About this part

Product Details

This is a 16-piece set of Manley valve springs designed for the 1990-1999 Mitsubishi Eclipse, Eagle Talon, and Plymouth Laser models equipped with the 4G63 or 4G63T DOHC 16-valve engine. Valve springs are crucial for keeping your valvetrain in sync, ensuring that your valves close quickly and reliably after the camshaft lobe allows them to open. This set is a well-built replacement or upgrade for stock springs, helping to maintain proper valve control, especially at higher RPMs.

Manley Performance is known for making solid engine components, and this valve spring set is no exception. The springs have an installed height of 1.160 inches and a closed height of 0.870 inches, which are important measurements for ensuring proper valvetrain geometry and function. Using a quality spring like these helps prevent valve float, a condition where the valves don't close fast enough, which can lead to serious engine damage. This set is a popular choice for those rebuilding or modifying their 4G63 engine, aiming for improved reliability and performance.

When installing these valve springs, it's important to follow the manufacturer's recommended procedures to ensure correct setup and function. This set is designed to work with the factory retainers and valve seals, but always check the specific requirements for your engine build. Having the right valve springs is a key step in ensuring your engine performs as it should, especially if you're pushing the limits of the stock setup.
