Expert Answers about GMC Yukon XL


  • Parts Needed to Flat Tow a 2006 GMC Yukon XL
  • There are several different base plates available depending on the model 2006 GMC Yukon XL you have. For a 1500 or Denali, use XL Style Base Plates, # 199-5. For a 2500, use # 3115-1. From the research I did, the Yukon has a curb weight of up to 5,770 pounds. With gear loaded in it, it could easily exceed 6,000 pounds. For this reason, I recommend going with a 10,000 pound capacity tow bar like the Roadmaster Blackhawk 2 All Terrain, # RM-422. I have included a link to the installation...

  • Parts Needed to Flat Tow a 2015 GMC Yukon XL Denali Behind a Motor Home
  • To keep a maintenance charge on the battery I recommend using a harness such as # RM-146-7 with the tow bar wiring you will be using so that you can install a charge line kit, # RM-156-25, from the front of the truck to its battery. The charge line kit uses the 12 volt power pin on your motorhome's 7-way to provide a maintenance charge to the battery on your 2015 GMC Yukon XL. It won't charge a dead battery but it will keep the truck's battery from dying while you're towing it. We do...

  • There are a couple of small items you may need when installing the P3 Brake controller on your 2010 GMC Yukon with factory trailer wiring package. We have an informational article that details the installation and location of wires on your vehicle that you will need, see link. The only parts that you might need are the M6-1.0 nut, # 185916, and M8-1.25 nut, # 185917, to secure the wires to the power studs at the front of the power distribution box if that step was not completed at the...

  • Replacement 4-Pole Wiring Harness for 2005 GMC Yukon XL
  • You probably could rig your damaged wiring harness in the way you describe, using diodes to keep the circuits separated, but I suggest just replacing the harness with a 4-pole set-up like # C59496. This is a hardwired harness with a substantial current capacity of 2.1 amps per stop/turn circuit and 7.5 amps for the tail lights. The risk in doing what you describe is that the wiring/circuits you would be accessing for signals may not be able to provide the required current for the trailer...

  • How to Reduce Sway of Towable Ice Fishing Shack Towed By 2011 GMY Yukon XL
  • Typically, the best way to combat trailer sway is by using a weight distribution system with an integrated sway control component but from what I saw online, your fish house has a very unique trailer tongue that wouldn't be well suited for a weight distribution system. The Timbren # TGMRYS4 helper springs would help somewhat with sway, but not to a huge degree. I'd replace the factory anti-sway bar with a larger one such as the Roadmaster # RM-1109-168. A larger diameter anti-sway bar...

  • Recommended Hitch and Wiring Harness for a 2003 GMC Yukon XL
  • I would be happy to help you set up your 2003 GMC Yukon XL to tow your 2016 Forest River SALEM CRUISE LITE 195BH. Without knowing what your current hitch's capacity is I can not say for certain you don't need to replace it. However, if you do want or need to replace it I recommend the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C13422. This is a custom fit hitch that bolts onto your Yukon and has a 2" receiver opening. It has a maximum gross trailer weight of 6,000 lbs and...

  • Best Transmission Cooler, Cold Air Intake, and Tuner for 2015 GMC Yukon XL 5.3L Towing in Mountains
  • All of our transmission coolers are actually designed to be used in addition to your OEM cooler. For the 5.3L V8 on your 2015 GMC Yukon XL (excluding 323 c.i.) the best option we have is the Derale # D13503. These coolers aren't necessarily vehicle specific. You just need to make sure that you have enough room under your hood for it. This cooler measures # 11" wide x 8-3/4" tall x 7/8" deep. I have linked a helpful article on transmission coolers that you can reference for the best place...

  • Parts for Lugged Hubs on a Mobile Home Axle with 15123 inner and 25880 Outer Bearings
  • It sounds like you have a spindle that uses the Inner Trailer Hub Bearing, item # 25580, that has a 1.750 inch inner diameter. The outer # 15123 bearing has a 1.250 inch inner diameter. I would check the seal surface on the spindle to be sure that it matches the # RG06-070 seal inner diameter of 2.250 inches. Many times mobile home axles use non- standard parts so careful measurement of all of the parts is required. If all of these dimensions match, then you will need to determine whether...

  • For your application, I would recommend the P3 Proportional Brake Controller, item # 90195 and wiring harness # 3015-P, which is compatible with electric over hydraulic braking systems. The # 3015-P will plug in under the dash on your Yukon XL. I have included an article on installation of a brake controller on 1999-2006 GM trucks and SUV vehicles. For a hard wire connector you can use the 7-Pole, RV-Style Trailer Socket, item # PK12-707E, along with the # PK12711U mounting bracket or...

Both options include the required mounting hardware. I have linked representative installation videos for this brake controller in both a Silverado and a Yukon XL.

  • Hitch and Weight Distribution for 2002 GMC Yukon XL Towing 8600 lb Travel Trailer
  • For a receiver hitch, I'd recommend the Curt Class IV, part # 14080 which has a 10000 lb towing/1000 tongue weight capacity or 12000 towing/1200 lb tongue weight capacity if used with a weight distribution system. These capacities would be ideal for the travel trailer you spoke of. If the 8600 lb figure you mentioned represents the travel trailer weight when it's loaded up as you'd normally have it when towing, your tongue weight will be in the 800-1200 lb range. I'll link to an article...

  • What Ladder Can I Use to Access My Yakima LockNLoad # Y05048 on My 2008 GMC Yukon XL?
  • I have a solution for you. I reached out to Rhino-Rack, and they could not confirm for sure that the mounting brackets of the Folding Ladder for Rhino-Rack Pioneer Platform Racks - Aluminum # RRRAFL-RUFLB will be able to fit the channels on your Yakima LockNLoad # Y05048. With that information, the safest bet is to go with a telescoping ladder like the Thule Telescoping Ladder for Vans - 9 Steps - 8-1/2' # TH301404. The reason why it is better to go with the Thule Telescoping ladder over...

  • What Parts do I Need for a Complete Roof Rack System for a 2016 GMC Yukon XL?
  • I have a great solution for you. Unfortunately, the Yakima CoreBar Crossbar System for Retrax XR Series Tonneau Covers are only installable on truck beds. It will not fit on your flush factory rails on your 2016 GMC Yukon XL Denali. With that being said, for a great roof rack with a 220-pound weight capacity on your vehicle, I recommend the following roof rack setup: - Rhino-Rack Vortex Aero Crossbars - Aluminum - Black - 59" Long - Qty 2 # RRVA150B-2 - RCH Legs for Rhino-Rack Crossbars...
