Progressive Spring

The revolutionary Progressive springs fit shocks of any length with 50 - 65mm of stroke. Progressive springs increase ending-stroke support by approximately 20% over linear coil springs - allowing them to be used on frames previously requiring the progressive nature of air suspension.
