Rzr xp 900 fox shocks on a 900 ranger

I have the same lift in my ranger. Interested to see how this turns out.

The RZR shocks are longer than the ranger shocks, without limit straps you will push the effective rotational arc of your turner axles, possibly causing damage at full suspension droop. The shock extended length is designed to be your suspension droop limiter, these shocks will change that. The spring rate will be less than the ranger spring rate.
And if you try to adjust them, to where you could install them, you will decrease your compression distance of the shock, possibly bottoming out, causing damage.
There may be a possibility of finding the right parameters to where it will work, but you probably will not be able to truly utilize the shock.
The suspension geometry and design are different between the two units.
Also you may have issues mounting them with the reservoirs.

But with that said, I will be curious of you feedback on this.

It should work in the back - 5" catvos has 2" longer axles so it doesn't have the same geometry as stock suspension

The axle length has nothing to do with the shock mount locations on the frame and A arms.

I looked on the catvos website and it only states that the 5" lift comes with rhino axles, it did not say anything about shocks. So this tells me that they are using the original engineered length (CL to CL) for the shock mounts.

I will say I do not have any experience with the catvos lift, so there will probably be some variables that I have overlooked. But most are manufactured along the same lines.

I'm definitely curious to see how this plays out. Can't wait to see your results!

They move shock mounting location to the top arm in the back and have a top mount relocation in the front - we'll see how it works out for me

They should be fine, install them and let the arms to full droop, if cv's bind install limiters...i'm guessing you'll be needing to spend another $100 or so for heavier springs though...

You may experience fitment issues on the passenger side because of the muffler but you can move it pretty easily too...

Didn't think about that - what's the best way to move the muffler? Anyone know what the length of stock ranger shocks is? My rangers not with me at the moment

Using the shock as a droop stop isn't the best idea anyways....i'd measure the droop that the axle binds at and install straps to keep it from getting to that point....

I may have to do that - in a stock application doesn't the shock do that?

It does, those shocks are more just spring holders though ... Pogo sticks

What's the issue with this setup?

I learned the hard way that air shocks have a very narrow range of tune-ability... If your terrain and load change much they are a poor solution...you will either have a super stiff ride or you will bottom out....in the picture they are full of oil and there is 540lbs of nitrogen in them but will still bottom in the right conditions.... they do look cool though ...

...oh, and they're for sale if you know anyone looking for a set of 2.5" King Air shocks

Who is a good source for springs?

Thanks for the help.

Little update on this - the rear stock shocks are pretty much the same length as rzr 900 shocks - looks like the only issue I will have in the back is fitting the reservoirs but I may just be able to turn them around. Not 100% sure that they will work in the front but they probably will when I pull off the catvos upper mount relocation
