How to Adjust a Koni Shock

ADJUSTMENT PROCEDURE 26, 28, 30 SERIES


Rebound adjustable, the adjustment is made with the shock fully extended.

  1. Remove the dust cover and expose the adjusting button (figure 2).
  2. Hold the damper body by hand where the piston rod emerges from the cylinder. Push the button carefully, by hand, and hold it in that position (figure 1 & 2). (Do not use any device, other than by hand to depress button).
  3. The adjusting device has been provided with a number if clearly distinguishable stops (clicks), each of which marks an adjustment position (zero + 3 clicks = 4 positions) (figure 4).
  4. The damper may have already been adjusted earlier. Therefore, check whether the shock absorber is in the position by turning the piston rod to the left (counterclockwise) with the other hand until the zero-stop is felt - DO NOT USE FORCE!
  5. To increase rebound, turn the piston rod one or more clicks to the right (clockwise), and release the adjusting button.
  6. Be sure the adjusting button fully springs back into position. As long as the button is depressed, do not turn the piston rod further; otherwise correct adjustment will be disturbed. As soon as the button has made it's complete return, the piston rod bay be turned freely. The damper can now be refitted.

 

 

 


Do not clamp here!

Figure 2: The handy adjustment button. Depress the button while turning clockwise to give increased damping forces.

Rebound Adjustment Procedures

  1. Remove the shock absorber from the vehicle and hold it vertically with the lower eye or pin attached in a vise. Use clamp plates to prevent damage.
  2. Fully collapse the shock absorber, at the same time turning the dust cap or piston rod slowly to the left (counterclockwise), until it is felt that the cams of the adjustment nut engage in the recesses of the foot valve assembly.
  3. Some shock absorbers include a bump rubber concealed under the dust cover and it must be removed prior to adjusting.
  4. The damper may have already been adjusted. Therefore check whether the shock absorber is in the adjustment position or not by keeping it collapsed and gently turning it further to the left counting at the same time the half turns until a stop is felt. Stop turning then and do not use force.
  5. Keeping the shock absorber collapsed, make 1 half turn (180 degrees) to the right (clockwise). In case of prior adjustment add the number of half the turns previously found. The total range is about 5 half turns.
  6. Pull the shock absorber out vertically without turning for at least 1 cm to disengage the adjusting mechanism. The dust cap or piston rod may now be turned freely.

Rebound Adjustment Procedures

 

 

 

 

 

 


Koni compress to adjust shock
Rebound Adjusting knob


Figure 1: Move pin left or right to 
increase rebound forces (counter-clockwise) Rebound - Insert a pin into the slotted adjuster located at the top eye (figure 1). Moving the pin from left to right (counterclockwise) will cause the forces to increase. From the minimum or factory positions, there are 12 possible sweeps of adjustment ( 1 sweep equals 1/4 turn).

 

 

Externally Adjustable. These dampers can be adjusted, literally at the turn of a knob (or sweep window as in figure 1), a technique borrowed from Formula-1 racing where KONI dampers have dominated the field for years. One can switch back and forth, in most cases in a matter of seconds, from a comfortable "touring" setting to a more firmer setting for a sporty drive. By means of a knob damping forces can be altered to driving conditions or personal preferences.

Turning the screw driver from left to right (clockwise) will cause the forces to increase. From the minimum or factory positions, there are 12 possible "clicks" of adjustment.

Rebound Adjustment Procedures
Independently adjustable in both compression and rebound this series racing shock absorbers offer over 140 different combinations and rebound, to finely tune the chassis for maximum performance.
