Product Details

The ICON Vehicle Dynamics Stage 2 Secondary Shock System transforms the off-road capability of 2010-2024 Toyota 4Runner and 2010-2014 Toyota FJ Cruiser vehicles by adding secondary shocks to an existing ICON coilover setup. This system effectively doubles the suspension's damping ability, allowing drivers to tackle rougher terrain and larger obstacles with enhanced confidence and control.

Key Features:

  • Vehicle-specific 2.5" aluminum series remote reservoir secondary shocks with custom tuning
  • CDC (Compression Damping Control) valve with 10 adjustable compression damping levels
  • Billet aluminum shock tower adapters for precise fitment
  • Fabricated shock hoops and integrated steel skid plates with shock mounts
  • Modular design allows for step-by-step upgrades or complete installation
  • Utilizes factory lower control arms and maintains OE track width
  • 100% reversible installation with no permanent frame modifications required
  • Skid plates can be installed independently to protect factory lower control arms

Performance Benefits:

  • Dramatically improved damping ability for off-road driving
  • Increased vehicle stability during on-road use
  • Doubled oil volume and damping capacity compared to single shock setup
  • Quick and easy compression damping adjustments via external CDC valve

This cost-effective alternative to expensive long-travel suspension kits delivers professional-grade off-road performance with straightforward installation and exceptional ICON Vehicle Dynamics build quality. The system requires no major alterations to the vehicle's frame or factory suspension components, and all components can be removed and transferred to another vehicle if desired.

Great prices. Great live customer service. Very pleased, will definitely order again.

Awesome

Great price

I was shopping for a bed cover for my truck and found that autoplicity had the lowest price when I was ready to buy. After I placed the order, I got an email notifying me that my order was shipped and got a tracking number. Seamless transaction so far. Very happy.

Easy to find product and to check out.

Am happy with price, lower than anywhere else. Product is perfect and shipping was fast. Had to call because website was down while price increases were uploaded, cost an extra $20 but still worth the savings. Would definitely buy from again.
