I'm not sure what you are asking.. if you want to get the sled on it's side easier, like when you want to side hill, narrowing the ski stance to the narrowest setting will help that a lot. The narrower it is, the easier it is to pull onto it's side.
Is yours a 550 or the 600? The 600 has the RMK style rear suspension where the 550 has the Indy style parallel slide rail.
Either sled can side hill, it's all in developing the technique.
