CURT Class 4 Ball Mount 2" Shank, 10,000 lb Capacity — 2" Drop (Flips to 1" Rise), 9-3/8" Length

CURT’s Class 4 ball mount is a heavy-duty, gloss-black steel tow adapter with a 2" x 2" shank rated for 10,000 lbs. gross trailer weight and a 1,000 lb. tongue weight.

Built for demanding towing tasks, this ball mount pairs with 2" receiver hitches to tow large boats, RVs, and utility trailers. Its 2" drop (flip to 1" rise) helps level trailers; the hollow shank accepts anti-rattle pins to reduce noise and vibration. Precision-formed by CNC machinery and robot welding, the mount is finished in a durable powder coat for long-lasting corrosion and chip resistance.

How does this ball mount help with trailer leveling?

The mount offers a 2" drop that can be reversed to provide a 1" rise, letting you fine-tune coupler height for a level tow. Proper leveling reduces sway and improves braking and handling.

• 2" standard drop, flips to 1" rise for versatility
• 9-3/8" overall shank length for common hitch geometries
• Fits 1-1/4" ball shanks through the included hole

Is this ball mount strong enough for heavy loads?

Yes — the mount is rated for a 10,000 lb. gross trailer weight and 1,000 lb. tongue weight, suitable for many large trailers when not exceeding any vehicle or hitch limits. Ratings reflect the mount’s heavy-gauge steel construction and robotic welds that maintain consistent strength across units.

• 10,000 lb. gross trailer weight capacity
• 1,000 lb. tongue weight rating for safe hitch loading
• CNC-formed and robotically welded for repeatable structural integrity

What features reduce noise and wear during towing?

The hollow 2" shank accepts anti-rattle hitch pins or locks to minimize movement between mount and receiver, lowering noise and vibration. A gloss black powder coat helps protect against rust and chipping so the mount retains fit and finish through repeated use.

• Hollow shank accommodates anti-rattle pin or hitch lock
• Powder-coated finish resists rust, chipping, and UV fade
• Mechanically descaled surface improves paint adhesion and longevity

Will this mount fit my hitch and ball setup?

The CURT Class 4 mount is designed for 2" x 2" receiver tubes and accepts trailer balls with a 1-1/4" shank. Measure your receiver and ball shank diameter to confirm compatibility before installing.

• Standard 2" x 2" shank fits most Class 4 receivers
• 1-1/4" ball hole to accept common trailer ball shanks
• 9-3/8" length helps situate the coupler at correct distance from hitch

Who is this for: This ball mount is intended for owners of trucks, SUVs, and other vehicles equipped with 2" receivers who tow heavier loads such as boats, large campers, horse trailers, or industrial trailers. Choose this mount when you need a reliable, professionally manufactured Class 4 solution with flexible drop/rise options, anti-rattle compatibility, and a corrosion-resistant finish. Always confirm that the lowest-rated towing component (vehicle, hitch, ball, or trailer) governs your safe tow capacity and never exceed those limits.
