NITRO BLACK BEEHIVE SPRINGS
Super Clean Chrome Silicon Vanadium Nickel Alloy
· Beehive shaped design allows a reduced retainer end mass for improved rpm potential
· Every spring goes through a multiple shot peening process to ensure maximum durability and stress relief
· "Heat Set" process and special heat treatment are used to extend spring life and minimize load loss
· Ovate wire shape more evenly distributes mass throughout the wire cross section

ENGINE PRO SUPER CLEAN STREET/RACE VALVE SPRINGS
Dual Valve Spring Assemblies
All Engine Pro valve springs are manufactured using the highest
· Every spring goes through a multiple shotpeening
quality chrome silicon or high tensile chrome silicon vanadium
process for maximum durability and stress relief
alloy materials. Our springs are inspected during the manufacturing
· "Heat Set" process and special heat treatment are used to
process to ensure consistent dimensions and overall quality.
