Class 3 Trailer Hitch Ball Mount
Choosing a Class 3 trailer hitch ball mount means matching three ratings at once: the receiver, the ball mount platform, and the trailer's coupler. A Class 3 receiver is common on light trucks and full-size SUVs, but the ball mount itself carries its own gross trailer weight and tongue weight limits. The shank size, rise or drop, and hitch pin hole all affect how the loaded trailer tracks. Buyers should begin with the vehicle's receiver rating and the trailer's loaded weight, then pick a ball mount that meets or exceeds both the gross vehicle weight rating and the tongue load for that configuration.
The direct answer
The core answer is that a Class 3 trailer hitch ball mount should be selected by confirming the receiver opening matches the shank, the ball platform is rated for the trailer's gross vehicle weight rating, and the ball diameter fits the coupler. Class 3 receivers generally accept a 2-inch shank, but receiver ratings can vary by vehicle and hitch manufacturer. The ball mount's stamped ratings must cover the total loaded trailer, not just the empty trailer, and the tongue weight must stay within the mount's vertical load capacity for the chosen rise or drop configuration.
A practical next step is to weigh the loaded trailer when possible, then compare that figure with the receiver label and the ball mount markings. The tongue weight should be roughly 10 to 15 percent of the loaded trailer weight for conventional towing, but the ball mount's maximum tongue rating takes priority. If the receiver is rated higher than the ball mount, the lower component controls the system. Axle ratings and the combined weight rating of the tow vehicle also matter because exceeding them can overload the rear axle or suspension even when the hitch components are within their individual limits.
