KING SPRINGS TAPERED WIRE / PROGRESSIVE RATE COIL SPRING "The Intelligent Coil Spring"

There is no disputing the advantage of increasing the spring rate in a vehicle to improve vehicle stability and load carrying capacity, however, in many vehicles we are often confronted with three major considerations:

• Ride Comfort
• Shock Absorber Control
• Spring Entrapment

RIDE COMFORT is always a consideration. The spring rate must increase enough to give improvement without causing undue harshness.

SHOCK ABSORBER CONTROL - The shock absorber obviously plays a vital role in controlling a vehicle's stability. Excessive spring rate can often find shock absorbers struggling to control the vehicle (lack of rebound control).

SPRING ENTRAPMENT - When an increase in spring rate and decrease in vehicle ride height is required, spring entrapment can become a problem. Previously, the only solution being a compromise of minimal increase in spring rate and/or minimal decrease in vehicle ride height giving unsatisfactory results (suspension bottoming or not low enough).

Progressive rate springs are the ultimate in spring design. The principle is simple. The spring rate increases when you need it (cornering, load carrying etc.) and decreases it when you don't. The science behind designing a progressive rate coil is knowing over what suspension travel and to what degree the spring rate will increase. This varies greatly between vehicles. Referring to the above 3 conditions with King Springs Tapered Wire / Performance Progressive Rate Springs a substantial spring rate increase is achieved with minimal loss of ride comfort as the spring rate increases and decreases where necessary. As the spring de-rates (the spring rate decreases) the shock absorber no longer struggles for rebound control and gives improved vehicle stability.

With the King's Tapered Wire / Progressive Rate Coil Springs, spring entrapment problems are now often solved with substantial spring rate increases and ride height decreases available.
