It's definitely nice to have the two locking pins keyed the same and not having to worry about someone stealing the ball mount or the entire hitch. Highly recommend.

I was surprised that the pin and lock both have a smooth exterior vs one having the engraved pattern so both ends wouldn't be slippery in damp/wet weather.
Overall both pins are long enough to fit through my 2.5" hitch/truck and my class E hitch/ball ends.

The hitch lock works as advertised. Only down side was it sticks out a fair amount on both sides making breakaway chain attachment a little difficult.

My Reese adjustable receiver hitch requires a lock with a 3 3/4” minimum shaft on the lock. This 4” fits fine. 3” fits receiver so now I have one key for both another plus for removing from vehicle to vehicle. Most all stores only carry up to 3 5/8” not long enough for the lock to latch. Actual lock piece is much heavier also.

Excellent product !
It solved the problem of having multiple different hitches in my truck.
Great looking, with a weight rating far greater than any other hitch I had.
I'm giving my other hitches away now !

I ordered the Flash Simple HD hitch and also bought the locking pins (Item #FA86-00-3685). With the 2" ball in position the locking pin was snug but worked. However when turned upside down to use the 2 5/16 ball the pin would not go completely through. etrailer quickly sent me a replacement which works fine. To be safe, I would suggest verifying the pin works in all position combinations.

Excellent customer service from sale to follow-up on order receipt. Product exceeded what was expected and arrived as promised. Needed a much heavier hitch for my 3/4 ton Duramax with a 2 1/2" receiver tube. Perfect combination of weight ratings and adjustability. Will definitely do more business with etrailer.

Pins are exactly what I needed for my extra wide hitch and great material. Easy to use and love the same key so not so many on key chain.

Just purchased a Fastway FLASH E-series HD adjustable ball mount for my new '17 F250 Superduty. The mount looks great out of the box and fantastic on the truck. Will be towing a triple axle trailer with 30' center console soon as well as a utility trailer off and on. Nice to have one set-up that's able to tow two different loads. The polished finish is very nice and the matching lock set looks very secure. Amazingly fast shipping from etrailer.com too. Even curious George likes it.

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.

I am using this product to make sure my Curt Adjustable 2-Ball Mount 2-1/2" Hitch (item # C45902) doesn't grow legs and walk away while I am not looking. They are a little pricey, but so was the hitch. They seem to be very well made. You can also add 5/8" washers to fill any gaps that you don't want.
I would recommend this product if you want to keep your hitch. Fits my 2011 Chevy Silverado 2500HD factory heavy-duty hitch perfectly.

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.

Product look good for about a month then it started to rust up. Then the lock wouldn’t open to adjust the hitch. Had to cut it off. Don’t waste your money. Poor quality . Hitch is also terrible lost its luster after a couple of months,both balls rusted up and loosened up. The money it cost isn’t worth it.

- Will The BulletProof Hitches BPH89MR Ball Mount Work For Towing A Trailer With A 2023 Sequoia?Welcome back, Jim! The BulletProof Hitches 2-Ball Mount for 2" Hitch - 6" Drop, 6" Rise - 10,000 lbs # BPH89MR looks to be a very good option for your 2023 Toyota Sequoia Platinum. This has 6" of drop, so with your hitch measuring 23-1/2" from the inside top to the ground (which is how it should technically be measured), it will put the ball at 17". The vast majority of trailers will have an 18" coupler height, so I think it's perfect. One thing to note though, Toyota tends to have thicker...

view full answer... - Does Flash Solid Steel HD Adjustable Ball Mount Come With 8 Inch Rise/DropI'm not sure if you're looking for rise or drop but the # FA49-00-5925 is the closest to 8" for the Flash Solid Steel HD. The only other option would be on the low side which is # FA49-00-5625. This has a 6" drop and 7" rise. If you stick with the Flash Solid Steel HD then you can use the # FA86-00-4225 for a locking hitch pin and adjustment pin. For an 8" rise/drop that fits a 2-1/2" receiver you could use the # FA42-00-2825. This has an aluminum shank with a capacity of 18,000 lbs for...
view full answer... - Adjustable 20,000 lb Ball Mount Option with Silver Colored Hitch BallI 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 both...

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.

view full answer... - Is There A Way To Lock The Fastway Flash Force Ball Mounts So They Can't Be Stolen Off My Truck?That’s a really good question, Kevin. The Fastway Flash Force ball mounts use standard pins and clips for the adjustable section, and there is an open notch in the vertical channel that allows the ball platform to slide off when the pins are removed. For normal towing, the included pin-and-clip setup is what holds the adjustable section in position. For theft deterrence, you’d want the Fastway Trailer Hitch Lock and Adjustment Pin Lock Set # FA86-00-3685. That lock set works with all...

view full answer... - How to Choose Adjustable Ball Mount for Chevy Silverado & 2-1/2 HitchWhen determining the rise or drop needed for a ball mount, there are two measurements you will want to take. Starting with your 2017 Chevy Silverado, you will want to take a measurement from the ground to the top of the trailer hitch receiver when the truck is on level ground. Then on your trailer, you will measure from the ground to the bottom of the coupler. If the hitch height on your truck is higher, you will need a ball mount with a rise, if the coupler measurement is higher, you...

So if you have a 2-1/2 inch receiver, you can use any of the following, depending on the rise or drop you need: - 6" Rise/Drop: Flash E Series HD Adjustable 2-Ball Mount # FA42-00-2625 - 8" Rise/Drop: Flash E Series HD Adjustable 2-Ball Mount # FA42-00-2825 - 10" Rise/Drop: Flash E Series HD Adjustable 2-Ball Mount...
view full answer... - How To Prevent Theft And Rattling Of Fastway Flash Force Adjustable Drop Hitches For Truck ReceiverHey Chris, great questions, and I do have a solution for you! For security on the Fastway Flash Force adjustable ball mounts, use the Fastway Trailer Hitch Lock and Adjustment Pin Lock Set # FA86-00-3685. That gives you one lock for the receiver connection and a second lock for the adjustable section. That second lock is important because the ball platform can be removed through the open notch in the adjustment channel if it is not locked down. For rattle, match the anti-rattle part to...

We have locking pin set # FA86-00-3685 that could potentially work for you. In this set the 5/8 inch diameter hitch lock has a inside pin length of 3-5/8 inches. The adjustment pin is also 5/8 inch and has a length of 4-1/2 inches. We also have lock set # AM3492. It also includes two 5/8 inch diameter locking pins.

view full answer... - Can Fastway Self-Locking Adjustable 3-Ball Mount be Used with 3 Inch Receiver and Reducer SleeveI 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...
view full answer... - Can I Use A Standard Pin And Clip With The Fastway Ball Mount FA42-00-2825Yes you can absolutely use a standard pin and clip with the Fastway # FA42-00-2825. Any 5/8" diameter pin with at least 3-5/8" of usable space will do fine. I recommend the Gen-Y hitch pin # 325-GH-099. This will be very similar to the pin and clip that comes with the Fastway # FA42-00-2825. If you have no need for a lock it will do just fine.

All you have to do is order the following and you're set: - Replacement Tube Keys for Fastway Universal Coupler Lock - Key 311 # FA-KEY-311 This will get you two keys which is nice as you can keep one for a spare.
view full answer... - Weight Capacity of Fastway Trailer Hitch Lock and Adjustment Pin Lock Set # FA86-00-3685The 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.
view full answer... - How to Order Replacement Key for Fastway Trailer Lock FA86-00-3685I checked your order notes and it looks like you have the part # FA86-00-3685. With the key number you have on your keys you can order replacements. What you will need to do is search our website for the FA-KEY- followed by the key number and you'll see the correct key. For example if you have key number 302 the key you would need is part # FA-KEY-302.

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.

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. The difference between them is that part # AM3405 has a nylon cap which will not require lubrication. They both have zinc plated hitch balls. Instead, I recommend...

There may very well be one with a 1/2 inch pin, but not that we carry; if you let me know what specific ball mount you have I may be able to confirm. What we offer...

Other options are available but they would be like the Flash E Series HD Adjustable 2-Ball Mount for 2-1/2 inch Hitch, Item # FA42-00-2625.
