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...

  • 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...

  • Getting Keyed Alike Locksets for Hitch, Coupler and Cable Locks
    Yes, you can get all of the locks you have mentioned keyed alike as long as you order from our Keyed Alike locks page. If you order all the locks you need at the same time they will come keyed alike. If you decide you need another lock keyed the same later you can call our customer service line at 1-800-298-8924 and request a lock, as long as it is on our Keyed Alike locks page, with the same key by giving them the key number you have.

  • 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...

  • 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.) But please note that this latch lock has a center span of only 1/2-inch; the coupler latch on your # 81911 requires a...

  • 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...

  • 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...

  • 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 # BX7365 for a coupler mount tow bar like the Blue Ox Acclaim # BX4330. This allows you to...

  • Recommended Weight Distribution System And Suspension Enhancement For 2012 Ram 1500
    For your 2012 Ram 1500, a weight distribution system with sway control will help a great deal. To determine the best system for you, we need to look at the total tongue weight which is the loaded tongue weight of your trailer plus any cargo behind the rear axle of your truck. This total tongue weight will help us find a system that has the actual total tongue weight in the middle of its range for best results. For your application I recommend the Reese Strait-Line Weight Distribution...

  • Can a Bumper Mounted Trailer Hitch be Used to Tow a 5X8 Trailer with a 2005 Chevrolet Colorado
    As long as you stay within the manufacturers tongue weight and gross trailer weight ratings, see bumper and owners manual, you will not have a problem towing with the Curt 2 inch Bumper Hitch, 5,000 lbs GTW, item # E-3S. A better solution for your towing needs would be the Draw-Tite Class III Trailer Hitch, item # 75607, which is designed specifically for your 2005 Colorado.

  • Recommendation for Keyed Alike 2 Inch Hitch Lock, 1-1/4 Inch Hich Lock, and Coupler Lock
    For the locks that you are needing, I recommend going with the etrailer Trailer Hitch Receiver & Coupler Lockset # e99039 that you mentioned. 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. This chrome 1-1/4 inch receiver lock will come with a quantity of 1, so you will just need to order two. Since these locks are all from...

  • Recommendation For Locks To Prevent Theft Of A Camper Trailer
    If you are wanting to lock the trailer to your 2002 Isuzu Trooper and you have a 2 inch hitch receiver, I would recommend the etrailer Trailer Hitch Receiver And Coupler Lockset, part # e99039. This is a set of locks that will lock the ball mount to your tow vehicles 2 inch hitch and also lock the trailers coupler to the hitch ball. Both of the locks can be keyed alike, so only one key is needed for both locks. Locking your trailer at both connections will add time when somebody is...

  • How Can I Get Three Different Locks Types Keyed Alike?
    In order to complete this process correctly, you will need to place all of the different locks on the same order. They need to be products with the same brand or manufacturer. Under each individual product, choose the "keyed alike" option before adding the product to your cart, all the products in your completed "cart" will be locked and unlocked with the same key. For example, if we use all etrailer products such as the etrailer Trailer Coupler Lock # e98888 and etrailer Trailer Hitch...

  • 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....

    The Pin and Clip For Class 3, 4 and 5 Trailer Hitch Receivers, item # PC3, is the pin needed to install a ball mount in a Class 3 or larger 2 inch receiver.

You do not need to bend or manipulate the exhaust in any other way and when the install is complete you will return the exhaust to its factory position.
