What Does Stage 6 Add Over Stage 5?

The major upgrade from K53055T Stage 5 to K53056T Stage 6 is the additional rear suspension adjustability.

Stage 5 already includes:

• Extended Travel Remote Reservoir front coilovers

• Tubular Delta Joint upper control arms

• Tubular rear lower links

• 2" rear coil springs

• 2.5 Remote Reservoir rear shocks with Bump Zone

Stage 6 adds:

• ICON 54100T Tubular Rear Upper Links

• ICON 54200 Adjustable Rear Track Bar

These additions provide much more complete control over the geometry and position of the rear axle after the vehicle has been lifted.

Adjustable 0-3.5" Front Lift

The ICON Stage 6 front coilovers provide 0 to 3.5 inches of adjustable front lift on a stock-equipped vehicle.

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

Unlike a basic spacer lift, the ICON system replaces the factory front shock and spring assemblies with performance coilovers designed 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 lift heights are based on a stock-equipped vehicle. Added weight from bumpers, winches, skid plates and other accessories can affect actual ride height.

Extended Travel 2.5 Remote Reservoir Front Coilovers

K53056T uses ICON 58745 Extended Travel 2.5 Series Remote Reservoir Coilovers.

These coilovers provide increased front suspension droop and wheel travel, while the external reservoirs increase shock oil volume and improve heat management during prolonged suspension cycling.

Key features include:

• 2.5-inch shock body

• Extended Travel design

• External remote reservoirs

• Increased shock oil volume

• Enhanced cooling

• Improved resistance to shock fade

• Vehicle-specific shock tuning

• Adjustable 0-3.5" front lift

• Increased front droop travel

• 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 K53056T includes ICON 58451DJ tubular steel upper control arms.

These heavy-duty UCAs are designed to complement the Extended Travel front coilovers and provide the articulation required when increasing front suspension travel and ride height.

The tubular control arms provide a strong and durable alternative to ICON's billet UCA design while retaining the performance benefits of the ICON Delta Joint.

ICON Delta Joint

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

The Delta Joint combines the durability of a heavy-duty ball joint with increased angularity similar to a traditional uniball.

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

Tubular Rear Lower Links

The K53056T includes ICON 54000T tubular steel rear lower links.

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

Benefits include:

• Heavy-duty tubular steel construction

• Increased strength compared with OE rear links

• Adjustable rear pinion angle

• Improved rear suspension geometry

• Correct roll-steer geometry

• Low-maintenance multi-durometer bushings

• Improved on-road and off-road handling

Tubular Rear Upper Links

Stage 6 adds ICON 54100T tubular steel rear upper links.

These links work with the tubular rear lower links to provide additional control over rear suspension geometry.

Benefits include:

• Heavy-duty tubular steel construction

• Increased strength compared with factory upper links

• Additional rear suspension adjustment

• Works with lower links to optimize pinion angle

• Improved rear axle geometry

• Designed for demanding street and off-road use

With both upper and lower rear links upgraded, Stage 6 provides far more complete control over rear suspension geometry than lower ICON stages.

Adjustable Rear Track Bar

Stage 6 also includes the ICON 54200 Adjustable Rear Track Bar.

Lifting a solid-axle vehicle can cause the rear axle to shift laterally because of the fixed length of the factory track bar.

The adjustable ICON track bar allows the rear axle to be properly centered underneath the vehicle after the suspension height is changed.

Benefits include:

• Adjustable rear axle placement

• Helps center the axle after lifting

• Improved rear suspension geometry

• Heavy-duty construction

• Integrates with the ICON upper and lower links as a complete rear suspension system

Complete Rear Suspension Adjustment

The combination of:

• Tubular rear lower links

• Tubular rear upper links

• Adjustable rear track bar

gives the K53056T Stage 6 system much greater control over rear suspension setup.

This allows the installer to fine-tune:

• Rear pinion angle

• Rear axle placement

• Rear suspension geometry

• Rear handling characteristics

For owners looking for a complete suspension system rather than simply additional ride height, Stage 6 provides a significant advantage.

2" Rear Lift Coil Springs

The K53056T includes ICON 52700 2-inch rear lift coil springs.

These springs complement the adjustable front suspension while providing additional rear ride height and maintaining balanced front-to-rear suspension performance.

2.5 Aluminum Series Remote Reservoir Rear Shocks

Stage 6 uses ICON 57810P 2.5 Aluminum Series Remote Reservoir rear shocks.

Features include:

• 2.5-inch aluminum shock body

• External remote reservoirs

• Increased shock oil volume

• Enhanced cooling

• Improved resistance to shock fade

• Vehicle-specific tuning

• Heavy-duty 7/8-inch shock shafts

• Designed for 1-3 inches of rear lift

• ICON Bump Zone technology

• Fully serviceable construction

ICON Bump Zone Technology

The rear shocks included with K53056T feature ICON's Bump Zone technology.

Bump Zone significantly increases damping during the final 2 inches of compression travel.

As the rear suspension approaches full compression, the additional damping helps slow axle movement before the suspension reaches the end of its travel.

This helps:

• Reduce harsh bottom-out

• Improve suspension control

• Absorb larger impacts

• Maintain better vehicle composure

• Provide a more controlled ride over varying terrain

Remote Reservoir Shocks Front & Rear

Stage 6 uses 2.5 Series Remote Reservoir shocks at both the front and rear.

The increased oil volume and enhanced cooling help the shocks maintain consistent damping during prolonged suspension cycling.

This makes the system particularly well suited for:

• Aggressive trail driving

• High-speed off-road use

• Washboard roads

• Overlanding

• Extended backcountry travel

• Heavily modified vehicles

• Repeated rough-terrain driving

Important Remote Reservoir Clearance Note

ICON notes that the remote reservoir mounting brackets may interfere with some aftermarket bumper mounts or windshield washer bottles.

If your vehicle has an aftermarket bumper, relocated washer reservoir or other modifications in the reservoir mounting area, verify clearance before installation.

Expedition Coil Option for Heavier Vehicles

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

This may be useful for FJ Cruisers and 4Runners 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 K53056T 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 K53056T Stage 6 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 Stage 6 includes adjustable rear upper and lower links plus an adjustable rear track bar, the rear pinion angle and axle position should also be properly set during installation.
