  • Non-contact height sensor requires no lines or controls in the cab
  • Improved, weather-resistant harness and durable components meet OEM standards for quality and function
  • Single-path system (#25490) allows two air springs to inflate simultaneously, while the dual-path system (#25491) inflates left and right springs independently, depending on load
  • Kit comes with a pre-assembled wiring harness, electronic sensor system, compressor and illustrated instruction manual for easy installation
