.990 TI Valve Spring Retainers - 7 Degree

The .990 TI Valve Spring Retainers - 7 Degree from PAC RACING SPRINGS are precision-engineered components designed for high-performance engine builds where valve control and reliability are non-negotiable. These retainers are essential for any serious street or race engine modification, particularly when upgrading to aggressive valve spring packages that demand superior geometry and load stability.

Manufactured from titanium alloy, these .990-inch diameter retainers deliver a significant weight reduction compared to stock steel units, which directly translates to lower inertia and faster valve acceleration—critical for optimizing flow efficiency across the entire RPM band. The 7-degree valve angle geometry is precisely machined to maintain proper retainer-to-valve stem contact, preventing wear and ensuring consistent spring preload under sustained high-lift conditions.

These retainers are ideal for engine builders, professional mechanics, and dedicated enthusiasts tackling significant cylinder head modifications. Their design works in concert with performance valve springs to maintain optimal seating force, eliminating valve lash instability that can lead to bent pushrods, valve float, and damaged cylinder heads.
