A snowmobile design, including a modular front suspension system and a stabilizer assembly, a lightweight frame structure and a drive train that reduces the center of gravity of the snowmobile. The modular front suspension system for a snowmobile that is substantially self-contained and self-supporting. The present modular front suspension system is assembled around a primary support structure, such as an extrusion or other structural member. The primary support structure can be easily attached to, or detached from, the snowmobile frame. The modularity of the present suspension system decreases assembly costs. A stabilizer assembly extends through the center opening and is mechanically coupled to the ski spindle housings. The chassis for a snowmobile includes a plurality of front structural members defining a motor compartment. A pair of independent, rear structural members are rigidly connected to the front structural members and extend rearwardly from the motor compartment on opposite sides of an endless belt channel. A protective shell extends between the pair of rear structural members and over the endless belt channel. The protective shell comprises a light-weight, resin based material that transfers substantially no loads between the pair of rear structural members. The snowmobile chassis further includes a rear suspension system extending between the pair of rear structural members. The rear suspension system transfers substantially all loads between the pair of rear structural members.
