2008 Chevrolet Avalanche Questions and Answers


  • Installing an Electric Trailer Brake Controller on a 2008 Chevy Avalanche
  • If your 2008 Chevy Avalanche came with a factory installed 7-Way trailer connector, it will have wiring for the brake controller under the dash. It will not have a port you can plug into, but the wiring will be already ran and you just have to make 4 connections. The wire bundle will be located under the dash, to the left and above the brake pedal. The bundle will be held together with a white tag. On the tag, the functions of the wires should printed. On the tow package wiring from...

  • Alternate Wiring of Peak Performance Wireless Back-Up Camera # PKC0RB
  • Installing the transmitter on the front trailer wall might work for you, but it will depend on how much line-of-sight interference there is between the transmitter and the monitor. You should do your best to keep the transmitter out of the elements, so mounting it on the inside of the trailer or other protected area is best. Variables such as the thickness and composition of the trailer wall and whether or not anything will be in the truck bed to interfere with the signal from the transmitter...

  • Fuse Position to Activate Accessory Power and Brake Control Power on a 2008 Chevy Avalanche
  • If my memory serves me right the fuse positions for the auxiliary power posts under the dash on a 2008 Chevrolet truck or SUV are the closest two square fuse slots in the front end of the power distribution box, see photo link. The best way to test those power posts is to use a circuit tester, item # 3808 if needed. Ground the lead from the tester and touch each power post independently. If the tester lights then the fuse is in the proper location. If not a square fuse should be inserted....

  • Installing a Prodigy Brake Controller on a 2008 Chevy Avalanche
  • Your brake controller would install just like it would on a 2008 Silverado. We have a FAQ page (see link) that shows the whole installation. We also have a step by step video (see link) that explains the entire process, as well. You will not need a separate wiring harness, the bare leads from the controller will wire directly to the leads under the dash. Please note, the wire colors under the dash and on the brake controller DO NOT MATCH color for color. Both the video and the FAQ page...

  • Is there an Adapter for Towing a Trailer and Carrying a Bike Rack Together
  • The Roadmaster Dual Hitch Receiver Adapter, # RM-077-4, is not for use with any type of trailer - tow bars only. What you need is the CURT Multipurpose Ball Mount, # D210. This ballmount was designed for the application you are describing. It has a tongue weight capacity of 750 pounds. Tongue weight will be the combined tongue weight of the trailer, the bike rack, and the bikes. The gross trailer weight capacity is 5,000 pounds. The reciever portion of the multipurpose ball mount has a...

  • Recommendation for Cooling the Coolant and Transmission Fluid Temperature on a 2008 Chevy Avalanche
  • For the radiator coolant temperature, I recommend adding a supplemental fan or fans depending on how much space you have under the hood. There is no limit to the amount of fans you can have. A pusher fan, mounted in front of the radiator pushing air through it, would be the most efficient (provided that the factory fan is mounted on the same side and pushes air through in the same direction). A puller fan would be used on the other side of the radiator to pull air through. The largest electric...

  • Weight Distribution Recommendation for a 2008 Chevy Avalanche Towing a 7,900 lb Trailer
  • Before we choose a weight distribution system, we will want to make sure your 2008 Chevrolet Avalanche can handle the tongue weight of your trailer. You mentioned that your tongue weight capacity was 600 lbs. Many times trailer hitches will have two weight capacities listed, a weight carrying capacity and a weight distribution capacity. The weight distribution capacity is often higher than the weight carrying capacity, but a weight distribution system must be used. I recommend checking...

  • Is there a 7-Way Adapter that Splits into Two 7-Ways or Should a Junction Box be Used
  • There isn't an adapter that does what you are looking for. I think the junction box idea is the best solution because junction boxes do make things nice and neat and make it easier to troubleshoot. One thing to keep in mind though is to be careful about how much power you are pulling through a set up like that. Most vehicle side wiring and wiring systems are not rated all that high so overloading them is a real possibility. Our most popular junction box is # 38656 but I have also included...

  • What is Meant by the Different Classes of Transmission Coolers
  • Transmission and oil coolers are given class designations since we are in the towing business and those who tow are used to seeing class designations on hitches, ball mounts, etc. The idea is to give a general idea of the cooler's capacity, so if your vehicle has a class III hitch then a class III cooler should be fine. However, since coolers are NOT vehicle-specific you can use as large a cooler as you have space to mount it. There are various types of coolers and they can be either...

  • Light and Wiring Recommendations for Flat Towing a 2008 Chevrolet Avalanche
  • Because the Chevrolet Avalanche vehicles have so much body trim that is plastic, like on the top of the rear bumper and the top of the bedsides, you would need to use the Standard Magnetic Tow Lights, # RM-2120, on the sides of the vehicle near the rear taillights. I believe a better option for your truck is the Hopkins Tow Bar Wiring for the 2008 Avalanche, # HM56103, which will let you connect your RV signal lights to the Avalanche lighting system. This wiring harness plugs inline...

  • Determine Dexter Axle Capacity Based on Diameter
  • I can help you pretty easily identify the axle capacity of the trailer but it will require you to measure the diameter of the axle. Compare the axle diameter to the following list to see what capacity you have: Typical Axle Diameters Based on Axle Capacity - 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter - 3,500-lb Axles: 2-3/8 inch diameter - 6,000-lb - 7,200-lb Axles: 3 inch diameter - 8,000-lb Axles: 3-1/2 inch diameter - 9,000-lb Axles: 4 inch diameter ...

  • Transmission Cooler Recommendation for a 2008 Chevy Avalanche
  • When installing a transmission cooler on a vehicle like the # D13504 on your 2008 Chevy Avalanche you will want to route the fluid first through your factory transmission cooler and then finally through the supplemental cooler before it returns to the transmission. Factory coolers will actually raise (or lower) the transmission fluid to the same temperature as the engine coolant since the coolers are integrated into the radiator. If you were to route the supplemental cooler before the...

  • Installing Tekonsha P3 Brake Controller on 2008 Chevy Avalanche for Use with Trailer
  • The Tekonsha P3 Proportional Brake Controller, part # 90195, works with any tow vehicle, but the wiring harness # 3015-P, is intended for 2003-2006 General Motors vehicles, not for your 2008 Avalanche. Please refer to the three included articles/videos which will show and explain the required wiring. Please note that the center stop light (CHMSL) wire is not necessarily orange in color. The wiring from the brake controller connects to the vehicle as follows: White ground wire connects...

  • Installing Tekonsha Prodigy P3 Brake Controller on 2008 Chevy Avalanche
  • The 2008 Avalanche doesn't have a connector under the dash. The Avalanche will have bare ended tow package wires under the dash between the steering column and the emergency brake pedal. Look for a wiring harness with a white tag hanging from it. There should be 4 or 5 wires in the harness, and they would connect to the pigtail included with the Prodigy P3 # 90195 brake controller as follows: Red/black striped tow package wire to black pigtail wire White tow package wire to white pigtail...

  • Recommended Converer To Separate Wiring On 2008 Chevrolet Avalanche Flex
  • The Vehicle to Vehicle Taillight Converter, # 118158, will work for you. it will take the combined system you said is on your 2008 Chevrolet Avalanche and separate each signal to it's own circuit. I have attached a link to a product demonstration video you can check out. If you experience hyperflashing which can sometimes occur with LED lights requiring much less power, you may need to use Load Resistors like part # P230004A. These would need to be attached to the LED lights. If...

  • Will the Yakima FrontLoader Wheel Mount Bike Carrier # Y02103 Fit on a 2010 Toyota FJ Cruiser
  • I checked fits with both Yakima and Thule and there is not a bike rack that attaches directly to the factory cross bars on your FJ Cruiser at this time. You could use the Yakima Roof Rack, parts # Y00409, # Y03536 and # Y00147 to install the FrontLoader bike carrier on the roof of your vehicle.

  • Troubleshooting No Power to the Trailer Brake Controller on a 2008 Chevy Avalanche
  • There are a couple of connections you may need to make under the hood to finalize the brake controller installation. Under the hood on the driver side, remove the power distribution box lid. Once removed, you will see a ring terminal directly to the right of the power distribution box (between the box and driver side of the truck). There may be some tape holding it in place. Just cut the tape to release the ring terminal. Next, route the wire to the front of the power distribution box...

  • Is the Roadmster Anti-Sway Bar for a 2008 Chevy Avalanche Better than the Factory Bar
  • The Roadmaster rear anti-sway bar, # RM-1109-168, would be an upgrade to the one that is on your 2008 Chevy Avalanche. It will only work on models that came with a factory sway bar and coilspring suspension. The bar also comes with different bushings constructed of Polyurethane which works better than traditional bushings. The steel used in the Roadmaster bar is also an upgrade from the standard steel used in factory bars. I have included a link to the installation instructions for you.

  • Atwood Robofoot Compatibility with a Trailer with Tall Frame
  • If you have a 2 inch diameter jack leg the Atwood Robofoot Automatic Fold-Up Jack Foot # AT81030 should work just fine. The issue you are referring to is not one we are aware of or have had our customers come back and bring to our attention. Another similar product that you may be interested in is the Husky Brute Super Foot # HT31610. I attached a review video for both products for you to check out as well.

  • Location of Factory Tow Package Wire Bundle to Install a Brake Controller on a 2008 Chevy Avalanche
  • On a 2008 Chevy Avalanche with a factory installed 7-Way trailer connector, there will be a wire bundle that is hardwired into the vehicle so it is unlikely that the previous owner removed the wire bundle. Basically, you are looking for a bundle of wires held together with a white tag. This bundle is tucked up under the dash. I have linked a video on a 2013 Avalanche that should help you locate the bundle. Even though it is a newer model the general location and appearance of the wire...

  • Recommended Weight Distribution System For 2002 Sunnybrook Travel Trailer
  • From my research I found the 2002 Sunnybrook CKS26 weighs approximately 5,000 lbs and the gross weight is 7,000 lbs. When choosing a weight distribution system there are 2 important things you will want to know. The Gross Trailer weight (GTW) and the Tongue Weight (TW). You also want to make sure you do not exceed the towing capacity of your 2008 Chevrolet Avalanche or your trailer hitch. The gross towing weight is the weight of your trailer in its fully-loaded ready-to-tow condition....

  • Under the Hood Connections Required to Power a Trailer Brake Controller on a 2008 Chevy Avalanche
  • The 2008 Chevy Avalanche is probably set up like other GM trucks and SUVs in that there are cases where you do have to make some under hood connections to make the brake controller and/or 7-Way trailer connector fully functional. I have included a link to an FAQ article that will help. You need the part near the end titled Finalizing Connections for the Brake Controller.

  • Parts for Installing Weight Distribution on a V-Nose Trailer
  • Reese does have a different bracket available for towers with V-Nose trailers or trailers with boxes on the A-Frame tongue. These brackets, part # RP58305, bolt-on to the side of the frame instead of going over the top. Since they are not Snap-Up brackets, you will have to hitch the trailer, raise the truck and trailer via the trailer jack, attach the chains, then let the jack down.

  • Recommended Suspension Air Bags for a 2008 Chevy Avalanche with Factory Auto-Leveling Option
  • What I recommend is going with the Timbren vehicle suspension # TGMRYS4 (2WD or 4WD)because the hollow rubber springs sit above the axle and they are easy to install. It will also be compatible with your auto-leveling system. Also, the Timbren suspension will offer progressive resistance, meaning they won't change the ride until you load up weight. The weight capacity is 6,000 pounds but don't exceed your Chevy Avalanche's weight carrying capacity. Keep in mind that adding any suspension...

  • Weight Distribution System Recommendation for a 2008 Chevy Avalanche Towing 6,200 lb Travel Trailer
  • The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow. This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached a help article on determining tongue weight for you to check out as well. You will want the loaded tongue weight of your setup to fall right in the middle of the tongue weight range of the system you use. With your dry tongue weight being...

  • How to Choose the Correct Ball Mount for a 2008 Chevrolet Avalanche 4x4 with 18 Inch Wheels
  • To determine which ball mount you will need to tow your pop up trailer with your 2008 Chevrolet Avalanche, you will need to take two measurements. The first measurement is your hitch height. You can find this by measuring from the ground to the top of your trailer hitch receiver. The next measurement that you will need is the coupler height of your trailer. With your trailer level, measure from the ground to the bottom of your trailers coupler. If the hitch height is greater than...

  • Installing a Trailer Brake Controller on a 2007 Chevy Avalanche
  • Actually the CHMSL circuit is a dedicated brake light circuit that can be used for the stoplight circuit (red wire) of a brake controller. In some cases it can be an orange or a blue wire. What you can do is check the wire you found with a circuit tester like part # 3808 for voltage only when the brakes are applied and none when released. Regardless of what the wire is labeled if the circuit has voltage only when the brakes are applied it would work well.

  • Accurate Picture Of 12" x 2" Hydraulic Trailer Brake Shoe and Lining (One Wheel) # BP04-160
  • I went out to our warehouse and took a picture for you of the brake shoes. The 12" x 2" Hydraulic Trailer Brake Shoe and Lining (One Wheel) # BP04-160 look like the attached picture. They have the same internal bracket you see but have 2 additional holes leaving the other holes in the locations that you referenced.

  • How Does Tekonsha P3 Brake Controller Connect to 2008 Chevy Avalanche
  • On your 2008 Chevy Avalanche no plug is present under the dash to install the Prodigy P3 part # 90195, but the needed wires are already run. You will connect the brake controller wiring with the vehicle wiring already present under the dash. I attached an install video showing a similar Tekonsha brake controller being installed in a Chevy Avalanche that is the same generation as yours.

  • How Does Tekonsha Brake Controller Install in 2008 Chevy Avalanche
  • Your Voyager part # 39510 can easily be installed in your 2008 Chevy Avalanche. However, there is no plug present the dash so you wouldn't need anything more than what you already have. If you check out the install video you can see how a similar controller is wired to a similar 2005 Chevy Avalanche. Basically you just have to wire the 4 wires present under your dash to the 4 wires of the controller and you are done.
