I drove a truck with this conversion.
I didn't spend enough seat time to see if it made a huge difference with the wandering..
But I can say it took ALL the slop out of the box. You can grab my wheel of my truck going down the road and twist it back and forth about 4" each direction before the input gets to the tires. This was instant. Felt 110% better.
