Manley Valve Spring, SPRING-1.250 SINGLE

This Manley Performance single valve spring is constructed from high-tensile wire, a strong material chosen for its ability to withstand the repeated stress of opening and closing valves. It's designed to work with Manley's own retainers and seats, ensuring a matched set for optimal performance. When you're building or rebuilding an engine, especially one that will see higher RPMs or more aggressive camshaft profiles, the valve springs are critical. They need to be strong enough to close the valve quickly and reliably, preventing valve float which can lead to serious engine damage. This spring is a well-built component for those looking to ensure their valvetrain can keep up with their engine's demands.

The 1.250-inch outer diameter is a common size that fits many performance cylinder heads. While it's a single spring design, it's intended for applications where a dual or triple spring setup isn't necessary, simplifying installation and reducing mass. It's important to pair these springs with the correct retainers and valve seals to achieve the intended performance and durability. If you're working on a performance build and need reliable valvetrain components, Manley has a solid reputation for making parts that hold up.
