Race Tech Progressively Wound Shock Spring

Race Tech HP Springs have a high stiffness-to-mass ratio. In other words, each spring is particularly light for its particular spring rate. This requires the finest materials and processing. Each spring is shot-peened and preset so it won’t sack out over time.
