Supershock Shock Absorbers

The Supershock was the first Australian designed shock absorber for air suspension applications on trucks and trailers.

Combining the following heavy duty features the Powerdown Supershock will provide the ultimate protection for your truck & trailer against road vibration damage and achieve the best possible life for your tyres.

Large bore sizes – 41 mm, 45 mm & 52 mm
Increased oil capacity vastly improving the shock absorbers ability to dissipate heat and operate cooler over long distances and constant high speeds
Upgraded dampening forces for African roads and higher horsepower engines, unlike products designed for Europe or North America
Viton seal & high temperature oil to withstand higher operating temperatures longer, outlasting standard oils and rubber seals
360° welds & one piece eye rings for increased strength and durability

Load & Vehicle Protection

Powerdown Supershock will significantly improve the performance of your truck, trailer or bus suspension in terms of vehicle stability, load protection and increasing overall tyre life.

The Benefits

Heavy duty with increased dampening rate
For African roads which can vary from a highway to narrow tar and gravel within a matter of a few kilometres.
High temperature fluid and viton seals
Withstand higher operating temperatures longer, outlasting standard oils and rubber seals.
Larger Oil Capacity
Vastly improving the shock absorbers ability to dissipate heat and operate cooler under hard working conditions.
Extra comfort and control
Powerdown shock absorbers will not only significantly improve driver comfort and control by keeping the vehicle’s tyres in contact with the road surface, there will be also additional cost savings in tyre and suspension wear.

Features

Eye Rings

360° welds & one piece eye rings for increased strength and durability

Polyurethane bushes developed from high-quality urethane elastomers have the capacity to bear high loads in tension and compression.

Supershock in Action

Supershock on Dyno

Our engineers and R&D team at Powerdown test all shocks using our variable stroke dynometer. Data is fed through the computer to simulate corrugations and dipping dirt roads to work the shock absorber to it limitations. This data loop is then replayed multiple times to determine seal life and shock absorber fade at certain temperatures. The results of these dyno tests help our engineers develop better designed shocks for all conditions.

Freightliner - Supershock

This is a Supershock fitted to a Frieghtliner with a displacement sensor fitted. Powerdown have the capability to collect data from a vehicles ride characteristics through fitting sensors to the suspension as see here.
