THE BALL MOUNT OR LET'S SAY STEPPING UP TO THIS CURT SIZE BALL MOUNT PROVIDED GREATER STABILITY, IT WAS A SOLID FIT WITH LITTLE TO NO MOVEMENT, JUST LOVING IT!!!!



by:

I have bought from E trailer before. They have the specific tow rated item I am looking for that I can't find locally.



by:

Ever thing arrived in good shape and was just what I wanted



by:

This is a high quality product that works great for pulling our side-by-side trailer. However, the shank (rectangular tube that inserts into the vehicle receiver) is quite long. This could cause issues if the chains on your trailer are fairly short because it pushes the trailer further back from the vehicle. Other than that, this is a great product.



by:

I really enjoyed the whole process. First time ordering and had no issues. I like how specific the tracking information was presented and the product arrived a day early and undamaged. Will definitely shop again!



by:

etrailer is an excellent source for any trailer hitch towing needs. Greg S. whom took my order was very pleasant to work with and knows his business. I had an email notification within about an hour from placing the order that my part had been shipped and contained the easiest shipping tracking information I have ever used. I ordered the part on 3/28/2019 and our USPS mail man delivered the part on 3/30/2019. You could not ask for any better service than that. The part is quality and finish is excellent. etrailer will be my first choice for any future trailer hitch towing needs.



by:

Arrived quickly and was as described.



by:

Bought this to tow a 7500 lb boat trailer. This ball mount is beefy. The welding and finish are excellent and made in the USA.



by:

I use this draw bar with my 7800 Tritoon Trailer. To date it has worked as designed.



by:

First time ordering from etrailer......great experience. They made sure I got the proper equipment for my towing, and it arrived in 2 days. Excellent quality....I'll be ordering again from them!



by:

Exactly what I needed at a great price. These are also very nicely finished, good looking parts. Only the best from etrailer.



by:

Good product. Trailer sits level. Seems to be good quality. Fast shipping.



by:

Good quality. To note: I have a 1inch lift on my 1500 and the ball point is lower than ideal. Best suited for trucks with a 3 inch lift or more.



by:

Info on site made it easy to select the right product I needed for my application. Exactly what I was looking for. Great build quality.
Product was delivered quickly and in great shape.
Thanks etrailer



by:

Fantastic price and arrived at my doorstep two days after I placed my order. Couldn't be happier.



by:

Perfect for me I know I will never have a failure



by:

Does what it's supposed to and also great for bruising shins. I had a different brand that rusted and lost all paint after a year, wouldn't do that again. This one seems to retain paint better and not get all rusty.



by:

very well made equipment



by:

Works great seems heavier than other brands I have used in the past.



by:

Seems well made with a heavy protective coating. Coating had a few chips, probably due to the ball shipped in the same box and not kept separated. I’ll treat these spots with POR-15.



by:

Heavy duty! Great powder coat.



by:

I just installed it today it appears to be extremely heavy duty and well-made. Time will tell.



by:

Excellent item. High quality, fair pric e.



by:

Arrived on time and looks great on my 2018 Silverado



by:

Products were as advertised and shipment was faster than expected/

  • Compatibility of Curt Trailer Hitch and Additional Towing Accessories for 2016 BMW X1
    I will go down the list of products that you mentioned in terms of their compatibility with each other. The Curt Trailer Hitch Receiver # C13303 referenced in your question is a Class III trailer hitch with a 2 inch receiver opening. It is confirmed to fit your 2016 BMW X1 and will work very well. The Curt Euro Style Drawbar # C45572 that you also referenced is a Class II ball mount designed for 1-1/4 inch receivers. This will not be compatible with the 2 inch receiver on the above...

  • Ball Mount with 4 inch Drop, 2 inch Ball, and 10k Weight Capacity
    I have a similar solution that will work great for you but we don't have exactly what you are looking for with a hitch ball installed as well. So instead the best way to accomplish what you are looking for is with a fixed ball mount part # C45311 which has the 4 inches of drop, 10k capacity, and fits a 2 inch hitch. For a 2 inch ball to then fit this you'd want the # A-90 which also has a 10k capacity and you'd be set.

  • How to Determine Ball Mount Rise or Drop for 2018 Ford Edge
    Thanks for the order of the Draw-Tite Trailer Hitch # 75234 and when we test fit it on a 2018 Ford Edge, you are correct that the distance from the top of the receiver to the ground was 12-1/2". In regards to the height of the Draw-Tite # 36501, when we test fit it on a 2009 Ford Escape the top of its receiver to the ground was 16-3/4", though that's not a height you will want to use to determine the ball mount you'll need. In order to choose the correct ball mount, there are a couple...

  • Shank Length of Curt C45311 Class III Ball Mount
    The distance from the center of the hitch pin hole to the gusset welded onto the Curt # C45311 is 4 inches, as shown in the provided photo. If you're wanting something with a longer shank for additional clearance, I'd recommend the Curt # C45270 which would offer a similar rise/drop but with a shank that's 8 inches long, measured from the center of the hitch pin hole to the closest part of the ball platform. The ball mount is rated for 7500 lbs. I've also provide a photo of this ball...

  • Where to Measure to Determine Correct Rise/Drop for Ball Mount
    Since there aren't any zero rise/drop ball mount options (shockingly) you might verify that your setup was measured in the right spots. You'd want to measure from the bottom of the coupler lip down to the ground when the trailer is level and then from the top of your hitch opening down to the ground. The part # D320 has a drop of 2 inches and comes with the tab needed for friction sway control. This probably would be close enough to what you'd need.

  • What Ball Mount Is Needed for a 4x8 U-Haul Cargo Trailer with a 2013 Hyundai Santa Fe
    The etrailer.com Trailer Hitch Receiver part # E98841 when we installed it on a 2013 Hyundai Santa Fe was 13" from the ground to the top inside edge of the receiver tube. I called U-Haul and they said that the coupler height of the 4x8 cargo trailer is around 16" from the ground to the bottom of the coupler while level therefore you will need to use the Curt Ball Mount for 2" Hitches part # C45311 with the 2" Hitch Ball part # A-90.
