ICON Vehicle Dynamics Front 3.5" Bump Stop Spacer Kit for Ford F-250, F-350 Super Duty and Excursion 4WD

The ICON Vehicle Dynamics Front 3.5" Bump Stop Spacer Kit repositions the factory front bump stops on 1999–2004 Ford F-250 and F-350 Super Duty 4WD trucks and 2000–2005 Ford Excursion 4WD vehicles running 8 inches of front lift, lowering the bump stop contact point 3.5 inches to prevent suspension over-compression during aggressive off-road use or heavy suspension cycling.

Protecting Leaf Springs, Shocks, and Shock Mounts

When a lifted Super Duty or Excursion cycles through its full suspension travel without a correctly positioned bump stop, the suspension can over-compress and transfer destructive force directly into the leaf springs, shocks, and shock mounts. The ICON bump stop spacers close that gap by relocating the factory bump stops to a position that matches the added travel created by 8 inches of front lift. The result is a defined, controlled end-of-travel limit that absorbs impact loads before they reach components that are expensive to replace.

CNC Laser-Cut Steel Construction

Each spacer is fabricated from precision CNC laser-cut steel plate and tubing, giving the kit the structural strength to handle repeated, high-load suspension cycling without deforming. A semi-gloss black powder coat finish adds corrosion resistance and a clean appearance that holds up in the mud, water, and road salt environments these trucks are built for.

Bolt-On Installation, No Permanent Modifications

The kit uses a bolt-on design that does not require cutting, welding, or permanent changes to the factory structure. Installation can be reversed, which matters for trucks that may be returned to stock or sold.

Who This Is For and Isn't

This kit is for owners of 1999–2004 Ford F-250 or F-350 Super Duty 4WD trucks and 2000–2005 Ford Excursion 4WD vehicles that are running 8 inches of front lift and need their factory bump stops repositioned to match that travel.

This kit does not fit 2WD models of the F-250, F-350, or Excursion, and it does not fit early 1999 Super Duty production vehicles. It is designed specifically for 8 inches of front lift and is not intended for vehicles with a different lift height.

Common Questions

Why do bump stop spacers matter on a lifted Super Duty?

When a Ford F-250, F-350, or Excursion is lifted 8 inches, the factory bump stops no longer contact the axle at the right point in the suspension travel. Without repositioning them, the suspension can over-compress and load the leaf springs, shocks, and shock mounts beyond their design limits. The ICON 3.5" bump stop spacers lower the contact point to restore proper end-of-travel protection.

Will this kit fit my 2WD Super Duty?

No. The ICON Front 3.5" Bump Stop Spacer Kit is designed for 4WD models of the 1999–2004 Ford F-250 and F-350 Super Duty and the 2000–2005 Ford Excursion only. Two-wheel-drive variants are not compatible.

Does my truck need exactly 8 inches of front lift for this kit to work correctly?

Yes. The ICON Front 3.5" Bump Stop Spacer Kit is engineered for applications running 8 inches of front lift over stock. Using it with a different lift height would place the bump stop contact point at the wrong position in the suspension travel and would not provide the intended protection.

Does the kit require cutting or welding?

No. The ICON Front 3.5" Bump Stop Spacer Kit uses a bolt-on design that does not require cutting, welding, or permanent modifications to the vehicle. The installation can be reversed if the truck is returned to stock or the lift is changed.
