• Enhanced resistance to coil bind and spring fatigue for extended service life
• Improves RPM capability and throttle response by reducing valvetrain inertia
• Compatible with stock and aftermarket valve train components
• Ideal for street performance, track use, and engine builds requiring reliable valve control

Construction & Design:

The springs feature a beehive shape, which tapers the coils to reduce weight while maintaining the necessary spring force. This design minimizes harmonic vibrations and valve float at high RPMs. The retainers are crafted from aerospace-grade titanium using CNC machining, ensuring precise tolerances and exceptional strength-to-weight ratio. Titanium retainers significantly reduce the rotating mass on the valve train, contributing to quicker engine response and improved durability under high-stress conditions.

Ferrea’s meticulous engineering ensures that each spring and retainer meets stringent quality standards, providing consistent performance and reliability for demanding Chrysler and Dodge HEMI applications.

Installation & Fitment:

This spring and retainer set is designed as a direct fit for most Chrysler and Dodge HEMI 5.7L and 6.1L engines, requiring no modifications for proper installation. Installation should be performed by a qualified technician or experienced enthusiast with the appropriate tools to safely compress valve springs and install retainers. Proper installation ensures optimal spring pressure and valve train function, contributing to engine longevity and performance.
