ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks with CDEV are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. These shocks are configured specifically for each application in both length and damping tune.
For piggyback and specific remote reservoir applications, ICON'S unique use of a 6061-billet aluminum manifold a few inches below the top cap of the shock creates an internal Bump Zone that when used creates an additional 20 Percent of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity.
Like all ICON'S Shock Absorbers, V.S. 2.5 Aluminum Series shocks with CDEV are fully rebuildable and re-tunable. The ICON CDE Valve upgrade is included for those desiring an easy way to tune the ride electronically from inside the vehicle.
Features and Benefits:- Compression Damping Electronic Valve (CDEV) is an electronically controlled valve that meters the flow of oil to regulate the amount of damping force that is created by the shock when compressed. This infinitely variable valve can react in less than 40ms and has the ability to make extremely precise adjustments for varying terrain. CDEV's hydraulic circuits are also custom tailored per application to create the highest resolution and dynamic range allowable for each specific vehicle. Powered by ICON Intelligent Control and proprietary ICON mobile app, the system uses information from the onboard G-force sensor and Gyroscope to perform calculations based on algorithms and user-defined settings to predict terrain and adjust shock settings via the CDEV accordingly.
- ICON's CDE Valve technology allows for in vehicle adjustment of compression damping settings and active adjustment via the ICON Intelligent Control (IIC)
- ICON's internal InchBump Zone Inch increases damping by 20 Percent to provide more control as the shock approaches full compression
- One-piece, hard anodized, impact extruded aluminum cylinders offer excellent corrosion resistance and consistent finish
- Piggyback reservoir design improves heat dissipation to reduce shock fade during prolonged use
- Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range
- One-piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road

Dog Rope Toy
Color: Regular color
These dog rope toys are a great value, especially since several come in one pack. My dog is a black Labrador and a very aggressive chewer, so she goes through toys quickly. Each rope typically lasts her a few weeks to a month, which is impressive given how strong her bite is. She absolutely loves these and plays with them constantly.
The ropes do eventually come apart, and once the braid starts to unravel, I make sure to throw them out to prevent her from swallowing any strands. That said, these toys are very effective at keeping her busy and away from chewing household items like pillows or sofa cushions—which is a much cheaper alternative!
Overall, these are durable, affordable, and entertaining toys for strong chewers, as long as you supervise your dog during playtime.

Cane Corso Approved (Eventually Destroyed)
Color: Regular color
I bought the Forfon Tough & Strong Dog Toy for Aggressive Chewers for my Cane Corsos — and if you know Corsos, you know they don’t “chew.” They conduct demolition projects.
First impression? Solid. Thick material, strong stitching, felt durable in hand. I actually had hope. Dangerous, I know.
For about two weeks, this toy held its own. Tug sessions? Survived. Full jaw clamp tests? Passed. Backyard wrestling matches? Still standing.
Then… week three happened.
Let’s just say my dogs eventually discovered its weakness and turned it into modern art. But honestly? For aggressive chewers of this size and strength, lasting two weeks is basically a gold medal performance.
Pros:
✔ Truly tougher than most toys we’ve tried
✔ Kept my dogs entertained
✔ Withstood serious chewing pressure
Cons:
• Not indestructible (especially against Cane Corso-level jaws)
• Eventually surrendered to persistence
If you have medium to strong chewers, this will probably last a long time. If you have giant, determined jaw athletes like mine, expect a respectable lifespan — not immortality.
4 stars because nothing survives forever in this house… but this one fought bravely. 🐶💪

Not bad
Color: Regular color
These toys are strong, but all the threads will get pulled daily onto the floor, messy looking now but still lasting
