If your Tiger has more horsepower and torque than the standard engine, or if you have added wider tires, you should think of adding a Drive Shaft Safety Loop.
The reason is that when the engine is developing lots of power, especially torque, and when the tires hook up, a lot of strain is put on the driveline. If your universal, especially the front one, is old or not up to the torque of your engine, it will give.
Then the driveline will be flopping around, and will probably drop to the ground, and if it digs in, then your drive shaft becomes a pole vault for the car.
At the very least, you dont want to have the drive shaft flopping around, if the front universal breaks.
The solution is a Drive Shaft Safety Loop. This is required by NHRA and IHRA, if you race, and for a good reason.
Summit sells one that meets NHRA and IHRA requirements, is very sturdy, adjustable, and sells for around $25. It is 2 wide, and 1/4 thick. www.Summit.com or 800-230-3030.
I put one on my Tiger, and here is what I did to fit it up.
