A seat suspension includes a frame fixedly securable to a structure. A suspension assembly is operably connected to the frame. A seat support is adapted to receive a seat, and the seat support is operably connected to the suspension assembly. The suspension assembly includes a first elongate suspension bar slidably disposed on a pivot surface. The first suspension bar has a first end slidingly secured to the seat support and a second opposed end secured to a shock compensating device. The suspension bar is translatable relative to the pivot surface, wherein moving the suspension bar changes the shock compensation of the suspension assembly.
