Turning clockwise will increase the compression damping making it harder. Turning counter clockwise will decrease the compression damping making it softer. Compression adjustments affect the first two-thirds of travel while the last third is adjusted with internal valving.

Some suspensions are not consistent with these top and bottom locations and clockwise vs. counter clockwise directions. Also, in addition to normal compression damping most later model shocks have separate high and low speed compression adjustments. Always check your owners manual and be sure you are familiar with the adjustments locations and operation.

Rebound Damping: Rebound is the action of your suspension as it returns to its fully extended position after being compressed fully or partially. Your suspension will rebound as you launch off a jump, after you land and in between acceleration or braking bumps and whoops. The rebound damping adjustment for most rear shocks is usually a screw near the bottom of the shock where it attaches to the linkage. The rebound adjustments for most forks is usually a screw at the top on the fork caps. Some suspensions are not consistent with these usual locations so, always check your owners manual and be sure you know where the adjustments are located.

Preload: Preload, sometimes called race sag, reflects the difference between the suspension when it is fully extended and when it is compressed with the rider on the bike in riding position.  Correct spring preload depends on rider weight and will adjust the ride height of the motorcycle front and rear, thus affecting cornering and straight line stability. 

The wisest investment you can make to modifying  your motorcycle will be to the suspension. You can have all the power, accessories and graphics kits on the market, but they will not help you go your fastest until your suspension is properly adjusted and tuned for your style and ability. There are many variables on your forks and shock that can be adjusted... raised, lowered, increased and decreased... which will affect your landings, braking, acceleration, turning and straight line stability.  Each one of these adjustments can and does affect another one, so it is necessary to have all variables properly adjusted and the components clean and in good working condition to balance and optimize your suspension performance. Below is an outline of the fork and shock adjustments that you should be familiar with. Following that will be a summary on the best approach to getting the right combination. Print this out and read it over. By knowing exactly what you have, you can help us, at Shock Therapy, provide you with exactly what you need in the way of high performance custom suspension.

Compression Damping: Compression is the action of your suspension as it moves from fully extended towards a collapsed or compressed position. Your suspension compresses when you land from a jump, when you hammer through a section of whoops on a track or trail and during hard acceleration. The compression damping adjustment for most rear shocks is usually a knob or screw near the reservoir at the top of the shock. The compression damping adjustment for most forks is usually at the bottom of the fork leg.
