How to Find Rise/Drop of Ball Mount Needed for Towing Small Aluminum Boat with 2007 Acura TL

When we installed the Draw-Tite # 24755 Class I hitch on a 2007 Acura TL, we found that the inside top edge of the receiver tube sat 10-1/2 inches above the pavement.

To determine which ball mount would place your trailer as close to level as possible, you'll need to put the boat trailer up on it's jack so it's level, then measure from the bottom edge of the coupler to the ground. The height difference between 10-1/2 inches and the level trailer coupler height equals the amount of rise/drop you'll need. I'll link to an article that shows exactly how to do this.

In your case, you'll need a rise. The average trailer coupler height varies between around 16-18 inches with smaller trailers typically being lower. It's very likely that a 5 inch rise such as what's provided by # C45015 would get you within 1-2 inches of level which is perfect.

In addition to the hitch and a trailer wiring harness like # C56231, you'll also need a # PC2 hitch pin and a trailer ball like # 19256 for a 1-7/8 inch or # 19258 for a 2 inch ball.

As a final note, you'll want to make sure that the weight of the boat doesn't exceed the 2000 lb capacity of the hitch or its 200 lb tongue weight capacity.

You can see an install video for the hitch and the trailer wiring harness.
