ENGINE PRO Super Clean
Street/Race Valve Springs

Dual Valve Spring Assemblies All Engine Pro valve springs are manufactured using the highest quality chrome silicon or high tensile chrome silicon vanadium alloy materials. Our springs are inspected during the manufacturing process to ensure consistent dimensions and overall quality.

• Every spring goes through a multiple shotpeening
process for maximum durability and stress relief
• “Heat Set” process and special heat treatment are used to
extend spring life and minimize load loss

DUAL DRAG RACE VALVE SPRINGS

These springs feature a 15-30% reduction in physical mass! This coupled with a natural frequency increase of 20% means that your engine will rev higher, faster and last longer with more aggressive valve motion. Get the performance of Titanium with improved life and cost of steel directly from the spring manufacturer.

PAC Racing Springs has brought the latest technology to the Drag Racing Market. Traditional springs were made with higher load and rates without concern of spring mass and frequency. PAC Racing Springs has taken years of research and coupled that with exotic new heat treatment methods | to produce the next generation drag race springs.
