works fine, with the newer 2020 HD trucks all coming with 3" receivers the locking pin shaft could be about 1/2" long. Barley locks but it does work fine. 884644


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 # BW74FR only has a 3-5/8" usable pin width so it will work on a 2", 2-1/2" and 3" trailer hitch receiver. It may be a little tight depending on the thickness of your hitch receiver's collar. If you prefer something a bit longer, I recommend using the DrawTite Hitch Receiver Lock part # BD580412 which has a 4" usable pin width that will be plenty for the 3" hitch receiver on your 2019 Ford F-350.

  • Recommended Keyed Alike Trailer Hitch Receiver Lock for 2 Inch Trailer Hitch
    There is an option for high-quality hitch receiver locks that where multiple can be ordered keyed alike, but the B&W Trailer Hitch Receiver Lock # BW74FR cannot be keyed alike. Instead, I recommend the Master Lock Trailer Hitch Receiver Lock # 1480DAT. This is a stainless steel lock that that is so durable it comes with a lifetime warranty, and it is also very easy to use. It is "push-to-lock" that you can hear audibly click so you'll know it is locked. I have added a link to a video...

  • Does B and W Locking Hitch Pin # BWTS51235 Have a Weight Capacity
    Hitch pins like the B and W part # BW74FR 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...

  • 2-1/2-Inch Hitch Pin Lock Available Keyed Alike
    The particular B&W Hitch Lock # BW74FR 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.

  • Could B&W Hitch Lock # BW74FR 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 # BW74FR that you referenced would work well in a 20k hitch installed on your 2019 Ram 3500.

  • Is There a Locking Pin for B&W Tow & Stow Ball Mount?
    Yes, for the B&W Tow & Stow, I recommend the Trailer Hitch Receiver Lock for 2", 2-1/2", and 3" Hitches - 3-5/8" Span, part # BW74FR. I've added a link to a video review of the hitch lock for you to take a look at.

  • Locking Pin for a 3 Inch Trailer Hitch Receiver on 2017 Ford F-350
    The Trailer Receiver Lock # BW74FR has a usable span of exactly 3-5/8 inches so you'll be cutting it really close. A better option is the Draw-Tite lock # BD580412. The usable span is right at 4 inches.

  • What Hitch Lock is the Most Corrosion Resistant
    I really like the Trailer Hitch Receiver Lock part # BW74FR 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 around it when I first get it and...

  • Recommended Ball Mount for 2 Inch Hitch With Both 1-7/8 and 2 Trailer Hitch Balls
    Since you need a pair of trailer hitch balls and have different trailers, I highly recommend an adjustable ball mount, the B&W Tow & Stow 2-Ball Mount - 2" Hitch - 5" Drop, 5-1/2" Rise # BWTS10038B. This is considered the highest-quality ball mount in the industry, and our customers who have used it agree, with some 900 reviews (as of this writing) giving it a nearly 5-star rating. The Tow & Stow has the 1-7/8" and 2" hitch balls you need and fits the 2" trailer hitch receiver that...

  • Extra Long Hitch Pin Lock for OEM Hitch Receiver on 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 # BW74FR. This stainless steel, flush-style hitch lock has a usable span of 3-5/8 inches, which is sufficiently long for your application. 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 review 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...

  • Roadmaster Active Suspension Enhancement for 2004 GMC Denali with Quadrasteer
    I have an option for you, but the Roadmaster Active Suspension Custom Leaf Spring Enhancement Kit # RAS4611 is not compatible with the Quadrasteer system on your 2004 GMC Sierra Denali. Your best bet and the only confirmed suspension enhancement solution that won't interfere with your Quadrasteer components, is the Timbren Rear Suspension Enhancement System # TGMRCK25S. These hollow rubber springs sit above the rear axle to help stabilize and level your Sierra.

  • Vertical Measurement of B&W Tow & Stow 3-Ball Mount for 2-1/2 Inch Hitch
    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...

  • 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...

  • Trailer Hitch for Towing with a 2012 Chevy Tahoe
    The only trailer hitch that was designed for your 2012 Chevy Tahoe is the Curt Trailer Hitch Receiver # C13161. The Ultra Frame Trailer Hitch Receiver # 41947 is a pretty big hitch that is designed for a 2012 Chevy Silverado 3500 cab and chassis model which is pretty different to what you have. With that being said, it looks like your Tahoe has a towing capacity range of 5,200 lbs - 6,000 lbs so since the Curt is rated for a max of 6,000 lbs you will be able to tow with your Tahoe to...

  • Recommended Towing Package for 2017 Hyundai Santa Fe XL
    For your 2017 Hyundai Santa Fe XL Limited I recommend starting with the Curt Trailer Hitch Receiver 2" # C13153. This will give you a strong hitch and will allow your spare tire to be reinstalled without any issues. 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,...

  • 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...

  • Availability of Adjustable Ball Mount Where Platform Can be Stored Under Hitch
    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...

  • 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 # BW74FR (or a standard pin if that's what you already have).

  • Recommended Stainless Steel Hitch Lock for 2-1/2 Receiver
    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 # BW74FR. This heavy-duty locking pin features a stainless steel construction throughout and it uses a tube key cylinder (instead...

  • 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 # BW74FR 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.

  • 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 # BW74FR. I have attached a full list of options for you as well.

  • Solutions for Towing with a 2020 Chevy Silverado 2500
    No matter what kind of towing we got you covered. 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. What makes this ball mount so great is that it comes with...

    I confirmed with my contact at B&W that the Trailer Hitch Receiver Lock for 2", 2-1/2", and 3" Hitches - 3-5/8" Span, part # BW74FR is in fact made right here in the USA (Kansas to be exact). Another great American made option is the etrailer Trailer Hitch Receiver Lock # e98881 which also has a 5/8" diameter pin, an inside width of 3-5/8". Hitch receiver locks are not rated for any kind of weight capacity simply because they do not bear the weight of the trailer like one may think....

  • Will B&W Tow & Stow 2-Ball Mount BWTS20040B Fit a Class V 2-1/2-Inch Hitch
    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...

  • 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 # BW74FR 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...

  • Weight Capacity of B&W Adjustable 2-1/2-Inch Ball Mounts BWTS20040B & BWTS20040C
    With a multi-ball adjustable ball mount like the B&W # BWTS20040B and the similar chrome-finish model # BWTS20040C, both intended for 2-1/2-inch hitches, the weight rating depends on which of the hitch balls is in use. 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 # BW74FR.
