What is the primary function of these valve springs?

These valve springs are designed to close the engine's valves after they have been opened by the camshaft. In high-performance applications, they ensure precise valve timing and prevent valve float, especially at high engine speeds.

What makes this a double spring setup?

A double spring setup uses two concentric springs working together. This design provides increased spring force and greater stability for the valve train, which is beneficial for handling aggressive camshafts and preventing valve float.

Are any other components needed for installation?

Yes, typically you will need compatible valve retainers, valve seals, and a suitable valve spring compressor tool specific to your engine. Always consult the manufacturer's installation guide for a complete list of required parts and tools.

About this part

Product Details

If you're rebuilding the top end of a high-performance engine, getting the right valve springs is crucial for reliable operation. These Manley valve springs are designed to handle the demands of aggressive camshaft profiles and higher RPMs, ensuring your valves open and close precisely when they should. They are a key component in maintaining engine health and performance under stress.

Manley Performance has a solid reputation for making well-built engine components, and these springs are no exception. They are constructed from high-tensile spring wire, which is heat-treated and stress-relieved to provide consistent pressure and durability. This means they can withstand the repeated cycles of opening and closing without losing their tension or breaking down over time. The springs are designed as a double spring setup, offering increased stability and control for the valve train, especially when paired with aggressive camshafts. This setup helps prevent valve float, a condition where the valve train can't keep up with the camshaft's speed, leading to poor performance and potential engine damage.

When installing these springs, it's important to ensure you have the correct spring compressor tool for your specific engine application, as well as the appropriate retainers and valve seals. Proper installation is key to achieving the performance and longevity Manley intends for these components. Always refer to the manufacturer's detailed installation instructions for your specific engine build to confirm all specifications and procedures.
