Expert Answers about Hummer


  • Tandem Axle Boat Trailer Tire Wear on Inside of Tire
  • Tire "scrubbing" like what you described does not typically only wear out the insides of a trailer tire. When trailer tires are worn more on the insides then anywhere else that indicates typically that the axle is being overloaded. Axles have a natural arch in them that arches up so that when they are under a load they are horizontal and you get even wear on your tires. Overloading your axle would mean that it is arching towards the ground some and would cause that inside wear. I recommend...

  • Base Plate for 2008 Hummer H2 to Flat Tow with Roadmaster Nighthawk
  • The Nighthawk tow bar part # RM-676 and the Invisibrake kit part # RM-8700 can be used to flat tow your 2008 Hummer H2 but you will need a new base plate kit which for that you'd want the part # 2506-3 and you'd be set.

  • Transmission Cooler Recommendation for a 2008 Hummer H3
  • I have a solution for you, but since we do not have a pan cooler confirmed to fit your 2008 Hummer H3 and you really don't want to hurt ground clearance your best bet would be to install an additional transmission cooler. Depending on how much more cooling you need the part # D13503 could work well for you. For most vehicles just one cooler like this provided enough cooling, since you already have a remote fan cooler this should be more than enough when used in combination.

  • How Does Brake Controller and 12 Volt Accessory Circuit Activate 2008 Hummer H2
  • Under the dash there is a brake controller install wiring bundle you can use to install a brake controller like the Brake EVN # TK63VR. This wiring ties into the 7-way at the rear of your vehicle that you mentioned. There is also a wire under the hood that is red and black near the brake booster that needs to connect to the fuse box/relay box to activate it. It has a ring terminal on it and it attaches to the larger terminal on the front of the relay box. You'll need to install a 30 amp...

  • 7-Way and Brake Controller Recommendation for 2008 Hummer H3
  • What you are looking for is the 7-blade style of trailer connector which is what is in the picture you submitted. You will need to start with a 4-way (if you do not have one). For that you would want the # 18252. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire...

  • Are the Husky Liners Mud Flaps for 2008 Hummer H2 Square or Round at the Bottom
  • The Husky Liners mud flaps for your 2008 Hummer H2 part # HL57361 are square at the bottom like what the majority of the pictures show. The one picture that shows a flap installed on a vehicle is a typical photo and does not indicate the shape of them at all. For a matching front pair you would want the part # HL56361.

  • Recommendation for Large Roof Top Mount Cargo Baskets for a 2007 Hummer H3
  • If your 2007 Hummer H3 has a factory roof rack with cross bars that run side to side, there are a few baskets rated to fit. First is the Yakima LoadWarrior Roof Rack Cargo Carrier, # Y07070. The overall dimensions are 44 inches long x 39 inches wide x 6-1/2 inches tall. I have included a link to the installation details below. Second is the Thule Canyon XT with extension, # TH859XT-8591XT. This is a larger basket at 69 x 40 x 6 inches. If your Hummer has no rack but tracks that run front...

  • Can Either Pin Hole of B&W Tow and Stow Ball Mount part # BWTS10049B be Used
  • Either hitch pin hole of the B&W Tow and Stow Ball Mount part # BWTS10049B can be used in the hitch of your vehicle. Whichever one works for your towing application best will be perfectly fine.

  • Brake Controller Recommendation for 2008 Hummer H3
  • We have what you are looking for, but wiring and brake controller is not included with the Draw Tite hitch part # 75382 which is a fit for your 2008 Hummer H3. Your vehicle already has a 7-way at the rear and has wiring under the dash for installing a brake controller. You should see a bundle that contains a red wire with a black stripe, a white wire, light blue wire with a white stripe, a dark blue wire and possibly an orange wire. The bundle could be above the emergency foot brake,...

  • Recommendation for a Platform Trailer Hitch Mount Bike Rack to Clear the Spare Tire on a Hummer H3
  • Since you have 10 inches between the center of the hitch pin hole and the rear side of the spare tire on your Hummer H3, the Thule Doubletrack Pro XT Bike Carrier, # TH92BJ, is not a good choice. The Yakima HoldUp 2 Bike Hitch Mounted Folding Rack, # Y02443, measures 12 inches from the center of the hitch pin hole to the first bike tray, but 7 inches when folded. This rack will clear the spare tire but only in the towing position. I have included a link to the installation details and...

  • Spare Tire Bike Rack Recommendation for a 2008 Hummber H3
  • Most likely the Hollywood Racks Spare Tire bike rack # HRSR2 that you referenced would fit your 2008 Hummer H3's spare tire. But since it's only been tested on a few vehicles at this point I can't confirm it as a fit yet. For a very similar bike rack that has been confirmed as a fit for your vehicle check out the Thule Spare Me part # TH963PRO. If you plan on carrying any womens or alternative framed bikes without horizontal top tubes you may also be interested in purchasing a Swagman...

  • Converting an M105A Military Trailer Air Over Hydraulic to Electric Over Hydraulic Drum Brakes
  • I have the perfect solution for you! The first thing you need to do is swap out your actuator and for that I recommend using the USA made HydraStar Electric Over Hydraulic Actuator for Drum Brakes # HBA-12 because this company makes very reliable equipment and they receive great reviews from our customers. From my information military trailers like your M105A use larger 1/4" brake lines so you should also need the Fitting # HS43-9035 to make this actuator compatible with your trailer brake...

  • Roof Mount Cargo Bag Recommendation for a Hummer H3 without a Roof Rack
  • I recommend going with a different bag that you can use with the hooks on your Hummer H3. Rightline cargo bag # RL100S30 should be a good option for you. It will attach to a vehicle with or without a roof rack, and in the event that the hooks aren't going to work, which is unlikely, then you could use car clips # RL100600 to secure it to the roof. The clips fit in the gap between the roof and top of the door. I also recommend using protective pad # RL100650 to not only protect the Hummer...

  • Roof Rack Recommendation for 2009 Hummer H2
  • For a 2009 Hummer H2 we have the Yakima Roof Rack part numbers # Y00409, # Y53TR, # Y03536, and # Y00224 which is a confirmed fit and will work well. We don't have anything for a 2011 model as there wasn't a 2011 model made in the US nor do we have anything that was made by Hummer.

  • Recommended Ladder Rack for 2005 Hummer H2 SUT for Rooftop Tent
  • The Reese Towpower TransRACK Workmate Truck Bed Ladder Rack - 800 lbs # RP7063500 will not be compatible with your 2005 Hummer H2 SUT. There isn't a confirmed fit from any of our manufacturers so you will likely need to have something customized. The closest option that may be compatible is the Yakima Overhaul HD Adjustable Truck Bed Rack - Aluminum - 500 lbs # Y01151 which is height adjustable to also utilize the roof rack rear crossbar and has a base that is more easily mounted. Then...

  • Recommended Replacement 4.80/4.00-8 Boat Trailer Tires
  • Generally speaking, a radial tire is going to have a few improved differences when compared to a bias tire like what you currently have on your trailer. A radial tire will flex more than a bias tire, giving it better ground contact, traction and stability. They will also run a bit cooler, especially when the tire is under a heavy load. One advantage a bias tire does have over a radial is a stiffer sidewall, a feature that is useful for off road applications. The 4.80/4.00-8 trailer tires...

  • We have exactly what you need to lock the ball mount platform to the shank of your Curt Multi-Ball Adjustable Ball Mount part # D900 and to lock the shank to your hitch. What you would need is the Trailer Hitch Receiver Lock # e98881. You will need to order a quantity of 3 of these locks and select the keyed alike option before you hit the add to cart button and we will send you out 3 of these locks that will all use the same key. The part # LPL55CB would also be a great license plate...

  • Second Vehicle Kit Recommendation for Brakemaster Braking on Hummer H3
  • You do need to have the breakaway system of the supplemental braking system active. In most cases this is by law too but it's really just a wise choice overall. So you'd need the second vehicle kit for the BrakeMaster kit part # RM-98160. For lighting/safety cables, locks, and covers for the tow bar we have the Roadmaster Falcon All Terrain kit part # RM-9243-1 which comes with all of that as one part number. The diode kit that comes with this allows you to splice into the taillight wiring...

  • Magnaflow Catback Exhaust System Recommendation for a 2003 Hummer H2
  • Yes, as long as you have a 6.0 liter V8 gas engine in your 2003 Hummer H2 the Magnaflow System part # MF16673 that you referenced would work just fine with your rear air load leveling system.
