CURT 2" Ball Mount Class III 45030 — 2" Drop, 7,500 lb Capacity, Gloss Black

The CURT 45030 is a Class III 2" ball mount built from CNC-formed steel with a 7,500 lb gross trailer weight rating and a durable gloss black powder coat.

This ball mount pairs with standard 2" trailer receivers to give trucks and SUVs a reliable, ready-to-tow connection for utility trailers, boat trailers, campers and other mid-size loads. CURT builds this model with robotically welded seams and mechanical descaling to ensure consistent fit and finish, then protects the surface with a thick powder-coat to resist corrosion and road wear.

How strong is this ball mount for towing heavy trailers?

The CURT 45030 is rated for up to 7,500 pounds gross trailer weight and a 750-pound tongue weight, but you should never exceed the lowest-rated component in your towing system (vehicle, hitch, mount or trailer). The heavy-gauge, CNC-formed steel and robotized welding provide the structural integrity behind those numbers.

• Gross trailer weight (GTW): 7,500 lb
• Tongue weight (TW): 750 lb
• Material: high-strength steel, CNC-formed
• Fabrication: robotically welded for consistent strength

Will this fit my vehicle’s receiver and trailer ball?

The 45030 is designed for industry-standard 2" x 2" receivers and accepts trailer balls with a 1" diameter shank through its 1" hole. Its shank profile and rounded corners make insertion straightforward, and it secures with a hitch pin (sold separately).

• Receiver shank size: 2" x 2" industry standard
• Ball hole: 1" diameter to accept 1" shank trailer balls
• Installation: insert shank, align pin hole, secure with hitch pin
• Compatibility: fits most pickup truck and SUV Class III hitches

What are the dimensions and rise/drop options for leveling?

This mount measures 7-1/2" in overall length and provides a 2" drop or a possible 3/4" rise depending on how you orient the shank and ball location. Those measurements help you achieve a level trailer connection or accommodate different trailer tongue heights.

• Overall length: 7-1/2"
• Drop: 2" (for trailers lower than vehicle hitch)
• Rise: 3/4" (when reversed for higher trailers)
• Use orientation to fine-tune trailer pitch for safer towing

How does the finish hold up to road and weather conditions?

CURT applies a gloss black powder coat after mechanically descaling each unit, which provides a robust barrier against rust, abrasions, UV fading and road salt. The finish both extends service life and keeps the mount looking factory-fresh under heavy use.

• Finish: gloss black powder coat for corrosion resistance
• Preparation: mechanical descaling ensures adhesion and smooth surface
• Durability: resists salt, moisture, dirt, and minor abrasions
• Maintenance: periodic cleaning and inspection prolong longevity

Who is this for: The CURT 45030 Class III ball mount is aimed at pickup truck and SUV owners who tow utility trailers, boats, campers or other mid-size loads and need a dependable, industry-standard 2" mount. It’s also a good choice for fleet operators or occasional haulers who want rugged construction, predictable fitment and a corrosion-resistant finish.
