ICON 2023-2026 Ford F-250/F-350 Super Duty 4WD 4.5-Inch Lift Front Box Kit

The ICON Vehicle Dynamics Front Box Kit (SKU 64051) supplies the sway bar drop brackets, extended brake lines, and bump stop spacers needed to complete a 4.5-inch lift installation on 2023–2026 Ford F-250 and F-350 Super Duty trucks equipped with 4WD. This kit is a required hardware companion to ICON 4.5-inch front lift systems for these trucks, not a standalone lift kit.

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.

Bind-Free Sway Bar Motion

The sway bar drop brackets are fabricated from CNC laser-cut steel plate and powder-coated for corrosion resistance. Dropping the sway bar mount to match the lifted axle position keeps the sway bar links operating through their designed range of motion across the full suspension travel, preventing the binding that causes premature wear on links and end bushings.

Brake Line Protection Without Hard-Line Modification

The kit includes an extended-length stainless steel braided brake line set sized for the 4.5-inch lift height. Running longer lines eliminates the need to bend or re-flare the factory hard lines, avoiding the stress risers and potential leak points that modification introduces. Stainless braiding resists abrasion from trail debris and corrosion in wet or salted conditions.

Properly Rated Bump Stop Spacers

CNC-machined 6061 aluminum bump stop spacers reposition the bump stop contact point to match the new suspension geometry at 4.5 inches of lift. Correctly limiting upward wheel travel protects the shock, CV axle, and brake lines from over-extension under hard off-road impacts. Both the correct height and sufficient material strength are required for this function to work as intended.

Who This Is For and Isn't

This kit is for owners of 2023–2026 Ford F-250 or F-350 Super Duty trucks with 4WD who are installing an ICON 4.5-inch front lift system and need the sway bar, brake line, and bump stop hardware to complete that installation correctly.

This kit does not fit 2WD Super Duty models. It is not a complete lift kit and does not include shocks, coilovers, or springs. It is not compatible with lift heights other than 4.5 inches.

Common Questions

Is this kit a complete lift kit on its own?

No. The ICON Front Box Kit (SKU 64051) is a required hardware component of an ICON 4.5-inch front lift system for 2023–2026 Ford F-250/F-350 Super Duty 4WD trucks. It does not include shocks, coilovers, or springs and must be used alongside the corresponding ICON lift components.

Does this kit fit 2WD Super Duty trucks?

No. The ICON Front Box Kit SKU 64051 is specified for 4WD models of the 2023–2026 Ford F-250 and F-350 Super Duty only. It is not compatible with 2WD drivetrain configurations.

Why are extended brake lines included instead of drop brackets?

Extended-length stainless steel braided brake lines sized for the 4.5-inch lift eliminate the need to bend or re-flare factory hard lines. The longer lines accommodate the increased suspension travel without modifying the OE hard line routing, preserving the integrity of the factory hard line connections.

What is the bump stop spacer made from, and why does the material matter?

The bump stop spacers in this kit are CNC-machined from 6061 aluminum. At the 4.5-inch lift height, correctly positioned spacers limit upward wheel travel to protect the shock, CV axle, and brake lines from over-extension under hard impacts. Both the correct height and sufficient material strength are required for the spacers to perform this function reliably.
