Select your desired Hitch Ball Size in the drop-down menu above.
These customized Hitch Balls are designed to work with our Ball Mount locking process. The two weld spots lock the ball in place, preventing it from spinning inside of the trailer coupler. All Hitch Balls have a 1-1/4" diameter shank.
Carrier 13K trailer dollies – Please contact us to purchase hitch balls without welds.
Trailer dollies purchased before June 11th, 2021 – you will need to purchase a new Ball Mount kit, as we no longer support the old 1" diameter shank size. PleaseContact Usfor details.
If you need an extra Hitch Ball, we have a wide range of sizes available:
Yes!Each trailer dolly includes a hitch adapter that's compatible with most ball mount trailer couplers. See the Transformer, Carrier or Accessories page for additional connections. All electric models include batteries, charging cables, hardware and built-in safety features so you can park with confidence.
GVWR (Gross Vehicle Weight Rating) includes the capacity of your trailer (how much you can put in it, including passengers). This is different from the dry weight, or unloaded vehicle weight (UVW), which is the weight of your trailer when empty.
Tongue weight is the downward force that the trailer tongue applies to the hitch when connected to the trailer dolly. Using your Parkit360 for a trailer with too much or too little tongue weight could make moving and steering difficult, or cause issues with traction. We recommend that your tongue weight be 10% of your trailer's gross weight (GVWR), although this may vary for smaller trailers.
If you are not completely satisfied with your Trailer Dolly, customers in the Mainland US and Canada can return their unit up to 30 days after receiving their dolly for a refund, minus a flat return shipping cost and restocking fee.
Parts Only and International Trailer Dolly orders are not eligible for return.
