Reese 7039300 Interlock Class 3 Trailer Hitch Kit 5,000 lbs. 🚚

This Reese Class 3 ball mount kit brings a straightforward towing solution for light trucks and SUVs, combining a durable ball mount with a quick one-handed tightening system to simplify hitching a trailer. It is designed for use with 2 inch square receivers and offers a 3.25 inch drop that helps achieve a level tow when paired with the appropriate trailer height.

Key Points

The kit includes a 2 inch trailer ball and the Reese interlock ball mount, rated for a maximum gross trailer weight of 5,000 lbs and a tongue weight of up to 500 lbs, according to the manufacturer. The interlock tightening system allows the mount to be secured using one hand, which can speed up hookup and reduce fumbling when connecting. Keep in mind you should always consult your vehicle owner's manual for the maximum towing and tongue weight capacities specific to your vehicle.

Usage Recommendations

For level towing, measure the hitch height on your tow vehicle and the trailer coupler height before selecting the mount orientation. The 3.25 inch drop is commonly used with trailers that sit slightly lower than the vehicle hitch point, while the 2 inch rise can correct small mismatches when the trailer sits higher. The one-handed interlock tightening mechanism is useful when working alone, but verify the ball and mount are torqued and locked according to the included instructions before driving.

Positive Aspects

The compact 9.5 inch mount length makes it less likely to interfere with cargo access or rear sensors when compared to longer shanks. The kit’s clear ratings make it simple to match to trailers within the 5,000 lb class, and the interlock feature adds convenience during hookup. As a nuance, this mount is intended for 2 inch receiver systems and the capacities cited are those provided by the manufacturer, so actual safe towing limits depend on the vehicle, hitch, and trailer configuration.
