Why are these K-Motion valve springs the choice of so many winning Circle Track and drag racers? K-Motion springs are coiled from the finest chrome silicon or H-11 tool steel and then heat-treated and/or stress-relieved to the correct Rockwell hardness for each application. The springs are then visually checked for tool marks or pits, and dampers are radius-ground and de-pointed for longer life. Each spring is pressure-checked and boxed with no more than 5 lbs. of variation per box.
