ICON Vehicle Dynamics 2021-2026 Ford F-150 4WD Stage 1 Tubular Suspension System

The ICON Vehicle Dynamics Stage 1 Tubular Suspension System fits 2021–2026 Ford F-150 4WD trucks and delivers 3.5–4.5 inches of adjustable front lift over stock through a fully bolt-on, four-component kit: 2.5-inch internal-reservoir coilovers, Tubular Delta Joint PRO upper control arms, CNC-machined ductile iron front steering knuckles, and 2.0 Aluminum Series internal-reservoir rear shocks. PowerBoost hybrid models achieve 3.25–4.25 inches of front lift; Power-Stroke diesel models achieve 3–4 inches.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Tremor Geometry Without the Tremor Badge

The high-strength CNC-machined ductile iron steering knuckles replicate the suspension geometry of the F-150 Tremor, giving a standard F-150 4WD the same front-end architecture without a model swap. Combined with the 2.5-inch coilovers, this knuckle kit produces a 20% increase in front wheel travel compared to other ICON F-150 coilover kits, a meaningful gain for drivers who push their trucks on rough terrain and want the suspension to keep up rather than bind out.

Adjustable Lift, Serviceable Joints

The 2.5-inch vehicle-specific tuned coilovers are height-adjustable across the full 3.5–4.5-inch front lift range, so the truck can be dialed in for a specific tire size or ride preference without swapping springs. The internal reservoir aids heat dissipation during sustained off-road use, and corrosion-resistant CAD-plated shock bodies with 7/8-inch shafts are built for long service life.

The Tubular Delta Joint PRO upper control arms use ICON's patented Delta Joint PRO articulation joint, a rebuildable design where individual components can be removed, inspected, and replaced without replacing the entire joint. The chromoly ball and shaft are hardened to Rockwell C 55, the bearing surface is 56% larger than ICON's standard Delta Joint, and articulation spans a full 90 degrees for bind-free movement through the complete range of travel. FK rod end bearings and a high-strength alloy CNC-machined lower bar pin round out the front end.

Front-to-Rear Balance, No Drilling Required

The 2.0 Aluminum Series monotube rear shocks use vehicle-specific valving tuned to match the upgraded front damping, keeping the truck composed on- and off-road without introducing a nose-high or tail-low stance. The entire system is 100% bolt-on, with no drilling, cutting, or welding required for installation.

Specifications

Who This Is For and Isn't

This system suits 2021–2026 Ford F-150 4WD owners who want a significant lift, increased front wheel travel, and improved on- and off-road damping in a single bolt-on kit. It is a strong fit for drivers running or planning to run 34-inch tires and aftermarket wheels with lower offset.

This system does not fit the F-150 Raptor or any F-150 equipped with factory-installed electronically controlled suspension. It is not compatible with all OE wheel and tire combinations; aftermarket wheels with lower offset and less backspace are recommended. ADAS recalibration is required after installation. This system is not designed for 2WD models.

Common Questions

Will this system fit my F-150 Raptor?

The ICON Stage 1 Tubular Suspension System does not fit the F-150 Raptor. It is designed specifically for 2021–2026 Ford F-150 4WD non-Raptor models without factory-installed electronically controlled suspension.

How much front lift does this system provide on a PowerBoost hybrid or Power-Stroke diesel F-150?

On PowerBoost hybrid F-150 models, the Stage 1 Tubular system provides 3.25–4.25 inches of front lift over stock. On Power-Stroke diesel models, the front lift range is 3–4 inches over stock, compared to 3.5–4.5 inches on standard gasoline models.

Do I need to recalibrate my truck's driver assistance systems after installing this kit?

Yes. The ICON Stage 1 Tubular Suspension System requires recalibration of Advanced Driver Assistance Systems (ADAS) after installation. This step should be completed before returning the vehicle to normal use.

What wheel and tire sizes work with this lift system?

ICON recommends 34-inch by 12.50-inch tires; larger tires may fit but will require fender trimming and modifications. Recommended aftermarket wheel sizes are 17x8.5 inches with 5-inch backspace, 18x9 inches with 5.25-inch backspace, or 20x9 inches with 5.625-inch backspace. The system is not compatible with all OE wheel and tire combinations.

Is the Delta Joint PRO rebuildable, or does the whole joint need to be replaced when worn?

The Delta Joint PRO used in this system's Tubular upper control arms is fully rebuildable. The chromoly ball, shaft, and graphite-impregnated sintered metal races can each be removed, inspected, and replaced individually without purchasing a complete new joint.
