The Original Equal-i-zer Sway Control Hitch can sometimes produce loud grinding or clanking noises because of high pressure and friction. These loud noises usually present themselves during the first few uses of a new hitch as it breaks in. They are also more prevalent during slow, tight turns where the tow vehicle and trailer are in a twist. The Sway Bracket Jackets were designed to quiet the ride by reducing some of the vibration caused as the spring arm slides back and forth on the L-bracket. Not compatible with the 4,000 pound Equal-i-zer hitch.
