Piston Spring rate measurement

Our SU reference Catalogue gives details on the load ratings of each spring.

The easiest way to measure this is to cut a piece of card to fit inside the spring which is the correct length for the load to be added.

Then place the spring (and card) onto a suitable measuring scale and compress until the top of the spring is level with the card, then read the load rating.
