ICON Vehicle Dynamics 2021-2026 Ford F-150 Tremor 2.5-3" Lift Stage 1 Tubular Suspension System

The ICON Vehicle Dynamics Stage 1 Tubular Suspension System is a complete bolt-on lift and performance upgrade engineered specifically for the 2021-2026 Ford F-150 Tremor, delivering 2.5-3" of adjustable front lift and a 20% increase in front wheel travel over stock. The system ships as three matched assemblies: vehicle-specific 2.5" internal-reservoir coilover shocks up front, tubular upper control arms with Delta Joint PRO ball joints, and a pair of 2.0 aluminum-body internal-floating-piston rear shocks.

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.

More Wheel Travel, Better Control

The front coilovers are built to the F-150 Tremor's specific shock length, so the 20% gain in wheel travel is realized without compromising the truck's geometry or towing capacity. Internal reservoirs keep fluid temperatures in check during sustained off-road use, which preserves consistent damping when the terrain demands repeated compression cycles. Height adjustability across the 2.5-3" range lets owners dial in stance and clear larger tires without swapping springs.

Delta Joint PRO Upper Control Arms

The tubular upper control arms replace the factory units and carry ICON's patented Delta Joint PRO articulation joint. The chromoly ball and shaft are hardened to Rockwell C 55, and the bearing surface is 56% larger than ICON's standard Delta Joint, reducing deflection under load. The joint delivers a full 90 degrees of articulation (a 14% improvement in range of motion over the original Delta Joint), so suspension movement stays bind-free through the complete travel range. The joint is rebuildable: individual components can be removed, inspected, and replaced without buying an entirely new joint, which matters for long-term ownership cost on a truck used hard. The arms also increase caster over stock and help retain the factory alignment specification range, which keeps the truck tracking straight after the lift is installed.

Balanced Front-to-Rear Performance

The included 2.0 aluminum-body monotube rear shocks use vehicle-specific valving tuned to complement the front coilovers, so the truck's damping balance is consistent from front to rear rather than mismatched. The 5/8" hardened chromed steel shafts and aluminum bodies resist corrosion. These rear shocks are rated for 0-1" of rear lift over stock; they are not intended for larger rear lift applications.

Features

• Adjustable front lift: 2.5-3" of height adjustment over stock via coilover collar
• 20% front wheel travel increase: Tremor-specific coilover length maximizes travel without geometry compromise
• Delta Joint PRO: Rebuildable chromoly ball joint hardened to Rockwell C 55 with 90° articulation and 56% more bearing surface than standard Delta Joint
• Internal reservoir front coilovers: Separates gas charge from oil for consistent damping under heat
• 2.0 aluminum monotube rear shocks: Vehicle-specific valving, 5/8" hardened chromed steel shafts, compatible with 0-1" rear lift
• 100% bolt-on installation: No drilling, cutting, or welding required

Specifications

Who This Is For and Isn't

This system suits 2021-2026 Ford F-150 Tremor owners who want a bolt-on lift of 2.5-3" at the front with meaningful gains in wheel travel and damping performance for mixed on-road and off-road use, and who want to run larger aftermarket wheels and tires.

This system does not fit any F-150 trim other than the Tremor, and it is not compatible with aftermarket steering knuckles; OE steering knuckles are required. The included rear shocks are designed for 0-1" of rear lift only and are not suitable for larger rear lift applications. ADAS recalibration is required after installation. Not all OE wheel and tire combinations are compatible after the lift is installed; aftermarket wheels with lower offset or less backspace are recommended.

Common Questions

Does this system fit all F-150 model years and trims?

The ICON Stage 1 Tubular Suspension System is engineered specifically for the 2021-2026 Ford F-150 Tremor. It does not fit other F-150 trims or model years outside that range; the coilover length and control arm geometry are Tremor-specific.

Can I keep my factory steering knuckles?

Yes, and it is required. This Stage 1 system is only compatible with OE steering knuckles. Installing it alongside any aftermarket steering knuckles is not supported and is explicitly noted as incompatible in ICON's application data.

Will my factory wheels and tires still fit after installation?

Not necessarily. This suspension system is not compatible with all available OE wheel and tire combinations at the lifted height. ICON recommends aftermarket wheels with lower offset or less backspace; specific recommended sizes are 17x8.5" with 5" backspace, 18x9" with 5.25" backspace, or 20x9" with 5.625" backspace. Tires up to 34x12.50" are noted as fitting; larger tires may require fender trimming.

Does installation require cutting, welding, or drilling?

No. The ICON Stage 1 Tubular Suspension System is a 100% bolt-on system. No drilling, cutting, or welding is required during installation. ADAS recalibration is required after the lift is installed, as noted in ICON's application guidelines.

What does the Delta Joint PRO offer over a standard ball joint?

The Delta Joint PRO in these upper control arms uses a chromoly ball and shaft hardened to Rockwell C 55, with 56% more bearing surface than ICON's standard Delta Joint and a full 90 degrees of articulation. It is rebuildable: individual components can be replaced without purchasing an entirely new joint, which extends service life on trucks used regularly off-road.

Does this system affect towing capacity?

ICON states that the 20% increase in front wheel travel this Stage 1 system provides comes with no change in towing capacity compared to stock.
