GM Shock Absorber

A GM shock absorber is a main component of the suspension system of a General Motors vehicle. As the name suggests, the main role of a shock absorber is to absorb the suspension shocks due to vibrations and load. Basically, a shock absorber is a hydraulic-pneumatic shaft that is comprised of a piston and a cylinder. Inside the cylinder wall, hydraulic oil and trapped air can be found. The hydraulic oil and trapped air serve as cushions that absorb the compressive force of vehicular vibrations. When the car is running, it continually (although in a subtle manner) shifts it center of gravity. This shifting of center of gravity is particularly very pronounced when the road is riddled with bumps and cracks.

Aside from the relatively subtle but continuous shift in the vehicle’s center of gravity, the vehicle also oscillates vertically and horizontally. Admittedly, these oscillations or vibrations are primarily because of the continuous shift in the center of gravity of the vehicle. Since an automobile is comprised of several parts, vehicular vibrations are inevitable – regardless of the flatness of the ground. As long as the vehicle is running, it will always have a degree of corresponding oscillation. The engine vibrations, wheel motion, weight of load, and ground contour all contribute to vehicular oscillation.

Vehicular oscillation or vibration is minimized by the suspension components. Shock absorbers such as GM shocks are installed on all the wheels of the vehicle to compensate for vehicular vibrations. When a wheel encounters a bump on the road, it has a tendency to fly off the ground. However, this is prevented by allowing the compressive force of vibration to be absorbed by the shock absorber. The inertial energy of the vehicle is temporarily and partially transferred to the shock absorbers.
