I am planning on taking a hitch for my 2015 GLK250, and need to be absolutely sure that it will fit easily, without any drilling or welding. Please let me know ASAP.

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 ball use # 63847. For a pin and clip use # PC3.

And for trailer wiring I recommend the new Curt harness # C59236. It will provide a 4-Way flat connector at the back of the vehicle. I have linked a review video for you.

If you will be using the hitch for an accessory such as a bike rack or cargo carrier Curt says you have to use stabilization strap # 18050 when using this hitch for any non-trailer load (such as a bike rack or cargo carrier) per their warranty requirements.

If you do not have the brake controller already then, I actually recommend going with the Curt Echo Mobile #C51180, for a few reasons. First, it does not require that the 7-Way on the vehicle has the brake output circuit so you would not have to add…

Brake systems are not dependent on the hub bolt pattern. So you can use the Electric Trailer Brake Kit #AKEBRK-7-SA for 12 inch hub/drums or #AKEBRK-35-SA for 10 inch hub/drums. Then use #10-1-1 wire sold by the foot for your brake magnet wiring.…

If the trailer wheels scrubbed (dragged and scrapped the ground instead of rolling) when jack knifed then it could have thrown something out of alignment or damaged something. First, inspect the suspension. Look for any elongated holes where…

I did some checking and the hub/drum we offer that will work for you is the part #8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS…
