10 Deg Titanium Retainer

The 10 Deg Titanium Retainer by MANLEY is a precision valve spring retainer engineered for high-performance and competition engine builds. Designed to secure dual valve springs with exceptional reliability, this component is essential for serious enthusiasts and professional engine builders who demand lightweight construction without sacrificing strength. The 10-degree geometry optimizes valve train geometry and promotes consistent spring pressure across the valve lift cycle.

Manufactured from premium titanium, this retainer offers a significant weight reduction compared to traditional steel alternatives, directly improving valve train responsiveness and reducing inertia-related stress. The 1.175-inch inner diameter and dual OD steps (0.765 inches) provide a stable platform for dual spring configurations common in performance engines requiring sustained high RPM operation. Titanium's superior strength-to-weight ratio and resistance to fatigue make these retainers ideal for applications involving aggressive valve timing, high spring pressures, and extended engine cycles where material durability is non-negotiable.

This set of 16 retainers suits 8-cylinder engines or mixed applications requiring multiple replacement units. The 10-degree angle design is compatible with dual spring assemblies at 1.625 inches, making it suitable for modern LS, Gen III small-block, and comparable contemporary engine platforms. Professional engine builders and performance shops standardize on MANLEY titanium retainers for their proven track record in both street and competition environments. Proper installation requires precise valve seat concentricity and compatible spring pressures to maximize the benefits of this premium component.
