ICON 66513 4.5" Lift Front 2.0 VS IR Shock for 2005-2022 Ford F250 F350 SD 4WD

Vehicle Fitment

• 2005-2022 Ford F-250 Super Duty (All Cab/Bed Configurations, 4WD, Gas & Diesel)
• 2005-2022 Ford F-350 Super Duty (All Cab/Bed Configurations, 4WD, Gas & Diesel)

Fitment Notes

• 4WD applications only. Not compatible with 2WD Super Duty models.
• Designed for use with ICON 4.5" coil spring suspension lift systems. This shock is too long for stock height or leveled vehicles.
• Sold individually. A quantity of 2 is required per vehicle (one per side).
• Not compatible with F-350 Cab & Chassis models.
• For the remote reservoir version of this shock, see ICON part #66513R.
• For 2023-2024 Ford F-250/F-350 Super Duty 4WD applications, see ICON's updated fitment options in the current application guide.

Features

• Vehicle-specific (V.S.) valving engineered specifically for the Ford F-250/F-350 Super Duty platform with a 4.5" lift for outstanding on- and off-road ride quality
• Nitrogen-charged monotube design with internal reservoir (IR) for consistent, fade-resistant damping under sustained hard use
• One-piece linear/digressive piston design delivers a broad performance range - compliant on the street, controlled off-road
• 5/8" chrome-plated hardened steel shaft resists corrosion and surface pitting for long service life
• 6063 hard-anodized aluminum body and reservoir tubing provides superior heat dissipation, excellent corrosion resistance, and a high-tech appearance
• 6061 aluminum rod end, top cap, and internals ensure exceptional strength-to-weight ratio and long-term durability
• Polyurethane bushings, zinc-plated sleeves, and forged steel mounting stems engineered for OE factory-type fitment and noise-free operation
• Nitrile rubber top-out bumper for quiet, smooth operation at full extension
• 100% rebuildable and 100% revalveable for long-term serviceability and tuning flexibility
• Premium grade 5WT shock oil for consistent suspension damping across a wide temperature range

Product Description

The ICON 66513 is a V.S. 2.0 Aluminum Series front shock absorber engineered specifically for 2005-2022 Ford F-250 and F-350 Super Duty trucks running a 4.5" coil spring suspension lift on 4WD models. Unlike generic aftermarket shocks that use universal valving, the 66513 is vehicle-specifically tuned by ICON engineers to match the weight, geometry, and performance demands of the lifted Super Duty platform. The result is a shock that delivers a noticeably smoother, more controlled ride both on the highway and in demanding off-road terrain - without the harshness or vagueness common to lesser aftermarket options.

At the core of the 66513 is a nitrogen-charged monotube design with an internal reservoir, which separates the oil and nitrogen gas charges to prevent aeration and maintain consistent damping force even under sustained heavy use. The one-piece linear/digressive piston design provides compliant low-speed damping for daily driving comfort while ramping up control at higher shaft velocities for confident off-road performance and towing stability. The 6063 anodized aluminum body provides excellent heat dissipation, helping the shock maintain performance during extended off-road use where lesser designs would fade. Like all ICON shocks, the 66513 is 100% rebuildable and 100% revalveable, making it a long-term investment rather than a throwaway component.

Installation is straightforward, using the factory mounting locations with ICON's polyurethane bushings, zinc-plated sleeves, and forged steel mounting stems for a clean, rattle-free fit. The 66513 is designed for use with ICON's 4.5" dual-rate coil spring systems and is a component in multiple ICON Stage 1 and Stage 2 suspension systems for the 2005-2022 Super Duty. It is sold individually - two are required for a complete front axle installation. For Super Duty owners who want an elevated off-road capability and a major improvement over the factory shock without stepping up to a remote reservoir setup, the 66513 is the right choice.
