Hydro Dynamics ishock

[400 MO Boy]

What does everybody think of this new front suspension package from Hydro Dynamics. It sounds pretty straight forward and complete. I just didn't know about fit and function and reliability. Also what to do about rear shock? Have the stock one rebuilt? I don't know, just gettin' everyone's opinion.

I dont know much about them since they just came out. But I have seen them and they are very well built both the control arms and shocks. I think they are more intended for the beginner type rider. But they do look very nice. And well priced. Their top of the line package is like $1800 and include upper and lower control arms, front break lines, tie-rods, front suspension with piggyback reservoirs, and instructional dvd, and tools to adjust your suspension. You can also buy all of this seperately.

[400 MO Boy]

What do you mean it is more for beginner type riders? What would you suggest for this type of improvement to a 400 EX. We use it mainly for trail riding and dunes, not racing. Thanks!

[rob-u/21]

I should of said it differently, what I meant is recreational not for racing. Here is their website http://www.atvishock.com

So are you saying someone makes these arms for H.d. .Hydro dynamics don't make there own arms but puts thier name on them ?Just wondering ..Maybe I was given the wrong info..

[HDUSA]

We design the Phantom Arms in house and have them produced elsewhere.

Hey "HDUSA" can you tell me why I should buy that frontend for my YFZ450 over other long travel brands? Thanks for your time!

The Phantom arms are not " Long travel arms", which really should be refered to as "Long shock". The Phantom arms have the shock mount in the standard position.

[MXRACER86]

but on there web site they claim there frontend is better than "long Travel"

[0VER LAND 450R]

tell me why i should buy them aswell for the 450r

[HDUSA]

We in no way are trying to discredit long travel suspension systems in anyway. Our kits are not Long Travel.

HDUSA offers affordable, convenient, complete ATV Front Suspension kits backed by a 100% Satisfaction Guarantee and Lifetime Warranty.

Is your suspension zero preload? Or ride hieght adjustable? Also do you offer a rear shock? Im intrested in this frontend for motocross but I need a low ride hieght.

[HDUSA]

This is not a ZPS System.

We are working on Rear shocks right now and will have them in the near future. Keep an eye on www.ishock.com for more information.

Feel free to e-mail us or PM us with any questions customerservice@hydrodynamicsusa.com

As far as I know there isn't any shock out there that is ride hieght adjustable. I know a lot of them claim that the preload adjuster is for making ride hieght changes but they fail to mention that you're either increasing the spring force or decreasing the spring force by making that adjustment. I'm sure I will get a lot of people disagreeing. Look at it this way. If you want to raise the quad you turn the nuts or clips down. By doing this you now have a smaller or shorter area for the spring. When a spring gets shorter it increases the spring force. Why not call it what it really is. Preload adjustment which will affect ride hieght. To answer your question they are not ride hieght adjustable but they do offer preload adjustability.

They are not going to do a ZPS shock. What I understand that they are going to come out with is a multi spring set up that will get the lower ride hieght and still utilize all the spring. In other words they are not going to use filler springs to achieve a lower ride hieght. Just to let everyone know, the Phantom arms and shocks is just the first level. It is geared more for the masses then the racers.

ZPS works the same way. They aren't filler springs. When you go in the air those filler springs aren't still compressed and DO help to absorb.

I do not agree that they help as much as you believe they do. The amount of force that the filler spring would assert is so small that you would not notice. The spring rate for the fillers is just enough to hold the wieght of the quad. Between the filler and crossover spacers is what the shock builder usses to achieve a practical ride hieght. I do agree that they do have spring force from the fully extended position but like I said there is not enough to even notice when landing from a jump or other obstacle.
