Khaos Rails on a Regular Pro RMK

[JuniperVilla]

Ice age 162 khaos style.

On a 155 tunnel. Now that would be dope

 

[damx]

Nope a 163.

 

[kylant]

so which hole in the tunnel are you guys running in?

it was also mentioned earlier, having Andy lengthen the FTS shaft. I will ask him if he can do this. My shocks are there now getting shortened (front) and serviced.
If it is possible, will the FTS spring be long enough?

 

[kylant]

just talked to Andy at GSR. he does not think it is possible to lengthen the standard FTS shock to work on the khaos.

You just end up with a new shock.

It’s hard to cut anything longer.

The short track shock is around 1” longer, send andy one of those to shorten to khaos length.

I know, but replace the rod with a longer one...

what is this short track shock you speak of?

 

[Sheetmetalfab]

Pro ride rush or axys pro x or switchback front track shock.

Hundreds available on ebay.

Remote resi clicker Walker Evans (with hose to resi) clamps to rail with extruded aluminum clamps.

Installed 162/163 IceAge Khaos rails on my Pro last night. The bombers are a piece of work.
Utilizing the stock shock and limiter strap. It dropped the rail 3/8” and still allows preload on the shock, it shouldn’t top out.
I believe the Khaos opens it up 1” so it’s in between. I’m going to give this a try before I extend the shock and limiter strap. Might be the ticket.

Ya I think together with the khaos rails and raptor kit is the ultimate combo, or either one independently will be a step in the right direction.

Did you ever get a chance to see how well the setup works? About an hour away from ordering the raptor setup and a set of good used rails.

 

[Empire087]

bringing this back up top, very ready to do this, would like some more playfulness if it works well.

I orderered the Raptor Khaos kit --> longer limiter strap, extended FTS rod eyelet, shaft holding tool for $100
163" Ice Age Khaos rails, used Arctic cat 8" wheels

Also installed a 190# RTS spring (Khaos uses a 180#, stock ProRMK RTS is 210#) that I had laying around

It's all installed. With zero traction and the track spinning, its making the front end feel light. We are supposed to get more snow here todayy/ tomorrow. Should have a better report then.

Finally took it out for two days of riding........ WOW! If you are looking for more playfulness...... Do it. The feeling on the skis is lighter and able to change direction better through running board inputs.

The sled defiinitely wheelies more and front end feels a lot lighter on climbs--- so if you are a chute slayer, this might not be the best option. I'm not a climber/ highmarker. My riding style has been described by others as "****-holing", I like finding drainages and tree riddled routes to ridgelines where I''m spending as much time traversing horizontally as I am straight up.

The other interesting thing I found with the wheelieing while climbing--- it's NOT a trenching wheelie, leading to a stuck. Now, I left some massive looking "turbo trenches" (normally aspirated), but did NOT get stuck.

I am sold on the geometry.

 

[Murph]

I would not have believed such a small change would make such a big difference.

After coming off 5 39” Axys 800s— the 36” Axys 850 with Khaos 163” geometry is almost as big a maneuverability step as a ProRide to Axys.

This thing is awesome normally aspirated— might be too much of a handful under boost.

 

[TRS]

They are pretty awesome. I used my stock front track shock and limiter strap in stock form. Changed out the rear track shock spring to a 190*.

 

[Pws1102]

TRS did you install this on a pro rmk. Not a axys chassis?

 

[Pws1102]

I got iceage 163 khaos rails and raptor conversion kit. I measured the front mounting bolt with the factory rails, 11.5 inches from ground. I installed khaos rails with stock limiter strap and shock. It still measures 11.5 inches.. I installed the raptor shock extender and started on the limiter strap only to find the raptor strap is shorter than my stock pro rmk strap. From what i can tell on a pro rmk install khaos rails and the mount the skid in the lower assault hole and save $100 bucks on the raptor scam

 

[greasemonkey3406]

The sled isnt going to sit higher. Measuring from the ground to the mounting bolt isnt going to show anything.

 

[damx]

And the raptor limiter strap has to lengths to it. Stock and khaos.

 

[Pws1102]

I measure the skid sitting pn the concrete floor. If the skid Is going to sit lower on the tunnel. Then sitting the skid on the concrete it should measure higher

 

[Pws1102]

I have the limit strap in the longest position and it's still shorter than my stock limit strap that I was running
