Reese Towpower 21901 Interlock Ball Mount
The Reese 21901 is a Class II interlock ball mount designed for light-to-moderate towing tasks. It features a 1-1/4 inch drop, which helps level lighter trailers when paired with compatible receivers. This model emphasizes straightforward use and a compact form factor, making it suitable for smaller trucks, SUVs, or cars that require a simple, reliable setup.

A potential limitation is the data indicating manufacturing in China, which may matter for users seeking domestic production.
Reese Towpower 21900 Interlock Ball Mount
The 21900 Interlock Ball Mount is a Class II option with a 3,500-pound gross towing capacity. It provides a 2.5 inch drop and a 2 inch rise to help level trailers effectively. The ball mounting hole is 3/4 inch, designed for a 2-1/2 inch ball shank setup, and it’s best for mid-sized trailers and light commercial applications. Choose this if you need stronger leveling while staying within Class II limits. Limitations include the 3/4″ hole for the ball shank, not ideal for 1″ shanks.
CURT Manufacturing 45030 Class III 2″ Ball Mount

This model includes a 1″ ball hole for quick ball changes and is ideal for heavier trailers. Best for those needing robust performance and broad compatibility; however, ensure your hitch and ball are matched to the rated weight.

It includes a 2″ tow ball, anti-theft steel lock, pins, and clips, making it a practical choice for households with several trailers or different cars. Best for buyers needing versatile positioning and security; a potential limitation is the heavier configuration that may require more handling during setup.
MaxxHaul 50547 Trailer Hitch Mount
The MaxxHaul 50547 is a rugged option featuring a heavy-duty welded construction and a weather-resistant black powder coat. It fits 2″ x 2″ receivers and includes a 2″ ball with a 1″ shank, plus a 5/8″ pin and clip for secure operation. With a capacity rating around 7,500 pounds gross trailer weight, this model targets heavier-duty, industrial-style towing. Best for users needing strong, durable performance in challenging environments; the drawback is its bulk and potentially heavier handling during installation.
Buying Guide
What to consider when choosing an interlock trailer ball mount:
- Receiver size and compatibility: Most interlock mounts fit 2″ x 2″ receivers. Confirm your hitch’s size before purchasing.
- Towing capacity: Match the gross trailer weight (and tongue weight) to the mount’s rating. Higher Class numbers generally indicate stronger builds.
- Drop and rise: Decide whether you need a drop for level towing or a rise for clearance in steeper scenarios. Some mounts offer adjustable positions to cover multiple vehicles.
- Material and finish: Look for high-strength steel with corrosion-resistant finishes for longevity in weather exposure.
- Security features: Some models include anti-theft pins or interlock mechanisms to prevent tampering.
- Ease of use: Simple interlock designs and included pins/clips speed up hitching and reduce setup complexity.
