These worked great for my teardrop trailer "Lock & Roll" hitch. The smaller diameter pin locks the arms in place around the trailer side portion and the other locks the vehicle side into the receiver. The hitch originally came with just a pin and safety clip for the arms and even if the pin fell out the hitch would not disconnect due to it's design. Though this lock set is for an entirely different trailer hitch, it worked perfect for the Lock & Roll application. Was very happy to be able to find such a set-up. Thanks etrailer.

I bought a very nice ball and hitch from etrailer and wanted some protection against theft. This fits the bill nicely.


Comments
These do keep the hitch safe from theft but do nothing for hitch slop and wiggle so I ordered a Roadmaster Quiet hitch that took care of that problem nicely.

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

The only product I could find after two years to fit my adjustable height hitch. Thanks for a quality product!


Comments
Excellent!

So far so good after a year. I haven’t moved them much since my ball usually stays in place for boating season and goes in the garage for most of the winter.



- FA86-00-3660
by:

Excellent quality, no worries towing anything anywhere



- FA86-00-3660
by:

The hitch adjustment pin lock has froze up after less than a year of use. The rubber cap did little to protect the lock cylinder. I would not recommend this product due to these issues. I will likely have to take my grinder with a cutoff wheel to it in order to salvage my $250 hitch.


Comments
Thank you for your business and your review, Jason. There is likely some corrosion inside the lock that is preventing the mechanism from working properly. You can get some spray lubricant like WD-40 or PB Blaster, let it soak for 15 minutes. If this does not work, try another spray of lubricant, let it soak for another 15 minutes, and try again.

I gave it a three star because I believe that the pin should not be too much longer than the receiver it is going into, and this one is about an inch longer. I don't like how it has the ability to move around. Plus the lock didn't seem like it really "clicked" into place like a lock should. It is an ok product, I towed about 2 tons with it after I got it and it seemed to work fine. But given the opportunity to buy a different locking pin I would.


Comments
The adjustment pin lock set part # FA86-00-3660 is designed for Flash E series ball mounts and a 2 1/2 inch hitch receiver opening. It sounds like you may have a 2 inch hitch receiver opening. The span of the fastway locks part FA86-00-3660 is 3 5/8 inches for the hitch receiver lock and the other locking adjustment pin has a 3 7/8 inch span. If you are looking for a lock for a 2 inch hitch with a traditional style ball mount I recommend part # DT30005. Part # DT30005 fastway locks are designed for a 2 inch hitch includes a barrel style key and has a usable span of 2 1/2 inches.

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.



- 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.


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.

Excellent hitch pins and look great too.



- FA86-00-3660
by:

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.



- 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).



- FA86-00-3660
by:

Very functional, fine looking product. The only negative would be the key caps. They are easy to fall off.


Comments
Hitch works great, very handy and strong. The only problem I have had is the stinger size difference with my Tundra. There is a lots of looseness. I suspect it is the size difference between metric and US standard.
Steve - 12/01/2020


- FA86-00-3660
by:

Excellent product. The two different sizes really add to the versatility of the use. I used one of the pins for a bike hitch rack and it worked really well.



- FA86-00-3660
by:

Customer service was great. I ordered a pair of locking pins as well as an adjustable mount. Apparently, the locking pins were obsolete and I actually got a call from one of the customer service representatives asking if I wanted something different or just cancel that portion of the order. I received the order within the expected timeframe and the quality of both products was as expected. I couldn't have asked for a better experience.



- FA86-00-3660
by:

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



- FA86-00-3660
by:

Good overall in dry environment. Once u get into wet stuff dirt and rust clogging up keyholes even with covers. Had to cut them off with grinder after April trip to East Coast.



- FA86-00-3660
by:

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



- FA86-00-3660
by:

These locking hitch pins are just perfect. Delivery was quick and they are long enough for my hitch receiver. Thank you.



- FA86-00-3660
by:

This lock set is a very high quality set. It also looks great and will give me peace of mind. They are very easy to use with the one key fitting both locks. Very satisfied.



- FA86-00-3660
by:

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.



- FA86-00-3660
by:

Pin quality is excellent, however, they are extremely long. Not sure they were made so long. My thoughts are that the variation between different 2" receivers should not require them to be this long.



- 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.



- FA86-00-3660
by:

Excellent product. Works well and is f unctional.

  • 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)

    I called Lock N Roll and they said that if you want to use locking hitch pins, then they recommend the 2 pc set from Fastway # FA86-00-3660. The hitch receiver lock diameter is 5/8" and is 6-3/4" long. The locking coupler pin is 1/2" diameter and 7" long. This set is nice since they're keyed alike, making it easier for you to use them, while providing two points of security, making it harder for thieves. Just note that these locks are a deterrent for opportunistic theft. If you want...

    If you have a 2-1/2 inch adjustable ball mount like the part # DTSTBM6825-2S which has a standard pin hole for the hitch pin you would want a hitch lock like the part # e98881 which is longer and designed for the larger hitch size.

    Absolutely! B&W recommends the Locking Pin Kit from Infinite Rule, which we carry as part # 34061775-D. The locks are manufactured in the USA, are keyed alike and are specifically designed for the B&W Tow and Stow so they fit perfectly. The # FA86-00-3660 locking pins you'd looked at wouldn't have an inside span long enough to fit the Tow and Stow ball mount.
