Low Speed Compression on a shock refers to the rate at which the shaft compresses into the shock body. It typically happens during cornering, braking, accelerating, or when driving over large rolling bumps.

Since shocks must first react slowly to a bump before moving faster, low-speed compression can also be noticeable on high-speed bumps, especially if they are small and frequent (like washboard terrain) or if the valving is too stiff.

• If the vehicle feels bouncy or bottoms out on large rolling bumps, consider stiffening the Low Speed Compression on your DSC.
• For improved handling and to reduce brake dive, tighten the Low Speed Compression adjuster.
• If the ride is harsh on washboard roads or small bumps, soften the Low Speed Compression adjuster on your DSC.
• Low-speed adjustments on the DSC are highly effective and often the most useful for fine-tuning.

High Speed Compression occurs when the shock compresses rapidly, typically in response to more aggressive impacts, such as hitting curbs, speed bumps, whoops, or similar obstacles. This isn't necessarily tied to driving speed but to the intensity and quickness of the impact.

• If the suspension and tires are bottoming out or slamming through hard impacts, you should increase the high-speed compression.
• Due to the design of the DSC's internal components, high-speed compression adjustments are generally less noticeable or distinguishable compared to low-speed adjustments.
