Product Details

The ICON Vehicle Dynamics K53123 Stage 3 S2 Secondary Shock Upgrade System transforms the off-road capabilities of 2010-2024 Toyota 4Runner and 2010-2014 Toyota FJ Cruiser vehicles by adding high-performance secondary shocks to existing ICON coilover setups. 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:

  • 2.5-inch Aluminum Series Omega bypass shocks with remote reservoirs for superior damping performance
  • Two-tube bypass design creates multiple damping zones for optimized suspension travel
  • 28 settings of externally adjustable compression and rebound damping with no tools required
  • Utilizes factory lower control arms and maintains OE track width
  • Billet aluminum shock tower adapters and fabricated shock hoops for precise fitment
  • Integrated steel skid plates with incorporated shock mounts protect lower control arms
  • Modular design allows for staged upgrades or complete installation
  • 100% reversible installation with no permanent modifications to frame or factory components

This system provides a more affordable alternative to complex long-travel kits while delivering substantial off-road performance gains. The straightforward installation process and exceptional build quality make this an ideal upgrade for 4Runner and FJ Cruiser owners seeking serious off-road capability. The increased oil volume and damping capacity dramatically improve vehicle stability both on and off-road, while the adjustable bypass valving allows fine-tuning for specific terrain and driving conditions.

Easy explained, fast ,love it

Awesome and cheap

Easy checkout and could actually FIND the part. The only other thing I would want is a install picture. Just to make sure I was buying the right item.

cheap prices

Love the pay with Amazon feature. Unbelievably fast shipping, great pricing on product. Excellent communication through the process. I'll be back!

Simple and EZ

Easy and quick

Shopping experience was good. It's taken quite some time to find Splash Guards for my Raptor that will actually fit properly. Hopefully these are the ones (this is my third attempt).

Pricing was good and customer service quick to respond.
