Selby steel valve retainers (race)


These Selby valve retainers are manufactured in house from EN24 T  this material is widely used for a component undergoing the stresses involved in high performance valve gear. The design incorporates a radius in every change of direction rather than a plain chamfer, a radius spreads the stresses and so lengthens the fatigue life of the component. It weighs in at only 14 grams or 1/2 ounce, it is possible to make them lighter but only by reducing the fatigue life of the retainer so we choose to keep the dimensions to a well proven design.
