Progressive Rate Springs

Stanley Spring produces a progressive rate spring that allows a single spring to exhibit multiple rates. They are generally classified into two types, one a constantly increasing rate spring and the other a dual-rate spring with two linear rates connected. Most often used in the automotive industry, for high-performance driving, they offer great ride quality and high end handling due to the roll control offered by the springs.

Why are progressive rate springs “geared” towards the automotive industry?

Rider comfort!

The variable spring rate in progressive rate springs can react in different ways, depending on the type of demand being made. Progressive-rate springs, as they are compressed, become rigid quicker. As a rider in a car, this advantage is preferred as the vehicle, with a suspension firm enough to handle big hits, easily withstands small bumps, making for a more enjoyable overall ride.

Using progressive rate springs offered by Stanley Spring, it’s possible to have a suspension that makes cars:

  • Handle better during curves and turns
  • Comfortably absorb small bumps
  • Comfortably drive while going straight

Using a progressive rate spring allows vehicle manufacturers to produce cars that handle extremely well while also providing a comfortable driving experience. As a driver, you’ll be thankful for progressive rate springs when turning a corner, as the increased load on a progressive spring is what causes the car to lower as the suspension is compressed. When driving in a relatively straight line, stiffer rate from the progressive rate spring gives you the feeling of complete stability.

Stanley Spring is proud to work with the automotive industry, providing quality progressive spring rates that lead to vehicle handling and comfort.

Thank you all for the great response, especially you Leonel, I appreciate the extra you put into this. If you hadn’t done what you did we would have closed a full production line and sent home a bunch of people.
