Top 9 Shock Absorbers For Your Automobiles

Rough roads and worn-out shock absorbers can turn any drive into a jarring experience. Studies by the National Highway Traffic Safety Administration (NHTSA) show that worn suspension components can increase stopping distances by up to 20%, significantly impacting your safety. Interest: Don’t just suffer in silence! Believe it or not, your shock absorbers play a vital role in your car’s handling, stability, and overall comfort. So, how do you determine the right one? Here’s what you should know: 

  • Vehicle Compatibility: Ensure you choose shock absorbers designed specifically for your car’s make, model, and year. Most manufacturers offer standard replacements that match Original Equipment (OE) specifications.
  • Driving Style: Look for shocks with a lower damping coefficient (N⋅s/m) (e.g., 3,500 N⋅s/m) for softer valving and a more compliant ride.
  • Off-road Adventures: Prioritize durability with features like increased ground clearance (e.g., +25mm) and longer travel length (e.g., 500mm+) to handle rough roads.

Buying Guide For The Best Shock Absorbers

The shock absorbers help in maintaining the comfort level while you are driving. Providing the user with absolute control over the vehicle in rough road conditions also increases overall safety. Since we have already discussed a list of such shock absorbers, your selection process might have become easier. To further assist you by addressing any confusion, we are presenting this buying guide.

1. Shock Absorber Type

Shock absorbers are available in various types that are suitable for certain applications. They have different constructions and hence their working is different from each other. Some types of shock absorbers are discussed below:

2. Telescopic Shock Absorbers

This type is the most commonly used shock absorber. They consist of tubes arranged into each other like a telescope. To allow dampening of shocks, oil is used with a valve arrangement. The tubes compress leading to the compression of the oil through a small opening of the valves.

3. Strut Suspension

The strut is an integral part of a vehicle’s suspension system. It not only offers the shock-absorbing feature but also provides structural support to the whole setup and tires. The strut has a solid shaft that compresses the oil while retracting into the strut body. A spring is provided to add resistance to the shocks.

4. Coilover Shock Absorbers

The Coilover shock absorbers are a little bit similar to the struts. They have a piston and cylinder arrogant which is filled with gas or fluid medium. This medium is compressible and offers the dampening of the shocks. Furthermore, the spring is also attached to the cylinder body and piston which offers different riding heights and adjustable dampening.

5. Vehicle Compatibility

You don’t want to buy a shock absorber that won’t fit your vehicle’s chassis or suspension system. The specifications of a shock absorber help in checking its compatibility with your vehicle. Checking the riding height of the vehicle helps in selecting a unit with the right spring travel. The unit’s mounting specification must match that of the vehicle’s suspension mourning. The shock absorber must offer proper clearance between other parts of the vehicle while in motion, to avoid any wearing.

6. Driving Conditions

Every terrain exerts a different type of load on the ties and suspension system. Some shock absorbers are terrain specific. For off-roading, a heavy-duty shock absorber will be ideal. They offer a smooth dampening effect to adapt to the unevenness of the road.

For perfectly paved roads, the regular shock absorbers will perform well and save you money on buying a heavy-duty unit. These shock absorbers have more dampening to increase comfort. The race-spec shock absorbers are stiffer to offer great maneuverability to the race car on the tracks.

7. Material

The material of a shock absorber plays a vital role in its durability and functionality. When a vehicle drives through changing road terrain, the suspension system experiences tremendous loading shocks. The slightest creep in the material can cause suspension failure leading to hazards. The material is chosen by keeping its ultimate strength in mind.

Aluminum and steel are the common materials for shock absorbers. Steel is used due to its strength and cheaper pricing. But it is prone to corrosion and its heavy weight might not be suitable for some applications. Aluminum is corrosion-resistant and also has good strength, making it a good alternative to steel.

8. Loading Capacity

The loading capacity gives an idea of the maximum weight the shock absorber can endure. This helps in getting the desired performance from the suspension system. It also helps in avoiding the overloading of the suspension.

Certain techniques are introduced to increase the loading capacity of a shock absorber. Using dual sprigs of different stiffness helps in offering comfort and control over the vehicle. Using a dampener with these springs can further increase the loading capacity. The user must calculate the gross weight of a loaded vehicle to select the proper shock absorber and avoid overloading.

Frequently Asked Questions

1. Can a front shock absorber be used for rear mounting?

Ans: The loading condition on both the front and rear sides of a vehicle is different. The loading capacity might be the same sometimes but their performance is different. The user might feel uncomfortable due to the uneven dampening of the shock. Hence the front shock absorber is not suitable for rear use and vice versa.

2. Are shock absorbers free of maintenance?

Ans: Shock absorbers are not maintenance-free as they are made up of various mechanical parts that need periodic check-ups. Hence, shock absorbers have a set interval of maintenance. This includes changing the oil or gas, changing the rubber seals, and checking for any wear of the metallic parts.

3. How to check for shock absorber failure?

Ans: Various symptoms help in identifying a bad shock absorber. The user will experience uneven bouncing of the vehicle along with an increase in vibrations. A marginal change in the overall control can be detected. By externally checking for oil leaks, the user can get an idea about any external damage to the shock absorber.

4. What is the overall life of a shock absorber?

Ans: Every brand specifies the average life of its shock absorbers in kilometers before replacement. But the overall life also depends on the riding conditions, driving style, and other factors. This significantly increases or reduces the durability of the shock absorbers. The suspension system lasts longer on a peeved road compared to off-roading conditions.

Conclusion

The transition from a stiff suspension system to a comfortable one was achieved through various stages of development. The suspension system of the present is blessed with the option of customization as various alternatives are present in the market. The list of such alternatives was explained thoroughly along with their technical specifications. A buying guide and some FAQs were also discussed to assist your selection process. By keeping the overall discussion in mind, we have chosen our favorite options from the list.
