No, struts and shocks are not the same thing. While both are crucial components of a vehicle’s suspension system, they have distinct designs and serve different functions.
The Core Purpose
At their essence, both shocks and struts are designed to smoothen a vehicle’s ride. They achieve this by dampening the spring oscillations of a car’s suspension system. However, the way they are constructed and the specific roles they play within the system are where their differences lie.
Shock Absorbers Explained
Shock absorbers, commonly referred to as “shocks”, primarily focus on absorbing and dissipating the energy derived from road irregularities.
Their main task is to ensure the tires remain in contact with the road, providing consistent handling and braking. Shocks are essential for controlling the movement of the springs and suspension, preventing excessive bouncing, and ensuring a smooth ride.
Understanding Struts
Struts, while also serving the purpose of absorbing road bumps, are structurally more complex. They are a structural part of the suspension system, often acting as a pivot point for the vehicle’s steering mechanism.
Unlike shocks, struts integrate various suspension parts into one compact assembly, including the coil spring, spring seats, and the shock itself. This integrated design means that struts influence a vehicle’s alignment and overall handling more directly than shocks.
Physical Distinctions
When examining a vehicle, shocks, and struts can often be differentiated by their location and appearance.
Shocks are typically standalone units, while struts are part of an assembly with the coil spring. Shocks can often be found at both the front and rear of a vehicle, while struts are generally located at the front.
