Adjustment Style

Internal Adjustment

KONI developed and manufactured the first adjustable telescopic shock absorbers and continue to innovate adjustment technology in each product.

KONI Internal Adjustment is used on the Twin-tube design shock absorbers.

This type of adjustment is made with the shock fully compressed and off the vehicle. How to use the internal adjustment?

With some internal adjustment shock absorbers, a bump stop must be removed from the dust cover prior to adjustment.

The adjustment process in this shock absorber does not have set clicks, rather the adjuster nut provides the freedom to fine tune your settings to suit your car needs.

To adjust, gently and with care fully collapse the shock absorber. When you feel it hit the bottom and stop, slowly turn the piston rod or dust cover to the left (counterclockwise) until you feel the cams of the adjustment nut engage into the foot / bottom valve assembly.

Which direction to adjust the shock?

Keeping the shock absorber collapsed and the adjustment nut engaged, adjustment can then be made by turning the the piston rod or dust cover to the right (clockwise). The recommendation is to make incremental, half turn (180 degree) adjustments. The total range can vary, but is usually between 4-6 half turns.

Pull the shock absorber out vertically without turning for at least 1 cm to disengage the adjusting mechanism.

If a bump rubber was removed, ensure this is replaced as failure to do so can result in internal damage occurring.

Clockwise: Firmer
Counter Clockwise: Softer

Design Construction

Twin-tube Design

KONI shock absorbers come in two different constructions:

Monotube design or
Twin-tube design.

Our engineers tailor shock absorbers for each application choosing the best design construction to suit your vehicle.

No matter which type of shock absorber application your vehicle uses, the general principle of each is to convert kinetic energy (movement) into thermic energy (heat).
