Expert Answers about Mercedes-Benz GLS


  • Parts Needed to Install Brake Controller in 2020 Mercedes Benz GLS
  • If your 2020 Mercedes Benz GLS has the factory 7-way you can easily install the Redarc Tow Pro Elite part # RED44FR with just the install harness part # 3066-P. If you do not have a 7-way you'd have to install a 4-way like part # 119250KIT with the 7-way adapter # ETBC7 so that you could install a wireless brake controller like the Curt Echo Mobile # C51180. To find someone to do the install best option is to find a local mechanic to you with a good reputation and let them tackle the...

  • Recommended Snow Tire Chains for a 2020 Mercedes-Benz GLS with 275/55-19 Tires
  • I think you meant 275/55-19 and in which case the Konig Premium Self-Tensioning Snow Tire Chains part # TH02230K77 are what you're are going to want to use on the rear wheels since they don't go around the inside of the tire so there will be no tire clearance issues. These are also the same chains recommended by Mercedes. They are super easy to install once you get them setup the first time and there is very minimal contact with the vehicle.

  • Can Brake Controller Power Wire Circuit Amperage of 2018 Mercedes Benz GLS be Increased
  • To increase the amperage rating of the brake controller power circuit of your 2018 Mercedes GLS for the # C51170 you'll have to bypass the vehicle wiring by running 10 gauge wire like part # 10-1-1 (sold by foot) from the black wire of the controller directly to the vehicle battery. 15 amps really isn't enough for any brake controller to activate trailer brakes.

  • Bike Rack Recommendation for 3 Mountain Bikes and 1 Cruiser
  • Actually, the Hollywood Racks Destination platform-style bike rak you'd looked at, part # HR4000 would be a great choice for carrying the bikes you described at a pretty reasonable price. If you click the provided link, you can see my buddy Hayden demonstrating the rack. As you can see in the video, 4 bikes of varying sizes and types fit pretty well on the rack. When loaded, there will be about 8 inches separating each bike, and you'll want to alternate the direction of every other loaded...

  • Roof Rack for 2 Sets of Hullavators on 2017 Mercedes-Benz GLS
  • Two sets of Hullavators # TH898 require at least 57" of bar space and a high weight capacity for roof rack weight plus kayak weight plus 80 lbs of Hullavator weight. So, yes, they will fit on 60" cross bars. The Thule Roof Rack that fits your car consists of 53" Thule Wingbar Evo Crossbars # TH711420 and Thule Evo Raised Feet # TH710401. Unfortunately, that does not fit two sets of Hullavators and I do not recommend using larger bars since Thule specifically adapts the selected load bar...

  • Wireless Brake Controller Recommendation for 2022 Mercedes Benz GLS
  • We have the Curt Echo Mobile Wireless brake controller part # C51180 which would work great with your 2022 Mercedes Benz GLS 450 that has a factory 7-way. Basically you'd just need to plug this into the 7-way and once synced to your smart phone would be ready to go without any wiring. This is a proportional brake controller too which means it senses how hard you are applying the vehicle brakes and applies the same to your trailer.

  • Brake Controller Recommendation for 2019 Mercedes Benz GLS450
  • I have a great brake controller option but we don't have the Redarc you referenced confirmed as a fit actually. Instead we have the Curt Echo In-Line wireless brake controller part # C79DR as a fit that I would recommend. The reason THIS controller is a fit is due to it's unique design which is very universal. It installs by plugging inline with the 7-way of the 19' GLS450 and once synced to a smart phone is ready to tow with. No difficult wiring or anything else needed. We don't have...

  • Curt Class III Receiver Hitch Towing Capacity for 2017 Mercedes-Benz GLS
  • With any towing setup you are limited by the lowest rated component as the overall capacity as it would be what fails first. So your 2017 Mercedes Benz GLS 450 would be limited to whatever the owners manual states regardless of what hitch you have installed. So that begs the follow up question...why do we offer hitches rated for more than the vehicle? The answer to that is our manufacturers design a hitch to fit the vehicle and then do the best they can to make it as strong as possible...

  • Recommended Ball Mount For 2018 Mercedes-Benz GLS
  • Based on the diagram you provided it appears you will need a ball mount that is not more than 7-1/2" long from the center of the hitch pin hole to the center of the ball hole, and has between a 2-3/4" drop and a 2" rise. For a ball mount that falls in that range we have the Curt Towing Starter Kit for 2" Hitches - 2" Ball - 3/4" Rise, 2" Drop - 7.5K # C45534 which measures 7-1/2" from the center of the hitch pin hole to the center of the ball hole, and has either a 2" rise or 3/4" drop....

  • How Can I Transport 2 Electric Bikes On The Back Of My Airstream Travel Trailer?
  • I have exactly what you are looking for, however, the Kuat Envy 2.0 Base 2 Bike Carrier # BA22B will not work as this is not rated for RV / Motorhome use. Bike racks that are RV/Motrhome-rated are built to withstand the extra bouncing that occurs on the back of a motorhome or travel trailer. Your best option is the Swagman E-Spec Bike Rack for 2 Electric Bikes - 2" Hitches - Frame Mount # S94FR. The weight capacity is 70lbs per bike and it clamps onto the bike frame, making it a great...
