CURT 2" Class III Ball Mount — 2" Drop, 7-1/2" Length, Gloss Black, 7,500 lb Capacity

The CURT 45030 Class III 2" Ball Mount is a heavy-duty hitch accessory designed to safely tow trailers up to 7,500 lb gross trailer weight and 750 lb tongue weight when paired with compatible equipment.

This precision-formed ball mount is built for pickup trucks and SUVs that use a standard 2" receiver. CNC-formed steel and robotic welding give it consistent strength, while a gloss black powder coat finish resists corrosion and road wear. The 7-1/2" length with a 2" drop (and up to 3/4" rise) helps you achieve a level trailer setup across a wide range of towing configurations. Always observe the lowest-rated component in your towing system when determining safe towing limits.

How much weight can this ball mount handle?

The CURT 45030 is rated for a gross trailer weight (GTW) of 7,500 pounds and a tongue weight (TW) of 750 pounds. These ratings assume the rest of your towing system — vehicle, hitch, ball, and trailer — meet or exceed those limits. Never exceed the capacity of the lowest-rated towing component.

• Gross trailer weight: 7,500 lb
• Tongue weight: 750 lb
• Follow lowest-rated component rule for safe towing

Will this fit my trailer hitch receiver and trailer ball?

This ball mount fits any standard 2" x 2" receiver shank and accepts a trailer ball with a 1" diameter shank through its 1" hole. Its rounded shank makes insertion easy and compatible with the large majority of Class III receivers installed on trucks and SUVs. Trailer ball and hitch pin are sold separately.

• Receiver shank: 2" x 2" standard size
• Ball hole diameter: 1" for 1" shank trailer balls
• Requires separate hitch pin and trailer ball purchase

How does the 7-1/2" length, 2" drop and 3/4" rise help towing?

The 7-1/2" overall length positions the trailer farther from the vehicle for better clearance and alignment. A 2" drop accommodates trailers whose coupler sits lower than the vehicle hitch, while the 3/4" rise option helps level trailers that sit slightly higher. These measurements make it easier to achieve a nearly level trailer for safer towing and smoother handling.

• Overall length: 7-1/2" for clearance and alignment
• Drop: 2" to lower couplers into level position
• Rise: 3/4" for small height adjustments

What construction and finish features protect durability?

CNC forming and robotic welding create consistent structural integrity across units, and mechanical descaling smooths the surface ahead of coating. The gloss black powder coat resists rust, scratches, and UV damage to extend service life and keep the mount looking good through road exposure. These manufacturing steps reduce weak points and help the mount hold up under repeated use.

• CNC-formed, robotically welded high-strength steel
• Mechanically descaled surface for better coating adhesion
• Gloss black powder coat for corrosion and abrasion resistance

Who is this for? The CURT 45030 serves owners of mid‑size and full‑size trucks or SUVs who tow utility trailers, boats, campers, or similar loads that fall within Class III capacity. It’s ideal for drivers who want a dependable, easy-to-install ball mount with corrosion resistance and precise manufacturing quality. Ensure your vehicle, hitch, and trailer components match or exceed the stated capacities before towing.
