HPA FTX 3.2L VR6 Valvetrain Upgrade

Ferrea valve springs are developed from high strength alloys, including premium grade chrome silicone steel These springs are manufactured with state-of-the-art equipment. Our springs are heat-treated and stress-relieved, which dramatically increases the spring's life. Strict quality control procedures and cycle testing ensures consistency from batch to batch. Ferrea valve springs provide the stability needed for high lift, high rpm racing engines, while minimizing the load loss for today's aggressive valvetrain combinations.

Ferrea offers some of the finest valves on the market. Their extensive R & D facility is constantly implementing new designs and processes, which continues to keep them in the forefront of engine valve technology. The valves then undergo an extensive heat treatment and stress-relieving process to ensure molecular integrity and prolong the valve's life. All of Ferrea special processes provide maximum performance and reliability, affording longer life in today's professional racing engines.

Ferrea Titanium Retainers Ferrea Spring Seat Locators are precision CNC machined and in most applications, required for certain Ferrea Valve Springs. These locators are stronger than factory to withstand the higher stress involved with stronger springs and high revving engines.

Ferrea Hydraulic Lifter Shims reduce the factory hydraulic lifter travel, providing a more solid valvetrain assembly for high performance racing engines.
