I have a 2015 Ford F-250 with the factory 2.5" receiver hitch. This drop ball mount fits into the factory receiver well, contrary to the product warning. It is also extremely beefy, you will not be disappointed! Photo fitment proof!


Very Strong ball mount. My wive (its her truck), towed 7000# of horse, tack and trailer last saturday. I know this ball mount is overkill but it is easier than using a 2" with the receiver adapter. Also this way if we have to tow something real heavy we already have the ball mount for it.



Looks like you tow horse trailer with Ram 2500. I just purchased one for towing a horse trailer and am trying to figure out if I need a 4 or 5 inch . Looks like 5 inches works for you.

Patrick B.


The drop size depends not just on the truck but the height of the trailer as well. There is a real quick way to figure out exactly what size drop you need. You'll just need to take one measurement on the truck and one on the trailer. Check out the link one of our FAQ articles on slecting a ball mount.


Top notch super heavy duty solid Class V 18000# 2 1/2" hitch with 5" drop. Has some weight, but easy to heft with recessed sides. Married this with a 2 5/16" Brophy raw hitch ball. This is overkill for a 7,000# GVWR trailer being pulled frequently by a 2014 Chevy Silverado 3500HD 4X4 Crew dually with 2.5" stock receiver. Has also occasionally pulled several 6,000# wagons to the elevator. Have no major complaints, but there is a slight variant in size of about 1/16" mounted in the 2.5" receiver so there is very light feel when pulling empty. The 5" drop seems to work the best. This is the second hitch purchased for quick change out. Couldn't be more satisfied.


Fits the 2013 Ford F350 with the heavy duty receiver factory option.


Great customer service and quick shipping. Ricky S. called when my product was backordered and took care of it immediately. Most places don't care that much. You have my business next time and I'll definitely recommend your business to others looking for towing products. Thanks for the great experience!


This is a stout 18000 pound 2 1/2" hitch with 5" drop. Fit perfect iin my 2012 Silverdo 2500HD hitch. The recess on each side helps you carry it in your hand comfortably. Don't forget to get an extra long locking hitch pin for 2 1/2" ball bounts with key lock to keep it from being stolen. I married it up with a 12000 pound 1 1/4" thick, 2 5/16" ball with a 2 3/4" shank.

have 2008 ford f350 super,,, dually.? will it fit

Patrick B.


Ford uses a slightly different radius in the corners of their 2-1/2 inch receivers. That radius will not allow this ball mount to fit. If it is an aftermarket 2-1/2 inch hitch, you should be fine. But the OEM 2-1/2 from Ford will not work.


etrailer puy me on the road ,the help excellent,I rate etrailer A++++


I buy items from etrailer a lot and I have yet had an issue with any of my purchases. This ball mount fits perfectly in my hitch receiver and allows me plenty of weight capacity left. No rattle, fits firm and the drop and rise makes towing any trailer easy.


Etrailer has been great to work with. Usually the lowest price and good service. The hitch is made in china, but is backed by Reese so should be trustworthy. I will pull a 14K equipment trailer with my 1 ton ram. Glad my truck came with a class V hitch. I like the extra capacity of the 2.5" hitch!


These hitches are solid. I have had 1 of these for about 8 years and it has taken some abuse with out failure. Liked it so much when my dad bought i new truck we got one for his too. Best hitch on the market if your not looking for adjustable height.


Tough piece of hardware, fits well into both of my 2.5" receivers, no rattling. Don't drop it on your foot, must be 20#.


I have ordered from etrailer several times and had nothing but GREAT service! This last order was over the top on service and delivery, ordered at 3:48 one afternoon and had my Reese Titan Ball Mount the next day! Outstanding! Thanks etrailer, great teamwork!!


great Trailer ball hitch. made extremely well. Strongest ball hitch I could find with a 5 inch drop.
Thank you for the quick shipping


My hitch came quickly , Staff at etrailer could not have been more helpful.

Dave B.


Products are top notch.Service Speed iof etrailer is outstanding!Thank You


Ball mount is as good as advertised. Will definitely be doing business with etrailer again. I received item sooner than expected thanks to the up grade they gave me on shipping at no extra cost.


Great, heavy duty hitch. Fit into receiver very well. Made this hitch the same height as on my other truck.


Bought the forged class V ball mount and returned the just purchased class IV after buying a new truck and rear end was higher than last one so had to go to a 5" drop. Phone support was great and return was easy with label sent to me via email. Thanks for your help.


This is the second Mount I purchase. First one was a different drop size and I needed something longer for the new trailer. I loved the first one so much that there was no reason to change. These are built very strong and I have used it several times hauling very heavy loads on very bad roads. Works as it should .


I have purchased 3 of the titan ball mounts and they all perform as expected. Great product and a great price!


Super heavy duty, should outlast a few trucks.


I needed this to pull a heavy trailer thru several states. It performed flawlessly. I would recommend this for any heavy duty hauling in its class.


Items arrived ahead of schedule in great shape; fit my 2014 RAM 2500 perfectly.


Just what I needed. Extremely well made. Fits perfect. Best place for hitch everything.


Excellent draw bar, and the service at etrailer is outstanding...


Great hitch for heavy loads. Good workmanship and nice corrosion resistant finish.

Tim M.


Use the Ball Mount often. It has been great. It fits the new F-250 reciever and will tow anything that I hook to it.

  • Reese Ball Mount with Black Powder Coat Finish
    The Reese Ball Mount - 3-1/2" Rise, 5" Drop - 10" Long - 18,000 lbs # RP45323 does have a gloss black powder coat finish over an autophoretic coating or "A-coat". This ensures the heat resistant metal is able to be protected from corrosion and wear.

  • How to Determine Tongue Weight of an 18,000 Pound Trailer
    Tongue weight is typically 10 to 15 percent of the gross trailer weight. However there are several trailers that do not follow this rule; such as toy haulers as one example, which can be as much as 20 percent or so of the gross trailer weight. If your trailer weighs 18,000 pounds when loaded and ready to tow then 10 to 15 percent would be 1,800 to 2,700 pounds. If your tongue weight is actually 6,000 pounds then that would mean it is about 33 percent of the gross trailer weight. This...

    If you have the Class 5 hitch on your F-450 and the inside measurement of your hitch opening is 2-1/2 x 2-1/2 inches, then this ball mount will work in your truck's receiver hitch. The hitch ball you selected has the proper 1-1/4 inch size shank to fit the RP45323 ball mount. If you have a 2 by 2 inch receiver then you could use ball mount DTBM5400 (see link below), up to 14,000 pounds and the same ball for your towing needs.

  • Fit of Reese Titan 2½ Inch Ball Mount on OEM Class V Receiver of 2013 Ford Super Duty
    Originally, because the radius at the inside corners of the Ford OEM hitches were more rounded than usual, getting aftermarket hitch accessories that would fit was a problem. Ballmounts could be altered to fit by sanding off the powder coat at the corners. In the meanwhile, Reese has altered the design of the ball mount slightly by rounding the shank edges so that it will be compatible with the Ford OEM 2-1/2 inch receivers. I have confirmed this with Reese. The # RP45323 ballmount used...

    It sounds like the trailer hitch that came on your 2015 Ram 2500 Diesel has a 2-1/2 inch hitch receiver. If this is the case, I can certainly help you find a ball mount that will work well for you! There are a couple of options to get a ball mount that will work for you. One option is a reducer sleeve, such as the Curt Hitch Receiver Reducer Sleeve # C45405. This will allow you to use your 2 inch ball mount or other 2 inch hitch accessories inside your Ram's 2-1/2 inch receiver. All of...

  • Ball Mount with 2-1/2 Inch Shank to Fit the Factory 2-1/2 Inch Trailer Hitch on a 2009 Ford F-350
    The Reese Titan accessories used to have more squared edges and the Ford Super Duty 2-1/2 inch receiver requires something with more rounded edges like # AMSCV-2. It still may be a tight fit and in those cases, usually if you remove some of the powder coat from the ball mount shank (not any of the metal) you can get those snug accessories to fit properly. But we have had confirmation from a customer with a 2011 Ford Super Duty that it does fit his 2-1/2 inch receiver.

  • Recommendation for Removing Rattle from a Ball Mount on a 2011 Ford F350
    What you could get to help with the rattle is an anti-rattle device such as the Roadmaster Quiet Hitch # RM-061. This product basically will pin the ball mount to the hitch opening and will prevent all the rattle and noise you are trying to get rid of. Check out the review video I attached for this product also. The Reese Ball Mount # RP45323 you referenced is not designed to fit in 2 inch hitches and would not work for you at all so I would not recommend it for you.

  • Can a Ball Mount for a 2-1/2 Inch Class V Trailer Hitch be Used in the Rise Position
    Depending on the ball mount, you can use it in the rise or drop position. Some ball mounts, like # 45291, can only be used in the drop position. The Reese Titan Ball Mount, # RP45323, that comes in the etrailer Ball Mount Kit, # EBMK25518, can be used in the rise or drop position. It will provide 3-1/2 inches of rise or 5 inches of drop.

  • Will the Use of a 2-1/2 Inch to 2 inch Trailer Hitch Reducer Sleeve Reduce the Hitch Capacity
    You have a couple of options. The best thing to do would be to use a ball mount that fits in your hitch. The reason is that you will not have to worry about a reducer sleeve fitting, any capacity reduction, or adding another component in the system. For 2-1/2 inch receivers we have # RP45323 for an 18,000 pound fixed ball mount. The other option is to use a reducer, # C45405. The hitch capacity should not be dramatically changed so if it is rated to tow the 13,000 pounds you need to tow,...

Your trailer loaded will probably weigh about what your tow vehicle weighs, if not more. The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow, this figure also includes the weight of any cargo behind the rear axle of the tow vehicle.

  • Can a 2 Inch Ball be Included in a Ball Mount Kit Instead of a 2-5/16 Inch Ball
    What you can do is get the parts individually since we can't swap the balls out in a kit. The ball mount is # RP45323 and the bag is # ETBMB. For a 2 inch ball that will fit use # A-90. But keep in mind that the ball is rated for 10,000 pounds which is less than the ball mount which is rated for 18,000 pounds gross trailer weight and 2,000 pounds tongue weight.

Then, you'd use a ball mount like the # BH20 from CR Brophy. The # BH20 offers a 2 inch drop (we don't have anything in a 3 inch drop) and a hitch pin hole to ball mounting hole distance of 13-1/4 inches. For a 2 inch ball, you'd use part # A-90.
