RAETECH's Bump Stop Load Cells are designed to accurately and reliably measure Bump Stop Loads on vehicles that incorporate the bump stop on the shock absorber. Elastomer Bump Stop material properties are loading rate and temperature dependent. Bump Stop characteristics measured in the lab are likely very different than experienced on the track.

Bump Stop Load Cells allow you to:

  • Identify when the Bump Stop makes contact
  • Quantify the Wheel Load reacted at the Bump Stop
  • Measure the actual Bump Stop Rate during operating conditions

RAETECH's Bump Stop Load Cells are designed with interchangeable end caps to accommodate different loading conditions. One cap is profiled for contact with the rigid end of the shock, while another is optimized to interface with the soft elastomer element. Adapters are available to clamp the load cell on the shock housing, keeping it attached to the sprung mass. Our load cells are engineered to operate in the harsh temperature and vibration environment found in motorsports applications.
