Special FSD Series Shock – Front

KONI FSD Series gold-finish twin-tube strut.

The first shock absorber that offers superior handling without compromising comfort. You cant find a better shock for your motorhome than FSD: KONI frequency selective dampers. We have combined the benefits of performance and comfort into one shock absorber. FSD is firm for control over large bumps and corners, but soft for comfort over expansion joints and rough roads. While KONI is known to reduce bouncing in motorhomes, our FSD shocks include a special valve that filters out annoying vibrations before they enter the coach. The result is an incredibly smooth ride, with plenty of shock left to control pitching and swaying.

Features:

• Excellent ride quality on all road surfaces
• Improved control
• Reduced road noise
• Gold metallic finish shocks
• Less expensive than electronic systems
• Limited Lifetime Warranty

What ARE Twin-Tube Shocks?

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. When the piston rod is pushed in, oil flows without resistance from below the piston through the orifices and the non-return valve to the volume above the piston. Simultaneously, a quantity of oil is displaced and forced to flow through the bottom valve into the reservoir tube. The resistance, encountered by the oil on passing through the bottom valve, generates the bump damping. When the piston rod is pulled out, the oil above the piston is pressurized and forced to flow through the piston. The resistance, encountered by the oil on passing through the piston, generates the rebound damping.
