Borgeson collapsible shafts are safety components for automotive steering systems, designed to compress during a front-end collision to prevent the steering column from injuring the driver. The company offers several versions, including fixed-length shafts that collapse on impact and telescoping shafts that are adjustable during installation. 

These shafts are designed to maintain a fixed length during normal operation and only collapse in the event of an impact, meeting NHTSA safety guidelines. They are suitable for custom builds, street rods, and restorations.
