RideTech Replacement Shock Knobs

RideTech offers replacement shock knobs used on Ridetech coilovers and Shockwaves and HQ Series shocks. These glass filled nylon rebound knobs allow for easy adjustment of your RideTech shocks. There are two types of damping: compression and rebound. When you decrease rebound damping by turning the adjustment knob counter-clockwise, you allow the shock to extend faster. It feels softer, more supple, and livelier. When you increase rebound damping by turning the adjustment knob clockwise, you make the shock extend slower, so it feels stiffer, more supportive, and more planted.
