Starting this weekend, NASCAR Cup Series teams have the option to run an Ohlins rear damper that includes a lift to help cars with flat rear tires return to pit road. The new design replaces the stock lower shaft end of the shock absorber with a new lift actuator.
Cars using these dampers will have a valve in the driver’s side A-post (pictured below). When a safety worker arrives at the car, they will use a tank of compressed air to jack the car up 2-3 inches, enough for it to be safely driven back to pit road. After the tires are changed, crew members can lower the car back down by pulling the valve.
