✓ Advanced Vacuum Filling Technology

The 4S4L removes air from each damper using multiple vacuum and oil fill cycles. The created vacuum draws the oil into the shock absorber, after which an oil pump completely fills the damper. The result: no air in the dampers and optimal performance.

✓ Fast and Repeatable Results

  • Total process time: 3-5 minutes (based on 2 cycles and 4 dampers)
  • Adjustable oil pump runtime (5–80 seconds)
  • Number of vacuum and oil fill cycles adjustable (2–4 times)
  • Maximum pressure of 5 bar, monitored by internal sensors

✓ Fill Up to 4 Shock Absorbers Simultaneously

Whether you’re working with dampers from 1cc to 2000cc, the Shockfiller 4S4L automatically adapts – no need to adjust settings.

✓ Easy Operation

Designed for maximum efficiency:

  • Start with a single button press
  • Automatic oil supply from an external container (self-priming from oil drum or with pressure line up to 5 bar)
  • Internal vacuum pump
  • Sensor-controlled automation for reliable filling

✓ No External Compressed Air Needed

The 4S4L is developed to remove all air from the damper and fill it with oil. This machine does not press the oil into the shock absorber with compressed air but uses an oil pump. As a result, no unwanted air returns into the shock absorber.

✓ Suitable for Production, Workshop, and Test Environments

The machine is highly suitable for use in a production environment where continuous work is done. Its compact, portable, and robust design also makes the machine ideal for development teams, use on the circuit, or shock absorber tuners on the go.

Technical Specifications:

  • Voltage: 230V AC
  • Power: 800W
  • Maximum volume: 4 liters per cycle
  • Vacuum and pressure are monitored per cycle
  • Fully automatic oil processing and refilling

SHOCKFILLER 4S2L

The Shockfiller 4S2L was our first fully automatic shock absorber filling machine. Although it is still widely used, it has now been replaced by our further developed 4S4L. This machine is faster, more compact, and more efficient than its predecessor
