K-Motion is the overwhelming 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 Winners 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 wire is the first essential step in manufacturing springs designed for extreme, high, aggressive cam lifts and ram 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 depointed for longer spring life. Each K-Motion Valve Spring assembly is then cold pressed with as much as 2500 pounds of pressure, depending on the application. A pink stripe is added for identification, and 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.

First the coil bind height of the spring you are going to use. Second the valve lift with the current camshaft and rocker arm combination. To these figures, add coil bind clearance. We strongly recommend that a minimum of.060 be used for this figure. To illustrate this method of determining the correct minimum installed height, see the example below.

Note that this is a minimum figure. Operating with a shorter installed height will severely shorten the life of the springs and may lead to breakage of the springs and related valve train components.
