Spotlight on Performance: Our Automotive Spring Applications
Automotive Springs are employed across hundreds of equipment systems and mechanisms. They are found in critical safety systems within automotive systems, such as engine clutches and transmission systems. Large compression springs are the primary component in many vehicle suspension systems that absorb dynamic forces from the wheels at the wheels and ensure passenger comfort.
Most importantly, engine valve compression springs ensure efficient fuel combustion thousands of times per minute of engineer operation. As such, they must perform under high temperatures and dynamic mechanical loading.
Automotive springs are also used inside the cabins of many automobiles, integrated into door latches and seat adjustment mechanisms.
What We Offer
Reliable Manufacturing Services
Century Spring offers automotive springs that qualify for complete Production Part Approval Process (PPAP) submission level classifications 1-5. The PPAP is a standardized manufacturing and procurement procedure used in the automotive and aerospace industries that shows that suppliers can consistently manufacture parts that comply with all customer design and quality specifications.
For example, submission Level 3 is most commonly specified for automotive springs. It provides the purchaser with a Part Submission Warrant (PSW), product samples, and a complete set of supporting data as required by the PPAP standard.
We have dedicated, high-speed machines that can scale spring production to the large product volumes typically required for automotive part production. We also offer in-house design for manufacturability (DFM) expertise to produce automotive springs that meet the most rigorous design and part tolerance requirements.
We offer cutting-edge computational equipment simulation and testing techniques, such as CNC compression self-monitoring and coiling machinery. These capabilities enable us to deliver durable, reliable products across many custom sizes and styles. Our manufacturing services also include complete prototyping and tooling assistance.
Our team will work directly with you to create, refine, and optimize spring designs to fit specific tolerance, performance, and use case conditions. We are ready to partner with you to solve your most pressing automotive spring design challenges.
Quality Materials
Carbon steel is the most commonly specified spring material for a wide range of automotive applications. Its elasticity, durability, and strength make it an economical choice for many automotive components. Available carbon steel alloys range from low to high, as defined by the carbon content.
Stock stainless steel automotive springs in 302/304 or 316 may also be specified for automotive applications requiring additional corrosion resistance.
We offer a wide selection of Beryllium Copper (BeCu) springs for automotive applications that require corrosion resistance, high strength, and electrical conductivity, such as electromechanical applications. These springs are also highly weldable and machineable, making them easily integrated into automotive assemblies.
Furthermore, Century Spring is committed to continuously testing new metals and secondary processing techniques to ensure we can always offer superior metallurgical capabilities and unmatched expertise with reliable, high-quality spring materials.

FAQs About Automotive Springs
What design factors should I consider when choosing a spring for an automotive application?
When choosing an automotive spring, you should first consider the force your spring needs to withstand and the allowable deflection of the spring you can tolerate within your application. This will allow you to calculate the spring's approximate spring rate and show you the approximate size of the spring your application requires.
Next, consider how the spring will be integrated into your assembly and the feasible end configurations for your application.
You should then consider environmental factors in your application and whether you need a stainless steel spring or a spring with additional surface treatments.
With these design factors as a starting point, you are ready to browse our spring catalog to find a spring that fits your automotive application.
What spring material do I need for my automotive application?
Automotive springs are typically fabricated from carbon steel or stainless steel, depending on the corrosion resistance needed for the specific automotive application. Beryllium Coopper (BeCu) is typically used as a spring material for high-performance automotive applications requiring electrical conductivity.
However, we offer a huge selection of in-stock springs suitable for any automotive applications from various materials such as Music Wire, Phosphor Bronze, and Oil Tempered.
