Best Shock Absorber Buying Guide & FAQ

These 10 shock absorbers are the best of the bunch – whatever your vehicle, lifestyle, or budget, we’re confident there’s something on our list to meet your needs. To help you find the perfect shocks for you – and get the most out of them – we’ve put together this brief guide. Below, we run through how to spot a quality shock absorber, the different types available, and how to tell if yours should be replaced.

What to Look for When Buying a Shock Absorber

When it’s time to choose new shock absorbers for your vehicle, it’s a good idea to watch out for the following features:

  • Appropriate Type

First and foremost, be sure to select the appropriate type of shock absorber for your vehicle, and your needs. Many manufacturers produce components with a specific type of vehicle in mind, so be sure to carefully check that the shock you purchase is compatible with your car. We’ll talk about the types of shock you’ll have to choose from in more detail below.

  • Good Service Life

Whatever we buy, we all want to get our money’s worth, and selecting a shock absorber with a long service life is highly cost effective. It can be difficult to tell how long a shock will last through specifications alone, but checking out customer feedback can be a big help. Besides this, look out for relatively thick pistons, strong materials, and a well-protected shaft. Many shocks use a rubber boot to achieve this level of protection.

  • Smooth Operation

A shock absorber’s job is to bear the brunt of vibrations and bumps from the road, helping to ensure constant road contact, and a smooth ride. To make sure your potential shock is up to the task, look out for low friction all weather fluid, and self-lubrication.

  • Quality Materials

A component is only as good as the materials it’s made from, so be sure to check that your new shock absorbers have been built from high quality metals. You can expect most shocks to be made from strong and durable steel, which is often preserved through a chrome or zinc coating. Look out for these materials, and you can rest assured the shock was built to last.

Why You Should Change Your Shocks

Even if your vehicle’s original shocks are functional, you might want to upgrade them for a few reasons, including:

  • Upgrading your shocks makes for a smoother ride – great for long journeys
  • Changing shock absorbers can better equip your vehicle for off-road driving
  • Reliable shocks can improve your vehicle’s handling
  • Upgrading your shock absorbers is a cost effective way to improve performance
  • Some new shocks allow your vehicle to better tow trailers and carry heavy loads
  • High quality shock absorbers help protect your car from potholes
  • Some shock absorbers heighten your vehicle’s ride for improved visibility
  • Switching out shock absorbers can improve your vehicle’s appearance

Types of Shock Absorbers

Shock absorbers typically fall into one of the following categories:

  • Gas Shocks

The ‘gas’ in gas shocks refers to the inert nitrogen with which this type of shock absorber is filled. They’re ideal for smaller vehicles, as they’re tough enough to handle plenty of bouncing around – typical for many passenger cars. Most new cars are fitted with this type of shock: they’re affordable, versatile, and last for around 100,000 miles.

  • Heavy Duty Shocks

As the name implies, this type of shock absorber is designed for heavy duty use, such as towing, off-roading, and carrying heavy cargo. Most of the shocks on our list fall into this category. Heavy duty shocks typically feature a larger center shaft than their standard cousins, and deliver a stiffer overall ride – great for heavy loads and trucks, but not so good for sedans or coupes.

  • Automatic Level-Control Shocks

These sophisticated shocks feature an air pump which activates to even out the vehicle’s weight distribution automatically. This helps to ensure a smooth ride, even when you’re carrying unusual loads. Unsurprisingly, these shocks don’t come cheap, and they’re typically found on luxury vehicles only.

  • Air Shocks

Air shocks can also be used to achieve even weight distribution in your vehicle, but they must be adjusted manually. If you haul often and are familiar with the adjustment process, air shocks could be ideal, otherwise, they may be more hassle than they’re worth.

  • Overload Shocks

Sometimes called ‘coil-over shocks’, this type of shock absorber features a spring coil fitted around the shock cylinder. This type of shock is best for off-road vehicles, such as dune buggies.

Best Shock Absorber FAQ:

Q: When Should I Replace My Shock Absorbers?

This will depend upon the brand in question, so always check the manufacuter’s advice. As a rule of thumb, shock absorbers should be replaced (in pairs) roughly every 50,000 miles.

Q: How Can I Test for a Bad Shock Absorber?

If one or more of your vehicle’s shock absorbers are failing, you’ll usually notice the following symptoms:
Unusual vibrations while driving
Unpredictable handling when you brake
Increased stopping distance
Uneven tire tread wear
Fluid leaking from the shock
Cracks in the shock

Q: How Do I Change a Shock Absorber?

The installation process will vary depending on the type of shock you choose, and you vehicle. Generally, you can expect to work through the following steps:
On a level surface, jack up your vehicle using a designated jacking point
Remove the wheels, and locate the current shock absorbers – generally fixed in place with a vertical bolt
Spray the old shocks with metal cleaner – this will make them easier to remove
Remove the old shocks using a ratchet and socket to remove the shock tower bolts
Disconnect the shock from the vehicle’s suspension with a socket set or nut splitter
Remove the shock absorber all together by wiggling it off its bolts
Fit the new shock onto the suspension control arm
Screw the nuts tightly for a snug connection
Check the torque specs for your vehicle (listed in its service manual) to ensure everything is secure
