A vibration dampening suspension device (10) for isolating a truck cab (1) from the force vibrations of a vehicle frame (2), which includes an impact plate (12) mounted to the truck cab (1), and a support plate (11) mounted to the vehicle suspension (4, 5). The device (10) further includes a link member (64) pivotally interconnected at one end (68) with the support plate (11) at a support pivot (82), and a lever member (66) with a first end (72) pivotally interconnected with the impact plate (12) at a main pivot (88). The link member (64) is pivotally interconnected with the lever member (66) for rotation of the lever member (66) with respect to the main pivot (88) during compression of the shock absorber (90) when the supporting body (2), suspended body (1) and device (10) are in a dynamic condition. A hydraulic shock absorber (90) is provided with a first end (92) pivotally interconnected with the lever member second end (74) at a shock pivot (89) and a second end (94) pivotally interconnected with the impact plate (12) at a pivot spaced from the main pivot (88). An air spring (50) interconnected between the impact (12) and support (11) plates, and a torque arm (44) pivotally interconnected between the impact plate (12) and support plate (11), are also included.
