They will do what I need them to do, but they do not fit the hole very snuggly and the hitch will rattle because of that 908688

Why invest all of that money into a E-Series ball mount and not protect your investment with anything but lockable pins? If you're doing it, do it right and get the pins. I'm glad Adam E recommended these to me. 867575

I like the trim design and they look good with the hitch. The lock works smoothly. Hopeful it will remain this way after more exposure to the elements. However, I think if during machining of the lock end if there could be some kind of ridge near the lock would be good to help keep the rubber dust/water cover from coming off so easily. TH 861987

Worked perfectly fit my 2019 F 350 with a 3" receiver like it was made for it, also a trick I found out long ago spray the lock with dry graphite, this will solve any water / rust / sticking problems. 815665

The 1/2 “ pin is to short for the height adjustment on the trailer hitch it won’t lock guess I’ll have to find one somewhere else 730972

These Fastway Trailer Hitch pins/locks work as expected. Key functions well and finish is good after one year of service. The rubber protective caps are a bit poorer quality than the rest of the unit. 635649

Great product!!! 613517



- FA86-00-3660
by:

Great product---great service. One thing to improve is to make the rubber cap more durable--withing using the locks a few times, one of the small bands that keep the cap on ,was broken--so now I have no way to keep that cap on. 609599



- FA86-00-3660
by:

Excellent product, perfect fit for the ball adjustment pin. Only reason for the 4 stars is that the hitch pin is a bit long. Not a deal breaker (still going to use it). 602742



- FA86-00-3660
by:

The Fastway Trailer Hitch Lock and Adjustment Pin Lock Set, they are not of the size advertised. The specs say that they are 5/8 inch. Not true. They are smaller and allow the ball to flop around in the hitch to the point that I feel they could become a fatigued point and possibly snap when under a load and flexing. 599241


Comments
The locks are specifically designed to work with a Fastway ball mount. One pin is 5/8, and the other one is a 1/2 inch in diameter.

Ask the Experts about this Fastway Trailer Hitch Lock

  • Keyed Alike Hitch Locks for 3" and 2" Receivers
    The Curt Lock Set for Adjustable Channel-Style Mounts part # C23556 will do the trick. These pins are rated as high as any hitch and ball mount will be. The Longer one has a usable length of 4.25" while the shorter is 3.25" which will be great for your 3" and 2" receivers. While it is not the typical solution it is the only keyed alike option I currently have available. (May 2020)

    The Fastway Flash E Series Adjustable, Aluminum Ball Mount - 2 Chrome Balls - 6" Drop, 7" Rise - 10K, # FA42-00-2600 you said you have is a fit for 2 inch hitch receivers not 2-1/2 inch hitch receivers. The Fastway Trailer Hitch Lock and Adjustment Pin Lock Set for Flash E Series Ball Mounts, # FA86-00-3660, is a fit for this hitch and its compatible 2 inch receiver opening measured inside to inside. I'm guessing that you measured the receiver from outside vs. the inside opening and this...

  • Replacement Key Needed for a Flash E Series Adjustable 2-Ball Mount
    If you don't know the key number for the current lock on your Flash E Series Adjustable 2-Ball Mount # FA42-00-2600 and the previous owner doesn't know the number, you can still use the ball mount but you will need to get the current lock cut off. Once it is removed you can use the Hitch Lock and Adjustment Pin Lock Set # FA86-00-3660 to lock the ball platform AND the ball mount to deter theft.

  • Recommended Adjustable Ball Mount With 2-5/16" Hitch Ball for 7,000 lb Trailer
    So the answer to the exact adjustable ball mount you need really depends on the amount of rise or drop you require. If you aren't sure how to measure for that, I've added a link to a help article detailing how to determine that. With that in mind, I'll give you some options, and I also want to point out that adjustable ball mounts do come with both a 2" hitch ball and 2-5/16" hitch ball, though if you never need the 2" ball you can simply store it away.

    I reached out to my contact at Demco regarding security options for the Recon 5th Wheel Trailer Hitch # DM8550045-5W. He said while they don't offer anything for this purpose they are perfectly okay with somebody using a locking hitch pin in place of the coupler pin that's installed to secure the base to the gooseneck ball. The included pin features a 1/2 inch diameter and 4 inch length so you will need something that matches those dimensions. The closest option we have available comes...
