I ride a '99 Summit X 670 with a 144" track with SLP powder pros. I love to ride the deep powder. But when there is more that 3 feet of it I can shred for a bit but end up stuck in a large trench. I have noticed that my skis pull the front of my sled to the top of the snow but my rails drag the back of my sled down. I am not sure how much travel it has but I know it is not enough. I already have 1 1/2" drop brackets. Is there any thing else I can do to increase my travel?
