What is the main benefit of using single valve springs?

Single valve springs are often used in performance applications to handle higher engine speeds and more aggressive camshafts. They help ensure the valves close reliably, preventing valve float which can lead to power loss and engine damage.

Do these valve springs come with retainers or other hardware?

This product listing is for the single valve springs only. Retainers, seals, and other valvetrain components are sold separately.

Are these springs suitable for a stock engine?

While these springs can be installed on a stock engine, they are primarily intended for modified engines or those being rebuilt for performance. They are designed to handle more stress than stock springs.

Product Details

What you get with this Brian Crower kit are single valve springs designed for the Mitsubishi 4B11T engine found in the Evo X, and also for the Hyundai G4KF engine in the Genesis Coupe. These springs are a key component for anyone looking to modify their engine's valvetrain for better performance or to handle increased engine speeds.

Brian Crower is known for making well-built engine components, and these valve springs are no exception. They are designed to handle the demands of higher RPMs and more aggressive camshaft profiles. This means they can help prevent valve float, which is when the valves don't close properly at high engine speeds, leading to a loss of power and potential engine damage. By using these single valve springs, you're ensuring your engine's valvetrain can keep up when you push it harder.

If you're rebuilding the top end of your Lancer or Genesis Coupe, or planning a turbo upgrade that will increase boost pressure, these valve springs are a solid option to consider. They are a direct replacement for the stock springs, making installation straightforward for a mechanic.
