This is a kind of a Band Aid to fix a problem with my front drive shaft not having enough travel. Since I installed the front missing link shackles, the front can droop a lot. This make the drive shaft to get out of the splines and fall on the ground. Not very practical. The best solution to this is to have the drive shaft modified to have longer splines, but it is expensive ($500-550CAN). So what I did, was to have the drive shaft lenghtened 3" and balanced($75CAN). This will keep the drive shaft from falling at extreme travel (one wheel compressed and one drooping) but doesn't solve the problem if I have the truck in the air and the two wheels drooping at the same time(It happens to me once every 3-4 years when I jump the truck so it's not a real problem). To overcome that, I made the limitting straps that are installed in the middle of the axle so it can keep the complete axle from drooping to much but doesn't make any restriction if the axle is working one side at the time.
