A snowmobile is described having a frame with left and right sides with left and right suspension assembly disposed thereon. Left and right spindles are connected to the left and right suspension assemblies. A left ski is pivotally attached to the left spindle and a right ski is attached to the right spindle. Rotation of the left and right spindles alters the ski stance of the snowmobile. The stance may also be altered in other ways, which are also disclosed.

A snowmobile, comprising:a frame having a right side, a left side, and a centerline; right and left suspension assemblies pivotally connected to right and left sides of the frame respectively; and right and left spindles rotatably connected to the right and left suspension assemblies respectively, each spindle in an initial orientation, each spindle having an upper portion and a lower portion, wherein the upper portion of each spindle defines an axis of rotation, wherein the lower portion of each spindle has a transverse centerline offset from the axis of rotation; wherein the distance between the transverse centerline of the right spindle and the transverse centerline of the left spindle is alterable by at least one of (1) rotation of the right and left spindles by 180° and (2) swapping of the right and left spindles for one another while each is kept in said initial orientation. 2. The snowmobile of claim 1, wherein the transverse centerlines are positioned approximately equidistant between right and left sides of the lower portions of the spindles.3. The snowmobile of claim 2, wherein the upper and lower portions of the spindles are tubular members connected perpendicularly to one another.4. The snowmobile of claim 3, wherein:the upper and lower portions are straight tubular members, and the upper member connects to the lower member at a position that defines the offset between the axis of rotation and the transverse centerline. 5. The snowmobile of claim 2, wherein:the upper member connects to the lower member at the location of the transverse centerline and the upper member includes a bend therein to offset the axis of rotation from the transverse centerline. 6. The snowmobile of claim 1, wherein the axis of rotation is offset from the transverse centerline by distance between about 0 to 25 mm.7. The snowmobile of claim 6, wherein the axis of rotation is offset from the transverse centerline by distance between about 5 to 20 mm.8. The snowmobile of claim 7, wherein the axis of rotation is offset from the transverse centerline by a distance of about 16 mm.9. A ski leg for a snowmobile comprising:an elongated body having upper and lower portions, a front side, a rear side, a left side, and a right side, the lower portion suitable for connection to a snowmobile ski; a first protrusion projecting from the upper portion front side of the body, wherein the first protrusion is suitable for connection to an upper suspension assembly; a second protrusion projecting from the lower portion front side of the body, wherein the second protrusion is unable for connection to a lower suspension assembly; and a third protrusion projection from the rear side of the elongated body, wherein the third protrusion is suitable for connection to a steering arm; wherein the first and second protrusions define an axis of rotation passing therethrough, and wherein the lower portion of the elongated body includes a transverse centerline that is offset from the axis of notation to one of the left side and the right side of the elongated body by a redetermined distance. 10. The ski leg of claim 9, wherein the transverse centerline is positioned approximately equidistantly between the right and left sides.11. The ski leg of claim 10, further comprising:at least one spacer attached to one of the left side and the right side of the lower portion of the right ski leg; at least one spacer attached to one of the left side and the right side of the lower portion of the left ski leg; wherein the distance between the transverse centerline of the right ski leg and transverse centerline of the left ski leg may be altered by switching the at least one spacer of the right ski leg to the other of the left side and the right side of the lower portion of the right ski leg and switching the at least one spacer of the left ski leg to the other of the left side and the right side of the lower portion of the left ski leg. 12. The ski leg of claim 10, wherein one of either the right or left sides of the lower portion of the elongated body extends outwardly from the elongated body a distance greater than the other of the right and left sides to offset the transverse axis from the axis of rotation.13. The ski leg of claim 9, wherein the axis of rotation is offset from the transverse centerline by a distance between about 0 to 25 mm.14. The ski leg of claim 13, wherein the axis of rotation is offset from the transverse centerline by a distance between about 5 to 20 mm.15.
