What are the benefits of a coupled suspension vs non coupled? How does it work and when do you want the suspension to couple? I'm only a rider and never really gave much thought into how everything worked. When I look at a snowmobiles rear suspension, no matter the brand, I basically see the same thing. Two rails, a shock in the front and one in the back, an A arm in the front and back. So what makes Ski Doos so much different and better than Yamahas?
Coupling helps the rear suspension "squat" and transfer the weight to the track so it can get traction. not sure if that is explained correctly but if it wasn't coupled all the weight would simply go back and the front end would easily go up. This something you want for off trailing to keep the front end up out of the deep snow.

I'm still trying to understand this myself and found the info on SKINZ ARC(adjustable remote coupling) helpful. Check out their website.

This video explains it pretty well

Similar to the comments above, in the mountains you want an uncoupled skid that is able to transfer weight to the back so the sled can get up on top of the snow. Typically you want a coupled skid for trail riding so the weight is transferred to the front of the skid giving the entire track length bite on the snow - and not just the back.
As for the Ski Doo skid; yes it has lots of features and is easy to adjust compared to most other skids. They have an easy adjustment to add/subtract tension to the torsion springs. On Nytros and Vipers there is a 3 position cam. Usually once that is set to your weight, it is left and no further adjustment is required. Skidoos also have an adjustable coupling block (this changes the moment of coupling) where most skids have one. In certain conditions the sled will behave differently if the skid couples earlier vs later. The fact that all these great ideas are incorporated into a skid without one grease fitting still boggles me.......
Keep reading, there is lots of info out there. Good luck.
