K-Motion Valve Springs are the choice of winning racers. They know that K-Motion Valve Springs deliver the high quality and superior dependability required to meet their performance requirements. Whether you run on the drag strip, circle track, off-road or on the water, K-Motion Valve Springs can offer you the same performance to deliver you to the Winner's Circle, too.

K-Motion Valve Springs start with the highest quality wire available.  All four alloys used are manufactured and inspected to the highest industry standards.  Quality of the wire is the first essential step in manufacturing springs designed for extreme, high and aggressive cam lifts and ramp speeds.

Metallurgists measure a material's resistance to failure with fracture toughness.  This, combined with the material's strength, determine whether or not a material is a suitable choice for a specific application.  This is why K-Motion Valve Springs utilize four different alloys.  For each application, only the right material is selected.

After coiling the springs receive a variety of carefully controlled heat treatment and surface finishing processes.  All of these are intended to reduce load loss and increase spring life.  Each spring is then visually inspected for surface imperfections which could lead to early breakage.  The dampers are radius ground and de-pointed for longer spring life. 

Each K-Motion Valve Spring is then cold-pressed with as much as 2500 pounds of pressure, depending on the application.  A pink stripe is added for identification, then each spring is individually pressure checked and boxed with no more than five pounds variation per box.

From design to manufacturing to load-matching spring sets, every effort is made to provide you the very best valve springs available.  When you need valve springs, demand the very best...  K-Motion Valve Springs!
