What is the advantage of a beehive spring design?

Beehive valve springs are smaller in diameter at the top than traditional dual springs. This reduced mass at the retainer can help improve valve control, especially at higher engine speeds, and can also allow for the use of lighter retainers.

What does '7 Degree Pro' refer to on the retainers?

The '7 Degree Pro' refers to the angle of the retainer seat where it interfaces with the valve stem seal. This specific angle is designed to match certain valve guides and seals for optimal performance and sealing in HEMI applications.

Do these springs come with valve seals or locks?

This set includes the valve springs and the CNC steel retainers. Valve locks (keepers) and valve seals are typically sold separately and should be verified for compatibility with your specific engine build.

About this part

Product Details

Ferrea is well-known for making high-performance valvetrain components, and this set of Beehive Valve Springs with 7 Degree Pro CNC Steel Retainers is a prime example of their work for Chrysler and Dodge HEMI engines. If you're rebuilding the top end of your 5.7L or 6.1L HEMI, these springs are designed to handle the demands of performance camshafts and higher RPMs.

This set includes 16 springs and 16 retainers, all precisely machined. The beehive design helps reduce mass compared to traditional dual springs, which can improve valve control at higher engine speeds. The CNC-machined steel retainers are well-built and ensure a solid seat for the springs, contributing to consistent valve operation. This is a popular choice for enthusiasts looking to get more out of their HEMI engine.
