What is the main purpose of a performance valve spring?

Performance valve springs are designed to maintain consistent pressure on the valves, especially at higher engine speeds. This helps prevent valve float, which is when the valve doesn't close properly, leading to potential engine damage and reduced performance.

What does 'single spring' mean in this context?

A single spring design uses one coil spring per valve. This is often sufficient for many performance applications, offering a simpler and lighter valvetrain compared to dual or triple spring setups.

What is the Prop 65 warning about?

The Prop 65 warning indicates that this product contains chemicals known to the state of California to cause cancer or reproductive harm. It's a state-specific labeling requirement and does not necessarily mean the product is unsafe for its intended use.

About this part

Product Details

The NexTek Series single valve spring from Manley Performance is built with a specific spring rate designed to handle the demands of high-performance LS-series engines. This spring is a solid option when you're rebuilding the top end of your Chevy small-block or LS-based engine and need reliable valve control.

Manley uses a high-tensile wire for these springs, ensuring they can maintain consistent pressure across a wide range of RPMs. This helps prevent valve float, especially when you're pushing your engine harder. The single spring design is straightforward and effective for many performance applications where a dual spring setup isn't necessary.

When you're working on your engine, choosing components that are well-made and suited for performance is key. This Manley valve spring is a popular choice for builders looking for dependable valve control without overcomplicating their valvetrain.
