CURT Switch Ball Set — 1-7/8 in, 2 in & 2-5/16 in Trailer Balls (3,500–8,000 lbs)

Upgrade your towing versatility with CURT Switch Ball

CURT Switch Ball trailer balls redefine convenience for light- and medium-duty towing. By combining a sturdy shank with removable heads, the Switch Ball lets you swap ball sizes without swapping mounts. A simple twist releases the head for a quick change, while the J-groove design keeps the ball securely in place during transit. This approach minimizes clutter and helps you stay prepared for diverse loads on the road.

Three ball sizes are included in the set to cover common trailer couplers, with rated capacities that align with typical towing needs. The 1-7/8 in ball handles lighter utility trailers, the 2 in ball handles mid-range loads, and the 2-5/16 in ball is ready for larger trailers. Each head is designed to work with CURT’s 2-1/4 in long, 1 in diameter shank, providing a robust anchor that reduces friction at the coupler and helps the system maintain smooth operation from hitch to hitch.

• Fits 1-7/8 in, 2 in, or 2-5/16 in couplers for flexible towing options
• Exclusive J-groove design ensures a secure system when mounted
• No tools, coins, or pins required for head changes
• Shank carries the load, helping limit friction and binding at the coupler
• Constructed from high-strength steel with a bright nickel-chrome finish for resilience

Technical specs and safety testing

Shank length is 2-1/4 in with a 1 in diameter, designed to seat firmly in standard hitch setups. Each Switch Ball is independently tested in accordance with SAE J684 to verify performance under typical towing conditions. The durable steel construction paired with a bright nickel-chrome finish helps resist wear and corrosion over time.

Real-world use is guided by practical benefits: you can pair the right ball size with the right trailer in moments, reduce the number of mounts you need to carry, and enjoy a straightforward, tool-free head change when plans change on a trip. While results will vary by trailer and load, CURT’s Switch Ball provides a flexible option that may help you streamline your towing setup.
