Introduction To Struts
A strut is a critical component of a vehicle’s suspension system, responsible for supporting the weight of the vehicle and maintaining the alignment of the wheels. It is essentially a shock absorber mounted within a coil spring, designed to absorb bumps and shocks from the road, thereby providing a smoother ride for the occupants. Struts are commonly used in the front suspension of vehicles, but they can also be found in the rear suspension of some cars. Their primary function is to:
- Support the vehicle’s weight
- Absorb shock and vibrations
- Maintain wheel alignment
Struts are designed to work in conjunction with other suspension components, such as coil springs, control arms, and steering knuckles, to ensure that the vehicle remains stable and responsive to steering inputs.
How Struts Work
Struts work by using a combination of a coil spring and a shock absorber to control the movement of the vehicle’s wheels. The coil spring supports the vehicle’s weight, while the shock absorber dampens the oscillations that occur when the vehicle hits a bump or pothole. This is achieved through a process known as damping, where the shock absorber converts the kinetic energy of the moving suspension into heat energy, which is then dissipated. This process allows the vehicle to maintain contact with the road, thereby improving stability, handling, and ride comfort.
Types of Struts
There are several types of struts available, each designed to meet the specific needs of different vehicles and driving conditions. Some of the most common types of struts include:
- MacPherson Struts: These are the most common type of strut and are used in the front suspension of many vehicles. They are characterized by a coil spring and shock absorber mounted within a single unit.

- Toyota Struts: These struts are designed specifically for Toyota vehicles and have a unique design that sets them apart from other types of struts.
Introduction To Loaded Struts
A loaded strut, on the other hand, is a strut that has been pre-loaded with a coil spring. This means that the strut is designed to work in conjunction with a coil spring that is already mounted on the strut, rather than being a separate component. Loaded struts are designed to simplify the installation process and reduce the risk of incorrect installation. They are commonly used in vehicles that have a strut-based suspension system, such as many modern cars and SUVs.
How Loaded Struts Work
Loaded struts work in a similar way to traditional struts, but they have the added benefit of a pre-loaded coil spring. This means that the strut is designed to work in conjunction with the coil spring to provide a smoother ride and improved handling. The pre-loaded coil spring also helps to reduce the risk of coil spring damage during installation, as it is already mounted on the strut.
Advantages of Loaded Struts
Loaded struts have several advantages over traditional struts, including:
- Simplified Installation: Loaded struts are easier to install, as the coil spring is already mounted on the strut.
- Reduced Risk of Incorrect Installation: The pre-loaded coil spring reduces the risk of incorrect installation, as the strut and coil spring are designed to work together.
