ICON 48400DJ Tubular Upper Control Arms w/ Delta Joint PRO | 2021-2026 Ford Bronco

Upgrade your 2021-2026 Ford Bronco's front suspension geometry, alignment capability, and wheel travel with the ICON Vehicle Dynamics 48400DJ Tubular Upper Control Arms with Delta Joint PRO.

Designed for Bronco owners upgrading their suspension or increasing ride height, these heavy-duty tubular upper control arms feature built-in additional caster to help correct front suspension geometry and improve alignment on lifted Broncos.

At the heart of the 48400DJ control arms is ICON's advanced Delta Joint PRO, delivering up to 90 degrees of articulation for maximum suspension movement without binding. Combined with heavy-wall 1026 DOM steel construction and serviceable dual-stage pivot bushings, these UCAs are built for demanding street, trail, and off-road use.

Delta Joint PRO – Up to 90° of Articulation

ICON's Delta Joint PRO is designed to combine exceptional durability with the articulation needed for increased suspension travel.

Compared with ICON's original Delta Joint, the Delta Joint PRO provides a 14% increase in range of motion, allowing up to 90 degrees of total articulation from one extreme to the other.

The Delta Joint PRO features:

• Up to 90° of articulation
• 14% more range of motion than the original Delta Joint
• Fully serviceable and rebuildable design
• Larger ball with 56% more bearing surface than the standard Delta Joint
• Chromoly ball and shaft
• Bearing surface hardened to Rockwell C 55
• Replaceable graphite-impregnated sintered metal races
• Improved lubrication channels
• Improved lubrication sealing
• Billet aluminum protective dust caps

The increased articulation allows the Bronco's suspension to move through its available travel while reducing the potential for upper control arm joint bind.

Corrected Geometry for Lifted Broncos

Increasing the ride height of a Ford Bronco changes its factory suspension geometry and can make achieving proper alignment more difficult.

ICON builds additional caster directly into the 48400DJ upper control arms to help restore proper geometry and improve front-end alignment on lifted Broncos.

The result is a suspension setup better suited for increased ride height, larger tires, and increased wheel travel.

Heavy-Duty 1026 DOM Steel Construction

ICON constructs the 48400DJ control arms from heavy-wall 1026 DOM steel tubing.

Each arm is CNC formed and fixture welded for precision before receiving ICON's multi-stage black powder-coated finish for long-lasting protection.

Precision-machined housings locate both the pivot bushings and Delta Joint PRO for a strong, responsive suspension assembly.

Serviceable Dual-Stage Pivot Bushings

At the frame pivots, ICON uses heavy-duty dual-stage bushings designed to be both greaseable and rebuildable.

Unlike disposable factory-style components, the serviceable design allows these control arms to be maintained for long-term use.

Factory Wheels & Tires Compatible

ICON specifies the 48400DJ upper control arms as compatible with the Bronco's factory wheels and tires.

For aftermarket wheel and tire combinations, ICON provides different recommendations depending on whether the Bronco is equipped with the Sasquatch Package.

ICON Recommended Wheel & Tire Fitment

Bronco with Sasquatch Package:

• 17x8.5 wheel — 4.75" backspacing / 0mm offset
• 18x9 wheel — 5.00" backspacing / 0mm offset
• 20x9 wheel — 5.00" backspacing / 0mm offset
• Recommended aftermarket tire size: up to 37x12.50

Bronco without Sasquatch Package:

• 17x8.5 wheel — 5.75" backspacing / +25mm offset

Frequently Asked Questions

What does the ICON 48400DJ fit?

ICON 48400DJ Tubular Upper Control Arms are designed for the 2021-2026 Ford Bronco. They do not fit the Bronco Raptor.

Are ICON upper control arms necessary when lifting a Ford Bronco?

As suspension lift increases, the Bronco's factory suspension geometry and available alignment range can become limiting factors. ICON builds additional caster into the 48400DJ upper control arms to improve front-end geometry and alignment on lifted Broncos.

ICON specifically recommends its Delta Joint PRO upper control arms when using certain ICON coilovers that provide increased wheel travel and lift height.

What is the ICON Delta Joint PRO?

Delta Joint PRO is ICON's fully serviceable and rebuildable high-articulation suspension joint. It provides up to 90 degrees of articulation to maximize suspension movement while reducing joint bind through the suspension's range of travel.

How is Delta Joint PRO different from the original ICON Delta Joint?

According to ICON, Delta Joint PRO provides approximately 14% more range of motion than the original Delta Joint. It also uses a larger ball with 56% more bearing surface, improved lubrication sealing, and a fully rebuildable design.

Can I use ICON 48400DJ upper control arms with 37-inch tires?

ICON lists 37x12.50 as the recommended aftermarket tire size for the 48400DJ when used with its specified wheel configurations. Actual tire clearance depends on suspension setup, wheel offset/backspacing, ride height, crash bars, and other vehicle modifications.

Will these upper control arms work with factory Bronco wheels and tires?

Yes. ICON specifically lists factory wheel and tire fitment as compatible with the 48400DJ.

Will ICON 48400DJ fit a Bronco Sasquatch?

Yes. ICON provides specific aftermarket wheel recommendations for Broncos equipped with the Sasquatch Package.

Does ICON 48400DJ fit the Bronco Raptor?

No. ICON specifically states that 48400DJ does not fit the Ford Bronco Raptor.

Are the ICON Delta Joint PRO control arms rebuildable?

Yes. The Delta Joint PRO is fully serviceable and rebuildable, and the heavy-duty dual-stage frame pivot bushings are also serviceable.

Important Fitment Note

Wheel and tire clearance varies based on suspension height, wheel width, offset, backspacing, tire dimensions, and other modifications. Follow ICON's recommended specifications and verify suspension and tire clearance throughout the complete range of steering and suspension travel.
