A driveshaft safety loop is an essential part of any high-performance front-engine, rear-wheel-drive vehicle.

In fact, many tracks and race sanctioning bodies require one once you reach a certain speed/elapsed time threshold, or if you’re running specific tire types (e.g. slicks).

Basically, what a driveshaft loop does is keep your driveshaft from whipping out of control if you happen to shear a yoke, U-joint, or if the driveshaft itself splits. It protects you and your car from catastrophic damage caused by a flailing driveshaft.

How easy? The folks at Stifflers Suspension installed one of its driveshaft safety loops on a 2015 Ford Mustang in about an hour.

Better still, they filmed the process—check it out:
