Ask the Experts about this etrailer Trailer Coupler Locks

  • 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 I Get Keyed Alike Locks For My Different Hitches and Trigger-Latch Coupler?
    Yes! So you would need the etrailer Hitch Receiver and Coupler Lock Set # e99039 which comes with a 2" hitch pin lock and a 1/2" coupler latch lock. Then you can also get the etrailer 1-1/4" hitch lock # e98879. If you select "Keyed Alike" and they are all in the same purchase order, then we will put keyed alike lock cores into all of them before sending them out.

  • 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. You may save a couple dollars this way.

  • How To Order Stainless Steel Hitch Locks and Coupler Locks to be Keyed Alike
    For stainless steel coupler lock and hitch receiver lock that can be keyed alike, I would recommend the etrailer brand locks. They offer the etrailer Stainless Steel 2 Inch Hitch Receiver Lock, part # e98882, which will fit most 2 inch hitch receivers, and has an inside width of 2-5/8 inches. For coupler locks they offer the etrailer Stainless Steel 7/8 Inch Span Coupler Lock, part # e98890, which has an inside width of 7/8-inch, and the etrailer Stainless Steel 1/2 Inch Span Coupler...

  • Is etrailer e99039-9 Hitch and Coupler Lockset Available for a Class V 2-1/2 Inch Hitch
    Unfortunately, we don't offer a kit like the # e99039-9 for a 2-1/2 inch class V receiver. This being said, you can get the same coupler lock, part # e98884, coupler lock # e98881 for a 2-1/2 inch hitch and the # e98900 storage bag separately. For the locks, just choose the 'keyed alike option' from the drop down menu.. We don't offer the alignment collar in a class V compatible version yet.

  • 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 then...

  • Recommended Parts Needed To Tow a Trailer with a 2018 Subaru Forester
    Yes, the etrailer Trailer Hitch Receiver part # e98839 is a great option for a 2018 Subaru Forester and a direct fit. It can then be used with the Curt T-Connector Vehicle Wiring Harness part # C56040 to activate the trailer lights. I'd then recommend using the etrailer Ball Mount Kit part # 989900 to complete your setup. This would be all that is required though you could add the etrailer Trailer Hitch Reciever and Coupler Lockset, Alignment Collar, and Bag part # e99039-9 for locks as well.

  • Recommended Weight Distribution System For Grand Design Imagine 2950RL Trailer
    For your 2016 Ford F-150, I recommend the Reese Strait-Line Weight Distribution w Sway Control - Trunnion Bar - 12,000 lbs GTW, 1,200 lbs TW # RP66074. 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 actively...

    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...

    The Curt Class III Trailer Hitch, item # 13328, will fit on both the 2004 and the 2005 models of the Acura MDX. The note about fascia trimming concerns an extra fascia piece that may be installed on some vehicles.

The factory sized spare tire will be lowered for installation and reinstalled after installation is complete. I have not seen the park distance control you are referring...

  • 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.

  • Ball Mount, Ball, Sway Control, Locks, Spare Tire for Hallmark Trailer and 2006 Toyota Highlander
    First, to determine the correct ball mount you can follow the help article I have linked. It is important to measure ahead of time to get a ball mount with the right rise or drop needed to tow the trailer level. Or you can go with an adjustable ball mount such as # MT70067 which is great for more than one trailer or if you might be towing something different in the future. It has a maximum rise of 8 inches and maximum drop of 10 inches. For a 2 inch ball that is compatible with this ball...

  • 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...
