ICON 48500DJ Billet Upper Control Arms w/ Delta Joint PRO | 2021-2026 Ford Bronco

Take your 2021-2026 Ford Bronco suspension to the next level with the ICON Vehicle Dynamics 48500DJ Billet Upper Control Arms with Delta Joint PRO. Designed for both stock-height and lifted Broncos, these premium UCAs improve front suspension geometry, increase caster and camber adjustment, provide additional suspension component clearance, and allow increased wheel travel without joint bind.

Unlike conventional tubular upper control arms, the 48500DJ is CNC machined from 6061 billet aluminum using ICON's hybrid H-beam cross-section. This design provides exceptional strength while remaining lightweight and resisting bending forces during demanding off-road use.

At the heart of each control arm is ICON's advanced Delta Joint PRO, providing up to 90 degrees of total articulation for maximum suspension movement. Combined with FK 3/4-inch rod ends and ICON's double-adjuster sleeves, the 48500DJ also allows precise on-vehicle caster and camber adjustment.

On-Vehicle Caster & Camber Adjustment

One of the biggest advantages of the ICON 48500DJ is its ability to provide quick, precise alignment adjustment without removing the upper control arms from the Bronco.

ICON's signature double-adjuster sleeves work with FK 3/4-inch rod ends at the chassis pivots to provide on-vehicle adjustment of both:

• Caster
• Camber

This additional adjustment is particularly valuable on lifted Broncos, where increased ride height changes factory suspension geometry and can make proper alignment more difficult.

CNC-Machined 6061 Billet Aluminum

ICON machines each 48500DJ upper control arm from 6061 billet aluminum.

The hybrid H-beam cross-section is engineered to remain lightweight while providing excellent resistance to bending forces compared with traditional tubular designs.

A satin anodized finish provides corrosion resistance while giving the control arms the premium appearance expected from ICON's range-topping billet suspension components.

Delta Joint PRO – Up to 90° of Articulation

ICON's Delta Joint PRO combines the durability and longevity expected from an OEM-style suspension joint with the articulation and strength required for high-performance off-road suspension.

Delta Joint PRO features include:

• Up to 90° of total articulation
• 14% greater range of motion than ICON's 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
• Integrated O-ring-sealed dust cover cap

The increased articulation allows the Bronco's suspension to move through full bump and droop while minimizing the potential for upper control arm joint bind.

FK 3/4-Inch Rod Ends

Instead of conventional rubber or polyurethane bushings at the chassis pivots, ICON uses precision FK 3/4-inch rod ends.

These premium rod ends provide strength, precise suspension movement, and responsive driving characteristics while also forming part of the control arm's adjustable caster and camber system.

Designed for Stock & Lifted Broncos

The ICON 48500DJ is designed to correct suspension geometry and allow increased travel on both stock-height and lifted Ford Broncos.

ICON specifically recommends 48500DJ or 48400DJ Delta Joint PRO upper control arms with certain ICON Bronco coilover systems because of the increased lift height and wheel travel those systems provide.

ICON also notes that factory upper control arms may not align properly beyond approximately 2.5 inches of lift with those applications.

Vehicle Fitment

Frequently Asked Questions

What does ICON 48500DJ fit?

ICON 48500DJ Billet Upper Control Arms are designed for the 2021-2026 Ford Bronco. They do not fit the Ford Bronco Raptor.

What's the difference between ICON 48500DJ and 48400DJ Bronco upper control arms?

Both use ICON's Delta Joint PRO, but their construction and chassis pivots are significantly different. The 48500DJ uses premium CNC-machined 6061 billet aluminum construction with FK rod ends and provides on-vehicle caster and camber adjustment. The 48400DJ uses heavy-wall DOM tubular steel construction with serviceable dual-stage pivot bushings and built-in additional caster.

Another important difference is wheel fitment: ICON lists factory wheel and tire compatibility for 48400DJ but not for 48500DJ.

Can I adjust caster and camber without removing the control arms?

Yes. ICON's double-adjuster sleeve system allows caster and camber adjustment on the vehicle.

What is ICON Delta Joint PRO?

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

How does Delta Joint PRO compare with the original ICON Delta Joint?

ICON states that Delta Joint PRO provides approximately 14% more range of motion and uses a larger ball with 56% more bearing surface than its standard Delta Joint.

Can I use factory Bronco wheels with ICON 48500DJ?

No. ICON specifically lists factory wheel and tire fitment as not compatible with the 48500DJ Billet Upper Control Arms.

What wheels does ICON recommend with 48500DJ?

ICON recommends 17x8.5 wheels with 4.75-inch backspacing and 0mm offset, 18x9 wheels with 5-inch backspacing and 0mm offset, or 20x9 wheels with 5-inch backspacing and 0mm offset.

Can ICON 48500DJ be used with 37-inch tires?

ICON lists 37x12.50 as the recommended aftermarket tire size. Actual clearance depends on suspension height, wheel specifications, tire dimensions, crash bars, and other modifications.

Do I need aftermarket upper control arms when lifting my Bronco?

The answer depends on lift height and suspension configuration. ICON notes that factory UCAs may not align properly beyond approximately 2.5 inches of lift with certain ICON coilover applications and specifically recommends its 48400DJ or 48500DJ Delta Joint PRO UCAs with suspension systems that provide increased wheel travel and lift.

Does ICON 48500DJ fit the Bronco Raptor?

No. ICON specifically states that 48500DJ does not fit the Ford Bronco Raptor.

Important Fitment Note

Factory wheels and tires are not compatible with ICON 48500DJ Billet Upper Control Arms. Use an appropriately specified aftermarket wheel that provides the necessary upper control arm clearance.

Wheel and tire clearance varies depending on suspension height, wheel width, offset, backspacing, tire dimensions, crash bars, and other vehicle modifications. Suspension should be cycled through its complete range of travel after installation to verify adequate clearance.
