Stabilizers are designed to operate under tension not compression. I adjust mine with no slop to minimize the heavy weight swinging around on hillsides. With the implement raised, I push it over and even pull on the stabilizer bar to even get the slop caused from the bars. Repeat on the other side. When you push on your implement, verify that the stabilizer that stops the motion is the tension one. I have a 30 HP tractor with loaded tires and many times a full loader of dirt doing figure 8's and hitting stumps and never bent one. Something is wrong with your setup. If moving forward, it should be next to impossible to damage these when traveling less than 10 MPH.
