BMR Suspension designed the Driveshaft Safety Loop to contain a driveshaft, keeping it from ripping through the floor or digging into the track in event of a failure. It simply attaches to the factory transmission crossmember with supplied Grade 8 hardware. Other driveshaft loops attach to the transmission and can fail to contain the driveshaft in the event of a transmission failure. BMR designed their mopar driveshaft loops for street, drag race, and top speed applications. A Driveshaft Safety Loop is cheap insurance to protect your investment and provide peace-of-mind whether you are at the track or on the street. When performance is a must, rely on BMR Suspension!
