Expanding on the already vast Supershock range Powerdown’s super responsive low pressure gas shock absorbers take performance & endurance to the next level.

This is achieved by incorporating the following heavy duty features:

  • Low pressure gas to keep the unit operating at lower temperatures
  • Large 45 mm disc valve European design for extra control & load protection
  • Advanced low friction high temperature seal
  • Increased body size for extra oil capacity
  • High tensile strength

The Benefits

  • Low Pressure Gas

    Keeps the unit operating at lower temperatures.

  • Heavy Duty with Increased Dampening Rate

    For our roads which can vary from a highway to narrow bitumen and gravel within a matter of a few kilometres.

  • Larger Oil Capacity

    Vastly improving the shock absorbers ability to dissipate heat and operate cooler under hard working conditions.

  • Extra Comfort & 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.

Black Eye Ring

Features

Eye Rings

360° Welds & One piece Eye Rings for increased strength and durability

Body & Shields

Increased body size for extra oil capacity

Different Shields – the thinner plastic shield allows for fitment in tighter spaces where a steel dust shield will not fit.

High Tensile

Materials, fittings & welds As illustrated in the Finite Elements Analysis stress test images.

Engineered for Performance

Large bore sizes – 45 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 our roads and higher load constraints

Powerdown shock absorbers achieve enhanced performance and longevity through

  1. Larger external body sizes
  2. Improved dampening
  3. Increased piston sizes
  4. High temperature oil
  5. Seals resistant to elevated temperatures
