  • Trailer Hitch and Wiring for a 2015 Mercedes GLK250
  • There is one trailer hitch that fits the 2015 Mercedes GLK250. It is Curt trailer hitch # C13155. But this hitch does require drilling for installation. There aren't any no-drill options. I have included a link to the instructions so you can see how the hitch installs. There is no welding required. If you decide to go with this hitch and will be doing some towing the recommended ball mount is # C45030. For a 1-7/8 inch ball use # 19260, for a 2 inch ball use # 63845, and for a 2-5/16 inch...

  • Recommended Wiring Harness For 2015 GLK-350 Base
  • The Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236 is not confirmed to fit your 2015 Mercedes-Benz GLK-350. It is a confirmed fit for the 250.

This wiring harness uses zero-contact-interface sensors, so there is no wire splicing, but it will require a power lead from the battery.

  • Hitch and Bike Rack Recommendation for 2013 Mercedes GLK350
  • For your 2013 Mercedes GLK350 the best hitch option is the Draw Tite part # 75774 as it will give you the most concealed look. For a bike rack I really like the Hollywood Racks Destination Bike Rack # HLY94FR. This is a platform bike rack that only weighs 20 lbs. The biggest drawback to platform bike racks has always been the weight of them, but with this rack you get the best of both worlds. The preferred attachment style with the lighter weight.

  • Ball Mount and Trailer Connector Adapter Recommendation for 2014 Mercedes GLK 350

I have attached a help article on finding the correct ball mount. You will also want to know the weight of the trailer you are towing. This is important to make sure you do not exceed the towing...

  • Trailer Hitch and Wiring for a 2014 Mercedes GLK 250 Bluetec
  • First, for a trailer hitch that fits your 2014 Mercedes GLK 250 BlueTec there is one option; Curt trailer hitch # C13155. And for a trailer wiring harness I recommend # C59236 since it is designed to work with 2 or 3 wire electrical systems and PWM (pulse width modulation) systems so pretty much all scenarios are covered. A trusted mechanic or RV dealer with a service center could perform the installation for you. When using the hitch for towing you can use ball mount # C45030. For a...

  • Roof Mount or Hitch Mount Cargo Carrier for a 2014 Mercedes GLK 350
  • The benefit of getting a trailer hitch is that you can use it for other things such as towing if needed, bike racks, cargo carriers, and other accessories. With a roof bag it only has one function and you will have an item on the roof that you have to load and unload which can be difficult on an SUV or taller vehicles in general. And if you do not take the necessary precautions first, a bag could scratch the paint. With a hitch mount carrier there is some extra expense but it is the safer...

This model features a digital display, 3 boost models and continuous diagnostics that will alert you to any potential issues. The Prodigy P2 is known for its reliability and...

  • Choosing Correct Ball Mount for 2014 Mercedes Benz GLK 250 BlueTec w/ Factory Hitch
  • I would imagine that Mercedes puts a Class III hitch on that vehicle as the factory option. You can confirm that by measuring the INSIDE dimension of the receiver opening. If it measures 2 by 2 inches, it's a Class III. If it's 1-1/4 by 1-1/4 inches, its a Class I or II. The sticker on the hitch should tell you which. Both the ball mounts you mentioned could be used in a Class I or II hitch, as long as the capacity of the hitch or the ball mount isn't exceeded. If you have the Class III...

  • Recommended Weight Distribution System For R-Pod Trailer Behind 2015 Mercedes-Benz GLK 250
  • For your application, I recommend the Fastway e2 Weight Distribution w/ 2-Point Sway Control - Trunnion - 4,500 lbs GTW, 450 lbs TW # FA92-00-0450. This system has no minimum tongue weight and a max total tongue weight of 450 lbs.

  • For your 2011 Mercedes GLK350 the Draw-Tite hitch # 75774 and discontinued Hidden Hitch model 87636 are going to be identical (except for the name). The installation of these 2 hitches takes less time and thus installation is easier than the Curt hitch # C13142 which uses different attachment points on the vehicle.
