ICON Vehicle Dynamics 57720P 2.5″ VS Piggyback Rear Shock Pair – for 2007-21 Toyota Tundra (0-2″ Lift) | 57720P

When you drive a truck like the Toyota Tundra, you expect performance that matches its power and capability. The ICON Vehicle Dynamics 57720P rear shock pair delivers exactly that—a precision-engineered suspension upgrade that transforms how your truck handles, rides, and responds. Designed for 0–2″ of rear lift, these shocks bring together race-level engineering and daily-driver comfort in a single package.

Engineered Performance – Every Technical Detail Matters

• 2.5″ Diameter Aluminum Body
  The shock body is crafted from 6061-T6 aluminum through a one-piece impact extrusion process. This reduces unsprung weight, resists corrosion, and improves heat dissipation—all crucial for consistent damping performance.

• Piggyback (Remote) Reservoir Design
  The external reservoir increases oil volume and surface area, enhancing cooling and preventing fade under continuous use. You’ll notice the difference during towing, hauling, or off-road driving—when heat management truly counts.

• Vehicle-Specific Valving (VS Series)
  ICON’s engineers calibrate compression and rebound damping specifically for the Tundra platform, ensuring optimal control and comfort. It’s not a one-size-fits-all shock—it’s built precisely for your truck’s geometry and weight distribution.

• Internal Bump Zone Technology
  A proprietary manifold increases damping near full compression, acting as a hydraulic cushion that minimizes bottom-outs and harsh impacts. This provides a smoother, more controlled ride through dips, potholes, and uneven terrain.

• Premium Internal Components

  • Nitrogen-charged monotube for consistent pressure and fade resistance.

  • 7/8″ induction-hardened, chrome-plated shaft ensures durability under heavy use.

  • PTFE-lined spherical bearings and polyurethane bushings minimize friction and deflection.

• Rebuildable and Re-valveable Design
  Every ICON 57720P shock can be serviced or re-tuned to match future upgrades or evolving driving needs—making it a long-term performance investment.

What You’ll Feel Behind the Wheel

• Sharper Handling & Stability
  The precision valving and consistent damping reduce body roll and bounce, especially noticeable when cornering, braking, or carrying loads.

• Superior Ride Comfort
  Despite their performance orientation, these shocks deliver a surprisingly smooth ride on pavement, soaking up road imperfections without harshness.

• Confidence Under Load
  Whether towing a trailer or hauling heavy cargo, the 57720P keeps your rear suspension composed, limiting squat and sway for better control.

• Consistent Performance in Any Environment
  The aluminum body and reservoir design keep oil temperatures stable, ensuring predictable performance even in extreme heat or long off-road runs.

• Long-Term Durability
  Corrosion-resistant materials, precision tolerances, and rebuildability mean these shocks maintain peak performance for years, not seasons.
