What are Coilovers Good For?

Coilovers are a popular aftermarket suspension modification for many car enthusiasts.

They are designed to replace the factory shocks and springs with a single unit that combines both functions.

Coilovers consist of a shock absorber and a coil spring wrapped around it. They are adjustable, which means that you can change the ride height of your vehicle by adjusting the spring preload or the shock absorber's length.

Coilovers can be used to improve the handling and performance of a vehicle.

They offer better control and stability, especially during cornering and high-speed driving. They also provide a more comfortable ride, even on rough roads.

Will Coilovers Void Warranty?

The answer is yes, in many cases, installing coilovers on your vehicle will void its warranty.

Most dealerships will void the warranty if you make any modifications related to a car's suspension or drive chain.

Moreso if the coilovers were not properly installed and something goes wrong with one of the suspension components.

If the coilover is proven to be the direct cause of any suspension problem, then the warranty will be void.

However, some big dealers are performance-oriented and may still cover a warranty depending on the car's condition.

In many cases, it will have no direct impact on the powertrain warranty. That's why it's important to ask your local car dealer first about their policies to know the risks of installing coilovers.

Magnus-Moss Warranty Act

Of course, dealers cannot simply deny you of warranty, especially if the problem is proven to be unrelated to the coilovers.

Certain laws in place protect consumers whose cars are still under warranty, but want to use aftermarket replacement parts on their vehicles.

According to the Magnuson-Moss Warranty Act, a manufacturer cannot void a vehicle's warranty simply because an aftermarket part was installed.

The manufacturer must prove that the aftermarket part caused the damage or failure of a covered component.

For instance, if you install coilovers and your engine fails, the manufacturer cannot automatically deny your warranty claim. They must prove that the coilovers caused the engine failure.

Manufacturer's Stance

Some manufacturers may have specific guidelines for modifying their vehicles, and if you don't follow these guidelines, your warranty may be voided.

Additionally, if the coilovers are not installed correctly or if they cause damage to other components, the manufacturer may deny your warranty claim.

Here's a very helpful video that gives you specific tips on which modifications you can make and not void the warranty.

How to Protect Your Warranty

Fortunately, there are ways to protect your warranty while enjoying the benefits of coilovers.

Research Warranty Coverage

One of the most important things you can do is to research your warranty coverage and understand what modifications are allowed.

To learn more about these guidelines, you can search for car warranty booklets and guidelines on specific car models.

You can also inquire directly with your local car dealerships or manufacturers.

Some warranties may expressly exclude modifications like coil overs, while others may allow certain modifications but not others.

If you're unsure, it's always best to consult your dealership or manufacturer for a clear answer.

Use High-quality Coilovers

Another way to protect your warranty is to choose high-quality coilovers from a reputable manufacturer.

Cheap or poorly made coil overs can damage your vehicle, and the warranty may not cover the damage.

By choosing a trusted brand with a good reputation, you can ensure that your coil overs are safe and reliable.

Keep All Coilover Documentation

It's also a good idea to keep all documentation of your coilovers, including receipts, installation instructions, and any warranties or guarantees.

This documentation can help prove that the coilovers were installed correctly and are covered under warranty if any issues arise.

Work with Your Dealer

Finally, if you experience any issues with your vehicle, it's essential to work with your dealership or manufacturer to resolve the issue.

If the issue is related to the coil overs, they may ask you to remove them before they can diagnose and repair the problem.

It is important to note that even if a dealership denies a warranty claim due to the installation of coilovers, the rest of the vehicle's warranty remains intact.

For example, if a vehicle owner installs coilovers and then experiences a problem with their transmission, the dealership cannot deny the transmission warranty claim simply because coilovers were installed.

Talk to Your Dealer Before Making any Modifications

Coilovers themselves may not necessarily void your warranty. However, any modifications made to your vehicle can potentially affect your coverage.

To ensure that you don't run into any issues, it's always a good idea to consult with your dealership or manufacturer before making any modifications.

They can provide guidance on which upgrades are within the guidelines set forth by the manufacturer and won't affect your warranty coverage.

So make those upgrades, but do it wisely and with caution. Happy driving!
