Product Details

This set includes 24 Ferrea Pro CNC Titanium Retainers, specifically made for Nissan TB48DE engines. These retainers work with double valve springs and feature a 6-degree lock angle, designed to handle the demands of high-performance engine builds. They are crafted from titanium, a material chosen for its strength and light weight, which helps reduce valvetrain stress.

Ferrea is known for making well-built valvetrain components, and these retainers are no exception. The CNC machining ensures precise dimensions, which is critical for proper valve sealing and consistent spring operation. By using titanium, Ferrea helps to lower the overall mass in the valvetrain. This can lead to improved engine response and durability, especially at higher RPMs where forces are significantly increased. The 6-degree lock angle provides a secure fit for the valve springs, preventing any unwanted movement or slippage under stress.

When rebuilding or upgrading the top end of your Nissan TB48DE, using high-quality components like these titanium retainers is essential for achieving reliable performance. They are designed to work with compatible double valve springs and the specific valve stem size for your engine. Ensure you have the correct double valve springs and keepers to pair with these retainers for a complete and effective valvetrain setup.
