Koni 04-20 Spartan K2/K3 / 00-20 Spartan Mountain Master IFS Shock - Front

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). Twin-tube design shock absorbers, sometimes referred to as hydraulic or gas-hydraulic shock absorbers, have two tubes – one for the piston to work in and one known as a reservoir tube for the excess oil to move in and out of. As the piston rod moves in and out of the shock the oil moves through valves between the two tubes ensuring controlled damping occurs to control the suspension of the vehicle.
