Airflow Research 8505-16 Titanium Valve Spring Retainer Set 10-Degree 1.500

The Airflow Research 8505-16 is a precision-engineered titanium valve spring retainer set designed for high-performance engine applications. These retainers feature a 10-degree locking angle and are sized for 1.500-inch diameter valve springs, making them ideal for racing and performance engine builds.

Key Features:

• Premium titanium construction for exceptional strength-to-weight ratio
• 10-degree locking angle for secure valve lock engagement
• 1.500-inch diameter compatible with high-performance valve springs
• Reduced reciprocating mass for improved valve train stability at high RPM
• CNC-machined for precise tolerances and consistent fitment
• Corrosion-resistant titanium material for long-lasting durability

Titanium valve spring retainers are essential components for high-revving performance engines, offering significant weight savings over steel retainers while maintaining the structural integrity required for aggressive valve spring pressures. The 10-degree design provides a secure lock-to-retainer interface, reducing the risk of valve lock failure during extreme operating conditions.
