Center Shock Adjustment

[kingedwards99]

I was wondering if anyone has twisted the center shock up (front shock on the skid)? If so will this take ski pressure off the RTX? I am 230 lbs and i had 45lbs of psi in my floats but it just sits to low in the front end, i would like the front end more off the ground but when i put 55lbs it just has to much presure on the skis! by the way i am running c&a razors on my sled but 45 lbs felt good for ski pressure, but i would like more clearance over the vehicle tracks on the lakes other wise it seems a little too scarry when you hit these tracks! Any help is always greatly appreciated. p.s. i've read alot of posts but have not heard of anyone yet to move the center shock spring up!

I've messed with that adj. on my Apex RTX. You can raise the ride height on the front a little with it, like maybe an inch, but it's going to cost you in the ride dept. Not much noticable difference in steering or ride height in rear at that point. FWIW.

Do you mean the shock or spring? Tightening up the front center spring will pitch more weight onto your skis.

King....I'm guessing you notice the "scary" part when of the gas or slowing down..?

I'm certain that you will really notice the negative ride affects if you do this.

This IMO is the problem with the RTX....you cannot get the chassis balanced with the floats unless you run higher PSI. 45-50psi rides better but then makes the sled pitchie and unbalanced, it acts like a teeter-totter and added with all the weight transfer makes it a handleful in the corners.

I think the standard Nytro is a more balanced chassis.......I'm stillt rying to get a handle on this.

Adding preload to the front skid spring loads the front of the skid - not the skis. It will actually remove weight from the skis.

gormleyflyer2002, I agree with your thought - kinda. If you set up with a lot of preload on the front skid spring, you enhance the 'teeter totter' effect during weight transfer, giving the sled a pivot point to rock back and forth on when accelerating/decelerating. Good for drags, but as you mention, might be a little scary with a dodgy front end. Take away the preload though, and that pivot point seems to disappear, or at the least, not be as noticable. Might feel like it's balanced a little better like that. Just another factor to keep in mind. FWIW

Hey KindEdwards,
I have a standard Nytro and I'm also about 240lbs. I added more preload to the front skid shock (2-3mm) and I have found a major improvement in the sled. Lighter steering, less bottoming, and no issues with weight transfer. I wouldn't go crazy with the adjustment, but try it one turn at a time and see how you like it.

I personally feel that adding a little pre-load and going 1 more click on the rear shock compression clicker made a world of difference for me.

My limiters are stock, in case you were wondering.

I consider myself a semi-aggressive rider. I like rough trails and the odd 10-15 foot jump (length not height LOL).

Hope this helps.

I think this is the difference, the standard Nytro holds its nose higher compared to the RTX FOX sled which sits farther into the travel and has to carry more weight on the front track shock. I would love to see a front on type picture of both standard and RTX side by side.
i would bet that the standard models have less front to back pitch also......just add adjustable limiter block and go ride for the standard or pump the pressure on the FOX.

open to comments at this point anyway...!! LOL

So Rick, Your saying if i loosen the spring i will get less pressure to my skis?

Tightening the spring takes away ski pressure.

By tightening the spring, you create more pre-load. By creating more pressure on the front of the track, that part of the sled carries a little more of the load/weight thus reducing the weight on the skis.

Think of it as 3 pressure points (1, 2, 3) with number 1 carrying most of the weight.

---1-----2--3

If you increase the pre-load on 2, you lighten up 1.

The key is not to go too far because you will create a teetering point
