CURT Class 4 Ball Mount is a heavy-duty, 2" shank tow mount rated for a 10,000 lb gross trailer weight and 1,000 lb tongue weight, with a 2" drop (flip to 1" rise) and a 1-1/4" ball hole.

This solid steel ball mount from CURT is engineered for demanding towing tasks where strength, fit, and corrosion resistance matter.

How strong is this ball mount for heavy towing?

The CURT Class 4 unit provides a gross trailer weight (GTW) capacity of 10,000 lbs and a tongue weight rating of 1,000 lbs, suitable for many large towing applications. Always confirm the lowest rating across vehicle, hitch, and trailer before towing to ensure safe operation.

• 10,000 lb gross trailer weight capacity
• 1,000 lb tongue weight rating
• Works with CURT Class 4 trailer hitches and other compatible systems

What are the size and fit details I need to know?

This mount uses a standard 2" x 2" shank to slide into a common receiver and measures 9-3/8" in overall length for correct ball positioning. The 1-1/4" hole accepts trailer balls with a 1-1/4" shank, and the hollow shank allows use of anti-rattle pins or locks.

• 2" x 2" receiver shank fits standard full-size hitches
• 9-3/8" overall length positions trailer ball properly
• 1-1/4" ball hole accepts 1-1/4" shank trailer balls

Can I adjust trailer height with this mount?

The mount offers a two-position height option: a 2" drop for lower trailers or flip it over to gain a 1" rise, giving you quick, mechanical leveling without extra adapters. This simple versatility helps match trailer tongue height to your vehicle quickly and securely.

• 2" drop standard setting for lower trailer tongues
• Flip to provide 1" rise when needed
• Eliminates the need for extra shims or adapters in many setups

How durable and well-finished is the ball mount?

CURT manufactures this mount with CNC forming, robotic welding, and mechanical descaling for consistent fit and finish. A gloss black powder coat protects against rust, chipping, and UV exposure so the mount stays functional and looks good through heavy use.

• CNC-formed for accurate dimensions and consistent fit
• Robotically welded and mechanically descaled for strength and smooth finish
• Gloss black powder coat for superior corrosion and chip resistance

Who is this for? The CURT Class 4 Ball Mount is aimed at vehicle owners who tow heavy loads regularly—owners of boats, travel trailers, utility haulers, livestock trailers, and light industrial trailers. It’s for drivers who need a rugged, precisely made ball mount with built-in options for anti-rattle hardware and quick height adjustment, while matching standard 2" receiver systems.
