Description

Many bikes on the market suffer from harsh bottoming and a general lack of support deep in the travel while using a coil shock. Most manufacturers will remedy this by using an air shock for ease of set-up and the inherent progressive nature of an air spring to counteract the linear rear suspension action of particular bikes.

Race Only Springs have finally produced a progressive shock spring to give every performance benefit with zero drawbacks. These springs have all the same pedigree as their fork springs, produced to the absolute highest industry standards. With a spread of 7 rates in 25lb increments and a progression at 70% travel, these will transform how your bike handles.

As with all Race Only springs, they are produced in Germany in the world's leading coil spring facility by Eibach GMBH. They are produced with the same specifications as their high-end motorsport springs that are used in such series as F1, WRC, MotoGP, MXGP etc.

Key Features
  • Heat treated to ensure unparalleled rate accuracy.
  • Shot Peened to relieve surface stresses.
  • Block resistant to prevent spring shortening or rate change.
  • Coils are wound closer to provide a progressive rate.
  • Progression at 70% travel.
  • 75mm stroke.
  • 38mm ID.
