Tough Dog – Leading 4x4 Suspension Systems Since 1985
Tough Dog is a leading suspension brand for 4x4 vehicles, established in 1985. Well-known and proven products with an outstanding reputation are sought after by users worldwide. The brand’s distribution network currently covers 42 countries.
Tough Dog’s pioneering approach to research and development (R&D) has resulted in the introduction of several unique products to the market. The Return to Centre steering damper and the adjustable ‘SV’ steering damper are two excellent examples of the team’s innovative thinking, which has helped create some of the best suspension systems available for off-road vehicles today.
Tough Dog products have been repeatedly awarded for their unique design and performance. For example, the Tough Dog 41mm Foam Cell shock absorber won first place in an independent shock absorber test conducted by Australian 4WD Action magazine — in a country where suspension components face the toughest demands and where reliability is crucial due to long distances and extreme conditions.
The Foam Cell shock absorber, on which this kit is based, is our best-selling model, delivering versatile, all-round performance. Whether you take your vehicle off-road only occasionally on weekends or use it in rough terrain throughout the year, Foam Cell shocks can handle it all.
Foam Cell Technology
The “Foam Cell” insert, made from microcellular foam, significantly reduces cavitation, one of the main causes of shock absorber failure. Under high stress, oil and gas inside a standard shock absorber mix and create bubbles, reducing oil viscosity. When aerated oil passes through the valve, it offers less resistance, preventing the damper from functioning properly.
The Foam Cell insert fills the space that would normally contain air or nitrogen, eliminating the possibility of bubble formation. This ensures smooth operation and exceptional resistance to damping fade during extended heavy-duty use.
Adjustable Performance
With 9-stage adjustability, you can easily control the firmness of the shock absorbers and adapt to changing conditions. Choose a firmer setting for highway driving, then soften it when it’s time to hit the trails.
