Heavy Track Series Shock – Front

Heavy Track Series red painted internally rebound-adjustable twin-tube low-pressure gas-charged shock absorber.

Shocking conditions or winding roads? When asphalt becomes boring and gravel, dirt and dust are too tempting, Heavy Track 4 x 4 shock absorbers by KONI are the ideal all-terrain option. These shock absorbers will deliver optimum road holding and comfort both on and offroad. Our 4 x 4 shock absorbers have been specially developed by KONI for 4WD’s and Sports Utility Vehicles (SUV’s). Tested under extreme conditions, these dampers satisfy the highest offroad demands with regards to safety, stability and grip. These shocks ensure greater stamina for both drivers and vehicles. Also on the road, you can count on greater comfort and a higher level of safety, more stability and better roadholding. In short, Heavy Track shock absorbers from KONI are perfect ‘all road’ shocks absorbers, irrespective of the driving conditions.
KONI Heavy Track shock absorbers are simply and completely rebound adjustable. This means that the rebound characteristic can be completely adapted to the circumstances. Furthermore, Heavy Track shock absorbers have large reserves of damping power available. And that’s not all. KONI shocks are of superior quality. This is not only evident from the robust construction but also from the materials used such as the seals which are resistant to high temperatures.

Features:

• Optimum handling, road holding and grip
• Adjustable rebound forces for all on and offroad conditions
• Specially developed, high quality materials for maximum performance
• Better driving characteristics
• Rugged construction
• Long lifespan

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.

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. 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.
