The hitch receiver lock is made of a stainless steel construction, which provides the pure corrosion resistance. Now that we're done with the features, let's go ahead show you how to use it.

Go ahead and slide your lock through and insert your tumbler assembly on, pushing on and turn it a quarter turn counter-clockwise and secure, and fold the dust cover on down. There you have it. It's installed. With the hitch lock installed, you can rest assured that your ball mount will be protected and secured while you're going down the road.

This fits on a 2018 Toyota Tacoma 2" hitch! I tried another brand from a different manufacturer, and it was about 3/8 inch too narrow (span). This one works, albeit has a gap of about 1/2 inch or so. Not a problem, as others have commented that they use rubber washers between the shaft to fill up gap. The rubber boot appears to be a great way to keep the keyhole from getting dirt or debris inside. Really like the key as it's much better than a standard key lock. Cheers! 561558

Its working well. Had to put a 12 rubber shim to keep it from sliding around, but it looks great and no problems

After doing tons of research I decided to purchase a B&W hitch for my 2015 GMC 2500HD. Needless to say it was one of the best purchases I've ever made. Extremely well built unit. Much heavier than I anticipated it to be. Should last me many years. Thank you for a great AMERICAN built product. 316738

I have had my B&W hitch for over a year and I get lots of complements on the looks and features with being able to fold it under. It still looks new and I use it a lot. I am very satisfied and would buy it again. 621610

Bought the B and W Tow and Stow, lock and two extra pins. While you pay more; I can say you certainly get a good quality product. I am using this with a Dodge 3500 so I expect to tow heavier trailers and the three ball option should allow me to be very flexible. This is not my first purchase from etrailer. Every time I have used them it has been a positive experience. Good company and good, helpful people working there. Yes you can buy cheaper hitches but do you really want to chance it with your expensive toys and equipment? 440704

Great product. I use it on my 2016 Ram 2500. It is a perfect fit and has no vibration. B&W quality is always outstanding. I wouldn't buy any other brand. 7 inch drop and rise is more than enough on my stock height Ram 2500. My favorite feature is how you can stow it away when not towing. I'll post pictures of both with it out and stowed away. 329863

only had it for a day so far. first thoughts is it operates smoothly and cap stays on firmly. I like how it is all stainless steel and not just a silver coating that typically chip off and allow rust. 442831

still works great! i keep a little lube on it. the dust cap lanyard hasnt broken. still works like a champ. i do not live in the rust belt, so i have no experience with the effects of rust on it. thanks.

Ask the Experts about this B and W Trailer Hitch Lock

  • Best Hitch Pin Lock for a 2019 Ford F-350 with 3 Inch Trailer Hitch
    The Trailer Hitch Receiver Lock part # BWTS51235 only has a 3-5/8" usable pin width so I would not use it on a 3" trailer hitch receiver. It may work but that would be cutting it very close. Instead, I recommend using the Bulldog Hitch Receiver Lock part # BD580412 which has a 4" usable pin width that will be plenty for your 2019 Ford F-350.

  • 2-1/2-Inch Hitch Pin Lock Available Keyed Alike
    The particular B&W 2-1/2-Inch Hitch Lock # BWTS51235 you mentioned is not offered with the keyed alike option but we do have similar hitch pin locks that are and you can see them on the linked page. The one I recommend is the etrailer.com # e98881 which has the same 3-5/8-inch span as the B&W. Just select the keyed-alike option on the lock's page before adding the three pieces to your cart.

  • What Hitch Lock is the Most Corrosion Resistant
    I really like the Trailer Hitch Receiver Lock - Flush Design - 2-1/2" Hitches part # BWTS51235 that you looked at. B&W always uses the best quality materials available and tries really hard to protect everything from the elements. When working with customers I have never heard of this one failing. As always with any lock when left out in the elements indefinitely you may run into some. I have always had great luck with spraying a little light viscosity lubricant into the lock core and...

  • Locking Pin for a 3 Inch Trailer Hitch Receiver on 2017 Ford F-350
    The Trailer Receiver Lock # BWTS51235 has a usable span of exactly 3-5/8 inches so you'll be cutting it really close. A better option is the Bulldog # BD580412. The usable span is right at 4 inches.

  • Is There a Locking Pin for B&W Tow & Stow Ball Mount?
    There are hitch pin locks that will work with a B&W Tow & Stow such as # BWTS20040B. The lock you'll want is simply going to depend on the size receiver hitch that you have. Lock # BWTS51234 is for 2" hitches with a 5/8" diameter pin hole that is no wider than 2-3/4". Lock # BWTS51235 is for 2-1/2" hitches with a 5/8" diameter pin hole that is no wider than 3-5/8". I've added links to video reviews of the hitch lock for you to take a look at.

  • USA-Made Locking Hitch Pin for a 2-1/2 Inch Trailer Hitch

  • Could B&W Hitch Lock # BWTS51235 Work in 20k Trailer Hitch of 2019 Ram 3500
    Since hitch pins don't ever carry the weight of a trailer they aren't rated for trailer weight like you'll see other towing components. The Trailer Hitch Receiver Lock # BWTS51235 that you referenced would work well in a 20k hitch installed on your 2019 Ram 3500.

  • Does B and W Locking Hitch Pin # BWTS51235 Have a Weight Capacity
    Hitch pins like the B and W part # BWTS51235 don't have weight capacities listed typically but this was designed for Class V hitches like yours and easily would be able to tow a 10,000 lb trailer. The reason they don't have capacities is that they don't usually bare the weight of the trailer like you might think. The tongue weight of the trailer puts so much vertical pressure in the hitch tube that the ball mount is held in place by that. This is why the companies don't like to give capacities...

  • Extra Long Hitch Pin Lock for 2008 Toyota Tundra
    The OEM hitches on some trucks including your 2008 Toyota Tundra can have an extra-wide collar on the receiver tube that can interfere with some standard locking hitch pins. An extra-long model such as our # e98881 will work great.

  • Recommended Stainless Steel Hitch Lock with 2-7/8 Inch Span for 2010 Toyota Tundra
    For the trailer hitch receiver on your 2010 Toyota Tundra, I recommend looking at the B&W Trailer Hitch Receiver Lock # BWTS51235. This stainless steel, flush-style hitch lock has a usable span of 3-5/16 inches . The weather-resistant plastic dust cap will also keep the cylinders free from water and debris. 2 keyed-alike tube keys are included. I have attached a short video demonstration on this hitch lock that you can also check out.

  • Coupler Height of Yakima EasyRider Double Decker Trailer
    From the ground to the bottom of the coupler for the Yakima EasyRider Double Decker Trailer # Y08129 it measures 16". To ensure that you tow the trailer level you just need to measure from the ground to the top of the inside of the receiver on your 2020 Jeep Gladiator and then choose a ball mount that has the correct rise/drop that matches up to the EasyRider. I have attached a link to a helpful article about choosing a ball mount that you can reference. I tried to find what the height...

  • Does the B&W Tow & Stow 3-Ball Mount Have an Anti-Theft System?
    The B&W Tow & Stow 3-Ball Mount # BWTS20049B has a slot cut into the adjustment channel, which you can see in the accompanying photo, that stops the platform from being removed when the ball mount is installed in your hitch receiver. Further, you can get a hitch lock such as # BWTS51235 to secure the mount in your 2-1/2" hitch for total safety. I've added links to video reviews of both parts for you to take a look at.

    I took a measurement of the B&W Tow & Stow 3-Ball Mount # BWTS20049C and found from the base to the bottom of the receiver it measured about 8-1/4 inches while the overall vertical measurement was about 11 inches. I have made a photo for you displaying these measurements. This 3-Ball Mount, which is Chrome but also available in Black at part # BWTS20049B, fits 2-1/2 inch trailer hitches and has a 1-7/8 inch hitch ball (3,500 lb capacity), 2 inch hitch ball (7,500 lb capacity) or 2-5/16...

  • Recommended Trailer Hitch Receiver for a 2019 Nissan Titan SV
    Out of the Draw-Tite # 76154 and the Curt # C13304 trailer hitches I recommend the Curt option for your 2019 Nissan Titan SV because it has a wider footprint which makes installing the spare tire easier, plus Curt is known for having stronger welds and a thicker powder coat for their trailer hitches over the Draw-Tite trailer options. This means that you'll be getting a higher quality product that is backed by a limited lifetime warranty. I have attached an installation video and some pictures...

  • 10K Trailer Hitch and 7-Way Wiring Needed for a 2017 Ford F-150
    The only trailer hitch that is rated for 10K right out of the box for your 2017 Ford F-150 is the Curt # C14017. All of the other options require a weight distribution system to achieve this weight rating. With that being said, it is important to note that you shouldn't exceed the listed trailer weight rating for your F-150 either. According to the Ford Towing Guide only about half of the 2017 F-150 configurations have the ability to safely tow up to at least a 10K trailer so you'll want...

    I do have a solution for you but unfortunately the Flash Solid Steel HD Adjustable 2-Ball Mount # FA49-00-5925 doesn't have the ability to store the platform on the underside and this isn't available with just one hitch ball. For a similar option we have the B&W Tow & Stow 3-Ball Mount # BW54FR. This does allow you to store the hitch balls on the underside, it fits a 2-1/2" hitch receiver without an adapter, and you're able to lock the whole assembly to your trailer hitch with just one...

For your wiring, I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56184 to get your 4-way and then add the Universal Brake Controller Wiring Kit # ETBC7 Kit to get your 7-way. This kit comes with the wiring, the connectors,...

    The B&W Tow & Stow 2-Ball Mount # BWTS20040B is a Class IV adjustable ball mount that will work in a 2-1/2-inch hitch with either a Class IV or a Class V rating. The weight ratings differ for the two included hitch balls; the 2-inch is rated for 7500-lbs but the 2-5/16-inch ball is rated for 14.5K trailer weight. You can use this Class IV ball mount in a 2-1/2-inch Class V hitch so long as you remain within the capacity for the particular ball. You can lock it to the hitch with part...

    The Master Lock Trailer Hitch Lock # 1469DAT referenced in your question features a stainless steel swivel head (the actual lock core/cylinder at the end) but the pin itself is constructed of chrome-plated steel like you mentioned. For a true stainless steel locking pin that will work great for the 2-1/2" hitch receiver on your Tundra I instead recommend the B&W # BWTS51235. This heavy-duty locking pin features a stainless steel construction throughout and it uses a tube key cylinder...

  • Can the BOLT Trailer Hitch Receiver Locks Be Re-Coded To Multiple Keys
    The BOLT Trailer Hitch Receiver Locks like part # BL7023585 can only be coded to one ignition key. Therefore, you can't transfer it from vehicle to vehicle. This would allow anyone with the same truck to steal hitch pin lock and whatever you had attached to the trailer hitch if that were the case. Instead, you will want to use a standard hitch pin lock like the Trailer Hitch Receiver Lock part # BWTS51235. I have attached a full list of options for you as well.

  • 2-1/2" to 2" Hitch Reducer Sleeve to Fit 2-1/2" Depth of GM-Style Hitch Pin Hole
    We actually do have one that matches what you're looking for! The B&W Hitch Receiver Reducer Sleeve # BWRHXA2182 has 2 different sets of pin holes depending on what kind of hitch receiver you have. The pin holes that are more towards the middle have that 2-1/2" measurement you're looking for and you'll use a 5/8" pin like the locking B&w Hitch Pin # BWTS51235 (or a standard pin if that's what you already have).

    The weight rating for the B&W Tow & Stow 2-Ball Mount # BWTS20048B (and for the chrome version # BWTS20048C) depends on which of the two included hitch balls is being used. The smaller 2-inch ball is rated for 7500-lbs towing capacity but the 2-5/16-inch ball can handle trailer weight up to 14,500-lbs. These ball mounts can be secured to your 2-1/2-inch hitch using their matching pin lock # BWTS51235.

  • Tongue Weight Ratings of the B&W Tow & Stow 2-Ball Mount # BWTS20040C
    The tongue weight ratings of the B&W Tow & Stow 2-Ball Mount # BWTS20040C are 10% of the towing weights. So for the 2" ball with the 7,500 lb towing weight it is 750 lbs and with the 2-5/16" ball with the 14,500 lb towing weight it is 1,450 lbs. I do recommend using the Trailer Hitch Receiver Lock # BWTS51235 with this to discourage someone from running off with it. The ball mount part is actually in a channel so when the shank is locked in your hitch receiver the ball mount part can't...

Out of all of our towing products my recommendations all include part from B&W because they make some of the best towing equipment on the market (made in the USA!) which is backed by a lifetime warranty. If you will be bumper pull towing then I recommend the B&W Tow & Stow 3-Ball Mount which comes to fit both a 2" hitch as part # BWTS10049B or a 2-1/2" hitch as part # BWTS20049B.

As you might expect, the larger ball will have a higher weight rating. The 2-inch hitch ball is rated for 7500-lbs towing and the 2-5/16-inch ball is rated for 14,500-lbs. Either ball mount can be used along with a locking pin # BWTS51235.

    Yes, I confirmed that the Curt 2" Trailer Hitch Receiver # C14108 is a fit for your 2007 GMC Sierra 2500HD Classic with the 6-1/2' bed. If you need a wiring connector then I recommend the Hopkins # HM40975 which will be an exact replacement to fit in the bumper cutout (if that's what you have). If you don't have the bumper cutout then this can be attached to the trailer hitch using the mounting bracket # 18136. To complete your towing setup you also need a ball mount.
