39" Z bros front spring rate with z bros arms w/o sway bar

[Kcjepperson]

I have a 13 800 pro and have put on the Z broa front end with exit shocks, didnt like how planted the sled felt and how the front end felt like it had so much ski pressure so I took off the sway bar and moved the retainer clip down to try and compensate for removing the sway bar. I like how it feels more nimble now I just need help with the front end diving. I think I need to get stiffer springs or can it me fixed by continuing to move the retainer clip down. Which I think will only give me a higher ride height. Please help!

The ski pressure really does not have much to do with your ski shock..

More to do with your rear suspension adjustment.

Get your owners manual and read the entire section on Rear suspension adjustment....Then re-read it.

I think Polaris made this sled too light lol. I'm trying 90lb front springs with the sway bar.

I've had my frt stock springs on close to zero preload since the first ride and haven't come close to using full travel in this too-deepa-powda lol.
In my garage sidehilling it seems I would like another inch of travel out of the fronts. Just to make it stupid easy to roll.

The diving can be fixed by moving retainer clip down. Im running the 36" stance and have my clip in the 6th ring down. Buddy has his in the 7th.

Moving the clip down increases the preload on the spring and provides a more stable feeling.

Ski pressure is obtained or removed by playing with the stiffness of the rear shocks. Front ends are light on the 2013. they love to dance!

 

[Kcjepperson]

When you move your retainer clip down that far are you ending up with a really high ride height? Are you running with or without your sway bar?

 

[Kcjepperson]

What's the best way to get the retainer clip down that far. I moved it down 2 slots but having a hard time keeping the spring down to move the clip with that much pressure?

 

[mountainhorse]

Is the sled suspended off the floor?

 

[Kcjepperson]

No I am not that smart, of course it's off the floor.

2011-12 Ski shock springs for the Assault, which don't run a swaybar, are 130# as opposed to the Pro ski shock spring with swaybar being 100#. I have the Walker needles and no swaybar on my 2011 Pro, and haven't noticed much of a difference other than a little more plush ride on the whooped out trails around here

What are you guys referring to as the "retainer clip"? The shock collar? Rings? Is that the threads on the shock body counted down from the top? Sorry, I must not speak Snowest.

I don't think it's Snowest jargon. I was wondering also, but assume it's shock collar and threads they're talking about. I could be wrong and completely off track here though

ON Exit shocks there are no threads for adjustment, there are rings cut around the shock a c clip style ring fit into to hold the retainer ring in place. With this system you can run the retainer looser than the unsprung spring length without things falling apart.
Not sure if that makes sense but it would if u saw an exit shock in person.

Aha, that makes more sense. Thanks for the clarification. Now I look like a dummy, but I usually do anyway so...

So I put my retainer all the way down and it still feels soft , I will ride it tomorrow and then figure out if I need stiffer springs or just put the sway bar back on and start adjusting the rear skid shocks. Does anyone else think the limiter strap on the front is to short?

If you want a more stable feeling why not just run the sway bar? on the 36" stance there is no option for the sway bar. moving the clip down increases preload on the spring, but does not affect the ride height. Im in the 6th position simply becuse i could not get it any further down due to the stiffness of the springs i have. It took me about 2 rides to get used to the ride of the pro without a sway bar, now i love it!

What springs do you have on your shox? Might give zbroz a call.

 

[Kcjepperson]

I am not going for stable, I am trying to get the front end from diving when I am headed down a hill or if I am on a hillside or anything off camber with any powder. I have read acouple more post on here that the exit shocks work best when you do all four, did you do all four of your or just the front

 

[mountainhorse]

Phatty was right on with the swaybar comment.

The 39" front allows you to run it... Try it.

The only thing that I will differ with Phatty is in the ride height... Adding more preload to the springs will move the front up more... up to the point where the shock bottoms out on the up-stroke... there should be some sag per Ryan and Nates recommendations. To be clear though... Phatty has 10,000% more riding time on EXIT shocks than I do.

Adding 2 new rear shocks is not going to help you if those are not adjusted correctly for your setup.

Again...Your EXIT shocks...Are they PRO RMK specific shocks that you bought new???


What have you done to your rear skid.. What exactly did you try for setup in that department???

If your rear-suspension "balance" is off... you will not have good luck with your front end diving issues.

You have significantly changed your sleds suspension dynamics drastically... you need to Expect to spend some serious time getting her dialed in.

You need to do trial and error setup... take a full day to dial it in with people that wont mind the constant tweaking.


Good luck... keep us in the loop.

BTW....What did the Zolingers have to say about your Issues?

I have been researching this problem and it seems I am not the only one with the complaint, I haven't done anything with rear suspension shocks. I am going out tomorrow and having an adjustment/tweaking day. I going to mess with the rear skid shocks. From what I have read it seems like the front shock needs to be tightened quite a bit.

From your description i would put the sway bar back in. Should bolt up just fine to the 39" stance. You can also move the clips down as discussed earlier to help stiffen the preload which will also ease the "dive" feeling. doing that more than likely will solve the problem.

I dont think the rear suspension has anything to do with the dive feeling (IMO), unless you have the ski pressure cranked super high. I run a timbersled skid so my set up is a little different than most, but I like the front end dancing high most of the time, unless i am climbing a hill. The pro (especially the 13's, or those with airframes or other very stiff running boards) are super responsive to your weight distribution. meaning on a slope, splitting your weight 50/50 between right leg and left the sled will want to dive down hill every time. you must ride 60/40 or 70/30 with weight on uphill leg, even if you aren't "sidehilling". the pro wont fight you to go down hill if you do this, again it responds really well to rider input. I found that sometimes even looking down hill caused a weight shift to my downhill leg, bad habit on my part from riding other sleds, like i said earlier took me a couple of rides to correct it. try and keep your shoulders, head, and weight uphill.

if those suggestions dont work for ya, give zbroz a buzz and pick their brains. You bought their product and they are willing to help you with the fine tuning! One last question, did you buy the shox used or were they set up for a lighter rider?
