Get All The Benefits of 4.0 Fox Bypass Shocks
Fox 4.0 Bypass Shocks offer three main advantages: external adjustment, no cavitation on compression, and a progressive damping curve. The progressive damping curve is the most important and least well known advantage you can get when the internal valving is properly designed. Progressive damping curves eliminate harshness over bumps and whoops while still providing high speed control to get on top of the whoops. We offer exceptional service in order to help you dial in the proper internal valving on your 4.0 Fox Bypass Shocks.
