A support structure for a track system is disclosed. The support structure has leading and trailing linkages which are pivotally connectable to a frame member of the track system through, respectively, leading and trailing pivots. The leading linkage is pivotally connected to the trailing linkage through an intermediate pivot. The support structure has at least one biasing assembly. Leading, intermediate and trailing support wheel assemblies are connected to the support structure, which is adapted to move such that when the leading support wheel assembly moves in a first direction, the intermediate support wheel assembly moves in a second direction, and the trailing support wheel assembly moves in the first direction. A track system having the support structure and a vehicle having the track system is also disclosed.

A snowmobile includes a chassis comprising a bulkhead and a tunnel, a front suspension coupled to bulkhead, a rear suspension coupled to the tunnel, and slide rails coupled to the rear suspension.

A modular frame for a track system is disclosed. The modular frame includes an upper frame member operatively connectable to an axle of a vehicle and removably connectable to a first lower frame member. The first lower frame member is configured to connect with at least one of a support wheel assembly and an idler wheel assembly, and connection of the upper frame member to the first lower frame member confers a first lower frame member-specific function to the track system. Another modular frame, track systems having the modular frames, tensioners and track systems having the tensioners are also disclosed.
