Can you post a picture of each mounting bracket position(front and back) without the jack attached. Looking for correct location. I have the same front bracket already. I'm sure I can come up with your same rear bolt. The older original rear bracket doesn't seem to fit my new sled side tunnel locarion well. Thanks for the info and picture!
Sorry, but the sled is jammed into the trailer with other sleds and to get some better pictures would mean unloading them. Not quite ready to fire them up for the season just yet.
Plant the u-bolt just below the track (inside the tunnel) by an inch or so, and make sure that there are no extra threads sticking through the nut on the inside of the tunnel. If the track gets to flopping a bit at high speeds it could shred the edge. A 1/4" nut is thin enough that it should never be a problem if it is located under the track by a little bit.
As for the rear bolt, I located mine just back of the top idler wheel about 3.5"-4" higher than the track. This is due to the 3" paddle and track thickness. At this location, the suspension would have to be completely flat and the track would have to be angled upwards to come into contact with the nut. Again, I made sure there were no extra threads beyond the end of the lock nut that I used. This also puts the jack at a low enough angle that it does not interfere with jumping from one side of the sled to the other.
I got my jack when I had my Yamaha Apex. Now that thing was heavy. I have had the same jack since then, on every sled I have owned. When folks ask why I pack such a heavy thing like that jack I remind them that it only weighs 7 pounds and I have never had it interfere with my riding. And, no, I am not a trail jockey. For the 1500 miles, or so, that I put on my sled every winter I would imagine that about 30% of them are on trails. Trails get me to where I bail off for the day and go boon docking. 20-30 minutes down the trail to bail off and spend the next 6 hours exploring and riding the untouched areas we can find is a perfect day for me.
I have never experienced a situation that the jack did not compact enough snow to lift my sled out of hole. So, for the folks that don't think they will work or are a waste of time, that is their choice. When I get unstuck in pocket deep powder in the trees and they are still shoveling their butt off I will come watch and give some verbal encouragement. No problem.
For being in my mid 60s, jack and I are doing fine!!
