Video Transcript for Curt Ball Mounts - Adjustable Ball Mount - C45902 Review

Today we're going to be taking a look at the Curt Adjustable 2-Ball Mount. The ball mount is going to have the built in hitch ball that's going to hook up your trailer to your tow vehicle. The shank portion, which is this portion right here, slides into the receiving sleeve of your hitch. Then the hitch balls are going to provide the connection points for your trailer coupler. The adjustable height is going to let you tow trailers of different heights and still be able to use the same vehicle. All you have to do is slide the mount up or down along the shank and then secure it in place with the included pins and clips.

Again, it's going to come with two differently sized hitch ball, that's going to let you tow trailers with different coupler sizes. To switch between the balls, all you have to do is remove the pins and clip. Rotate the balls, and then reinsert it and to the channel, and then secure it with the included pins and clips. The unit will adjust in increments of 1". This is a channel style mount, so it's going to let you attach other channel mount accessories. It's also going to feature an anti-rattle design that's going to help reduce towing noise.

It's going to come with this bolt right here, and then thread in to one of the three holes along the back. Then as you tighten that down with the included tool, it's going to apply a pressure to the back of this mount. Which is going to allow that rattle free design, that nice tight secure hold. Which again is going to help reduce towing noise. The unit's made from a heavy duty steel construction.

Here on the actual mount, it's going to feature a durable car by powder coat finish. Then on the hitch balls, we're looking at a yellow zinc finish. Both finishes are really going to help resist rust and corrosion, and make sure that the unit last a long time. It does come with the included hitch pin and clip to get it secure inside your hitch. You can see back here on the shank, its got two different holes. Both same size, just different placements that way you would install in this, you can choose whatever one is going to work best for your application, or give you the most clearance that you need for your particular vehicle.

This is designed for a 2 1/2" x 2 1/2" trailer hitch receiver. It's going to offer a gross towing weight when using the 2" ball of 10,000 pounds, and 20,000 pounds when using the 2 5/16" ball. The tongue weight on the unit is rated at 2,000 pounds. A few measurements to go over with real quick. If we we're to take a measurement from the center of the hitch pin hole to the center of the hitch balls, measuring from this closest hole right here. We can see that that's going to give us a measurement of about 10 3/8" and then to the center of that rear pinhole, 11 3/8" of an inch. The distance that we have from the center of the hitch pinhole to the back of the shank, measuring from this one right here. That's going to give us a measurement of about 3 1/4". Then from this one, that's going to be about 4 1/4". You can use this system neither the drop or the rise position. The rise position with the mount at the highest setting is going to give you a maximum rise of 6". Your rise measurement is taken from the inside top edge of the receiver tube of your hitch to the top of the ball platform. If you we're to use this in the drop position with the mount at the lowest setting, it will give you a maximum drop of 5 1/4". The pinholes are going to have a diameter of 5/8". That's the size of the pinholes here on the channel mount and the pinholes to secure inside your hitch. The width that we have right here of the channel, inside edge to inside edge, that's going to measure about 3". A few more measurements that I want to mention real quick. The distance that we have from the center of the hitch pinholes to the back of this upright portion right here. From this pinhole, that's going to give us a measurement of about 3", from this pinhole that's going to be about 4". That measurement is helpful to know when using the mount in the rise position because you want to make sure you have enough room for the rear most part of your vehicle to this point here. Making sure that it doesn't interfere if you want to use this in the rise position. Then you can see as we go up the mount, that measurement would increase. Real quick, I just want to go ahead and show you how to change between the differently size hitch balls. Again, to do so, you would simply just remove the clips. Remove the pins. Take this unit out and then rotate it, then to adjust the height, you can simple just slide it up and down your shank. Then you would resecure it with the clips on the other side. Really nice design, again, very strong and durable design. The channel and the portion of its slides into your hitch is going to be made from a solid steel and again they're going to have that nice black powder coat finish and zinc finish to resist rust and corrosion. That's going to do it for today's look at the Curt Adjustable 2-Ball Mount.

Curt Adjustable 2-Ball Mount - 2-1/2" Hitch - 6" Drop, 5-1/4" Rise - 20K - C45902

Average Customer Rating:  4.9 out of 5 stars   (105 Customer Reviews)

This heavy-duty steel, adjustable ball mount lets you tow up to 10,000 lbs with the 2" ball or 20,000 lbs with the 2-5/16" ball. Can be used in 6" drop or 5-1/4" rise positions. Fits 2-1/2" x 2-1/2" hitch receivers.

This hitch is to be used on my 2017 F-350 Super Duty SRW Super Cab which has a conventional tow limit because of the single rear wheels and short 148" wheelbase of 15,000lbs. The Curt 20,000lb rating exceeds the truck's rating so it will never be overtaxed. It is a nicely finished quality product with only one niggle. There are 3 hole positions for the anti-rattle bolt. the anti-rattle bolt is too short to reach the arched portion of the sliding ball assembly so if you move the ball assembly to some positions the anti-rattle feature would not work. I will find a 1" longer bolt to remedy this situation but for the price, Curt should have supplied a longer bolt. 420534

Excellent product. Durable and heavy duty. the only "issue" I'd say I have is the quality of the finish and the rating sticker. trivial but the finish has started to either fade all around the mount and or rust around where the mount is inserted into the receiver. But I wouldn't trade it for anything when comparing adjustable dual ball mounts. 697971

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. 318960

Exactly what I needed. Purchased a new 24 ft cargo trailer and I tow with a 2016 F-350 dually. This hitch gives me variability so I can make adjustments based on weight in the trailer and air bags on the truck. Great product and great service. Arrived exactly when they said it would. Thank you, etrailer. 496279

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! 666461

The transaction was easy and the delivery was fast! I haven't put the hitch on my truck yet, but I'm not expecting ANY problems! 562419



- C45902
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. 269330



- C45902
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. 490920


Comments

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 # RH5-XL

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.

SO I JUST PURCHASE A BRAND NEW 2018 F250 SD. I AUTOMATICALLY KNEW I NEEDED TO UPGRADE MY HITCH SETUP FOR THE 2.5 RECEIVER. WELL COMING FROM STD HITCH TO THIS ONE IS BIG JUMP. YOU CAN FEEL HOW HEAVY AND HOW STRONG THIS HITCH FEELS RIGHT AWAY. THE ADJUSTMENT ARE ENDLESS IF YOU HAVE MULTIPLE TRAILERS. IF YOU GONNA TOW SOMETHING HEAVY DONT LOOK ANYWHERE ELSE, THIS HITCH WONT LET YOU DOWN. I DID BUY A HITCH PIN(RED HANDLE) FROM HARBOR FREIGHT FOR SECURITY PURPOSE. I WANTED TO ADD A PADLOCK DO THE PIN. A+++++ 491288

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. 546076

Received my Curt Adjustable 2-Ball Mount in just a few short days after my online purchase... It was very well packaged, undamaged and very easy to assemble. Very adjustable, for my 2017 Ram Cummins 2500 CCSB truck. I have already towed a 13,000+ lb flatbed with a skidsteer and extra drilling attachments. The adjustable hitch let me position the trailer PERFECT for a heavy tow. This weekend, I brought home a 30ft travel trailer, and I was able to flip the ball, from the 2" to the 2 5/16" ball in only a couple of minutes. This is a very heavy duty hitch and I look forward to many miles of smiles as I enjoy traveling across America, with the RIGHT hitch for my rig. THANK YOU etrailer.com This was my second purchase with them, first was a Class V+ XD receiver for my deuce and a half, fit perfect... and recently a set of 5 tires for my travel trailer in a hard to find D load rated 14 inch size. I would very highly recommend etrailer for future purchases. 459706

Ask the Experts about this Curt Ball Mounts

Do you have a question about this Ball Mount?


  • Comparing Flash Solid Steel HD Adjustable 2-Ball Mount and Curt Channel Adjustable 2-Ball Mount
  • The weight of the Flash Solid Steel HD Adjustable 2-Ball Mount # FA49-00-5625 that you referenced is 37 lbs, and the weight of the Curt # C45902 is 36 lbs. 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. I'd say the edge goes to the Curt though since it has...

  • 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,...

  • 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.

  • 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.

  • 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. We have 1 ball mount for 3 inch hitch receiver openings; # RP38180. It has a 2 inch and 2-5/16 inch ball. 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. If you mean capacity then the highest capacity 2-1/2 inch ball mount...

  • Availability of Locking Pin For Curt # C45902 Adjustable Ball Mount

  • 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...

  • Adjustable Ball Mount for 2-1/2 Inch Hitches made in the USA
  • Curt trailer hitches are manufactured in the USA but not the supplemental parts like ball mount # C45902. For one that is made in the USA and is similar I recommend # BWTS20037B. But it maxes out at 14.5K with the 2-5/16 inch ball. The Curt model # C45902 is the only option we have in an adjustable ball mount for 2-1/2 inch hitches that can reach 20K. For a few dollars more you can get the tri-ball model # BWTS20048B. I have linked a video of it for you.

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...

  • 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.

  • 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.

  • Recommended Locks For Curt Adjustable 2-Ball Mount For 2-1/2 Inch Receivers
  • We can take care of securing the Curt Adjustable 2-Ball Mount, part # C45902. We have the # C23556 kit that includes a straight locking pin for the ball mount that will work on the # C45902. The additional pin included will only work with a 2-inch receiver and will not work with the 2-1/2 inch shank on the # C45902. I called my contact at Curt and they told me that this will be available in the future but is not available now. We also offer locks that will work with a 2-1/2 inch...

  • 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...

  • Adjustable 20,000 lb Ball Mount Option with Silver Colored Hitch Ball
  • I have a possible solution for you, but Curt does not offer a silver two ball attachment for the Curt Adjustable Ball Mount # C45902. 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. This will be good if you are in a cold climate with salt on the roads. A hitch lock is also available for this ball mount, # FA86-00-3685. If you don't need...

  • 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...

  • We do have some sway control kits that can be used with the 20K Curt Adjustable 2-Ball Mount # C45902 for a 2-1/2" trailer hitch, but they are electronic sway controls as there are no mechanical sway controls that will fit with that specific ball mount.

  • The Ford 2-1/2 inch trailer hitch on your 2005 F-350 does have a different corner radius then what 2-1/2 inch accessories have so there have been some fit issues. But the Curt products such as adjustable ball mount # C45902 didn't seem to be a problem. In the event that it does have a hard time easily fitting you can sand away some of the powder coat on the ball mount shank and it will fit better.

  • Recommended Steel Adjustable Ball Mount for a 2-1/2
  • For a Steel Adjustable Ball Mount, I recommend the Curt Adjustable 2 Ball Mount for 2-1/2" hitches # C45902. This ball mount will fit your 2-1/2" hitch and has a 6" drop or 5-1/4" rise. This ball mount is made from durable heavy-duty steel and has an anti-rattle design to help reduce towing noise. You may want to consider an aluminum ball mount over steel because it is lighter and more resistant to rust. For an aluminum ball mount, I recommend the Weigh Safe Adjustable 2-Ball Mount #...

  • How To Add a Pintle Hook to the Curt Adjustable 2-Ball Mount

I would also recommend you use the Curt Lock Set for Adjustable Channel-Style Mounts part # C23556 on this setup as it will be a bit more valuable than the standard hitch ball. The Curt Pintle Hook with 2-5/16" Hitch Ball part # C45922 is not offered without the hitch ball attached.
