WOMBAT 4x4 PERFORMANCE TAPERED WIRE/PROGRESSIVE RATE COIL SPRING 

"The Intelligent Coil Spring" (by King Springs).

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.

 

The science behind designing a progressive rate coil is knowing over what suspension travel

and to what degree the spring rate will increase.

Progressive Rate Design Principles.

Remembering the principle, 'the less coils in a spring, the higher the spring rate'

as the spring compresses under load the gathered coils come into contact

and become inactive thus increasing the spring rate.

The point at which each coil comes into contact and the rate of increase

is the result of extensive research, development and testing

on advanced testing equipment.
