Ferrea Nissan NEO Double Spring 6 Deg Pro CNC Titanium Retainer - Set of 24

Crafted from aerospace-grade titanium, these Ferrea NEO retainers are CNC machined for precision. They are designed to work with double valve springs and feature a 6-degree angle, which is crucial for proper valve seating and sealing in high-performance Nissan engines. The titanium construction significantly reduces weight compared to steel retainers, which helps to decrease valve float at high RPMs and allows the valve train to operate more efficiently.

Ferrea is known for making well-built engine components, and this set of 24 retainers is no exception. The CNC machining ensures that each retainer is identical, providing consistent performance across all cylinders. This attention to detail is important for engine longevity and peak power output, especially when you're pushing your Nissan's engine to its limits. By reducing the mass at the top of the valve stem, these retainers contribute to improved engine response and reliability under demanding conditions.

This set includes 24 retainers, enough for a complete engine build on most common Nissan configurations. When installing these, ensure you follow the manufacturer's recommended valve spring seat pressures and installation procedures to get the most benefit from their advanced design. These retainers are a key component for anyone rebuilding or modifying a Nissan engine where performance and durability are top priorities.
