Koni Adjustable Racing Mono Tube Shock Absorber 30 Series Oval Track 6in Low Gas

Monotube design shock absorber. 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). Monotube design shock absorbers, sometimes referred to as high pressure nitrogen gas shock absorbers, have a single tube in which the shock components operate in. This design works without a reservoir tube, instead the oil capacity is controlled with a floating piston. The floating piston is important in keeping the oil and nitrogen gas separated during the stroke of the shock absorber, when the damper is controlling the suspension of the vehicle. With no reservoir tube, there is a need to store the oil that is displaced by the rod when entering the cylinder. This is achieved by making the oil capacity of the cylinder adaptable. The cylinder is not completely filled with oil, with the lower part containing nitrogen gas. Nitrogen gas and oil are separated by the floating piston. When the piston rod moves in and out the oil flows through the piston generating bump and rebound damping and ultimately controlling the movement of your vehicle.
