Coilover suspension systems are a game-changer for automotive enthusiasts who want to enhance both performance and ride comfort. Coilover suspension kits are a complete suspension system that replaces both the shock absorber and spring, offering a significant upgrade over traditional setups. At Coilovers, we recognize the importance of understanding how these systems work to maximize their benefits. In this text, we’ll investigate into the intricacies of coilover suspension, highlighting how its components function together, the advantages it offers, including the customizable settings of adjustable coilover kits such as ride height, damping, and rebound, and essential maintenance tips to keep your setup performing at its best.
Introduction to Coilover Suspension
Coilover suspension kits are a popular upgrade for drivers looking to transform their vehicle’s handling, ride quality, and overall performance. These complete suspension systems combine a shock absorber and coil spring into a single, integrated assembly, replacing the factory suspension components for a more advanced setup. One of the main attractions of coilover suspension kits is their adjustability—most kits feature adjustable dampers, allowing you to fine-tune your car’s suspension to match your personal preferences and driving conditions. Whether you want to adjust ride height for a more aggressive stance, set spring preload for optimal support, or dial in damping for improved handling, coilover suspension kits offer a high level of customization. This flexibility makes them a favorite among tuners and enthusiasts who demand both comfort and performance from their suspension systems.
Understanding Coilover Suspension Components
A coilover suspension integrates a coil spring and shock absorber into a single unified unit. Unlike traditional suspension systems where springs and shock absorbers function as separate components, coilovers combine these elements to provide enhanced control and flexibility. This integrated design allows for straightforward installation while delivering superior tunability compared to conventional systems. For Chevrolet vehicles, coilover suspension systems are a popular upgrade, often replacing or modifying traditional struts to deliver greater adjustability and improved handling performance. When installing coilovers on a Chevrolet, they typically replace the factory suspension components, also known as “stock” parts, to enhance ride quality and driving dynamics.
The main components of a coilover system include:
-
Coil spring (main spring and helper spring)
-
Shock absorber (damper)
-
Upper and lower mounts (the coilover unit is mounted to the vehicle's chassis or suspension arms)
-
Adjustment mechanisms
-
Bump stops
-
Bushings and collars
The Spring Mechanism
The coil spring serves multiple critical functions. It supports the vehicle’s weight, absorbs vertical road impacts, and mitigates body roll during cornering. The spring assembly typically consists of a stiff main spring that compresses the shock and maintains upward movement after impacts, which can improve performance during aggressive driving, plus a thinner helper spring that keeps the main spring engaged.
Spring performance can be tuned by adjusting the number of coils, wire thickness, coil shape, and end design. Coilover springs help reduce chassis bottoming out, control weight transfer when accelerating to enhance grip and stability, minimize squatting during acceleration, and reduce diving during deceleration.
The Shock Absorber Function
The shock absorber, also called a damper, controls suspension movement to prevent excessive bouncing. Inside the damper, a piston moves through oil in a sealed cylinder, with oil flowing through small holes to create hydraulic resistance that slows motion. Adjusting the damper's stiffness allows you to fine-tune ride comfort and handling—higher stiffness improves handling and grip, while lower stiffness increases comfort.
Coilovers feature two damper types:
-
Mono-tube: Single piston and rod assembly providing more sensitive response to small movements.
-
Twin-tube: Inner and outer cylinders with hydraulic reserve, offering increased suspension stroke and better ride quality.
Types of Coilover Suspension
There is a wide range of coilover suspension options available, each designed to meet different needs and driving styles. Manual lowering coilovers are ideal for those who want to lower their vehicle’s ride height and enhance its appearance, providing a simple way to achieve a custom look. For Chrysler vehicles, these setups are a popular choice for improving stance while maintaining everyday drivability. Drivers seeking more advanced performance can opt for coilovers with adjustable rebound and compression damping, allowing precise tuning of suspension response to road conditions and driving demands. High-performance coilovers are engineered for racing and track use, offering extensive adjustability and customization to maximize grip and control during aggressive driving. For added convenience, electronically adjustable coilovers make it easy for Chrysler owners to switch between comfort and performance settings at the touch of a button, adapting seamlessly to daily driving or spirited track sessions.
Adjustability Features of Coilovers
Ride Height Adjustment
Coilovers allow height adjustment through preload control on the spring. In addition to lowering, coilover suspension can also be raised to increase ground clearance when needed, thanks to the adjustable screw threads on the suspension strut. Standard coilovers use fixed lower mounts, while adjustable lower mounts provide greater range when lowering vehicle height. This adjustability directly affects vehicle handling and comfort.
Damping Control
Adjustable damping modifies hydraulic resistance by changing the size of slits within the coilover. This fine-tunes how quickly the suspension compresses and extends based on driving conditions, and allows you to adjust damper 'hardness' to tailor the suspension response to your driving preferences.
Damping adjustments fall into several categories:
-
Compression-only adjustment
-
Rebound-only adjustment
-
Combined rebound and compression
-
Independent high and low-speed adjustment.
Suspension Tuning
Suspension tuning is at the heart of what makes coilover suspension kits so appealing. With adjustable coilovers, drivers can fine-tune their suspension to achieve the perfect balance between ride quality and improved handling. By adjusting rebound and compression damping, you can tailor your car’s response to bumps, corners, and various road conditions, ensuring optimal performance and comfort. Many coilover suspension kits also allow you to change the spring rate, further customizing the suspension to your personal preferences and driving style. Proper suspension tuning can reduce body roll, enhance stability, and provide a more connected driving experience. Whether you’re looking to sharpen your car’s handling for the track or simply want a smoother ride for daily driving, the adjustability of coilovers puts you in control of your vehicle’s performance.
Benefits of Coilover Suspension Systems
Improved Handling and Performance
Coilovers reduce unsprung weight by combining components into a single unit, allowing suspension to react more quickly to bumps and maintain better tire contact. For example, during aggressive cornering or on a track, coilover suspension helps maintain optimal tire grip and stability, resulting in sharper handling and improved lap times. This integration enhances vehicle stability and cornering ability.
Adjustable damping optimizes weight transfer during acceleration, braking, and cornering, distributing weight more evenly and reducing body roll.
Customizability for Vehicle Needs
Coilovers provide superior customization compared to traditional systems, allowing drivers to adjust both ride height and damping settings for specific driving preferences. For the most part, drivers use their vehicles in normal conditions, but they can still benefit from the customization and adjustability that coilover suspension offers. This tunability suits both regular roads and track use.
