Anybody have a chance to measure to see if it will fit? would be nice to have the lockout portion for deep hill climb days. anybody have the eye to eye measurement?

part number 3704-218

Probably work but probably have to change that control rod too if it's different length, heard the 18 shock is longer perhaps the rod too?

Based on what I saw in the Fox Booth at Jackson last year, I'd wait see what they come out with mid-season. But that's just me.

Just think how much nicer it would be to push a button on your handlebar rather than get off the sled and turn all those QS dials by hand.

Which Ski-Doo model has push-button compression adjustable shocks on it?

I'd be happy enough to not need the stupid pump everytime I want to make an adjustment. push button is great, but I'd rather turn it by hand just for the fact there is less to go wrong.

how does the push button one work? would be slick if it doesnt add weight.

Small servo motor on each shock that turns the compression valve on the reservoir. The prototypes that were mounted on the sled were a little on the large size, but the engineer I was talking to said they were components they had laying around and used for testing. Functional testing was complete and he said they were working on sourcing some smaller, more compact parts to keep them as small as possible for both weight and durability. The shocks were mounted on a sled so I can't tell you how much more they weighed comparative to a standard shock. My guess would be an additional 1/4lb per shock when it's all said and done plus wiring and button. He said actual product should be available to the public after the 1st of the year. I forgot to ask about the details of how they are powering the system.

Adjustable accessories
A remote coupler block adjuster is available for 2018, allowing a rider to quickly adjust the transfer right from the handlebars. The adjuster on the left-hand grip changes the block in back from coupled to uncoupled and back with just a twist of your hand. Also available for 2018 is an adjustable windshield that can be adjusted four inches, from medium height (19 in.) to high height (23 in.). Check out the new driver-angled footrest platforms from Ski-Doo accessories as well!

The 2016-2017 skid should just need the rear QSRL shock. We have them on hand. The older skids will need a different length control rod, we have those as well.

Yes i agree but my OP was looking for the lockout most for the big Dieck hill climbs.

Lithium ion cells charged by an inverter/wheel mounted in the rear suspension on the shocks cross bar.

so it looks like the 18 shock is 17"with a 15.4" down rod and the 16 shock is 16" with a 14.25" down rod.

I bought one for my 13 and don't see any reason it won't work. Looks to me like they increased the length of the downrod when they made the mounting pont for the front arm higher on the 16s. Shock is 16.5 center to center of eyes.

I feel like this is a huge upgrade for 300$ not only do you get a much improved shock you get a lockout. I'll be ditching my kiss coupler

yeah i don't see the point in changing the length of the control rod. all that is going to do is change the angle of the scissor.

this pic compares the 15 to 16 rails. you can see why they increased the length of the rod. i didn't measure the shock on my 16 because it was up in my loft but i assume its the same length as my 13 and the new 18 MC shock that i took a pic of. if you check the specs on arctic cats website the pro climb has had the exact same rear suspension travel since it was introduced in 2012

the rear has changed a bit over the last 5 years, rails, and arms. I will have the answer in a few days as im on a 16.

I had a brain fart.. forgot that you guys below the border don't get the shaft like we do in Canada.. $580 up here. I'd save about 200 bucks buying in the states versus up here.. unbelievable.

just put it on and my 16 needed the longer control rod, other than that is just bolts in. adjustable rear damping and a lockout without a rear coupler. now all I need is snow to see how it works.

so does the rear bumper sit a little higher after install i.e. more running board clearance?
