Beehive shaped valve spring design allows a reduced retainer end mass for improved rpm potential. Every Engine Pro performance valve spring goes through a multiple shotpeening process for maximum durability and stress relief.

The chrome silicon vanadium nickel alloy valves spring goes through a "Heat Set" process and special heat treatment are used to extend spring life and minimise load loss. Ovate wire shape more evenly distributes mass throughout the wire cross section.
