Guys, figured we would chime in is this is something we have spent hundres of hours working on as well as talking to customers from all over the world. There are definately a number of ways to go about achieving some or all of the Khaos geometry but one critical component to consider also is shock packages and ride quality.
We consider a full Khaos converted sled as having full OEM khaos geometry components as well as on par or higher quality shocks as the OEM velocity shocks that come on the Khaos sleds.
There are 2 ways to achieve a partial Khaos geometry, as well as a way to get full chaos geometry without nearly the proper ride quality.
The 2 partial combo's are Either running just Khaos rails on an RMK, this is about 1/3 of the geometry change as mentioned above. The second combo would be running something like an extended shock eyelet on an RMK rail along with a khaos length limiter.
A full conversion done with our rails (or OEM takeoffs) and some sort of longer shock eyelet as well as khaos limiter straps may achieve full khaos geometry, but the end ride results and performance are not deserving of the full Khaos name in our opinion. The front track shock is being put into play a lot more with the khaos geometry and utilizing an OEM walker evans monotube shock is just not going to perform like the higher end options. Also the rear track shock now is handling a sled setup that is setup to transfer more aggresively so the valving is not matched for this. The best way we can describe this is the Chevy S10. Its a "truck", classified as a truck, has a cab, bed, 4wd etc etc but its no diesel 1 ton. Just because you have all the khaos geometry doesn't mean things are on even close to the same playing field.
After a long winter of testing and working with the team at Fox as well as riding lots of other suspension combinations it became very apparent that hitting the geometry was important but a shock package built to match was absolutely critical for true 'performance' of the kit. One thing to consider also when weighing the slightly more costly kit using full shocks vs a modified or mismatched shock package is all around performance. Having put thousands of miles on just about every shock package offered as well as numerous modified OEM WE shocks, we can confidently say the '21 Fox packages are the best riding shocks we have put time on. Fox is a massive company with manufacturing/tuning resources that dwarf most other snow companies. This really shows this season on 2 fronts, first being performance. The internal bypass as well as QS3 package provides the most broadly capable shock setup in a simple to adjust and understand package we have ever rode. The second is price, because of their size and ability to manufacture in volume pricing is incredibly affordable on the 1.5 QS3 package. At $995 this shock package is on the low end of cost but competing with the highest end shocks on the market for a fraction of the cost. The Float 3 Evol and IQS packages also add even more range and adjustability into the package at a slight increase in cost.
Also an easy to overlook feature but something we love is the Lockout option on the rear shock on all of the Fox shocks. This provides the ability to easily tame the Khaos down and keep the skis planted on the snow better then an RMK with the flip of a switch. This means you can go from mild to wild with the flip of a switch!
For the guys who have purchase or are going to purchase one of our Chaos conversion kits with the Fox shocks, we cannot wait for people to get out and ride this setup. It is hard to describe the jump in performance vs even the best OEM option from Polaris. You guys are in for a treat!
