How to Select Correct Ball Mount to Keep Trailer Level When Towed with Lowered 2013 Toyota Sienna

The desired situation when towing is that your choice of ball mount will allow your trailer's frame to remain level with the ground when hitched, since level trailers handle better. Towing with either a lowered or lifted vehicle can make it a challenge to keep the trailer level.

Vans like the Toyota Sienna and Honda Odyssey are pretty low to the ground in their stock form so any additional lowering will not help. For instance, when we installed Curt hitch # C13105 on a stock 2013 Sienna the top of the receiver opening was 11-inches above ground. The bottom of the hitch tube would then be only about 8-1/2-inches above ground.

The linked article will show you how to determine the exact amount of rise or drop you need from a ball mount. You can then use the linked page for 2-inch ball mounts to select one with the correct rise or drop, and weight capacity. Typically you will keep more ground clearance by using a fixed ball mount like # D-4 rather than an adjustable one like # C45900 which extends down lower.

You cannot use adapter MT70070 to give you increased height. The top receiver opening is only for use with accessories, but not for towing.
