ICON Stage 3 Suspension System with Billet UCA & Rear Links – 2010-2024 4Runner & 2010-2014 FJ Cruiser | K53063

Upgrade your Toyota with the ICON Vehicle Dynamics Stage 3 Suspension System, part #K53063, designed to improve suspension travel, ride quality, handling and off-road capability while adding adjustable rear suspension geometry.

Designed for the 2010-2024 Toyota 4Runner and 2010-2014 Toyota FJ Cruiser, the ICON Stage 3 system combines Extended Travel 2.5 Series front coilovers, billet aluminum upper control arms with ICON Delta Joint, billet aluminum adjustable rear lower links, 2-inch rear lift coil springs, and 2.0 Aluminum Series rear shocks.

The front coilovers provide 0-3.5 inches of adjustable front lift and increased droop travel, while ICON's billet upper control arms provide the articulation and alignment geometry needed to take advantage of the Extended Travel design.

Stage 3 takes the system a step further by adding ICON billet aluminum adjustable rear lower links, providing increased suspension articulation, reduced deflection and on-vehicle link-length and pinion-angle adjustment.

Vehicle Fitment

What Does Stage 3 Add Over Stage 2?

The primary upgrade from ICON K53062 Stage 2 to K53063 Stage 3 is the addition of ICON billet aluminum adjustable rear lower links.

Stage 2 already provides:

• Extended Travel 2.5 Series front coilovers

• Billet aluminum Delta Joint upper control arms

• 2" rear lift coil springs

• 2.0 Aluminum Series rear shocks

Stage 3 adds:

• ICON 54000 billet aluminum rear lower links

• On-vehicle rear link-length adjustment

• Rear pinion-angle adjustment

• Increased rear suspension articulation

• Reduced suspension deflection

• Stronger replacement for the factory rear lower links

This makes Stage 3 particularly attractive for lifted vehicles where correcting and fine-tuning rear suspension geometry becomes increasingly important.

Adjustable 0-3.5" Front Lift

The ICON Stage 3 front coilovers provide 0 to 3.5 inches of adjustable front lift.

This allows you to set front ride height based on your desired stance, tire size and vehicle configuration.

Unlike a basic spacer lift, ICON's coilovers replace the factory shock and spring assemblies with performance suspension components engineered to improve:

• Ride quality

• Shock damping

• Suspension travel

• Vehicle control

• Off-road performance

• Front ride height

Front Lift Range: 0-3.5"

ICON notes that published coilover heights are based on a stock-equipped vehicle. Added weight from aftermarket bumpers, winches, skid plates and other accessories can affect actual ride height.

Extended Travel 2.5 Series Front Coilovers

K53063 uses ICON 58647 Extended Travel 2.5 Series Vehicle-Specific Internal Reservoir Coilovers.

The Extended Travel design increases front droop travel when paired with the included ICON upper control arms.

Key features include:

• 2.5-inch shock body

• Extended Travel design

• Increased front droop travel

• Vehicle-specific shock tuning

• Adjustable 0-3.5" front lift

• Internal reservoir design

• Corrosion-resistant CAD-plated shock body

• Heavy-duty 7/8-inch shock shaft

• 6061 aircraft-grade aluminum CNC-machined components

• FK Rod End bearings

• Fully serviceable construction

ICON Billet Upper Control Arms

The K53063 Stage 3 system includes ICON 58551DJ billet aluminum upper control arms.

These premium UCAs are CNC machined from 6061 aircraft-grade aluminum and designed specifically to complement ICON's Extended Travel front coilovers.

Benefits include:

• CNC-machined 6061 billet aluminum construction

• Increased strength and durability

• Improved front suspension geometry

• Increased joint articulation

• On-vehicle caster and camber adjustment

• Helps retain factory alignment specifications

• Allows proper wheel alignment at increased ride height

• ICON patented Delta Joint

ICON Delta Joint

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

The Delta Joint is a heavy-duty high-angle ball joint designed to combine the durability and weather protection of a conventional ball joint with the increased angularity and performance characteristics of a traditional uniball.

Delta Joint features include:

• Heavy-duty high-angle design

• Greater angularity than a typical ball joint

• Metal-on-metal construction

• Greaseable design

• Zinc-plated housing for corrosion resistance

• Protective grease seal

• Helps keep dirt, water and contaminants away from internal components

• Designed for quiet operation

• Excellent for daily-driven and off-road vehicles

ICON Billet Rear Lower Links

The defining upgrade of the K53063 Stage 3 system is the addition of ICON 54000 billet aluminum adjustable rear lower links.

These links are CNC machined from 6061 aluminum and anodized for corrosion resistance.

They replace the factory rear lower links while providing additional strength, articulation and suspension adjustment.

Key benefits include:

• CNC-machined 6061 billet aluminum construction

• Anodized for corrosion resistance

• Increased strength compared with factory links

• PTFE-lined FK rod ends

• Polyurethane bushings

• Increased suspension articulation

• Reduced suspension deflection

• ICON Double Adjuster system

• On-vehicle link-length adjustment

• On-vehicle rear pinion-angle adjustment

Adjustable Rear Pinion Angle

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

The ICON billet rear lower links allow the installer to adjust link length and help optimize the rear pinion angle after the suspension has been lifted.

ICON's Double Adjuster system allows this adjustment to be made on the vehicle, simplifying suspension setup and fine-tuning.

This is one of the most significant functional upgrades Stage 3 provides over Stage 2.

2" Rear Lift Coil Springs

The K53063 includes ICON 52700 2-inch rear lift coil springs.

These rear springs are designed to provide 2 inches of rear lift over stock, helping produce a level front-to-rear stance while maintaining on-road comfort and improving off-road suspension performance.

2.0 Aluminum Series Rear Shocks

ICON pairs the Stage 3 system with two 56505 2.0 Aluminum Series Vehicle-Specific Internal Reservoir rear shocks.

Rear shock features include:

• 2.0-inch aluminum shock body

• Internal reservoir design

• Vehicle-specific valving

• Heavy-duty 5/8-inch shock shaft

• Designed for 1-3 inches of rear lift

• Fully serviceable construction

The rear shocks are specifically tuned to balance suspension performance from front to rear.

KDSS Compatibility

The K53063 can be used with KDSS-equipped applications, but ICON specifically states:

KDSS-equipped vehicles require ICON rear track bar #54200.

This is an important fitment requirement for customers ordering K53063 for a KDSS-equipped 4Runner or FJ Cruiser.

Adjustable Rear Track Bar Recommendation

Even on non-KDSS vehicles, ICON recommends an adjustable rear track bar to help realign the rear axle after lifting, although it is not required.

Because the factory track bar has a fixed length, increasing rear ride height can shift the solid rear axle laterally.

An adjustable track bar allows the axle to be properly repositioned beneath the vehicle.

Recommended Track Bar: ICON #54200

Wheel & Tire Recommendations

ICON confirms that OEM wheels and tires are compatible with the K53063 suspension system.

For aftermarket wheel and tire combinations, 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 Aftermarket Tire Size:
33" x 11.50"

ICON notes that larger tires may fit, but fender trimming and modifications will be required.

Actual tire clearance can vary based on wheel width, offset, backspacing, suspension height and vehicle configuration.

Expedition Coil Option for Heavier Vehicles

ICON offers an optional 700 lb/in Expedition Coil for heavier-equipped vehicles.

This can be beneficial for 4Runners and FJ Cruisers carrying substantial permanent front-end weight from accessories such as:

• Steel bumpers

• Winches

• Skid plates

• Recovery equipment

• Other permanently installed accessories

Fully Serviceable ICON Shocks

The ICON shocks included with K53063 are fully serviceable.

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

Bolt-On Installation

The ICON K53063 Stage 3 Suspension System is designed as a bolt-on suspension upgrade.

No cutting or welding is required.

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

Because the system includes adjustable rear lower links, the rear pinion angle should also be checked and properly adjusted during installation.
