Very disappointed, just installed this twin stabilizer bar steering and it was very easy. My problem is that I've had two of the worst "death swings" of all time. I had to slow down to 15 mph to stop and I could continue. My tires are Mickey Thompson 315/70R17. The wobble was minimal at 50 mph with a shock stabilizer bar. Now he literally shakes the steering wheel out of his hand. :(
