  • Corrosion Resistant Coupler and Receiver Locks to Secure Trailer
    We don't have exactly what you're looking for, but I may have a solution for you. The etrailer Trailer Hitch Receiver & Coupler Lockset # e99039 has both a hitch receiver lock and a coupler lock that are keyed alike. However, they are not stainless steel. They're steel with double-chrome plating to resist rust and corrosion. If stainless steel is more important to you than having them keyed alike, the B&W Trailer Hitch Receiver Lock # BWTS51234 will lock your ball mount to your...

  • Keyed Alike 2 Receiver Hitch Locks and a Trailer Couple Lock
    As long as the locks are from the same manufacturer and listed as being able to be keyed alike, we can accommodate your request. With the locks you are interested in, I would like to suggest one lock set hitch and coupler lock set, part # e99039, that includes a hitch lock and coupler lock, and then purchasing one extra hitch lock, part # e98880.

  • Recommendation for Keyed Alike 2 Inch Hitch Lock, 1-1/4 Inch Hich Lock, and Coupler Lock

This will give you one 2 inch hitch lock, along with a 4-1/8 inch coupler lock for trigger style couplers. Then, for the 1-1/4 inch hitch locks, I recommend the etrailer Trailer Hitch Receiver Lock # e98879.

  • Trailer Hitch Size on a 2002 Chevy Silverado
    If you have the factory hitch installed on your vehicle, then it is the 2 inch by 2 inch receiver hitch. If it is an aftermarket hitch on your vehicle then it is most likely a 2 inch receiver hitch. You will need to measure the inside width of the opening on the hitch where the receiver slides in. The measurement should be apparent when you use a ruler or tape measure. Below, links are posted to our 1-1/4 and 2 inch hitch pins and instructions for measuring your hitch.

  • etrailer Trailer Hitch Receiver Lock on a 2011 Toyota Tacoma
    Unfortunately, we don't have an exact listing as to which model years the etrailer Trailer Lock # e99039 doesn't fit but if your trailer hitch receiver opening has an outside measurement more than 2-5/8 inches it will not. If it's less then it'll work great for you.

  • Hitch Lock Recommendation for 21-Foot Trailer Towed With Hayman Reese Hitch
    We offer a range of different trailer locks, from straight hitch pin types like the etrailer Lockset # e99039 that you referenced to coupler locks like the Fastway Universal Trailer Coupler Lock # DT25013KA that fits 1-7/8-inch, 2-inch and 2-5/16-inch trailer couplers. Trailer weight does not matter when it comes to selecting a lock. What matters is that you choose one that is long enough for the width of your receiver opening.

  • Available Hitch Pin Locks in Different Sizes
    There are a variety of hitch pin locks for you. Should you need a receiver and coupler lock set, I recommend the etrailer # e99039. This is a keyed-alike set which fits 2" hitches and 1/2" wide latches. If you are seeking a standard hitch pin and lock I suggest taking a look at the MasterLock # 1480DAT for 2" hitches and MasterLock # 1469DAT for 2-1/2" hitches.

  • Weight Capacity of Hitch Lock part # e99039
    Our hitch locks have the same capacity as a standard hitch pin. If you are worried about strength you could go with a stainless steel model like part # e98882, but since your hitch capacity is 6,000 pounds, part # e99039 would be fine. It takes quite a bit of force to shear a 5/8 pin. Usually the ball will shear off or the ball mount bend before anything else fails. I have not heard of anyone breaking any of hitch pins or hitch locks.

  • Hitch and Coupler Lock Recommendation for 2000 Chevy Tahoe and 1994 Coleman Tent Trailer

  • Trailer Hitch Receiver and Coupler Lock Compatible with Weight Capacity of BlueOx SwayPro
    I have a locking hitch pin solution for you, but I confirmed that the locking hitch pin in the Receiver and Coupler Lock Set # e99039 is rated for use with Class III and Class IV trailer hitches. Since most Class IV trailer hitches have a capacity of 10,000 pounds, this is the capacity they list for the receiver lock # e98880 in the Lock Set # e99039. I recommend using the Tow Ready Trailer Hitch Receiver Lock, Padlock Style for Class III, Class IV, and Class V Trailer Hitch Receiver...

  • Trailer Hitch with Best Ground Clearance for 2008 Honda Element EX AWD
    All of the trailer hitches available for your 2008 Honda EX are going to have pretty similar ground clearance measurements but your best option will be with the Draw-Tite Class III # 75659. The 2 inch receiver on this hitch will pretty much sit right up against the bottom of the rear bumper on your Element (see attached image). This Class III hitch will use existing holes in the vehicle's frame for a no-drill installation and it has a 3,500 pound towing weight capacity and a 350 pound...

  • Can a High/Low Adapter be Used with a Hitch Extender for Flat Towing
    I do have a solution for you, but using an extender with a high-low adapter would be using 2 adapters and is not advisable. Hitch extenders reduce the weight rating of your hitch by 50% and will also cause more movement not to mention the torque that will be on both adapters when you are making a turn. Instead what you can do is swap out your current hitch mount tow bar, like the Blue Ox Alpha # BX7380 for a coupler mount tow bar like the Blue Ox Acclaim # BX4330. This allows you to...

  • Recommended Class III Trailer Hitch Receiver For A 1999 Toyota RAV4
    For your 1999 Toyota RAV4, the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C13524 is a confirmed fit and is a great hitch that is easy to install and has a nice sturdy square tube design. The rated towing capacity of the hitch is far above your vehicle's rated towing capacity as you stated, but you will be much happier with a Class III hitch. The class 1 hitch will greatly reduce your ability to use accessories and will significantly reduce options for even a ball mount....

  • Trailer Hitch and Bike Rack Recommendation for a 2006 BMW X5
    I recommend the Draw-Tite Trailer Hitch for the 2006 BMW X5, item # 75492, which has a 6,000 pound towing weight capacity and a 600 pound tongue weight capacity. The highest capacity hitch is always the way to go when possible, for safety and versatility for future needs. At first look the Curt Trailer Hitch for the 2006 BMW X5, item # C13162, seems to be an easier installation but if you review the instructions for each, I believe, you will see that the Draw-Tite model is just as easy...

  • Comparing Reese Weight Distribution System With Equal-i-zer Weight Distribution System
    The Reese Steadi-Flex # RP66558 and the Equal-i-zer # EQ37060ET systems are both very good and will work well with your 2011 Ford F-150 and your 17SD Casita trailer. The major differences are in the tilting design of the head, the trunnion bars, and the friction points. The Equal-i-zer system uses the traditional washer stacking design for the head angle, where the Reese system uses a serrated washer design so no additional washers or stacking is needed. The trunnion bars are shaped...

This system has a total tongue weight range of 600-1200 lbs. The total tongue weight is the loaded tongue weight of your trailer along with any cargo behind the rear axle of your truck. The Reese Straight-Line uses hot rolled spring trunnion bars along with cams to keep your trailer straight. This is the only system that actually...

  • Which Coupler Lock Set is Best for Use with Atwood Trailer Coupler 81911
    The Atwood Trailer Coupler 81911 that you have on your A-frame trailer can be locked in two ways, by securing the latch and by blocking entry of a hitch ball. The latch mechanism on the top can be locked with an item like the Dead Bolt # e98884. (This latch lock is one of the two locks included in part # e99039, which is our reference for the CT Johnson part RHC32.)
