Ferrea Chevrolet LS1/LT1 Double Spring 7 Deg Pro CNC Titanium Retainer- Set of 16

This is a set of 16 Ferrea Chevrolet LS1/LT1 Double Valve Springs, designed for performance engine builds. These springs are crucial for controlling valve motion, especially in high-RPM applications where stock springs can struggle to keep up. They help ensure the valves close reliably, preventing potential piston-to-valve contact and maintaining engine integrity under stress.

Ferrea uses high-grade materials and advanced manufacturing for these springs. The set includes CNC-machined titanium retainers, which are significantly lighter than steel retainers. This weight reduction in the valvetrain means less mass is being accelerated and decelerated, allowing for higher engine speeds and improved valve control. The double spring design offers increased seat pressure and open pressure compared to single springs, providing more robust control over the valves, particularly with aggressive camshaft profiles. The 7-degree lock angle on the retainers ensures a secure fit with compatible valve locks.

This set is intended for builders looking to maximize the performance and reliability of their LS1 or LT1 engines. Proper installation is key, and it's recommended to consult your engine builder or a service manual for specific installation procedures, including spring height and any necessary valvetrain geometry checks. Ensure you have the correct valve locks that match the 7-degree angle of the included retainers for a secure and effective setup.
