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.
