Thicker Coil Springs: Are They Better?

Coil springs play a crucial role in a vehicle’s suspension system. They are responsible for absorbing the shocks and vibrations generated by uneven road surfaces and providing a smooth ride. Choosing the right coil spring ensures optimal driving performance, handling, and safety.

One common question car enthusiasts often ask is whether thicker coil springs are better than thinner ones. In this article, we will delve deeper into this topic and provide you with all the necessary information to make an informed decision.

Explanation of the Topic

Coil springs are mechanical devices that store compressed energy and release it when expanded. They consist of tightly wound steel wire wrapped around an axis or core.

When subjected to weight or pressure, they compress, storing potential energy that can be released when the force is removed. Depending on their intended use, coil springs come in different shapes, sizes, materials, and thicknesses.

Brief Overview of Coil Springs

There are three main types of coil springs: compression, torsion, and extension. Compression springs are the most common type used in vehicles’ suspension systems as they absorb vertical forces caused by bumps or dips in the road surface. Torsion Springs work similarly but absorb rotational forces like those generated during cornering or steering maneuvers while Extension Springs extend under axial loads like those from a trailer hitch.

Importance of Choosing the Right Coil Spring

Choosing the right coil spring for your vehicle is essential for several reasons. First and foremost, it affects how your car handles on different terrains such as highways or off-road conditions; if you choose too soft a spring rate relative to your vehicle’s weight or intended use cases (like towing), it will lead to excessive body roll during hard cornering that could cause accidents.

On the other hand, if you choose too stiff a spring rate, it may lead to a bumpy and uncomfortable ride. Choosing the right coil spring can also help extend your vehicle’s lifespan by reducing wear and tear on parts that would otherwise be subjected to excessive stress.

Understanding Coil Springs

Coil springs are a crucial component of a vehicle’s suspension system. They are designed to absorb shock and maintain the vehicle’s ride height.

A coil spring consists of a metal wire coiled in a helical shape. When force is applied, the spring compresses or extends, depending on the type of spring, and then returns to its original position.

Definition and function of coil springs

Coil springs are used to support the weight of a vehicle and absorb shocks caused by uneven terrain or bumps on the road. They work in conjunction with other suspension components such as shocks, struts, and sway bars to provide a smooth ride and stable handling.

Types of coil springs

There are three main types of coil springs: compression, torsion, and extension.

Compression Springs

Compression springs are the most common type of coil spring. They compress when force is applied to them, such as when a vehicle hits a bump or pothole in the road.

They return to their original position once the force is removed. Compression springs come in various shapes and sizes depending on their intended use.

Torsion Springs

Torsion Springs work by twisting around an axis rather than compressing or extending like other coil springs. They store energy when twisted and release it when it unwinds back to its original position. Torsion Springs are commonly used in vehicles with independent rear suspensions.

Extension Springs

Extension Springs operate by extending under tension when force is applied to them. They return to their original length once the force is removed. Extension Springs are often used in front suspensions because they have higher load capacities than compression springs.

Understanding different types of coil sprigs can help you choose the right kind for your vehicle. Compression springs are common and versatile, torsion springs are ideal for rear independent suspensions, and extension springs have a higher load capacity for front suspensions.

Advantages and Disadvantages of Thicker Coil Springs

Advantages

Increased durability and longevity: One major advantage of thicker coil springs is that they tend to last longer than thinner ones. This is because they are made with more material, which makes them stronger and less prone to bending or breaking.

As a result, vehicles equipped with thicker coil springs can typically withstand heavier loads and maintain their ride height for longer periods of time without sagging. Better handling and stability: Another advantage of thicker coil springs is that they improve handling and stability on the road.

This is because they provide more resistance to weight transfer during cornering, braking, and acceleration. As a result, vehicles equipped with thicker coil springs tend to corner flatter, have less body roll, and feel more planted overall.

Enhanced performance in rough terrain: Thicker coil springs can also enhance performance by providing better ground clearance, shock absorption, and suspension travel. As a result, vehicles equipped with thicker coil springs can better handle off-road obstacles such as rocks or tree stumps without sustaining damage or getting stuck.

Disadvantages

Less comfortable ride quality: One major disadvantage of thicker coil springs is that they provide a less comfortable ride quality than thinner ones. This is because thicker coils are stiffer than thinner ones, so they don’t compress as easily when encountering bumps or imperfections on the road surface. As a result, vehicles equipped with thick coils may transmit more vibrations or harshness through the chassis.

Higher cost compared to thinner springs: Another disadvantage of thicker coil springs is that they typically come at a higher cost than thinner ones. This is because the manufacturing process requires more material and time-consuming work to produce, which increases the overall cost of the spring.

As a result, vehicle owners may need to spend more money upfront to equip their vehicles with thicker coil springs. However, this cost may be worth it for those prioritizing performance and durability over comfort and cost.

How to Choose the Right Coil Spring for Your Vehicle

Choosing the right coil spring for your vehicle is crucial to improve its performance and handling. You need to consider various factors when making this choice, such as the vehicle weight, ride height desired, and terrain conditions. This section will discuss these factors in detail and provide guidelines for selecting the right thickness.

Factors to Consider When Choosing a Coil Spring

Vehicle Weight: The weight of your vehicle is one of the most important factors to consider when choosing a coil spring. A heavier car will require a thicker coil spring than a lighter one.

This is because thicker springs can support more weight and provide better stability. Ride Height Desired: Another factor to consider is the ride height that you want for your vehicle.

You should go for thinner coil springs if you want a lower ride height. Thicker springs will raise your car’s ride height.

Terrain Conditions: The terrain you will be driving on is also important in choosing the right coil spring. If you frequently drive on rough terrain or off-road, thicker springs are ideal as they can absorb shocks better than thinner ones.

Guidelines for Selecting the Right Thickness

You must know basic guidelines to select the right thickness for your coil spring. Typically, thicker springs have more coils and are made from stronger materials than thinner ones.

Suppose you have a heavy vehicle or frequently drive on rough terrain. In that case, it’s recommended that you choose thicker springs with more coils made from high-quality materials like chrome vanadium steel or silicon steel. Thinner springs may be good enough for lighter vehicles or cars used mainly on smoother roads with occasional bumps.

However, medium-thickness springs can be a good choice for improved handling performance, even in these conditions. When choosing the right coil spring for your vehicle, you need to consider various factors, such as the weight of your car, the desired ride height, and terrain conditions.

Additionally, you must know guidelines for selecting the right thickness based on these factors. Taking time to make these considerations will help you find a coil spring that improves your car’s handling and performance.

Maintenance Tips for Coil Springs

Coil springs are an essential component of your vehicle’s suspension system. You should follow some maintenance tips to ensure their longevity and continued performance. Here are some essential maintenance tips for coil springs to help you keep them in good shape.
