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.
Please note for use on non-MRP brands you will need a spring spacer kit due to the overall length of the spring, they can be found here. Please see the image for which spacer kit you need for non MRP shocks.
