I have had this hitch for a year and it has towed trailers all over the northeast. It is still in great shape and works great.



by:

I have been completely satisfied with this product. Very durable, solid beyond my expectations. Whether towing 1/2 ton or 6 tons I have no concerns that the trailer and load aren't safe and secure. Would purchase again but won't need to as this hitch was built to last.



by:

First of all, ETRAILER is a great company in my opinion. Their selection, prices and customer service are all great.

This hitch is stout! I'm the type that I'd rather have more capability than what I may actually use. For what I will use this for, I'm 100% sure it will be way more than I'll ever need but I'm also confident that I would not have any issues using it regularly at it's maximum capability. The construction of it is top notch and I'd be willing to bet it can do more than what it's rated for.

I will definitely be ordering the 20K Pintle that works with this as well as a Curt 5th Wheel and Gooseneck. Thank you ETRAILER and thank you CURT for amazing service and and amazing product.



by:

Hitch is very heavy duty which is nice. Think some more engineering could go into it so you don’t have to use the Allen to snug hitch to keep from rattling. I ended up purchasing the rubber inserts. Definitely recommend if towing heavy trailers.



by:

What is there to say about a perfect hitch like this one? Why haven't you got it yet would be it. I have a 2015 Dodge Ram 2500 and it went low enough for any trailer I pulled. Performed perfectly at pulling any trailer, of any size, of any weight. Still use it today (2023) It does have a locking bolt if you don't like hitch ball rattle. But you don't have to use it and it works fine without it. The hitch rattle doesn't bother me. I guess the only thing I would have liked is if it had come with another drop hitch with 1 7/8 ball on one side. And maybe a hook or a hole for a clevis on the other side.



by:

Super strong, not much noise. Have it on a ram 2500 on 35” tire with stock suspension and it goes low enough for my 4x8 trailer and tall enough for my dump trailer and flatbed



by:

Just what I needed for the Ram 2500, so I can pull smaller trailers and keep them level.



by:

Great product. I bought one for myself a year ago and ordered this one for a coworker.



by:

Very well built. I've had it for one year and it's exactly what I needed. Heavy duty towing capabilities, adjustable and two ball sizes. What more could you ask for?

Supreme

10/3/2022

After one year it has held up fantastically. Very little to no rust showing. It has been very durable through the heavy snow and salt life after a winter season. I still would recommend this to anyone.



by:

Overall quality looks good . Powder coating is less than adequate 1 day in the rain it has rust on it

So sorry to hear of any inconvenience with your order. Since this product is covered by a 1-year limited warranty, I have forwarded your review to our customer service department for direct follow-up with you.



by:

Very strong and durable hitch. Elevation and dropping is very convenient.

2 big issues with his hitch.

1) does not have an option to buy a 1 7/8 ball.
2) even with a pin lock on the hitch, the balls can still be stolen with its design. If the balls are stolen they can not be easily replaced or cheaply.

Overall, does the job, but once it is stolen, I’ll be buying something better theft protection.

As with any ball mount, it is recommended to remove it from the vehicle when it is not being used. This will protect it against theft and corrosion. Some States actually mandate that a ball mount be removed when not towing. If removing the ball mount is not feasible, a hitch lock # e98881 can be used in place of one of the pins that hold the ball in place.

Jared

3/30/2019

Hitch hasn’t been stolen. Easy hook up. Pulls 12k with ease. Rust build up is a little disappointing, but still have plenty of life in it. Hitch has saved my bumper from damage several times.



by:

I ordered the adjustable ball mount and it showed up in two days and in perfect shape. Etrailer has always delivered parts very timely. Thanks.



by:

I have dealt with these folks before, timely shipment, product received as advertised



by:

The hitch arrived quickly and as expected. Normally a hitch that weighs as much as this one (37.5lbs shipped) is hard to order online due to the weight of the item but etrailer really made it easy. The interaction with the folks from etrailer was perfect. They were detailed in their email and made every effort to make this a personal experience.



by:

Fast shipping from etrailer. Very heavy duty unit and perfect for my 2020 Silverado 2500HD. I needed an adjustable drop hitch and this unit works perfectly between different trailers that I tow.

Ron

12/17/2021

Had the hitch a year and still love it. When not in use I remove the hitch from receiver and store it away for fear of theft.



by:

The product is everything they said it was and more, the adjustment capabilities are great along with the ability to extend the receiver. I plan to pull a 26 foot car trailer at about 12,000 pounds loaded. The service and concern as always was excellent. I highly recommend this product and certainly etrailer.



by:

Always a pleasure doing business with etrailer. Product came with free shipping in 3 days! What more could you ask for?



by:

This is the quickest and easiest ball mount I have ever seen or used. Just by pulling 2 pins you can easily adjust the ball height and size in seconds. Very pleased with Curt product. Etrailer.com has great products and great service.



by:

The shank has a lot of play , up down .. side to side
Slops around while towing
When you brake the ball will shift up and down causing it to be uncomfortable

3/28/2022

I do have a solution for you. I recommend adding an anti-rattle device such as part # BX88312 to help take out movement in the hitch receiver.



by:

Strong as on ox. Love it. Very easy to adjust and flip. The real deal!

Teamtrailrat

9/4/2023

This dude is the beast! Strong as an ox. Tremendous vertical range by flipping vertically. Appreciate rubber bushings on back of the 2 ball mount that absorb shock against the gusset. I tow 3 types trailers all different heights. Adjusts quick n easy. Love it.



by:

Very well made and heavy duty.



by:

Heavy, simple, solid. The clever anti-rattle feature is nice too; Great ball mount!



by:

This is a heavy duty hitch set up. I have only used it a few times but I know what ever I hook up to. it will get the job done. I have towed a full size suv and a large heavy duty trailer with no problems. This hitch should give a life time of service and then some. If your looking for a heavy duty hitch set up. This is the one you want. Only thing negative is it needs to be able to accommodate a1 7/8” ball. Other than that it’s perfect.
Thanks etrailer for having outstanding products like this to offer your customers.

Chuck D.

1/12/2021

Still looks good and no issues. Does what it was made for. You won’t go wrong with this hitch.



by:

Easy to adjust and strongly built

Wayne

1/2/2021

No problems at all.



by:

Very pleased with the product quality. The hitch must have been updated since the video and still images were taken. The manual “anti-rattle” design is gone. Replaced by a rubber plug, which I can only assume will work just as well (?). Shipping time was minimal, etrailer has always delivered well.

  • Fit of Curt # C45920 Channel Mount Pintle on Curt # C45900 Adjustable Ball Mount
    The Curt Channel Mounted Forged pintle/trailer ball will indeed fit in the 3 inch wide channel of the # C45900 or the # C45920 ball mount. I've confirmed this with my Curt representative.

  • Anti-Rattle Device for Curt Adjustable Ball Mount # C45902 on a 2013 Ram 3500
    There are 3 places of possible movement for Curt adjustable ball mount # C45902: the 2 pins that hold the ball to the shank and between the shank and the hitch itself. If you have that screw at the ball part nice and tight then you are probably getting movement at the hitch receiver. To keep the screw from coming loose a lock washer could be used. You can reduce or even eliminate movement at the hitch using an anti-rattle device such as # RSCP. With adjustable ball mounts like this there...

  • Class V Trailer Hitch For A 2022 Ford F-250 Super Duty
    Yes, the Curt Trailer Hitch Receiver # C15802 does fit your 2022 Ford F-250 Super Duty. This is a class V hitch with a gross towing weight of 20,000lbs and a maximum tongue weight capacity of 2,700lbs. If you need a ball mount, a great option is the Curt Adjustable 2-Ball Mount # C45902. This is an adjustable ball mount capable of handling 20,000lbs when using the 2-5/16" ball.

  • Recommended Trailer Hitch Receiver For 1998 Chevy K3500
    For a 1998 Chevrolet K Series 3500 Pickup, I recommend the Draw-Tite Ultra Frame Trailer Hitch Receiver Class IV - 2" # 41901. This is an extremely sturdy hitch that is easy to install. It will fit a standard or step bumper. For a roll-pan bumper, use # 41522. For your wiring, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118315 to get a 4 way connection. Then you will want to add the # ETBC7 to get your 7 way connection along with the circuit breakers,...

  • 3-Ball Adjustable Ball Mount for a 2-1/2 Inch Trailer Hitch Receiver
    Since you use all three common ball sizes regularly I recommend an adjustable ball mount that comes with all three since there isn't a 1-7/8 and 2 inch combo for # C45902. There are several options for a 2-1/2 inch hitch such as # BWTS20049B. I have included a link to all of the options with 3 balls that fit 2-1/2 inch hitches.

  • Do I Still Need a Ball Mount with My Weight Distribution Hitch
    It sounds like you're trying to add a weight distribution hitch to your trailer, so you don't actually need to use the Curt # C45902 with it. In most cases you can get a weight distribution hitch that comes with a shank included, like the Curt Tru-Track # C17501 which is designed for trailers with a tongue weight of 1000-lbs and 1500-lbs. There are some that do not come with the shank included, so you'll want to choose one that does where possible as long as you don't need one with a...

    The highest rated adjustable ball mount we offer that is designed to fit a 2-1/2 inch hitch like the Class V hitch of your 2016 Ram 2500 is the Curt Ball Mount part # C45902 which has a 20k capacity when you use the 2-5/16 inch hitch ball and a 10k capacity with the 2 inch hitch ball.

  • Best Trailer Hitch for a 2008 GMC Sierra 2500
    The best trailer hitch for your 2008 GMC Sierra 2500 will vary depending on what you're going to use it for and possibly whether you have an 8 ft. or 6-1/2 ft. bed. If you need to haul a lot of weight I would suggest the Curt Class V CD 2-1/2" # C15703. This will get the most out of your truck for your dollar and will work with either length of truck beds. The Curt Class III # 13208 will also work with both bed lengths and would be more appropriate if you're not hauling as much weight. I...

  • Recommended Adjustable Ball Mount for 2-1/2 Inch Receiver and 15,000 lb Trailer
    Based on your question, I assume you have the 2-1/2 inch trailer hitch receiver. There are many options available to assist with your desired towing weight, but there is one that I recommend above the others for ease of use and function at that capacity. I recommend the Curt Adjustable 2-Ball Mount # C45902. This ball mount accommodates up to a 5-1/4 inch rise or up to a 6 inch drop. It adjusts in 1 inch increments and has both a 2 inch and 2-5/16 inch ball. To secure your investment,...

  • Locking Hitch Pin Set For Adjustable Ball Mount Requiring 4-1/2" Inner Span on 2 Pins
    It sounds like the InfiniteRule Locking Pins # IR39FR will be the best option for your adjustable ball mount. This kit includes two 4-5/8" inner span locking pins and one 3-1/8" inner span locking pin for securing the hitch to the receiver. These 3 locks are keyed alike and have a 5/8" diameter. For the Curt Ball Mount # C45902 you were looking at Curt offers their Lock Set # C23556 but the single long pin they offer is only 4-1/4" inner span.

  • Is Locking Pin Kit for Curt Ball Mounts C45902 and C45900 The Same
    The channel dimensions are the same between the part # C45900 and # C45902 so the locking pins that fit one would also fit the other. For that you would be referring to part # C23556.

Same capacity at 20,000 lbs, both fit 2-1/2 inch hitches, both can do same amount of drop at 6 inches, both are highly reviewed by our customers, and both have very similar prices.

  • Why Do Rear Tires on Tandem Horse Trailer Run Hotter Than Those on Front Axle
    If the tires on the rear axle of your tandem axle horse trailer are running hotter than those on the front axle, this could be due to several possible causes. One of these causes you mentioned; the trailer not being level when hitched. If the trailer rides nose-high this tends to place more of the trailer's load onto the rear axle. This could easily cause those rear tires to run hotter. All trailers tow best when they are level so if you need to switch ball mounts you can choose one with...
