Here is a must have addition to your high performance or racing vehicle. This is a Heavy-Duty bolt-on Driveshaft Safety Loop. This part is required by many race-sanctioning bodies. You must have one in place before you race! These heavy gauge steel loops are adjustable to accommodate a variety of cars. The loop can be easily unbolted to aid in the removal of the driveshaft for service. They are a great addition to many cars and trucks. These are a good idea for ANY vehicle that is spinning the driveshaft at high speeds. If you have ever broken a U-joint at 60 miles an hour and seen the damage done by the driveshaft, you know why. Having one of these in place can save you thousands of dollars. They are a great measure of added protection for a street vehicle and a must have item for you weekend racers.
