    The Overwhelming Choice of Racers!

    K-Motion Valve Springs deliver the high quality and superior dependability required to meet their performance requirements. K-Motion starts with the highest quality wire available. All alloys used are manufactured and inspected to the highest industry standards. Quality wire is the first essential step in manufacturing springs designed for extreme, high, aggressive cam lifts and ramp speeds.

    Metallurgists measure a material's resistance to failure with fracture toughness. This, combined with the material's strength, determines 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 proper material is selected. After coiling, springs receive a variety of carefully controlled heat treatment and surface finishing processes. The intent is to reduce load loss and increase spring life. Each spring is visually inspected for surface imperfections, which could lead to early breakage, and dampers are radius ground and depointed for longer spring life.

    Each valve spring assembly is cold pressed with as much as 2500 pounds of pressure, based on application. A pink stripe is added for identification, and then each spring is individually pressure checked & boxed with no more than 5 pounds variation per box. From design to manufacturing to load matching spring sets, every effort is made to provide the very best valve springs.

    Hi, I just read in a chat room that these springs will drop right into a set of e-street heads and allow for hyd. Roller cam, higher lift and rpm, is that true? I have 1.5 rockers sum-g6905 for the build and was hoping to run a cam with .520 to .540 lift.

    Yes, these should work in that application as long as the installed height is set correctly.
