Types of the Best Shock Absorbers

Shock absorbers are essential components of a vehicle's suspension system. They control the impact of bumps and rough roads to provide a stable and smooth ride for drivers and passengers. Here are the four main types of shock absorbers:

  • Monotube shock absorbers

    This type of shock absorber has a single cylinder containing high-pressure nitrogen gas. Monotube shock absorbers provide consistent damping, making them suitable for performance vehicles. They also have a quick response to changes in the road surface. Drivers experience better handling, stability, and a smoother ride.

  • Twintube shock absorber

    Twin-tube shock absorbers have two parallel cylinders. The inner tube holds the piston and the fluid. The outer tube acts as a reservoir for the fluid. Most vehicles come with twin-tube shock absorbers because they are affordable and provide a comfortable ride on smooth roads. However, they lose damping performance when heated.

  • Gas-filled shock absorbers

    Gas-filled shock absorbers have compressed gas, mostly nitrogen, in the chamber. The gas prevents the formation of bubbles in the oil. The gas also increases the pressure in the shock absorber, making the vehicle stable. Gas-filled shock absorbers are durable and improve handling. Off-road vehicles and trucks use gas-filled shock absorbers.

  • Coilover shock absorbers

    Coilover shock absorbers combine shocks and springs into one unit. The spring wraps around the shock, creating a compact assembly. Coilover shock absorbers adjust the ride height and preload. They are available in monotube and twin-tube designs. Coilover shock absorbers are popular in racing and high-performance vehicles.

Specifications and maintenance of the best shock absorbers

Here are some common specifications to consider when buying car shocks and struts.

  • Size

    Shock absorbers come in different sizes. It is important to select a size that fits the car's model. A well-fitting shock absorber will be able to control the car's movements better. It will also be able to withstand damage for a long time. Size specifications are given in inches.

  • Type

    A vehicle may use twin tube shocks or mono tube shocks. The type of shock absorber used by the vehicle needs to be specified. This is because each type has its own advantages. For example, mono tube shocks are better for off-road conditions.

  • Mounting

    Shock absorbers are mounted in different ways. Some are mounted with bolts. Others are mounted with clips. The method used to mount the shock absorber needs to be specified. This is to ensure that it can be mounted easily.

  • Travel length

    The travel length of the shock absorber is also specified. Travel length refers to how far the shock absorber can stretch. When a car goes over a bump, the shock absorber stretches. A longer travel length gives a car a smoother ride.

  • Valve adjustment

    Some shock absorbers have valves that can be adjusted. The adjusted valve controls the flow of fluid inside the shock absorber. It allows the driver to fine-tune the shock absorber's response. Shock absorbers with valve adjustments are more expensive.

Maintaining shock absorbers is important. Good maintenance keeps the vehicle safe and gives it a longer life. Here are some tips for maintaining shock absorbers.

  • Visual inspection

    Shock absorbers should be visually inspected regularly. Signs of wear and tear should be checked for. The body of the shock absorber should be checked for dents. It should also be checked for oil leaks. Oil leaks occur when the seals are worn out.

  • Check the ride height

    The vehicle should be parked on a level ground. The distance between the ground and the vehicle should be measured. If the measurement shows that the vehicle has lowered, it may be a sign that the shock absorber is worn out.

  • Test the rebound effect

    The shock absorber's ability to control the vehicle's movement should be tested. The driver can perform a bounce test. This is done by pushing down on one corner of the car. If the corner of the car bounces up and down several times, it shows that the shock absorber is weak.

Proper installation of a shock absorber ensures good performance. The steps for installing a shock absorber should be followed as per the manufacturer's manual.

How to Choose the Best Shock Absorbers

There are various factors to consider when choosing the best shock absorbers. Below are some of them:

  • Vehicle type and usage

    When choosing a shock absorber, consider the vehicle type and its use. A heavy truck will require heavy-duty shock absorbers because they carry heavy loads. Also, if the vehicle is used for off-road purposes, it's best to use shock absorbers designed for rough terrain.

  • Driving style

    Consider the driving style when choosing a shock absorber. For example, a performance driver, such as a racing driver, will need high-performance shock absorbers that provide better handling and stability at high speeds.

  • Load-carrying capacity

    Choose a shock absorber with a load-carrying capacity that matches or exceeds the expected load. This ensures that the shock absorber functions well and increases its lifespan.

  • Height and length

    When choosing a shock absorber, consider the height and length. Choose a shock absorber with the right size and length for the mounting point. Also, ensure the compressed and extended lengths fit the vehicle's suspension travel.

  • Quality and brand

    Shock absorbers are an important part of the suspension system. Therefore, it's important to choose a shock absorber from a reputable brand and high-quality material. Quality shock absorbers provide consistent performance and durability, which helps save money on replacement and repair costs.

  • Adjustability

    When choosing a shock absorber, consider whether to choose an adjustable or non-adjustable shock absorber. Adjustable shock absorbers allow control of damping force, which can be adjusted according to preference or driving conditions.

  • Budget

    Consider the budget when choosing a shock absorber. Quality shock absorbers are more expensive but offer better performance and durability than cheaper models. Investing in quality shock absorbers is cost-effective in the long run.

How to DIY and Replace the Best Shock Absorbers

Here is a step-by-step guide on how to DIY and replace shocks:

  • Prepare the Vehicle

    Find a flat surface and park the vehicle. Turn off the ignition and engage the parking brake. Take the wheel chocks and place them behind the rear wheels. Get the vehicle jack and raise the front part of the vehicle where one will replace the shock absorbers. After that, place the jack stands under the vehicle for support and remove the front wheels.

  • Remove the Old Shock Absorbers

    Locate the shock tower nut situated on top of the shock absorber and loosen it using a socket wrench. One will find the shock absorber at the back of the wheel on trucks and pickup cars. At the bottom of the shock absorber, there are two bolts that one should remove using a wrench or ratchet. When the bolts are loose, one can use a pry bar or ratchet handle to push down and remove the shock absorber from the mounting point. Then, completely remove the nut on the shock tower and take out the old shock absorber.

  • Install the New Shock Absorbers

    Take the new shock absorber and align it with the mounting points. Then, carefully push it to the bottom and install the bolts. Tighten the bolts using a wrench or ratchet. Go back to the top and install the nut on the shock tower. Tighten the nut firmly using a socket wrench. Do the same process on the other side of the vehicle to maintain even handling and ride height.

  • Reassemble the Vehicle

    Put back the wheels and tighten the lug nuts using a wrench. Remove the jack stands and lower the vehicle from the jack. Once the vehicle is back on the ground, one can use a torque wrench to tighten the lug nuts to the manufacturer's specifications. One is now ready to drive the vehicle.
