Coilovers vs Struts


Coilovers are a type of suspension system that combines a coil spring and a shock absorber into a single unit. Unlike traditional shocks and springs, which are separate components, coilovers integrate both functions into a compact and adjustable package. They are commonly used in high-performance vehicles and offer excellent versatility for different driving conditions.

How Do Coilovers Work?


The coil spring in a coilover supports the vehicle’s weight and absorbs bumps and road imperfections, while the shock absorber controls the spring’s oscillations, preventing excessive bouncing. The height of the vehicle can be adjusted through the threaded body of the coilover, allowing drivers to fine-tune the ride height and corner balance.

Advantages of Coilovers

Coilovers have several advantages, including their adjustability, enhanced handling capabilities, and improved stability during aggressive driving. They are popular among car enthusiasts who seek better performance and a more personalized driving experience.

Disadvantages of Coilovers

While coilovers offer numerous benefits, they may not be suitable for everyone. One of the primary drawbacks is their higher cost compared to traditional suspension setups. Additionally, the complexity of adjusting coilovers may require professional help, and improper setup can negatively affect the vehicle’s performance and comfort.

What Are Struts?

Struts, like coilovers, are a crucial component of a vehicle’s suspension system. They are designed to handle both the shock absorption and structural support functions, making them an integral part of the vehicle’s chassis. Struts are often found in front-wheel-drive vehicles and some rear-wheel-drive cars.

How Do Struts Work?

Struts operate similarly to coilovers in terms of shock absorption. They use a coil spring to support the vehicle’s weight, but instead of a separate shock absorber, the strut assembly itself acts as the shock absorber, it is important to know the difference between springs and coilover. This design simplifies the suspension system and can lead to a more compact and cost-effective solution.

Advantages of Struts

Struts offer a straightforward and space-efficient suspension design, making them a common choice for many vehicle manufacturers. They are generally less expensive than coilovers, and their simplicity makes them easier to maintain.

Disadvantages of Struts

While struts have their advantages, they may not provide the same level of performance and adjustability as coilovers. Their design limitations can restrict customization options for enthusiasts seeking specific handling characteristics.

Coilovers vs. Struts: A Detailed Comparison

Performance and Handling

The performance difference between coilovers and struts lies in their adjustability. Coilovers allow for precise tuning of the suspension to match different driving styles and road conditions, providing superior handling during aggressive driving or on the track. On the other hand, struts are generally more straightforward and may not offer the same level of performance tuning.

Adjustability and Customization

Coilovers shine when it comes to adjustability and customization. Drivers can modify the ride height, spring rates, and damping settings to tailor the suspension precisely to their preferences. Struts, while simple and effective, lack the same level of flexibility.

Comfort and Ride Quality

Struts often offer a more comfortable and smoother ride, especially for daily driving and regular road conditions. Coilovers can be adjusted for improved comfort, but improper setup might result in a stiffer and less comfortable ride.

Cost Considerations

Cost is a significant factor when comparing coilovers and struts. Coilovers tend to be more expensive due to their added features and adjustability, while struts offer a more budget-friendly option for those seeking a straightforward suspension solution.

Choosing the Right Suspension for Your Needs

Daily Driving and Comfort

If you primarily use your vehicle for daily commuting and seek a comfortable ride, struts might be the better option. They provide a balanced and smooth ride quality suitable for regular road conditions.

Performance and Track Use

For spirited driving and track use, coilovers are the preferred choice. Their adjustable settings and performance-oriented design can enhance cornering ability, reduce body roll, and provide better feedback to the driver.

Off-Road and Rally Applications

When venturing off-road or participating in rally events, coilovers with adjustable ride height and damping settings offer improved versatility, allowing drivers to adapt to different terrains and driving conditions.

Street Tuning and Lowering

Enthusiasts who enjoy street tuning and lowering their vehicles for an aggressive stance often opt for coilovers. The ability to fine-tune ride height and corner balance provides better control over the vehicle’s appearance and performance.

Installation and Maintenance

Installing Coilovers

Installing coilovers requires more technical expertise compared to struts. While some enthusiasts might perform the installation themselves, it’s essential to ensure proper setup and alignment for optimal performance and safety.

Installing Struts

Struts, due to their simpler design, are generally easier to install, making them a popular choice for DIY enthusiasts. However, professional installation is always recommended to ensure proper alignment and functionality.

Maintenance Tips for Coilovers

Regular maintenance is crucial for coilovers, especially considering their complexity. Periodic inspections, cleaning, and proper adjustments can help prolong their lifespan and maintain optimal performance.

Maintenance Tips for Struts

Struts are relatively low-maintenance components, but routine inspections and replacements are still necessary to ensure safe and reliable operation.


Choosing between coilovers and struts is a crucial decision that will impact your vehicle’s performance, comfort, and handling. Each option comes with its unique set of advantages and disadvantages, catering to different driving preferences and styles. If you seek a versatile, customizable, and performance-oriented suspension, coilovers might be the best choice. On the other hand, if comfort and simplicity are paramount, struts offer an excellent solution. Ultimately, the right suspension choice depends on your individual driving needs and preferences.
