Video Transcript for Fastway Ball Mounts - Fixed Ball Mount - DTLBM8400 Review

Today, we'll be reviewing part number DTLBM8400. This is the Fastway FLASH self locking aluminum ball mount. The solid one piece ball mount with the built in drop or rise lets you match the ball height of your vehicle with the tongue height of your trailer. It's got the convenient self-locking system that's going to lock the ball mount to the receiver tube. The built in locks are a great feature to have because they can't get lost like other kinds of hitch locks. It's going to feature lock seals that are double sealed to help keep out water and dirt.

It's also going to stand up well against rust and corrosion. They're not going to require any maintenance. It's going to come with two keys. The keys use a pick resistant tooth style design. The ball mount itself is machined from a solid piece of aluminum so it avoids welds which can cause weak points that may break over time but that one piece of aluminum produces a lightweight, solid, strong ball mount. It's also going to feature a nice polished finish which is going to create a high-quality appearance.

The keys just go into this portion here and as you rotate the key it's going to bring in the pins allowing this to slide in to a 2-inch x 2-inch trailer hitch receiver. Once you get it in line with the pin holes, you rotate the key, push out the pins and removing the key is actually going to lock the mount inside the hitch. The ball hole diameter is going to give us a measurement of 1 inch so that's important to know when choosing a hitch ball. You want to make sure that the shank of the hitch ball does not exceed the ball hole diameter and if we measure the draw bar thickness which is this portion here, it's going to give us a thickness of right around 1 inch. It's going to offer a towing capacity of 14,000 pounds with a maximum tongue weight capacity of 2,000 pounds. We're going to go ahead and bring our pins in, that way we can install this inside our hitch. Take it and slide it in to the receiver tube, get our pin holes to line up, simply rotate it, push out the pins and then lock it in place.

It's also got the nice dust cap to protect the lock. With the ball mount in this position, if we take a measurement from the center of the hitch pin hole to the center of the ball hole, that measurement is going to measure about 8 1/2 inches. With it in the dropped position, it's going to give us a drop of 4 inches measuring from the ball platform to the inside top edge of the receiver tube. If you flip this over to the rise position and do that same measurement, it's going to give you a rise of 3 inches. That's going to do it for today's review of part number DTLBM8400. This is the Fastway FLASH self locking aluminum ball mount.

I was really looking forward to the simplicity of an all in one mount and locking pin system. I'm not sure if I got a Friday afternoon product or what, but I ended up returning the ball mount due to poor quality machining. The rounding of the corners of the shank was off by up to a 1/16" leaving some sharp edges and less than ideal contact surfaces with the receiver. I'm not a machining expert, but sure looks like it was misaligned when placed in the machine to do the rounding. Then it looks like someone still tried to polish the resulting work as a couple of the bad edges had been slightly smoothed. Then somehow this got past quality control and out the door. Does not instill confidence in their manufacturing process, quality control and monitoring, or belief in what constitutes a deliverable quality product. I expect better for $100+. Etrailer was great about accepting a return and refunding me. Kudos to them. 688118

I'm a very picky buyer; like to research everything - and I also don't have a problem with paying a little more for quality - and for this aluminum ball mount that meant the polish/look of the mount, and even more important the quality of the locking mechanism. This product doesn't disappoint. I have no doubts this mount will take as much punishment as steel mounts and look 10 times better over time. I also appreciate having the integrated locking mechanism - cleaner look, in fact someone came up to me and told me they thought I'd forgot to but the bolt in it. So it looks great, does the job = all expectations met! 543582

Very nice quality, the photos of the product do not do it justice. It will look superb on my Jeep Grand Cherokee. I really can't wait for summer to put it to use and no more struggling with the old trailer hitch lock. 327423

It's a nice piece of equipment and I'm looking forward to using it a lot. Note that the anti-rattle feature is no longer installed in these hitch mounts. The anti-rattle features were almost never in the right position to do any good with the short hitch tubes of today. The manufacturer told me they were discontinuing them because of that. 138401


Comments
The hitch bar has been scarred a bit by a sharp edge on the mount tube but is otherwise working well up to now.

Very nice finish, and well designed product. The round key opens and locks the hitch in place, and the spring loaded balls in the receiver keep it from rattling on bumps. I'm using mine tounge up, and it's just the right offset to keep my trailex sports car trailer level when towing and low in the rear for loading and unloading cars. Non corrosive, nice design. 129025

Review from a similar Self-Locking in Trailer Hitch Ball Mount


Like most of the reviews on this product, a little skeptical on the locking pin in the receiver. Seems like it should extend out a little further when it’s locked in the receiver.... It is well built and looks great. It’s what I wanted and can’t wait to put it to the test! 573983

Have not used product yet, however customer service was excellent. I had received the wrong ball mount and contacted customer service. Dana was understanding and immediately sent out a return label and the correct ball mount. Couldn't ask for any better. Should be picking up new trailer in a few weeks and can't wait to use all the products I have purchased from etrailer.com 223292

Review from a similar Self-Locking in Trailer Hitch Ball Mount


I was very confused in trying to determine the type of hitch to use for my just purchased 2019 Ford Superduty truck. The good folks at E-trailer worked with me and I selected a hitch with just the right drop. Years ago I purchased several tires from these folks and they are wonderful to work with. Very professional and (most important) PATIENT!! 706320

Review from a similar Self-Locking in Trailer Hitch Ball Mount


I love this product. I have 2 different tow vehicles, and having the option to change the height of the ball is a big advantage. I also like the feature of having 2 different size balls on the same mount. This product has much flexibility and suites my needs perfectly. Plus it looks sharp. 369888

Review from a similar Self-Locking in Trailer Hitch Ball Mount


After about 7 months, the lock that locks and releases the pin to the receiver was completely frozen stuck, and the key to the lock twisted off (pretty flimsy). After re-lubing the pin and lock again, twisted the other key off. i had to mangle the lock to get it off of my truck, and unit is now completely worthless... 404043

Review from a similar Self-Locking in Trailer Hitch Ball Mount


Serves the purpose needed. Love the fact that it has a 2,000 lb tongue weight and a 14,000 lb tow weight. it gives me that extra safety margin. One big drawback is that I ordered two keyed alike replacement locks because I have another hitch different size but I am not able to remove the set screw following the instructions no matter how hard or what ever I use. So I am presently stuck with using two different keys and with a set of keyed alike locks. 591470


Comments
When its installed, Fastway uses a small amount of thread locker on the set screw, so its designed not to be easy to remove. Try spraying a spray lubricant like PB Blaster or WD-40 in the set screw hole. You might need to repeat this several times for the lubricant to penetrate. If several attempts of this doesnt work, you can use a # 1 extractor to remove the set screw. If that doesnt do the trick, I was told you could send the ball mount to Fastway, and theyd re-key them for a fee.

Still not able to remove the set screw to have two locking ball mounts with one key. i am able to remove the screws in my other two mounts but not this one. This one was put in two tight andor too much loctite.

You may try using some penetrating oil on the set screw to loosen it up a bit. Over time they can become harder to remove. We have a video to show how to swap out the lock cores.

Great solid hitch but the lock is poor quality. I left it on the truck for several months (with lock protection cap on) and one day I went to remove. Found lock tumbler had shifted and was unable to insert key to remove. Had to drill out lock to get ball mount off the truck. I know have a $80 aluminum paper weight. 591181

Perfect for the Subaru Crosstrek. You do not have to crawl under the vehicle to put the safety pin in place. This ball mount is also very light weight and does not rust. 409316
