Im looking to get tunnel stiffeners ( fish bones ) for my sks. Will they fit right? I know they fit on pro-x's, but am unsure on my sled. Anyone have them?? Also what color would look best, yellow?

Just for clarification those are different than the Pro-X fishbones and Pro-X's have them stock.

the ones from pure polaris will fit on there but you may have two cut the tabs a little. I have the same fishbones on my rmk 144 and it is the same tunnel as your sks so you should not have a problem. o ya I think red would look the best on your sled. thumbsup.png

I have the red ones on my '04 RMK. The hardest part to installing them was using a hand riveter for the rivets. Find yourself a pneumatic riviter when you go at it....trust me! They fit no problem, but be sure to check the clearance between the track and the newly installed rivets. They may be a little close. Also you have to flatten out the little bumps in your running boards so they fit right. Lay them in place and then trace out the location with a pencil. That will show you which ones that need to be flattened. A good piece of heavy steel for the bottom and a flat faced mallet worked well for me.

The finish on them is pretty good too. 6500 miles later and they are just starting to show some wear.

Can someone post some pics of these on a Switchback or RMK chassis? Thanks a lot.
