What engine sizes do these Manley valve springs fit?

These valve springs are specifically designed for the 4G63 and 4G63T engines. This covers a range of Mitsubishi, Eagle, and Plymouth vehicles from the early 90s through the mid-2000s.

Do I need to buy anything else to install these valve springs?

This set includes all 16 valve springs required for your engine. However, depending on your specific build, you may also need new retainers, valve seals, and potentially other valvetrain components. Always refer to your vehicle's service manual or your performance build guide for a complete parts list.

What is the significance of the 1.100" / 0.775" specs?

The 1.100 inch measurement refers to the installed height of the spring, while 0.775 inches is the maximum valve lift the spring is designed to accommodate. These figures are crucial for ensuring proper valvetrain geometry and function with your chosen camshaft.
