Manley 23685L-16 Lightweight Super 7° Titanium Valve Spring Retainer 1.620" Double Spring 17 Gram

The Manley 23685L-16 Super 7° Titanium Valve Spring Retainer is a lightweight, high-performance component designed for serious racing and high-RPM applications. Engineered for 1.620" outside diameter double valve springs, this lightweight version features a 1.460" outer diameter, 1.175" inner diameter B dimension, and 0.840" inner diameter C dimension.

Key Features:

• Lightweight "L" suffix version is 3-4 grams lighter than the standard part number, optimizing valvetrain dynamics
• Manufactured from premium heat-treated titanium alloys to dramatically reduce valvetrain mass and improve valve control
• Manley's Super 7 Degree design is actually 8 degrees, with heat-treated titanium material for maximum strength
• Available with Manley's exclusive impingement surface enhancement process option, which provides a 20% improvement in resistance to abrasion and 30% improvement in fatigue strength
• CNC-machined accuracy and proprietary surface finishing ensure consistent fit and maximum durability
• Standard height design for proper valve spring installation

The Super 7° lock system maintains superior clamping properties while overcoming extrusion problems with increased lock thickness, making Manley's retainers the highest quality in the industry. These titanium retainers enable higher RPM potential and superior fatigue resistance under extreme racing conditions, making them ideal for drag racing, circle track, road racing, and high-performance street applications.
