Suspension kits usually refer to the system of springs and shock absorbers. They connect the vehicle frame and the wheels to control the relative motion between them.

Benefits of Suspension Kits

The Suspension Kits basically serve two purposes:

  • The suspension in a vehicle has to keep the contact between its tires and the road with maximum possible friction so as to provide it steering stability, a better control while moving and make the driving easier and safer.
  • It also makes the riding for the occupants of the vehicle comfortable and fairly well isolated from bumps, vibrations and noise.

How Does a Suspension System Work?

The common suspension kits for most of the popular cars include four lowering springs, four shock absorbers and the bushes. The chassis is attached to the wheels of the vehicle wheels through suspension kit and bushes.

The suspension kit or a suspension system controls the feeling of the vehicle while driving on the different types of road surfaces. The functioning and performance of the individual components in the suspension system will affect how your vehicle will respond to various road conditions. If the road is rough, the best suspension will transform all bumps and dips into a soft and smooth ride. The effectiveness of the suspension kit will determine how it makes your ride smoother and driving safer on bumpy roads and rough terrains.

Components of the Suspension Kits

Your suspension system basically controls the quality and comfort of your ride. It has mainly two sets of components that make your ride smooth. These are:

Springs

As the vehicle moves, it will inevitably endure bumps and dips on the road. These variations result vertical forces through the wheels. Humps force the wheel to move upwards, while pits make them go down. The springs in the suspension absorb these forces and try to get the vehicle back into a balanced position. The automobiles normally use three types of suspension springs:

  • Coil Springs – It is wound in the form a spiral. These springs are the best for absorbing up and down forces, but they cannot deal with a sideways motion. This type of spring is used on most cars as well as on the front of some SUVs and trucks.
  • Leaf Springs – These are made of a stack of steel strips. All strips or leaves are curved, flex up or down and absorb the forces over the uneven paths. Such springs are primarily used on rear – wheel drive vehicles, rigs, heavy – duty trucks, some SUVs and vans.
  • Torsion Bar – Torsion absorbs the forces or energy as it gets twisted. One end is firmly fixed whereas the other one is linked to the control arm of the vehicle. The torsion bar twists with the forces and rotates before spinning back in the opposite direction. These are mostly used on front – end suspensions, in many automobiles.

Shock Absorbers or Dampeners

Based on the Newton’s third law of motion, when a suspension spring gets an upward force, it reacts and releases an equal and opposite downward force. The downward reaction makes the spring to bounce back. The dampener or a shock absorber works to smoothen or dampen the vibrations and shocks in the spring. A shock absorber acts in a way similar to a cushion that makes a jumping ball falling on it almost still. Shock absorbers also control unwanted suspension motion such as an excess body roll, extreme pitch and dive, and the undesirable floating or swinging movement.

Tokico shocks are known for their quality. They are leaders for their twin-tube low-pressure gas shock absorbers and electronically adjustable shock absorbers. In fact, shock absorbers play a really critical role in suspension kits to keep your vehicle holding the road. Besides the performance and safety, the shocks significantly influence the quality of ride.
