Units do not have integrated stud protection but accessory kits are available. Units built with pre-
studded tracks (Ice Ripper/Storm) will come from the factory with the stud protection installed.
Stud protection kits are designed to work with studded tracks that have no-greater than 0.375 in
(0.953 cm) of stud penetration (that is, distance of the stud above the lug-tip). Polaris does not
recommend studding anything above a 1.352 in (3.43 cm) Cobra track, although the stud
protection will work on a 1.6 in (4.06 cm) Cobra track on 146 models.
