The ICON Vehicle Dynamics S2 Secondary Shock System redefines the off-road capability of the 2010-2024 Toyota 4Runner and 2010-2014 Toyota FJ Cruiser by allowing for the installation of a secondary shock to an existing ICON coilover setup. The addition of secondary 2.5 Aluminum Series remote reservoir Omega bypass shocks means rougher terrain and larger off-road obstacles can be overcome with confidence as the damping ability of the vehicle's suspension is effectively doubled.

The ICON Omega Bypass shocks feature two bypass tubes, creating multiple damping zones within the shocks, and externally adjustable bypass valves that restricts oil flow through the tubes to provide 28 settings of compression and rebound adjustment, with no tools required. As opposed to overly complicated and expensive long travel kits, the ICON S2 System is an affordable upgrade that drastically increases off-road performance, is easy to install, and has a modular design that allows 4Runner FJ Cruiser Cruiser owners to upgrade in steps or all at once.

Features and Benefits:
  • The S2 Secondary Shock System utilizes the factory lower control arms and maintains OE track width while a combination of a billet aluminum shock tower adapters, fabricated shock hoops, and steel skid plates (with incorporated shock mounts) make for a straightforward install with the exceptional build quality you would expect from an ICON Vehicle Dynamics product. The system was designed to eliminate the need for any major alteration of the vehicle's frame or any other factory suspension components, and the components are 100 Percent removable in case the system is to be installed on another vehicle. The modular design of the S2 kit also allows for standalone installation of the skid plates, which provides the added benefit of protecting the factory lower control arms from potential trail damage that can be experienced while off-road.
  • Drastically improves vehicle damping ability off-road
  • Increased vehicle stability on-road
  • Utilizes factory lower control arms
  • Maintains OE track width
  • Vehicle-specific tuned secondary shocks provide increased damping and oil volume
  • Omega Series two-tube bypass allows for compression and rebound damping adjustment
  • 2.5 Aluminum Series secondary shocks feature one-piece impact extruded aluminum cylinders for excellent corrosion resistance and consistent finish
  • Shocks are fully rebuildable and revalveable
  • Mostly bolt-on design makes for straightforward install

Chicken Flavor Good, But 🔄 Rotation-Resistant✖; Best for Simpler Chewers
Size: X-Small, Color: Ring Bone, Size: X-Small, Color: Ring Bone
🐾 Hi, I’m PVD; plush sophisticate, chew critic, and active curator of rotational toy relevance. This ring bone and I never fully bonded. I sampled it maybe five times in my entire puppyhood before quietly returning it to the bin (with a single judgmental glance). Still, it does have value for the right pup. ⭐ Why I originally wanted to love it: ✔️ XS size works well for very young puppies ✔️ Chicken flavor lasts impressively long ✔️ Freezing offers temporary gum relief ✔️ Durable and safe; no odd odors or shredding 🌀 Why it’s now a respectful 3-star chew in my rotation: ✘ Never became a go-to toy (5 uses max in my life) ✘ Ring shape felt awkward, not natural or chic; hard to grip and maneuver ✘ Texture too tame vs. nubs or detailed chew surfaces ✘ When I was smaller, I much preferred the Nylabone Baby Blue Bone Chew Toy with nubs (my personal classic), and have since matured into nightly Nylabone “Nubz” edible bones This Ring Bone is Best For: • Very young puppies with minimal chew preferences • Dogs who like simple textures and circular shapes • Those just starting enrichment chew play • Freezer treat rotations (briefly) 🚫 Not ideal for: picky pups, advanced chewers, or dogs who analyze toy ergonomics (like myself). 📝 Final Re-Barks: A strong, well-made chew, but lacked the intrigue to make my permanent rotation. Works for basic chew enjoyment; not for pups with elevated taste or toy ambition. — PVD (Chew Strategist, Textural Analyst & Aspire-to-Vine Reviewer 🐶💼)

Puppy loves it!
Size: X-Large, Color: Teething Bone, Size: X-Large, Color: Teething Bone
My small puppy loves this bone! I originally purchased this for a larger dog, but my small 10 pound puppy loves it more. It’s good quality and a softer material for puppies!

A hit, but could be stronger
Size: Medium, Color: Ring Bone, Size: Medium, Color: Ring Bone
Gave this to my 11 week old pittie, and she did significant damage within 15 mins. She left a pile of chewed bits on the couch but thankfully didn't eat them. Definitely don't leave unsupervised. That said, she LOVED it and it seemed to help her teething gums so, I'm still giving it a 4/5 Puppy pics for tax

Great long lasting chew
Flavor Name: Peanut Butter, Size: Large, Flavor Name: Peanut Butter, Size: Large
We really like having these bones on hand to keep our power chewing pitties busy. The large sizes are super convenient and long lasting, and our dogs really seem to enjoy them. We have gone through several orders over the last few years, and I anticipate to keep buying this brand.
