If you know the brands there are lots of spring charts on the web. If not you could get a spring dyno but they are expensive (a lot more then just buying a new complete spring set)

Or build your own spring tester. All you need is a digital scale and something to compress the spring an exact amount. I use a drill press.

What I do is get a drill press set it to where it will only go down so far and do all the springs this way with the scale underneath the spring

u could rig a holder and a micrometer such that when u had a given amt of weight and the spring drops 1in, then u have ur rate. crude but efficient for the job.
