Independent suspension system promises good traction and smooth ride

A lot of trucks and Sport Utility Vehicles (SUVs) are using this independent rear suspension system, boasting of 2 springs to ensure the vehicle’s wheels move independently of one another, without causing harm or affecting the position and angle of other wheels. With this type of suspension system, smooth and exciting road experience is guaranteed. Despite the numerous benefits car owners can enjoy while using the independent suspension system, there are also few setbacks caused by it.

What is an independent rear suspension system?

In its simplest form, the fully independent suspension system refers to suspension system found in a vehicle where every wheel on similar axle is allowed to move vertically and independently when plying the road. It is the direct opposite of beam axle system, where there is a linkage between the wheels. This type of suspension engages the services of the right and left sides of the system to be linked with few mechanisms such as anti-rolls bars. While this anti-roll bar isn’t interested in linking their motion together, it ensures the spring rates of the right and left suspension are effectively tied together.

This type of suspension system connects the wheels to the differentials by half-shafts

The independent rear suspension unlike the independent front suspension, allows the rear wheels to play the major part whenever the vehicle is moving on the road. Although, most of the newly manufactured vehicles come fitted with Independent front suspension system, this hasn’t deterred the car manufacturers from using the other independent suspension type at their production lines. The independent rear suspension system utilizes the half-shafts in connecting the wheels to the differentials, in order for them to move freely without impacting on one another. This often helps in making possible good handling, noise suppression and quality ride.

vehicles with this type of suspension are often challenging to maintain

As a result of complex parts and advanced engineering, the price of independent rear suspension system is way higher than a regular suspension type. If you are really interested in this type of suspension, you shouldn’t mind coughing out some money to enjoy its benefits.

Rear suspension weight

Weight is often placed on vehicles equipped with this type of suspension system. As a result, there is a possible issue of understeer from its independent movable wheels and heavier suspension.

Consequently, this can cause problem for rear passengers and the vehicle as a whole, especially when the driver takes turns at high speed.

Straight-line road-trip

Independent rear suspension system may be a perfect choice for approaching corners but its performance rate on straight road isn’t impressive enough. On this type of suspension system, every wheel can easily and independently get lifted from the surface, which could adversely affect its traction. There is also the possibility for uniformed loss of driving power while in vehicle equipped with independent rear suspension.

Final note

Independent rear suspension system has proven overtime as an ideal choice for off-road capability as well as high performance ride. While it might offer few worrying drawbacks, car owners should understand that there isn’t any perfect suspension system out there.
