet aluminum rear lower link kit.

These links replace the factory rear lower suspension links with premium billet components designed to improve strength, articulation and off-road durability.

Key benefits include:

• Billet aluminum construction

• Increased strength compared with OE rear links

• Improved rear suspension articulation

• Increased ground clearance

• Dual-durometer greaseless bushings at one end

• Heavy-duty FK rod ends at the opposite end

• On-vehicle link-length adjustment

• On-vehicle rear pinion-angle adjustment

• Replaceable rock skids

The combination of low-friction articulation and adjustable link length makes these links both a durability upgrade and a functional suspension geometry upgrade.

Adjustable Rear Pinion Angle

Lifting a vehicle changes the relationship between the rear axle and driveshaft.

ICON's billet rear lower links allow the installer to adjust link length directly on the vehicle, helping optimize the rear pinion angle for the lifted suspension.

This can improve driveline geometry while also allowing precise rear suspension setup.

Replaceable Rock Skids

The ICON billet rear links feature replaceable rock skids.

These help protect the billet links when they contact rocks and other trail obstacles.

Rather than damaging the main aluminum link body, the skid surface can take the abuse and be replaced as needed.

ICON 2.5 Remote Reservoir Rear Coilovers

The rear of K40015 uses ICON 48710 2.5 Series Vehicle-Specific Remote Reservoir Rear Coilovers.

Rear features include:

• 2.5-inch shock bodies

• External remote reservoirs

• Increased shock oil volume

• Improved heat dissipation

• 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

K40015 uses ICON's unique triple-rate rear coil spring design.

These springs are optimized for improved suspension performance and ride quality on a near-stock-weight Bronco.

The softer initial spring rates provide excellent suspension compliance, but ICON notes that additional rear 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"

This increased travel helps maintain tire contact over uneven terrain while improving traction, ride quality and vehicle control.

35" Tire Fitment

ICON recommends:

35" x 12.50" tires

with the appropriate aftermarket wheel specifications.

37" Tire Fitment

ICON states that K40015 may 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 specifies:

OEM Wheels & Tires Fitment: No

Customers should verify wheel and tire clearance before installation.

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" range published for other Sasquatch-equipped Broncos.

Rear Reservoir Clearance Note

ICON notes that the rear reservoir brackets may interfere with some aftermarket steps or rock slider mounts.

Modifications may be required depending on the design of the installed steps or rock sliders.

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 K40015 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 K40015 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

K40015 is designed as a 100% bolt-on suspension system.

No drilling, cutting or welding is required for suspension installation.

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

Because Stage 5 adds adjustable rear lower links, the rear pinion angle should also be checked and properly adjusted during installation.

ADAS recalibration is required after installation.
