Abstract: A device for eliminating radial tilting in a receiver-type hitch due to rotational moment on the shank includes a collar, and three adjustment bolts. The collar has a center bar and a pair of side walls forming a U-shaped bracket that can fit over a reinforcing lip of the hitch receiver tube. A front wall on the collar has an opening for receiving a mount shank as it enters the receiver tube. The three adjustment bolts extend through the center bar to tighten the collar onto the hitch receiver tube. When the center adjustment bolt is tightened, the collar is secured onto the hitch receiver tube. When the adjustment bolts are tightened, the center bar of the collar moves downward away from the receiver tube, causing the opening in the front wall to pull down the shank against the inner wall of the tube and prevent radial tilting within the tube.
