Different parts than expected.
There was 2 different part numbers for this item, but the two parts were not alike when it came down to the sizes of nuts and the way to hold them when bolting them in. One of them had a bolt in the back you could grab onto with an open end wrench, and the other I had to hold with a vise grip to stop it from spinning because there was no holding spots on the bolt. Otherwise it seemed to do the job.
This set was a wonderful addition to the Belltech 2/4 drop I did on my Yukon. These anti sway bars allows me to take bends and curves with more certainty. My truck has a very roadfeel as I drive in mountain passes. It was very easy to install with a time of 1 hour with hand tools in the rear. 1 hour in the front with airtools.
