ICON 4.5" Stage 1 Suspension System 2023 Ford F-250 / F-350 SuperDuty

For those who want a complete suspension upgrade, the ICON Complete Suspension Systems for Ford Super Duty trucks are the perfect option. Starting from Stage 1, these systems feature ICON Dual Stage Front Coil Springs and 2.0 Series Shock Absorbers (or 2.5VS Coilovers on Coilover Conversion Systems). The rear shocks are ICON 2.0 Series Internal Reservoir Shocks. This basic kit provides a 4.5" front-end lift while improving ride and handling over the stock suspension.

FRONT 4.5" BOX KIT

The ICON Ford F-250/F-350 Super Duty 4WD Front Box Kit is an essential component of ICON 4.5” lift suspension systems. Front sway bar drop brackets fabricated from CNC laser cut steel plate ensure bind free motion of the sway bar links through the entire range of suspension travel and are powder coated for corrosion resistance. Extended length stainless steel brake line kit prevents brake line damage and eliminates the bending of OE hard lines typically required for brake line drop brackets. Bump travel is properly limited with robust CNC machined 6061 aluminum bump stop spacers that are designed for the stresses of aggressive off-road driving.

FEATURES & BENEFITS:

• Drops sway bar to prevent bind in sway bar links
• Extended length stainless steel braded brake lines
• Heavy duty bump stop spacers proper limit suspension travel
• CNC machined, laser cut, and brake formed components

4.5" DIESEL DUAL RATE COIL SPRING KIT

The ICON Vehicle Dynamics Ford F-250 and F-350 Super Duty 4.5" coil springs are designed for drivers demanding the ultimate in performance and ride quality, while allowing for increased wheel travel (when used with ICON shocks) and the fitment of larger tires. The ICON Ford Super Duty coil springs provide 4.5" of lift height and feature a dual rate design optimized for use with trucks equipped with diesel engines. The dual rate design allows for a softer initial rate for superb on-road comfort and a firmer secondary rate that increases during compression for excellent bottoming resistance and off-road performance.

FEATURES & BENEFITS:

• 4.5" lift height over stock
• Dual rate coil springs improve on and off-road ride quality over stock
• Vehicle specific spring rates optimized for use with trucks equipped with diesel engines
• Dual-stage, semi-gloss powder coat offers excellent corrosion resistance
• 100% bolt-on system makes for an easy install

TRACK BAR BUMP STEER BRACKET KIT

This bracket features a 2-position cam that will optimize the track bar geometry for both 2.5” and 4.5” lifts. This component has been designed to work with both a factory track bar as well as an ICON Vehicle Dynamics adjustable unit, and will allow for the axle to be properly centered under the frame with either. Benefits of this improved geometry and axle alignment include reduced road feedback throughout the steering system and improved on and off-road manners thanks to the elimination of bump steer.

FEATURES & BENEFITS:

• Bolt-on design utilizes factory frame holes for simple installation
• Corrects bump steer geometry
• 2-position cam optimized for 2.5” & 4.5” lifts
• Centers front axle under frame with factory track bar
• Reduces road feedback through steering
• Durable satin black powder coat finish

RADIUS ARM DROP KIT

The ICON Radius Arm Drop Kit for the Ford F-250/F-350 Super Duty 4WD allows the use of the stock or aftermarket radius arms with ICON 4.5” lift suspension systems. This kit consists of fabricated radius arm drop brackets, CNC laser cut and brake-formed from steel plate and is engineered to withstand the stresses of aggressive off-road driving. The drop brackets look as great as they perform with a durable semi-gloss black powder coat finish.

FEATURES & BENEFITS:

• Drops radius arms for use with ICON 4.5” lift suspension systems
  
• Reduces radius arm angle and aids in caster correction
• Fits stock or aftermarket radius arms
• Brackets are fabricated from CNC laser cut and brake-formed steel plate
• Engineered to withstand the stresses of aggressive off-road use
• Corrosion resistant semi-gloss black powder coat finish
• 100% Bolt-on - no cutting or welding necessary for install

5" BLOCK KIT

The ICON Vehicle Dynamics Ford F-250/F-350 Super Duty 5” Rear Block Kit features a square, non-tapered block design to provide easy rear lift to a Ford Super Duty pickup. These heavy-duty blocks are fabricated from CNC laser cut and brake-formed steel plate and heavy duty .250” wall square tubing to endure the stresses of heavy towing/hauling duty as well as aggressive off-road use. Their reinforced bump stop tang provides proper bump stop engagement and limits compression travel to prevent damage to the rear shocks and shock mounts at full bottom out.

FEATURES & BENEFITS:

• Vehicle specific, square block design with 5” overall height
• Fabricated from CNC laser cut and brake-formed steel plate and heavy-duty .250” wall square tubing
• Heavy-duty bump stop tang provides proper bump stop engagement
• Semi-gloss black powder coat finish for corrosion resistance

REAR 15" U-BOLT KIT

The ICON Vehicle Dynamics Ford F-250/F-350 Super Duty 15” U-bolt kit consists of high-quality grade 8 U-bolts to ensure that the leaf springs stay properly secured to the rear axle. Featuring a black E-coat finish for corrosion resistance and a length of 15” these U-bolts will work with a variety of leaf spring and rear block options. All mounting nuts and washers are also included to make sure installation is quick and easy.

FEATURES & BENEFITS:

• High strength, grade 8 steel hardware
• 15" length
• Black E-coat finish for corrosion resistance
• Kit includes U-Bolts, nuts, and washers

LEAF SPRING EXPANSION PACK (OPTIONAL)

ICON's 2" Rear Leaf Expansion Pack provides increased suspension lift and better ride quality for lifted Ford F-250/F-350 Super Duty pickup trucks. The Expansion Pack is designed to replace and improve the center leaves of the stock leaf spring pack while retaining the factory main leaf. This makes the Expansion Pack both cost-effective and an easier installation as it doesn't require complete removal of the leaf spring main leaf from the spring hanger and shackle. The additional leaves included in the pack are designed to optimize ride quality and reduce axle wrap compared to lift blocks. The design also shifts the overload transition point to improve small bump compliance.

FEATURES & BENEFITS:

• Provides 2” of rear lift when installed with OE rear blocks
• Reduces axle wrap compared to lift blocks
• Offers improved ride quality compared to OE leaf springs
• Moves overload transition point further away for better small bump compliance
• More cost effective than a full leaf pack
• Retains factory main leaf for easier installation than a full leaf pack
