The NHRA Technical Department has modified the 2014 Header Collector ruling

A rule amendment will be made to the 2014 rule book to allow either an NHRA accepted tethering system or a minimum ½” (half inch) stich weld located on each primary tube.

The NHRA Technical department has also received numerous requests and submittals from various manufacturers for acceptance of their tethering systems.  Please continue to monitor the NHRA Accepted Product listing, which can be found on www.NHRARacer.com , for additional manufacturers as they are accepted and added to the list.  

The NHRA Technical Department will not accept Tethering System requests from individual racers, as this will inundate our resources and create an impossible situation to regulate in the field. Therefore, material sent from individual racers will not be reviewed for acceptance.  Only legitimate manufacturers planning to market a tethering system should submit a request.
