About this part

Product Details

This package includes sixteen (16) Manley Performance double valve spring retainers. These retainers are specifically made for 1.550 inch diameter valve springs and are designed to be +.100 inch over standard size. They are a well-built component for engine builds where valve spring control is critical.

Manley Performance uses titanium for these retainers, which offers a strong yet lightweight option for your engine's valvetrain. This material choice helps reduce overall valvetrain mass, which can lead to improved performance and durability. The +.100 inch over size is important for specific camshaft profiles or cylinder head porting that requires a slightly different spring installed height. Ensuring you have the correct installed height is key for proper valve spring function and longevity.

When rebuilding or modifying an engine, especially one where high RPMs or aggressive camshafts are involved, the quality of your valve spring retainers matters. These Manley retainers are a solid option for builders looking for reliable components for their performance engine.
