Are OME coils progressive?

Just currious to know if OME front coils (880, 881 & 882) are progressive? Of all the reading about these, I've never come accross the answer. :confused:

Not by definition. Of course spring rate is not linear anyway so as the spring compresses it takes increasingly more force to continue the compression.

As long as the additional force required is directly proportional to the deflection, that is linear. F=kx. Spring rate k is constant.

In a progressive spring, the rate is a function of the deflection, say F=(k+.1x)x. As the deflection increases, the spring rate increases.

Of course, this is all in theory. :)
You are correct on the constant
Highlighted is where reality of suspension geometry trumps theory. The spring rate is constant, but the force required goes up due to dynamic angles. Static angles would be ideal in theory but difficult to design and build.

I am bored today at work.
