Manley 7 Degree 32pc Titanium Valve Spring Retainers (for 13089 or Factory Valve Lock)

Manley Performance is well-known for making strong internal engine components, and these 7 Degree Titanium Valve Spring Retainers are a prime example. If you're rebuilding the top end of your 1999-2001 or 2007-2008 Ford Mustang, these retainers are designed to work with either Manley's 13089 springs or your factory valve locks, offering a solid option for serious engine work.

Crafted from titanium, these retainers are significantly lighter than steel equivalents. This reduced mass at the valve train means less inertia, which can help the engine rev more freely and improve valve control at higher RPMs. The 7-degree angle is a specific design choice that matches the angle of many performance camshafts and valves, ensuring a secure and proper seating surface for the valve lock. This attention to detail is crucial for maintaining valve train stability, especially when you're pushing your engine hard.

This set includes 32 retainers, enough for a V8 engine. They are a direct fit for the specified Mustang models and the Ford GT. When undertaking a performance engine build, using well-made components like these Manley retainers is key to achieving reliable power and longevity.
