What is the Difference Between Shocks and Struts?

Shocks and struts are both essential components of a vehicle's suspension system, but they have different functions and structures. Here are the main differences between them:

1. Function: Shocks, also known as shock absorbers, are hydraulic components that help minimize movement generated by the vehicle's movement, softening the impact from uneven or damaged roads, and providing a smoother, more comfortable driving experience. Struts, on the other hand, are structural components of certain vehicles' steering and suspension systems, designed to be much stronger than shocks since they are weight-bearing components. They also help dampen vehicle jolts and improve the vehicle's steering and alignment.
2. Structure: Shocks are individual components of the suspension system, while struts are a major structural part of the suspension system. Struts combine a shock and spring assembly in one unit that is part of the structural make-up of the vehicle, integrating numerous different suspension parts into one compact assembly, such as the coil spring, spring seats, shock absorbers, strut bearing, and steering knuckle.

In summary, shocks are mainly responsible for minimizing vehicle movement and providing a smoother ride, while struts are structural components that support and control the vehicle in motion, combining multiple suspension parts into a single unit.

Comparative Table: Shocks vs Struts

Here is a table comparing the differences between shocks and struts:

In summary, shocks and struts are both important components of a vehicle's suspension system, but they serve different functions. Shocks are individual components that help control excessive body and tire movement, while struts are major structural components that physically locate and control the movement of the knuckle/wheel/axle in three-dimensional space.
