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
- Remote 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
- 7/8 Inch diameter induction hardened, chrome plated shock shaft

Great book! Little known knowledge shared by a true master!
Format: Paperback
The book arrived on time and in great shape. I had just attended an in person conference by the writer of this book, Donna Eden, and left the conference feeling so much more empowered that I had to know more. Through personal health challenges that left her in constant pain and bedridden in her twenties, and doctors unsure how to help her, Donna Eden who is now in her seventies or eighties, became her own guru!! Utilizing different natural ways of healing and learning all about energy medicine she developed her own personal brand of energy medicine. She is healthy and thriving over 5 decades later. Loaded with information that will change your life and your health in this book she shares with you the knowledge and the energy medicine exercises so you can help yourself. I now own all her books!

Good Book, Very Practical
Format: Paperback
This is a very interesting read and has some great exercises in it. I really enjoyed the book. Then I went on-line and watched a couple videos of Donna Eden speaking, and I have to say she seems like a New Age looney tune, all wide eyes, soft voice and gigantic fake smiles. Itʻs a shame, really, because energy medicine is an important field and having spaced out people representing it gives it a bad name and makes it seem less valid. However, like I said, it is a good book and worth reading. Few books about the energy body actually give exercises on how to work with it yourself, so this gets over the hurdle of other books like Barbara Brennanʻs Hands of Light where if you want to learn the techniques you have to pay a lot of money and go in person to a seminar.

Book has tons of practical information and interesting stories
Format: Paperback
I have been following Mantak Chia's inner smile book and trying to understand the 5 elements theory for a long time.
Donna has not only explained how to use it in detail and but more about Chinese medicine in a way that is simple.
There is a large bibliography she draws from as well as her own papers.
She has combined kinesiology, her special talents, and her personal insights to create a powerful healing book.
I am a layman who is trying to heal herself and I have stopped my prescribed Chinese herbs after a few days since implementing her program.
It's a wholistic book written with as much information as she can impart with the feeling that she is trying to give you as much information as she can because she cares that you implement her exercises correctly.
Mantak Chia said to just try it.
Donna Eden tries to explain the functions but if you don't believe her reasoning or her whyfores, just try it.
It's faster and easier and more gratifying than any other system I have used.
She is top of the class in healing arts.
I didn't find this book until a month ago, where I was incontinent, depressed, headachy, and constantly low on energy.
Thanks to her book I will save a lot of money on diapers, herbs, pharmaceuticals.
My burning bladder noninfections are a thing of the past.
My 8 year search is over, no more empty answers.
