How does the front strut or shock absorber work? A loaded front strut assembly, often called a MacPherson strut, consists of a coil spring and a shock absorber. The coil spring is in place to support the weight of the vehicle and to absorb large bumps. It allows the front suspension to travel up and down so that the vehicle body can remain stable.

They are mounted at the top of the chassis at the front-end of most front-wheel-drive vehicles. However, struts are not limited to front-wheel-drive configurations. The primary purpose of the struts is to support the weight of the vehicle while also absorbing surface impacts and ensuring a smooth ride.
How does a strut on a car work?
Struts provide structural support by connecting the upper strut bearing to the lower ball joint. This allows the strut to move as the tire is turned. Your vehicle's suspension is in charge of keeping your tires in contact with the road surface at all times. Struts are a dampening device for your vehicle.
Do front struts turn with the wheel?
Many front strut mounts also contain a bearing which acts as a steering pivot – so as you turn the steering wheel from left to right and vice versa, the strut pivots on the strut mount, controlling the angle and alignment of the wheels.

The strut assembly also contains an upper mount, which includes a bearing that allows the strut to rotate, and a dust boot that protects the damper from dirt and debris.
What is a MacPherson strut?
A typical MacPherson strut assembly contains a damper, a coil spring, and a top mount with an integrated bearing. Each strut assembly mounts between a steering knuckle and the car’s body. The struts act as a structural part of the suspension system, and the top mounts provide pivot points for the vehicle’s steering.

The most common arrangements include: MacPherson Strut. These days, the most common type of front suspension system is a MacPherson Strut.
What is a torsion bar?
Instead of using leaf springs or coil springs, a torsion bar suspension relies on a pair of torsion bars (one on each side of the vehicle) to absorb road shocks and support weight. Each torsion bar connects to a lower control arm at one end and the vehicle’s frame at the other.
Why do sway bars work?
When the vehicle is cornering, the sway bar twists to prevent body roll and improve handling. The sway bar also adds an extra level of stability when traveling over imperfections in the road. At each end of the sway bar, there’s an end link that attaches to the control arm or strut assembly.

The end plug is used to seal the tube end of the gas spring and is where the tube end fitting attaches. In the case of Camloc Gas Springs the end plug is also where the Vari-Lift valve can be incorporated. The Vari-Lift valve allows the release of the Nitrogen gas from the spring, which reduces the gas spring force. This feature is useful in allowing the gas springs to be fine-tuned to the application.
