Protect your 2007-2014 Mustang Shelby GT500, while complying with NHRA safety rules with a Driveshaft Safety Loop from BMR Suspension. If you drag race your GT500, chances are you need a driveshaft safety loop to be NHRA legal. Built from 1/4-inch laser-cut CNC-formed plate steel, BMR’s Driveshaft Safety Loop bolts-on using OE mounting holes from the factory transmission crossmember. This design gives you a solidly mounted loop that will stay in place should a driveshaft or transmission failure occur.
