        Drive shaft safety loop

        Easy to install and fit great. If you are planning on making power or doing any power adders i highly recommend. The NHRA requires it with any power adders.

        I bought a aluminum driveshaft and figured may as well buy a safety loop but did not want to drill any holes in the car and then i seen this one which is a super nice setup no drilling required fits nice and is a very sturdy product would recommend this safety loop to anybody.

      So this unit will work on a T56 Magnum?

      • This driveshaft safety loop will fit on TKO-500/600's and TR-3550's with partially removing the torque arm boss would be required. This will not fit on the T56 transmissions.

      Will this driveshaft loop work with a aftermarket transmission mount or does it have to be stock OE?

      • We have not heard of any issues with installing the Stifflers Driveshaft Safety Loop with aftermarket trans mounts.

      What driveshaft safety loops do you carry that will work with a T-56 magnum? I have a 2004 Mustang Mach 1.

      • The Stifflers Driveshaft Safety Loop will work with the T-56 Magnum installed.

      Will this product fit on a 2004 Mustang Mach 1. I am running a T-56 magnum transmission. Also do most guys/gals use two driveshaft safety loops? One for the back and one for the front? If I don't use an item what is your company's return policy?

      • The Stifflers Driveshaft Safety Loop is built to be used on all 99-04 Mustangs. You only really need to use one. We have a 30 day rerun policy.
