High-Quality for Smooth Rides

Levels 4 - 6 are the choice for daily driving and control, with similar ride characteristics as the RS5000X series shock. Levels 7 -9 are excellent for towing and maximum control during fast off-road situations. This all in one shock allows for a 400% change in control from softest to firmest, making it the best choice for those that use their vehicles in varying driving situations.
