Valve Springs

Valve springs are among the most overworked and overstressed parts in your engine; yet, they are often the most overlooked components, too. Harmonics or high frequency fatigue is present in all racing engines and will usually destroy the valvetrain if not controlled. Properly designed valve springs will control the dominant harmonics, provide the needed stability, and reduce valvetrain component wear. We design valve springs for all forms of applications as well as springs in fuel injectors, latch mechanisms for valvetrain components, springs in torque converters, and clutch assemblies.

Design and Engineering of Valve Springs

Yisen’s engineers are fully experienced in product design, spring design analysis, dynamic simulation, and the application of advanced technology to produce innovation. We use a variety of software for spring design, modeling and assembly, and FEA to optimize performance. The latest improvements are on: advanced high tensile materials, nitriding and piece hardening, ovate and multi-arc wire sections, Beehive spring configuration, and advanced surface-finishing processes.

Our valve springs are computer designed to ensure that wire stress levels do not overpass the limits of stress defined in the diagrams of fatigue. We also utilize computer software that allows us to ensure that the harmonics are under control. This combined with our high quality steel alloy enables Yisen valve springs to be more durable in extreme conditions, giving your performance racing engine a serious competitive advantage in both performance and durability.

Summit Racing has single, dual, triple, beehive, and conical valve springs to meet your engine’s demands—no matter how high the rpm or lift!

1. What you need to do is sending us your design drawing, samples or design concept draft, after that we will assess your products and budget unit price for you.
2. We’ll communicate with you again about if there is a need for sample making after your approval.
3. Production time of samples: 3 days for simple samples and 7 to 10 days for complicated samples which need mold open.
4. For customers of first cooperation, we can make a proof for free to show our capacity and high efficiency service to you. As for particularly complicated samples, we will communicate with you separately.
5. Mass production delivery: usually delivery time is 10-15 days, but we can try 7-10 days if it is a rush order. It depends on production plan if it’s a sizable order.
6. Packaging: as to complicated products, we can special design based on your packing requirement.
7. Our freight advantage: a) If you are worrying about freight trouble because of your small quantity goods, it will be the best choice to use express. We will offer you the cheaper express price than the official UPS or DHL; for example, 100kg goods only need 6usd/kg and 50kg goods only 7usd/kg. If you just place an order for 1000pcs, you only need to pay very little express charges and gain the fastest delivery.b) If you place a large order, we will help you ship goods by sea, and we are very experienced to handle with it, we can organize all kinds of goods a whole container and recommend best vessels agent for you.
