Description

Crafted from titanium, this Manley Performance valve spring retainer is designed to reduce mass at the valve train. Titanium is notably lighter than steel, which helps to decrease the overall reciprocating weight in your engine. This reduction in weight can lead to improved valve control and potentially allow the engine to rev more freely. This retainer is specifically made for double valve springs, meaning it has the proper dimensions and locking grooves to securely hold a dual spring setup. The 1.550 inch diameter is a common size for many performance applications, and the double spring design is often chosen for its ability to control valve float at higher RPMs. By using a well-built titanium retainer, you're investing in a component that can handle the stresses of a performance engine while contributing to a more responsive valvetrain. When rebuilding or upgrading your engine's top end, components like these retainers play a crucial role in overall reliability and performance. Ensure you are using the correct spring and retainer combination for your specific camshaft and cylinder head setup to achieve the best results.
