Default Coupled vs uncoupled suspension

We have an XLT SP with x12 suspension and an XLT SKS with 136 x10 suspension. The x12 is a boat anchor in anything more than a foot of snow. This summer I'm going to long track both of them to 144. Optimally, I would like to find a couple of Edge 144 skids. If I only buy one skid, I'll just put 136-144 extensions on the x10. I might even replace the x12 with a 136 skid and put extension on that one too.

I was just reading a thread about coupled vs uncoupled suspensions. Is it accurate to say that an uncoupled suspension is better for deep snow than a coupled suspension (since the angle of the skid can change to conform to the ground better)?

I was just reading that an Edge 136 suspension is coupled, and you have to get a 144 to get an uncoupled Edge suspension? Is a 136 xtra lite suspension uncoupled? What about a 136 Pro X? Would a 136 xtra 10 suspension work better in deep snow than a 136 Edge since the xtra 10 is uncoupled and the Edge is coupled?

What suspension would work the best in a wedge chassis for fairly deep snow? I'll be using 8 tooth drivers with 1.75 track. I don't want to try to high mark any big hills, I just want to be able to go off trail and be able to trudge through some fairly deep snow.

I had an XLT SP (97 model) and installed a 133 (X-12 SKS) rail and 136 x 1.25 track, and built a small rail extension to make it work. Do not go any longer than 136 on the X-12 or you will slam the track into the back of the tunnel. Concerning the X-10, Holz's initial rear skid bolted rignt in. Their torque arms and an X-10 136 rail. My recommedation is to leave the X-12 alone and ride the trails.

Try to work with the X-10. Bolt on 136 rails, take out the rear coupler blocks, and see how it goes. Try Holz and see if they have some older rear skids left. The Indy Lite skid is not coupled and will bolt in with some different torque arm to tunnel locations.

I would recommend against 121 to 136 rail extensions - a quite long moment arm working against the four mounting bolts.

Coupled suspensions are designed to thrust the machine forward with minimal weight transfer-minimal ski lift, just the opposite with the uncoupled suspension.

Lots of blather here, hope it makes some sense. Cheers.
