This is a discussion on X3 Suspension Set Up, "The Suspension Guy" within the The Suspension Guy forums, part of the Can-am Maverick Supporting Vendors category; Originally Posted by PropDr All other factors equal, a coil spring is a length of spring wire that is being twisted.

As far as lenght goes, the longer the spring, means that spring can achieve higher spring rates when it is fully compressed to block height.
Example, for an Eibach quality spring.
if we have a 10 inch long 3.0, 400 rate spring. This spring can be compressed to 4 inches, to get it to 4 inches takes 2400 lbs. that means you have 6 inches of progressive rate from 0 to 2400 lbs
that same 400 rate spring in a 14 inch length can be compressed down to 5 1/2 inches. To reach this takes 3300 lbs end rate over 8 1/2 inches. This 400lbs progressive rate is the same but reaches a higher end rate with a longer spring.
If we add another spring, and crossover rings, we get a dual rate system that will further add all kinds of spring rate Progressiveness with room to tweek it it to taste.
The dual rate set up lets us have an area of shock movement where the we can start with a lower spring rate that progresses slower. Then give us a later area of movement that the spring rate progresses faster.
The softer as it gets longer doesn’t really apply to these types of springs used on these cars.
Sorry if there is some confusion on how these springs work.

Does anyone have a how to video or step by step directions on how to set up the suspension or more aggressive higher speed settings? I like to haul ass and jump so id like to set it up without the nose dive and bottoming out
Little for more food for all you info hounds
comparison stuff as far as Suspension goes for the x3 and new Polaris rzr S Dynamix
should you sell your x3 for a new rzr because its light years better?? No, not really.
But the long travel rzr is a very good improvement for that car.
The shocks on the Rzr S ( for the ones that don’t know) are a RC2 class of shock. So its a real 2.5 front and rear. And yes, these are aluminum bodies with a steel sleeve so there is no inside wear issues and weight has been reduced compared to the steel shock body versions. And yes, these new shocks will run cooler with less fading characteristics.
And, Fox owns the shocks only!! Polaris owns and designed that electronic compression adjuster and the Dynamix computer!
The standard travel XPT has the same Fox bipass type shocks as our X3 long travel cars.
As we know, the Xpt and x3 version shocks are boat anchors as far as weight is concerned! But on the 2018 popo, Fox redesigned the XPT boat anchor bipass steel shocks to aluminum outside and including the inside bipass tube! Good move! I think its safe to say that future X3 bipass foxes may also get a new weight trimmed down version ??? We shall see?
The new aluminum rc2 type shocks on the rzr S are light weight as compared to the past Fox shock steel models. Part of the popularity of the Walker evans velocity aluminum shocks for the X3 long travel is the 70 lbs it takes off the car as compared to the stock Fox set up. Also, within the heat shedding aluminum comes less fading issues as compared to the steel bipass Foxes.
Did anyone notice how many walker evans velocity shocks were on the top 12 UTV cars at KOH? Even the top 20?
Oh, and how many of the those cars were XP !
I like both xp and x3! They are both good cars, and i think we all agree, Polaris got stagnant and didn’t really improve the car enough in places it should have?! So now they are playing catch up to the X3 in design, performance and reliability.
The long travel RZR is a big deal in the right direction for the XP car. A few of us have already known the good in the long travel since we tune these cars with aftermarket long travel and shock set ups. But these cars are only out and around in very small numbers since the expense is so high.
Still, as suspension goes, the base shock set up is what’s is all about on these new cars, Period! A good shock set up for this car will really help it shine. The Dynamix system sets a base static position, then just adds a little more firm in A few situations. It is not making huge adjustments! So it IS a POSITIVE for the car. It doesn’t need to do a lot, just a little.
And NO, there donsnt need to be a Dynamix rebound adjustment. Not ever! If the car is set balanced, with the rebound valving done right to start, then there is no reason to mess with it later. Some off us just know how to valve the mains better than others.
The X3 is still a great car! Polaris is playing a little catch up to try and have a car in the same category. The xp S long travel should help put them there. It’s not way better, or even better than the x3 long travel. But its same category comparable as far as Suspension and horsepower goes.
I have tried to get ahold of you forever. You helped me with my X3 XRS suspension and it is still nose diving. To tell you the truth the last time we spoke I wrote down your instructions on how to fix this on a sticky note and lost it. Can you please help me with this problem. Thanks again.
But I think you should do some reading to understand the difference between linear and progressive.

Lovin the velocities. Thanks Ed
