This is the second hitch and lock we have purchased from etrailer , same item # both times. Excellent hitch, the quality and machining is outstanding. it is light to carry yet very beefy .

by:

About 2 months into using this product, I noticed that it had cracked all the way through on one side and the end came off. This could have been real bad if it would have wiggled out and the ball come loose when I was pulling a trailer. 745580

This keeps my "Mount - FA49-00-5925" where it belong, on my truck! 745134



- FA86-00-3685
by:

A direct hammer strike would shear off the lock. Best thing to say is it's an honest man's lock but I dont think it would be considered a theft deterrent as the locking head wobbles a bit after locking. 740020



- FA86-00-3685
by:

This product looked very nice on line , It had great reviews and the price was right. The hitch will be used on a work pick hauling multiple trailers which is why we need the versatility of the two ball sizes. We also bought the recommended lock set for this hitch. We were very impressed with the hitch once we received it , which came very quickly and in great shape. I would recommend this product at this time. 737246

- FA86-00-3685

It has a cheesy rubber cap that the carwash brush will knock off. Then it is just a matter of time for the lock to fill with dirt, etc making it very difficult to unlock. Almost never got it off after a couple of months. It would be fine if you didn't leave it on the truck. Of course, if you didn't why would you need a lock. 711409

Ask the Experts about this Fastway Trailer Hitch Lock

  • Trailer Hitch Lock and Adjustment Pin Lock Set for Flash E Series HD Ball Mounts
    The Trailer Hitch Receiver Lock # e98881 is the longest of the hitch receiver locks available and it has a 3-5/8" inside width, which you can use as the lock for your Flash E Series HD Adjustable 2-Ball Mount # FA42-00-2825. There is not a separate locking adjustment pin available, however, which is what you may have been referring to. For that you will need the Fastway Trailer Hitch Lock and Adjustment Pin Lock Set for Flash E Series HD Ball Mounts # FA86-00-3685. This lock set...

  • Will Fastway Trailer Hitch Lock be Safe for 18,000 lb Rated Hitch?
    The Fastway Trailer Hitch Lock and Adjustment Pin Lock Set # FA86-00-3685 does not have a particular weight capacity. It has been designed for use with Fastway Flash E Series ball mounts like # FA42-00-2825. The lock set will fit 2-1/2" receivers and has a 5/8" pin diameter. I have added a video review of this product for you to take a look at.

  • Recommended Locking Hitch Pins 5/8 Inch Diameter Keyed Alike for 2-1/2 Inch Trailer Hitch Receiver
    The Fastway Trailer Hitch Lock and Adjustment Pin Lock Set for Flash E Series HD Ball Mounts # FA86-00-3685 does not allow a 3rd pin keyed alike although the 2 in the kit come keyed alike. If you want 3 pins 5/8 inch diameter, then our etrailer.com Hitch Receiver Lock - Extra Long - Flush Design for 2-1/2" Trailer Hitches # e98881 is the only option, but you can get as many as you like. This will work with the Fastway Trailer Hitches but won't have separate lengths like the kit.

  • Weight Capacity of Fastway Trailer Hitch Lock and Adjustment Pin Lock Set # FA86-00-3685
    The Fastway Trailer Hitch Lock and Adjustment Pin Lock Set # FA86-00-3685 referenced in your question does not have a specific towing weight capacity. These will be used to secure the ball mount shank into the hitch receiver and the ball mount platform to the ball mount on the Flash E Series Ball Mounts like # FA42-00-2625. You will simply follow the weight capacity of the ball mount or whichever component in your towing system has the lowest rating.

I instead recommend looking at the Fastway Flash E Series HD Adjustable 2-Ball Mount # FA42-00-2825.

  • Comparing Fastway and Weigh Safe Adjustable 2 Ball Mounts for a 2018 Ram 2500 Tradesman
    If you plan on only hauling bigger trailers with your 2018 Ram 2500 then I recommend going with the Flash E Series HD Adjustable 2-Ball Mount # FA42-00-2925 for a few reasons. The first is that it has a higher weight rating than the Weigh Safe 180 Hitch 2-Ball Mount # LTB10-25, and the second being that you can add the lock set # FA86-00-3685 to lock the ball mount and the adjustable ball. The Weigh Safe comes with a lock for the adjustable ball but you would need to use part # WS06...

  • Can Fastway Self-Locking Adjustable 3-Ball Mount be Used with 3 Inch Receiver and Reducer Sleeve
    I spoke with my contact at Fastway regarding the Self-Locking Adjustable 3-Ball Mount 2.5 Inch # DTALBM6825-3S referenced in your question. He stated that this actually will not work with the 3 inch receiver on your Ford F-350, even when using the Ford provided reducer sleeve. This is because of the design on the self-locking system that is utilized with this particular ball mount. The integrated locking knobs on the shank will do a great job of securing itself to the reducer sleeve, but...

  • 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...

  • Recommended Ball Mount With 2.5 Inch Shank And 14,500 lb Capacity

The Fastway Flash E Series HD Adjustable 2-Ball Mount - 2-1/2" Hitch - 10" Drop, 10" Rise - 18K # FA42-00-2925 will give you an 8-7/8 inch distance from the center of the hitch pin hole to the center of the hitch ball.

    We have a number of adjustable ball mounts that will fit the 2-1/2" receiver tube opening on your 2017 Chevrolet Silverado 2500 which I have attached for you. However, the Rapid Hitch Adjustable Aluminum Ball Mount Kit part # AM3400 or part # AM3405 are designed to fit a 2" receiver tube opening therefore will not work for you.
