I recently purchased the above sled and would like to widen the ski stance as I will not be using it in the mountains and would like the added stability. The Mountain version was purchased due to the 144" track and the fact that where it is used there are few groomed trails. I understand that I will need to replace the radius and tie rods, would the shocks need to be replaced as well? How about the anti-roll bar (sled isn't at home to check if the Mountain version comes with one) I would imagine that if it didn't come with a anti-roll bar one should be added. If buying used parts would they have to be from a Sx Viper or which other donor sleds will be compatible? Thanks for your help in advance.
