I've used this hitch before on a 3500 Dodge Cummins. Unfortunately I sold the truck and forgot to remove my hitch. So I purchased it again for a 3500 Chevy Silverado. I had this hitch for several years and pulled a $14,000 lb capacity tandem axle trailer with it . I was then able to adjust it for pulling a boat or my smaller trailer when needed. Very pleased with the product and quality



by:

This is a great very HD hitch. with a 20K tow rating I feel secure hauling heavy loads. The adjustable height allow you to have your trailer level like it is designed to be.



by:

The product was well described on the web site. The truck matching worked great and was easy to use.
This hitch was very easy to order and the price was good.
The delivery date was correct, it was easy to follow with the information provided.
The hitch was as advertised, easy to install and easy to use.
Great Job!

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:

very easily adjustable for how sturdy it is



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:

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:

Great Product, Great Service



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:

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



by:

I have used this hitch for a couple years and have been impressed with it. Also shipping was fast and on time.



by:

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



by:

Arrived on time and in good condition. Works great.



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.

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:

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.

No problems at all.

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:

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.

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.

OVER ALL WAS HAPPY WITH WHAT I GOT. THERE IS A COUPLE THINGS THAT I DID NOT LIKE. 1 THE ALLEN HEAD WHEN YOU TIGHTEN IT UP SO THAT SOME CAN'T STEAL IT I WILL MUSHROOM OUT THE END AND IS HART TO GET OUT AND TO RE START IN A NEW HOLE, I DID NOT TIGHTEN IT THAT HARD.2 THE GOLD COLOR OR WHAT EVER IS ALL GO AWAY AND THE BALL IS A STEEL COLOR, NOT SEEN RUST YET? BUT WITH THAT BEING SAID I LIKE THE HITCH AND WORKS WELL.AND WOULD BUY ANOTHER ONE IF NEEDED.OVER BETTER THAN GOOD. SAM

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.

  • Will Curt Lock Set Fit Curt Adjustable 2-Ball Mount for 2" and 2-1/2" Hitches
    Yes, the Curt Lock Set # C23556 will work with both the # C45900 and # C45902 meaning the 2-1/2" hitch won't be a problem. The pair of locks comes keyed alike but there is no option to match the keys between the sets of locks.

  • 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.

  • Availability of Locking Pin For Curt # C45902 Adjustable Ball Mount
    There is indeed a locking hitch pin set, part # C23556. This part number includes two locks, one hitch pin lock and one locking pin that would replace one the retaining pins that keeps the ball assembly in place. The locks are keyed alike.

  • Availability of 20k Adjustable Ball Mount that Can Adapt to Pintle Hook
    Since there isn't a pintle adapter for the Fastway adjustable ball mount part # FA49-00-5625 that has a 20k capacity your best option that's similar is the Curt Adjustable Ball Mount # C45902 which also has a 20k capacity. To convert this to a pintle you'd need the # C45922.

  • Can Anti-Rattle Rubber Insert be Used for 20K Curt Adjustable Shank for 2-1/2 inch Hitch Receiver
    Yes it will! The Rubber Bumper # C45921 is a direct replacement for the Curt Adjustable Ball Mount # C45900 but the only differences between the shank that comes with that system and the Replacement Shank # C45917 that you referenced is the weight capacity and the size of the shank that fits into the hitch receiver. The ball mount kit # C45902 that the larger shank is a replacement for does come with an anti-rattle bolt that installs in one of those holes at the back-side but we have a...

    Yes, you will be able to use the Curt Adjustable 2-Ball Mount # C45902 with your Rock Tamers on your 2012 Ram 3500. The Curt Ball Mount has two hitch pin holes so use whichever one that leaves a 1 inch gap between your hitch collar and the adjustable part of the Curt ball mount so your can properly mound your Rock Tamers.

  • Comparing Curt and Flash Adjustable 20,000LB 2-Ball Mount Hitches
    The Curt Adjustable 2-Ball Mount # C45902 is manufactured overseas.

  • Is there a Ball Mount Larger than a Class V 2-1/2 Inch
    If your hitch receiver opening is larger than 2-1/2 inches then the next step up is a 3 inch if you are talking about physical size and not capacity. The 3 inch ball mount you need is # 40701 if this is the case. The hitch ball to fit is # C40085. This is not a common size though so I do recommend verifying the size of the receiver opening on the hitch. I have also included a link to our ball mount main page.

  • 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...

    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.

  • Can the Ark Articulating Coupler Be Used with an Adjustable Channel Mounting Ball Mount
    We haven't tested using an Ark Articulating Coupler # AR44FR with a Curt Adjustable ball mount like the # C45902 and I don't think this is going to work because of the limited clearance from the hitch ball to the channel. You'll instead want to use a ball mount with a drop like the # C45338 specifically for towing with the AR44FR, since it will allow the coupler to move freely. I've linked an article on how to properly measure for a drop/rise ball mount to this answer in case you're not...

One possible solution for you is the Fastway E Series HD Adjustable 18K Ball Mount # FA42-00-2625. A nice feature about the Fastway ball mount is the corrosion resistant aluminum construction.

  • Pintle Hitch Ball Mount Rated for Over 20,000 Pounds for 2-1/2 Inch Trailer Hitch
    There isn't a pintle adapter for ball mount # C45902 rated for 21,000 pounds but I may have a solution for you. What you could do is use ball mount plate # 337PM25812 with Convert-A-Ball pintle hook combo # PH1. When used as a pintle hitch the capacity will be 20,000 pounds. Or for a pintle/ball combo we have # C48012 rated for 20,000 pounds but it is not adjustable. I know that falls just under the 21,000 pounds you are looking for but to go above that you would need a 3 inch hitch.

    There are replacement ball mount platforms available for each of the Curt channel style adjustable ball mounts. If you have the Curt Channel Style Adjustable Ballmount - 2" & 2-5/16" Balls # C45900 then you would want Replacement 2" and 2-5/16" Dual-Sided Hitch Ball # C45912. Should you have the Curt Adjustable 2-Ball Mount - 2-1/2" Hitch # C45902 you'd be looking for Replacement 2" and 2-5/16" Dual-Sided Ball for Curt 2-1/2" Adjustable Ball Mount # C45923.

So in that regard they are essentially the same. They really are quite a bit alike in most ways. 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.

    The Replacement Shank # C45917 is for the Curt Adjustable 2-Ball Channel Mount # C45902 which has a 5-1/4" rise/6" drop. I reached out to Curt and my contact said that at this time (July 2020) there is no replacement shank for the Curt Adjustable 2-Ball Channel Mount # C45927 so you'll have to pick up the entire ball mount to use this shank.

  • Locking Pins for Curt Adjustable Ball Mount # C45902
    For Curt adjustable ball mount # C45902 the locking pin set is # C23556. The pins don't have an official capacity but technically 5/8 inch diameter solid steel is going to have a capacity much higher than the hitch or vehicle. The hitch pin has a useable span of 3-1/4 inches which should be long enough for the outer width of your 2-1/2 inch hitch but it never hurts to measure to be sure.

  • 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...
