What is the main benefit of using a titanium retainer?

Titanium retainers are chosen for their strength and light weight. This helps reduce the overall mass in the valve train, which can lead to improved engine response and better performance at higher RPMs.

What does the 7-degree angle refer to?

The 7-degree angle on the retainer is designed to match specific valve spring setups. It's important to ensure this angle is compatible with the valve springs you are using in your engine build.

Does this retainer come with valve springs or keepers?

This Ferrea part number E11025-1 is for a single titanium valve spring retainer only. Valve springs and keepers are sold separately and must be chosen to be compatible with this retainer and your engine build.
