Expert Reply:

This will depend on the hitch used and the height of the trailer coupler. You want the trailer to be as level as possible. We have a page on calculating hitch height and coupler height to help you find what ball mount would work best.

Most light duty trailers are 16-17 inches in coupler height, so we recommend ball mounts on the hitch pages that will give that particular vehicle 16-17 inches on the ball mount. The ball mount that provides 16-17 inches height for a 2008 Hyundai Entourage is part # 2753.

I have a fairly steep driveway. Before I purchase a trailer I would like to figure parameters for when my hitch might bottom out. I suspect it has to do with the angle of the driveway and length of trailer from coupler to axle? An illustration on what to find to figure out would be ideal.

This is a difficult question to answer because of all the variables involved. There isn't really a set formula or diagram you can use for it. If bottoming out is a big concern, your best route will be to actually mock up a trailer setup with your tow vehicle on the driveway to see where it bottoms out, and what needs to be changed to prevent it. The driveway angle, actual coupler height when hooked up (the rear of your vehicle will likely sag a bit upon hookup), angle you actually come up or down the driveway, etc will all factor into play.

@ChrisR I am in a similar situation and have made a pyramid shoring set that will decrease the angle, it takes an extra step to place them in the low spot but works fine for raising the trailer axle 4''

Curt recommends the use of 250 ft/lbs of torque when tightening the nuts of their hitch balls with a 1 inch diameter shank like the part #C40034 that you referenced. The general rule is for a 3/4" shank tighten to 150 ft/lbs For a 1" shank…

We don't have a combo of the Curt Hitch Ball #C40008 and Curt Ball Mount #C45340. The ball mount is extremely heavy-duty, rated up to 17,000 pounds. I think it's safe to assume you don't have a torque wrench rated up to 450 foot pounds…

The only difference between 7-Way Utility and 7-Way RV is the color of the wires. The pin outs are the exact same so either would work just fine with the other. If you check out the picture I attached you'll see that the functions are all the…

Both rise and drop are measured from the top of the drawbar's shank to the top of the hitch ball platform. The length of the drawbar is measured from the center of the hitch pin hole to the center of the hitch ball hole. I've added a link to…

Answer 7

The ideal height will actually have to do with how tall the coupler of the trailer is from the ground. The Draw-Tite #76020 will sit at 13 1/2 inches from the ground to the top of the hitch when installed on a 2016 Mazda CX-9. From what I could find…

Many of the ball mounts we offer that we offer that fit 2 inch receivers like part #2753 which has a 2-3/4 inch rise or 4 inch drop, that are designed to be able to use in a rise or drop position by simply turning it upside down, without losing any…

Answer 10

I'd say an inch would be a good safe amount of clearance if the bike rack is one of the more stable options out there, but if it's a rack that has a bit more movement to it the safer measurement might be more like 1-1/2 inch to 2 inch.…

There isn't a specific distance you want to have between the bumper of a vehicle and the hitch ball, but in general you'll want more than an inch. This will give you additional leeway when hitching up the trailer so that you don't slam…
