Designed for your Flash E Series ball mount, this lock set includes a 1/2" lock to replace the adjustment pin that holds the ball mount platform in place on the shank, and a 5/8" lock to secure the ball mount in your 2" receiver.

by:

Works just fine. Fits as it should for my application and the lock mechanism works well. The only issue I've had with them is the rubber caps fell off all the time and I eventually lost one. I'll probably need to lube it more often as a result of the missing dust covers. It also may be more prone to freezing up in the winter. Funny how a missing $.03 part can be a problem.



by:

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.



by:

These lock pins look great are easy to use and work very well. I have just installed them on my truck so will see how well they hold up to the weather.

works great, still look good after a NY winter

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

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.



by:

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



by:

Nice quality and easy to use!



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.

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.



by:

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.

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.



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.

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.



by:

Worked perfect to lock my hitch ball and the smaller one locks my 5th wheel hitch and just one key!



by:

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

Thomas

Excellent!



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.



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.



by:

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.



by:

Hitch and Adjustment Pin lock set were received quickly after being out of stock last month. So glad I was able to secure these to compliment my Fastway adjustable hitch. Nice quality locks which perfectly match my Fastway hitch.



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.



by:

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



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.



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.



by:

This is a perfect set to go with my trailer hitch. FYI the hitch pin lock fits my 3"inch receiver perfectly



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).



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.



by:

Needed locks/security for a new Flash E adjustable ball mount. Found this matching combo to be a perfect fit along with quality materials and construction. Also, excellent service from etrailer.com; quick delivery.



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



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.

  • Recommended Keyed Alike Locking Pins for B&W Tow and Stow Adjustable Ball Mount
    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.

  • Can Fastway Flash 2-Ball Mount with Built-In Scale Be Used for Towing
    Yes, you can use the Fastway Flash 2-Ball Mount with Built-In Scale # FA54FR! Fastway has rated this for towing up to a 10K trailer with 1K tongue weight so as long as you aren't exceeding those capacities this is more than just a fancy tongue weight scale. I also recommend securing your investment with the Lock Kit # FA86-00-3660. This locks the shank to your trailer hitch and then the ball platform to the shank so everything is secured!
