ICON Stage 3 Suspension System with Tubular UCA & Rear Links – 2010-2024 4Runner & 2010-2014 FJ Cruiser | K53063T

Upgrade your Toyota with the ICON Vehicle Dynamics Stage 3 Suspension System with Tubular Upper Control Arms and Rear Lower Links, part #K53063T, 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, tubular steel upper control arms with ICON Delta Joint, tubular steel 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 tubular upper control arms provide the additional articulation and improved alignment geometry needed to take advantage of the Extended Travel design.

Stage 3 takes the system a step further by adding ICON tubular steel rear lower links, providing increased strength, improved rear suspension geometry and adjustable rear pinion angle.

What Does Stage 3 Add Over Stage 2?

The primary upgrade from ICON K53062T Stage 2 to K53063T Stage 3 is the addition of ICON 54000T tubular steel rear lower links.

Stage 2 already provides:

• Extended Travel 2.5 Series front coilovers

• Tubular Delta Joint upper control arms

• 2" rear lift coil springs

• 2.0 Aluminum Series rear shocks

Stage 3 adds:

• ICON 54000T tubular steel rear lower links

• Increased strength compared with the factory rear lower links

• Improved rear suspension geometry

• Adjustable rear pinion angle

• Low-maintenance multi-durometer bushings

This makes Stage 3 particularly attractive for lifted vehicles where correcting rear suspension geometry and pinion angle 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

K53063T 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 tubular 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 Tubular Upper Control Arms

The K53063T Stage 3 system includes ICON 58451DJ tubular steel upper control arms.

These heavy-duty UCAs are designed specifically to complement ICON's Extended Travel front coilovers.

The tubular upper control arms provide:

• Added strength and durability

• Increased suspension articulation

• Improved alignment geometry

• Increased caster over stock

• Helps retain factory alignment specifications

• Proper wheel alignment at the lift heights provided by the system

• ICON patented Delta Joint

ICON Delta Joint

The tubular 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 of a conventional ball joint with the performance and increased angularity associated with 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

The Delta Joint provides an excellent combination of suspension articulation, durability, weather protection and quiet operation, making it particularly well suited for vehicles that see both daily driving and serious off-road use.

ICON Tubular Rear Lower Links

The defining upgrade of the K53063T Stage 3 system is the addition of ICON 54000T tubular steel rear lower links.

These links replace the factory rear lower links with substantially stronger components designed specifically for lifted and off-road Toyota applications.

Key benefits include:

• Heavy-duty tubular steel construction

• Much stronger than the OE rear lower links

• Improved rear suspension geometry

• Adjustable rear pinion angle

• Low-maintenance multi-durometer bushings

• Increased durability for off-road use

• Direct replacement for factory rear lower links

Adjustable Rear Pinion Angle

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

The ICON tubular rear lower links can be adjusted to help achieve the optimum rear pinion angle after the vehicle has been lifted.

Proper pinion-angle adjustment helps maintain appropriate driveline geometry while allowing the rear suspension to operate as intended.

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

2" Rear Lift Coil Springs

The K53063T includes ICON 52700 2-inch rear lift coil springs.

These rear springs provide approximately 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 K53063T 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 K53063T 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 K53063T 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 K53063T 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 K53063T 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.
