Manley Valve Spring, SPRING-1.437 DOUBLE

These Manley Performance double valve springs are built with a specific spring rate and seat pressure in mind, crucial for keeping your engine's valvetrain in sync during high-RPM operation. They are constructed from a high-tensile steel wire, a well-built material chosen for its ability to withstand the repeated stress and heat generated within the engine's combustion chamber. This makes them a solid option for anyone rebuilding or upgrading their engine's top end, especially when aiming for improved performance and reliability under demanding conditions.

The double spring design offers increased stability and control over the valves, helping to prevent valve float at higher engine speeds. This design is particularly beneficial in performance applications where stock springs might not be robust enough to handle the increased forces. Manley has a reputation for producing well-made engine components, and these springs are no exception, offering a dependable solution for enthusiasts looking to ensure their engine performs as intended.
