Installing Your Shock

If you are installing your shock on a bike for which the shock is not original equipment:

  1. Install the shock.
  2. Remove the main air chamber air cap and let all the air out of the main air chamber.
  3. Carefully cycle the suspension through its entire travel.
  4. Check that all parts of the shock are clear of the frame and swingarm as it cycles through the travel.
  5. Pressurize your main air chamber to a minimum of 50 psi and no more than 300 psi. You will tune to a more specific air pressure in the Setting Sag section below.
  6. Set sag.

General Maintenance

There may be a small amount of air sleeve lubricant residue on the body. This is normal. If this residual air sleeve lubricant is not present, this is an indication that the air sleeve should be re-lubricated. Some other things to consider for all shock models:

Before You Ride

  1. Clean the outside of your shock with only mild soap and water, and wipe dry with a soft dry rag.

    NOTE:  Do not use any solvents or de-greasers, as these products can damage the shock's exterior finish or its anodized parts.

    Do not spray water directly on the seal/shock body junction. Do not use a high pressure washer on your shock.

  2. Inspect the entire exterior of your shock. The shock should not be used if any of the exterior parts appear to be damaged. Contact your local dealer or FOX Racing Shox for further inspection or repair.
  3. Make sure that your quick-release levers (or thru-axle pinch bolts) are properly adjusted and tightened.
  4. Check your headset adjustment. If loose, adjust it accordingly to your bicycle manufacturer's recommendations.
  5. Check that all brake cables or hoses are properly fastened.
  6. Test the proper operation of your front and rear brakes on level ground.

Setting Sag

  1. Measure and set sag, and compare your result to the sag setting shown in the Air Spring Setting Guidelines table below.

  2. If your measured sag value doesn't match the table value, add or release air pressure in 5 PSI increments:
  3. Repeat until your target sag is achieved, then replace the air valve cap.

Climb. Trail. Descend.

With an easy flip of the blue CTD lever, you will quickly achieve optimum rear suspension performance for all types of riding terrain.

The blue CTD lever switches your riding platform modes. Rotating 120° between Descend mode position (shown below), change to Trail mode (when the CTD lever is positioned in line with the shock), and Climb mode (when the CTD lever is turned all the way clockwise, to the left).

Adjusting Rebound

Rebound controls the rate at which your shock returns after it has been compressed. The proper rebound setting is a personal preference, and changes with rider weight, riding style and conditions. A rule of thumb is that rebound should be as fast as possible without kicking back and pushing the rider off the saddle.

The rebound knob has 12-15 clicks of adjustment.

For slower rebound, turn the red adjuster control clockwise.

For faster rebound, turn the red adjuster control counter-clockwise.
