Expert Answers about GMC Envoy


  • Weight Distribution System for Chaparral Horse Trailer Towed By 2004 GMC Envoy
  • The first step in choosing a weight distribution system is to definitively identify the fully-loaded and ready to tow tongue weight of the trailer. There are a few methods of doing this, as you can see by clicking on the link I provided. Knowing the exact tongue weight is a crucial step in choosing the correct system for your application. If you choose a system that does not have a high enough capacity, the system will not be effective and could be damaged. Choosing a system whose capacity...

  • Towing Mirrors Recommendation for 2004 GMC Envoy XUV
  • For your 2004 GMC Envoy XUV you will need to use a universal style mirror. You could use the CIPA Universal Strap-On Towing Mirror Review, part # 7070, like you referenced, it would install on your 2004 GMC Envoy XUV. Or you could use the Cipa Dual-View Clip-on Towing Mirror, part # 11953. Both of these mirrors would work well for you, but if it was me I would buy the # 11953 because it has two mirrors per side for increased visibility as opposed to the one mirror per side that the #...

  • Recommended Towing Mirrors For 2009 GMC Envoy Denali
  • We do not have a custom mirror that is designed to fit your 2009 Envoy, but we do have another option. I recommend the K-Source Universal Towing Mirror, part # KS3891. This will clip on to the edge of your mirror and will fit most mirrors that measure 4-1/2 to 11-1/2 inches tall.

  • Parts Recommendation to Flat Tow a 2003 GMC Envoy
  • Yes, as long as the owners manual of your 2003 GMC Envoy says it's okay to flat tow your vehicle you can use your Roadmaster Falcon Tow Bar part # RM-522 with your RoadMaster BrakeMaster # RM-9100. Only additional part you would need regarding the braking system would be the seat bracket part # RM-88181. Additionally you will need a base plate kit, for that you would want the Roadmaster Base Plate kit part # 3108-1. For safety cables you can use # RM-643. The coiled design helps keep...

  • Installing Tekonsha Prodigy P3 Brake Controller on 2003 GMC Encoy with Factory 7-Way
  • If your 2003 GMC Envoy is equipped with the factory 7-Way connector at the rear bumper, then all the needed wires for a brake controller are run, but there is not a factory plug present that will accept a plug-in adapter. In order to install a brake controller like the excellent Tekonsha Prodigy P3 # 90195 that you referenced (great choice), you will just need to connect the brake controller wiring to the wiring present under the dash. The factory wires should be labeled according to...

  • Watersport Carrier Recommendation for a 2006 GMC Envoy with Factory Roof Rack
  • The Rola Multi-Pivot Watercraft Carrier was designed to fit the specific shape of the Rola Sportz crossbars or a certain size T-slot on top of the bars. It has not been tested on other bars so I cannot say if it will fit or not. What I recommend is to use some foam blocks, like # RL100K10. These blocks are universal and can fit square load bars, round crossbars, factory bars and naked roofs. They also include bow and stern tie downs.

  • Recommendation for a Towing Mirror to Fit a 2008 GMC Envoy SLE
  • The K-Source Universal Towing Mirror, # KS3891, would be a great option for a towing mirror on your 2008 GMC Envoy. It fits most mirrors 4-1/2 to 11-1/2 inches tall and mounts on either of your factory side mirrors to increase visibility. The ratcheting strap system offers easy installation and holds the mirror snug to reduce vibration. Custom towing mirrors are only made for full size trucks, vans and SUVs so universal mirrors are the way to go for your vehicle. I have attached a short...

  • Weight Distribution and Brake Controller for Towing Pop-Up Camper with 2006 GMC Envoy
  • There are a few primary rules of thumb to determine if a weight distribution (W/D) system is necessary. If the fully loaded and ready to tow weight of the camper is more than half the weight of the tow vehicle of if the rear of the vehicle squats more than a few inches when the camper is hitched to your Envoy, using a weight distribution system would be highly recommended. Also, take a look at the hitch on your vehicle. The hitch will typically have a sticker stating the towing and the...

  • Tow Mirror Recommendation for 2005 GMC Envoy SLT
  • I have a great tow mirror solution for your 2005 GMC Envoy but we do not have any slip-on style mirrors that fit like the CIPA mirror you mentioned. Instead you'd want a set of clip on style mirrors like the K-Source Set part # KS3891-2. These install easily by clipping to the lip around the edge of your mirror housings and are very secure. This is a set as you'll want the extra viewing angle on the passenger side as well.

  • Recommended Towing Mirrors for 2007 GMC Envoy
  • The CIPA Clip-On Towing Mirror # 7070 referenced in your question is a universal towing mirror that will work well on your 2007 GMC Envoy as long as it has the lip or ridge running around the edge of the factory mirror. With this in mind, I instead recommend taking a look at the K-Source Universal Towing Mirror # KS3891. Like the CIPA model, this will work great with the factory mirrors on your GMC Envoy, but will attach to the mirror with a ratcheting system compared to the buckle type...

  • Weight Distribution for 2008 GMC Envoy Denali and 5,600 Pound Travel Trailer
  • To choose a weight distribution system you will need to go by the total tongue weight of the set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that the weight of anything loaded behind the rear axle of the tow vehicle. On a trailer that weighs up to 5,600 pounds the tongue weight will likely be 560 to 850 pounds which is 10 to 15 percent of the gross trailer weight. If you keep the total tongue weight under 800 pounds then...

  • Recommendations for Backing Trailer With Friction Sway Control Unit Installed
  • Although it is not mentioned in the instructions, it is regarded as a good practice to disengage the friction sway control # 83660 before backing the trailer, which is why we specifically mention it in the product description. If the trailer should jackknife during backing, the sway control unit would be damaged. Because of this, I would agree with your dealer and would join him in urging you to disengage the unit before backing. You will also want to disengage the unit when towing on...

  • Can Locking Hitch Pin part # C23519 Be Used With Travel Trailer
  • The Trailer Hitch Receiver Lock # C23519 that you referenced is designed for exactly what you are looking for so it would work well. It is a hitch pin with a lock on the end that would work well with your travel trailer. Since hitch pins don't bear any of the weight of the trailer, they aren't rated in terms of weight capacity. The trailer's tongue weight puts so much pressure on the hitch that the ball mount gets bound up in the hitch. Meaning the hitch pin does not ever take any of the...

  • Brake Controller Recommendation For 2003 GMC Envoy
  • The most popular brake controller we offer is the Tekonsha Prodigy P2 Brake Controller, part # 90885. This is a proportional brake controller and activates the brakes on your trailer in direct proportion to the brakes on your towing vehicle. I have attached a link to a video that shows how a brake controller is installed on an Envoy you can check out. If by chance you do not have the connector at the rear of your vehicle let me know and I can make some recommendations for the components...

  • Installing Dexter Predator DX2 Brake Controller on 2008 GMC Envoy
  • As long as your 2008 GMC Envoy is equipped with the factory 7-Way connector there will be blunt cut wires located inside the vehicle on the driver's side under the instrument panel to which your Dexter Predator DX2 Brake Controller # 58-8 can be directly wired. Based on my research there should be a red/black wire that connects to the black (12V power) wire on the controller, a white wire that connects to the white (ground) wire on the controller, a light blue/white wire that gets connected...

  • Recommended Railed Cargo Carrier for 2005 GMC Envoy XL
  • I recommend the 24x60 Folding Cargo Carrier, part number # e98874. The large size and folding ability make this carrier a great option. Where are your reverse lights located? If they are on the the corner of the vehicle, they most likely will not be obscured by the carrier. If they are on the liftgate, they probably will be. You would experience this issue with any cargo carrier, especially once it is loaded. We offer a Cargo Carrier Light Kit, part number # e98943-44LED that you...

  • How To Help With Rear Sag While Towing With a 2007 GMC Envoy and Quality S WDH
  • It does sound like the spring bars that you have are underrated for your trailer which is then not allowing the tongue weight to be transferred to the front of the tow vehicle which results in too much sag. As we do not carry the Quality S Weight Distribution System, I unfortunately would not have the correct replacement spring bars for you nor am I aware if they are even available. That said, the most cost effective option you have to help get rid of the sag would be to use the Firestone...

  • Brake Controller Recommendation for a 2002 GMC Envoy
  • To install a brake controller in a 2002 GMC Envoy there isn't a quick plug-in harness confirmed to fit the vehicle like the # C51432 that you referenced. There are 4 blunt cut wires under the dash that you will need to wire the brake controller to. To install the Curt Venturer part # C74VV you will also need the # C51515. Check out the video I attached that shows a similar brake controller being installed in a GMC Envoy of the same generation as yours to see how it installs.
