CURT 45070 Class 3 Trailer Hitch Ball Mount - Strong, Simple Tow

In this review the CURT 45070 Class 3 ball mount is judged on strength, fit and everyday towing usefulness. It is best for truck and SUV owners who tow utility trailers, boats or campers and want a straightforward, durable ball mount that makes level towing easy. The single biggest reason to buy is its dependable strength: built from high-strength steel with a black powder coat, it delivers a high GTW and tongue weight rating while remaining simple to install and use.

Key Features

• High towing capacity: Rated for up to 7,500 lbs GTW and 750 lbs tongue weight in the 6-in drop position, it handles heavier trailers with confidence.
• Fits standard receivers: The 2-in x 2-in shank is compatible with industry-standard 2-in receivers, so it fits most pickup trucks and SUVs without adapters.
• Dual rise/drop geometry: Use the 6-in drop or 4-in rise to achieve a level trailer stance for safer, more stable towing.
• Corrosion resistance: A gloss black powder coat protects the steel from rain, road salt and grime, extending service life in wet climates.
• Simple installation: The rounded shank makes insertion into the receiver easy and it secures with a hitch pin for fast setup.

Who It's For

The CURT 45070 is ideal for owners of light trucks and SUVs who tow utility trailers, boat trailers, campers or similar loads and want a rugged, no-nonsense ball mount. It is especially useful when a 6-in drop is needed to level a trailer tongue and when a high tongue weight rating is required.

Those who need an integrated trailer ball, a class 4/5 heavy-duty mount, or a specialized adjustable hitch with many positions should look elsewhere; this product is a solid, fixed-position class 3 ball mount designed for common towing tasks rather than specialized or extra-heavy commercial towing.

Pros & Cons

Pros

• Robust build quality with heavy welds and a sturdy feel that customers describe as very strong.
• Very good value for the capacity, offering 7,500 lbs GTW in the drop position for common towing needs.
• Good fit and finish with a snug shank fit and limited rattling when installed in proper receivers.

Cons

• Trailer ball is not included, so buyers must purchase a 1-in diameter shank ball separately.
• Fixed drop/rise positions mean less flexibility than multi-position adjustable mounts for irregular trailer setups.

Specifications

Our Verdict

The CURT 45070 is a practical, well-built class 3 ball mount that offers strong towing capacity and corrosion-resistant protection at a reasonable cost. Truck and SUV owners who need a reliable, fixed-position mount for common trailers will find it hard to beat for value and durability, provided they plan to buy a separate 1-in trailer ball.
