ICON 04-08 Ford F-150 4WD / 2009+ Ford F-150 2/4WD Rear 2.5 Series Shocks VS PB - Pair| 97720P

Product Description

If you’re driving a Ford F‑150 (2004-2023, depending on model) and you want to transform how the rear of your truck handles, rides, and responds, the ICON Vehicle Dynamics PN 97720P V.S. 2.5 Piggyback Shocks are a high-end upgrade worthy of serious consideration. These are not off-the-shelf generic shocks—they’re precision-engineered, vehicle-specific components designed to deliver noticeable improvements in driving dynamics, control, and ride quality.

Why You Should Buy

• Optimized Damping for Rear Loads: The 2.5″ diameter body paired with ICON’s piggyback reservoir design ensures thermal stability and consistent damping even when hauling or during aggressive off-road use. 

• “Bump Zone” Technology for Bottom-Out Prevention: Inside each shock is a 6061-billet-aluminum manifold that creates a “Bump Zone” which adds ~20% more damping force as the shock nears full compression. That prevents harsh bottom-outs and gives more controlled travel under load. 

• Vehicle-Specific Valving for the F-150 Rear Suspension: These shocks are dialed in for the rear of F-150 2WD/4WD (2009-23 2/4WD & 2004-08 4WD in this spec) with 0-1″ of lift over stock. That means you’re not paying for unused features—you get tailored performance. 

• Premium Build Materials for Longevity: Expect 6061 aircraft-grade aluminum CNC machined parts, 7/8″ induction-hardened chrome-plated shafts, PTFE-lined bearings, nitrogen-charged monotube design, and external piggyback reservoir that improves heat dissipation. 

• Rebuildable & Re-valveable for Long-term Use: These shocks are built to be serviceable—meaning you can overhaul them instead of replacing them when they age or when your usage demands increase. 

What You’ll Feel Driving

• Reduced rear axle hop and more composed handling: When the rear of the truck is loaded (passengers, gear, towing) or encountering undulating terrain, these shocks resist uncontrolled rebound and compression, giving a firmer yet more controlled feel.

• Improved ride comfort without sacrificing capability: The damping tune handles both the highway and off-road—giving you smoothing over imperfections while retaining firm support when you’re working the suspension.

• Confidence when hauling or towing: Because the shocks are designed for the rear and for the known lift range, you’ll experience less sag, less side-to-side sway, and more stable trailer/tow behavior.

• Better off-road composure: The piggyback reservoir and internal technology mean the shocks will manage heat and maintain performance during repeat compression cycles—so you’ll feel less fade when hitting off-camber terrain, dips, or jumps.

• Responsiveness under load changes: Whether you drop gear, cargo or upgrade tires/wheels, these shocks adapt well to changing demands without turning into mush or overly harsh.

Technical Highlights

• Model: PN 97720P — Rear application, piggyback reservoir, designed for 0-1″ lift over stock on F-150. 

• Series: V.S. (Vehicle Specific) 2.5 Aluminum Series Piggyback Reservoir. 

• Key specs: nitrogen-charged monotube, external piggyback reservoir for improved oil capacity and cooling. 

• Notable materials: 6061 CNC-machined components, 7/8″ chrome-plated shaft, PTFE lined bearings, one-piece digressive piston design. 

• Rebuildable/re-valveable: Service parts available, making future rebuilds possible. 

Fitment & Installation Notes

• Compatible vehicles: 2009-2023 Ford F-150 (2WD & 4WD) and 2004-2008 F-150 4WD (depending on spec) with 0-1″ rear lift. 

• TECH Notes: Not compatible with vehicles equipped with the Continuous Control Damping (CCD) system or vehicle models with BlueCruise, and some trims such as Tremor may be excluded. 

• Installation: Bolt-on design using OEM mounts; swap takes approximately 1 hour with common hand tools. Refer to official installation instructions for torque values and clearance checks. 

• If your vehicle has more lift or uses heavy duty towing/trailer use, you may want to review shock travel, mounting geometry and clearance for the reservoir.

Summary

If you demand more from your truck—more control, more durability, more confidence—upgrading the rear end with the ICON 97720P shocks will make a tangible difference. Whether you’re daily-driving, towing heavy loads, or exploring off-road terrain, these shocks bring technologically advanced engineering to the rear suspension of your F-150. They elevate ride comfort without sacrificing capability, tighten up body motion, and provide the kind of responsiveness you’ll feel every time you hit the throttle, corner hard, or drop into rough surfaces.

Put simply: your rear suspension won’t just follow the front—it will finally match it.
