CURT 45090 Class III 2" Ball Mount — 5,000 lb GTW / 500 lb TW (Drop) or 3,500 lb GTW / 350 lb TW (Rise) | Gloss Finish

Overview

The CURT 45090 Class III 2" Ball Mount is a robust towing accessory designed for pickup trucks and SUVs that frequently tow heavier trailers. It provides flexible height options so you can tailor trailer alignment to your load, road, and hitch setup without changing components.

Two positioning options for precise trailer leveling

Choose drop or rise to dial in trailer height. In drop mode, the mount yields an 8" drop for level towing on many boat and utility trailers. In rise mode, it offers a 6" rise to gain ground clearance and improved tongue weight control when needed.

Key specifications

• Fits trailer hitches with a 2" x 2" receiver tube opening
• Includes a 1" hole to accept a trailer ball shank
• 6" rise or 8" drop provide versatile trailer leveling
• Hollow shank weighs less and can be used with an anti-rattle kit
• CNC-formed, robotically welded and mechanically descaled for a precise fit

Finish, durability, and care

Built for the road, the mount features a durable gloss black powder coat that resists corrosion, scratches, and UV damage. Regular cleaning with mild soap helps maintain the finish and keeps the surface smooth for long-term use.

Capacity notes and safety tips

In drop position: up to 5,000 lbs gross trailer weight and 500 lbs tongue weight. In rise position: up to 3,500 lbs gross trailer weight and 350 lbs tongue weight. Always respect the lowest-rated component in your towing setup.

Real-world use cases

This ball mount is well suited for utility trailers, boat trailers, campers, and mid-range RV trailers paired with pickup trucks or larger SUVs. Its 11-1/2" length aids in weight distribution and mounting flexibility across common trailer configurations.

Care and installation tips

To preserve the finish, avoid abrasive cleaners. If you plan to use an anti-rattle kit with the hollow shank, follow the kit’s instructions. Regularly inspect the ball hole and shank for wear and ensure all components are within rated limits.

• Inspect weight ratings and avoid exceeding the lowest component rating
• Use an anti-rattle kit with the hollow shank if applicable
• Rinse off mud or salt after use and dry thoroughly
