ICON Vehicle Dynamics 2021-2026 Ford F-150 4WD Stage 3 Tubular Suspension System with Leaf Packs

The ICON Vehicle Dynamics Stage 3 Tubular Suspension System with Leaf Packs is a complete front-and-rear upgrade for 2021–2026 Ford F-150 4WD trucks, delivering 3.5–4.5 inches of adjustable front lift and a 20% increase in front wheel travel compared to other ICON F-150 coilover kits. The system ships as a matched set of seven component groups (coilovers, knuckles, upper control arms, rear shocks, leaf packs, shackles, and hardware), so every piece is tuned to work together from the first install. PowerBoost hybrid models achieve 3.25–4.25 inches of front lift; Power-Stroke diesel models achieve 3–4 inches of front lift.

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 Stage 3 system centers on CNC machined high-strength ductile iron steering knuckles that replicate the suspension geometry of the F-150 Tremor. Pairing these knuckles with the 2.5 Series coilovers unlocks 20% more front wheel travel than ICON's own F-150 coilover kits that use stock knuckles, a meaningful gain for drivers who push the truck on uneven terrain. Because the knuckles restore factory-style geometry at the new lift height, the system retains the factory alignment specification range rather than forcing a compromise.

Front Coilovers Built for Heat and Adjustability

The 2.5 Series front coilovers feature remote reservoirs that separate the oil volume from the shock body, reducing heat buildup during sustained off-road use and maintaining consistent damping when the truck is working hard. Coilover height is adjustable across the full 3.5–4.5 inch front lift range, letting the owner dial in ride height for a specific wheel-and-tire combination or load condition. Shock bodies are CAD plated for corrosion resistance, shafts measure 7/8 inch, and FK rod end bearings are used for longevity and minimal deflection.

Delta Joint PRO Upper Control Arms

The tubular upper control arms use ICON's patented Delta Joint PRO articulation joint. The Delta Joint PRO combines factory-style ball joint durability with motorsports-level strength: a chromoly ball and shaft hardened to Rockwell C 55, graphite-impregnated sintered metal races, and a full 90 degrees of articulation (14% more range of motion than ICON's standard Delta Joint). Every component of the Delta Joint PRO is individually rebuildable and replaceable without purchasing a complete new joint. The tubular arm design also increases caster over stock, supporting the lift height the system provides.

Rear System: Shocks, Leaf Packs, and Shackles

ICON 2.5 Aluminum Series piggyback reservoir rear shocks use vehicle-specific valving to balance rear damping with the upgraded front. Multi-rate leaf packs replace the factory leaf springs and rear blocks, eliminating axle wrap and giving the owner three configurable spring-rate options. With the included billet aluminum 1-inch lowering shackles, Option 1 (as shipped) raises rear ride height 1.5 inches over stock unloaded; Option 2 adds 20% spring rate and 2.75 inches of rear lift unloaded (1.5 inches with a 400 lb constant load); Option 3 adds 40% spring rate and 3.5 inches of rear lift unloaded (1.0 inch with an 850 lb constant load). The shackles use OE Ford bushings and require no maintenance.

Who This Is For and Isn't

This system suits 2021–2026 Ford F-150 4WD owners who want a significant lift, more front wheel travel, and tunable rear spring rates for mixed on-road and off-road use. The bolt-on design requires no cutting or welding.

This system does not fit F-150 Raptor models, 2WD F-150 models, or any F-150 equipped with factory electronically controlled suspension. ADAS recalibration is required after installation. Trucks with Dynamic Bending Headlamps require an additional sensor mount kit (ICON part 611081), sold separately. Onboard Scales accuracy may be reduced when the rear spring rate is lowered. Not all OE wheel and tire combinations are compatible; aftermarket wheels with lower offset are recommended.

Common Questions

Does this system fit the F-150 Raptor?

The ICON Stage 3 Tubular Suspension System for 2021–2026 Ford F-150 4WD does not fit the F-150 Raptor. It is also incompatible with 2WD F-150 models and any F-150 equipped with factory electronically controlled suspension.

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

On a standard 2021–2026 F-150 4WD, the front coilovers are height-adjustable for 3.5–4.5 inches of lift over stock. PowerBoost hybrid-equipped models achieve 3.25–4.25 inches of front lift; Power-Stroke diesel-equipped models achieve 3–4 inches of front lift.

What rear lift heights are possible, and how are they set?

The multi-rate leaf packs ship in Option 1 configuration, providing 1.5 inches of rear lift over stock unloaded. Reconfiguring the leaf pack to Option 2 yields 2.75 inches of rear lift unloaded; Option 3 yields 3.5 inches unloaded. Each option also changes the spring rate, affecting how the rear handles constant loads.

Is any cutting or welding required to install this system?

The ICON Stage 3 Tubular Suspension System is a 100% bolt-on system with no cutting or welding required. However, ADAS recalibration is required after installation, and trucks with Dynamic Bending Headlamps require an additional sensor mount kit sold separately.

What wheel and tire sizes work with this system?

Aftermarket wheels with lower offset and less backspace than most OE combinations are recommended. Compatible ICON Alloys sizes include 17x8.5 inches with 5-inch backspace and 6mm offset, 18x9 inches with 5.25-inch backspace and 6mm offset, and 20x9 inches with 5.625-inch backspace and 16mm offset. The recommended maximum tire size is 34x12.50 inches; larger tires may require fender trimming.
