If you frequent the drag-strip, or other sanctioned racing activities, at some point you may find yourself in need of a driveshaft safety loop. If you run sticky tires, or you’re going fast enough to justify it, the track or sanctioning body will likely require one of these for safety.
Back in the early days of the Fox body craze, most driveshaft loops required that you drill holes in your floorboard in order to mount them. That was fine for a car that didn’t see a lot of street time, or rainy weather, but what about those of us that daily drive our cars? Fortunately technology has improved and BMR Suspension has a solution for S550 owners with its driveshaft safety loop that bolts directly to the transmission cross-member.
Step one in our installation is to install the loop over the driveshaft. We moved ours forward in front of the shifter in order to avoid any interference. Once in place let this piece hang until you have the mount installed.
BMR’s part number DSL017 is made from 0.25-inch laser cut, CNC-formed steel. BMR includes Grade 8 hardware, which includes longer bolts and new washers to secure the driveshaft safety loop and cross member in position, accounting for the need for additional bolt length. The part comes powdercoated in either red or black. This driveshaft safety loop will satisfy the tech inspectors, and keep your driveshaft from coming through the floorpan or digging into the track should you break the transmission or driveshaft.
BMR supplies new hardware for the cross-member to ensure there's enough bolt-length for securing the cross member and the driveshaft loop properly.
BMR sent us one of these driveshaft safety loops in red for our Project 5-liter Eater 2015 EcoBoost Mustang. Even with aftermarket exhaust installed, and an aftermarket shifter, this part goes on in about 15 minutes. You will need a jack or other means to support the transmission while you remove the cross-member bolts and install the driveshaft loop. you can do this job on your garage floor with a jack and jack stands, but a lift does make it much easier.
Our final step was to install the four bolts, nuts, and eight washers that secure the loop to the bracket. Total install time about 15 minutes.
In our case we needed to install everything as far forward as possible in order to clear our shifter. It’s a tight fit, but there’s adequate clearance for the driveshaft and the shifter. We also had to have a friend help by moving the exhaust mid-pipe slightly to the side with a pry bar so that we could remove the passenger side rear bolt from the cross-member and install the new one. This could have been done with one person, having a pal to assist just makes it that much easier. With stock exhaust this is probably not an issue, but with some aftermarket systems it may be necessary to move or even remove the exhaust mid-pipe for this installation.
With our driveshaft loop in place, we’re one step closer to being ready for racing season thanks to help from BMR Suspension.
