A snowmobile rear suspension is shown comprised of a linear force element (LFE) positioned outside the envelope of the snowmobile endless track. The snowmobile frame includes a chassis mounted to a tunnel, where the chassis includes a central mounting bracket. The LFE is attached at one end to the bracket and at the other end to a bell crank. The bell crank is operatively connected to the slide rails. When the slide rails collapse in normal operation, the bell crank strokes the LFE, and the suspension is progressive throughout the range.
What is claimed is: 1. A snowmobile, comprising:a chassis comprised of a tunnel and a subframe, the subframe being structurally and fixedly mounted to the tunnel;slide rails;endless track coupled to the slide rails;at least one front linkage operatively connecting the slide rails to one of the tunnel or the subframe; andat least one rear linkage operatively connecting the slide rails to the tunnel.
