The 2 Most Common Types of Automotive Springs

Springs are one of the most ubiquitous types of parts in cars. But did you know that there are actually quite a few kinds of springs you’ll run across when working on a car? You’ll want to understand some of the basic differences even if you’re doing some simple repairs — and you’ll want to do quite a bit more research if you’re getting into a custom project. Here’s some information on the two most common types of automotive springs to get you started:

How Compression Springs Work in Cars

Compression springs are defined as such because they resist linear compressing forces. This is easiest to visualize in a straight coil spring with a consistent diameter; the energy is stored when the two ends are pushed toward each other. This is actually one of the most efficient energy storage methods available. These types of springs are used in order to operate valves within an engine, and proper spring calibration is vital to ensure that the spring keeps up with the engine’s speed.

How Torsion Springs Work in Cars

Torsion springs, on the other hand, store mechanical energy when they are twisted. They may look more like rods than the more iconic coil spring. Torsion springs are used for many purposes in cars (even door handles, sometimes), but are best known for being used in auto suspension and shock absorption systems, especially in heavier vehicles.

Choosing Among Automotive Springs Manufacturers

When you’re looking at automotive springs manufacturers, there are a few things you’ll want to look out for. First of all, you’ll need to figure out whether you simply need replacement springs or if you want custom automotive springs designed to improve performance in some way. Some spring manufacturers will also offer only larger batches of springs; that’s fine if you’re doing quite a bit of work, but may not be cost-effective if you’re restoring only a single car. No matter what project you’re taking on, it’s important you’re clear on the manufacturing standards upheld by the maker so you know you’re using springs that are strong enough for their intended purpose.
