- Parts Needed to Flat-Tow a 2006 H3 Hummer
- If you are looking to flat tow your 2006 Hummer H3 you are going to need several components that we offer, but a front mount hitch is not designed to be flat towed with.
Instead, you will want a base plate kit like our Roadmaster XL Base Plate Kit # 2505-1. This will provide the attachment point for your vehicle so that it can be towed.
Next, you will need a set of tow bars. I recommend the Roadmaster Sterling Tow Bar # RM-576, this tow bar comes with safety cables, lighting wiring and qui

- Can a Transmission Cooler be Used to Bypass the Factory Cooler on a 2007 Hummer H3
- It is usually the other way around with factory transmissions coolers in radiators. By that I mean that normally you see a problem with the factory coolers, not the aftermarket replacements. It is possible to bypass the factory cooler in the radiator by blocking off the input/output locations for the transmission cooler on the radiator.
You would then need to mount the largest possible cooler that you can get to fit or install a remote cooler with its own fan. The Series 9000 Plate-Fin Transm

- Economical Roof Mounted Cargo Carrying Solutions for 2007 Hummer H3
- For a universal roof rack you could use # DTA968. You would need 2 of these bars. You could then mount a basket to them. A better option would be to install heavier-duty crossbars using the following parts:
Yakima 48 inch load bars, part# Y00408
Vehicle Specific Landing Pads, two sets of part # Y00224
Control Towers, part # Y00214

- Both the Rola Platypus Expandable Roof Top Bag, part # 59100 and the Thule Tahoe Roof Mounted Cargo Bag, part # TH867 are quality bags.
Personally I would go with the Thule Tahoe because it can expand offering two additional cubic feet of storage space. Both bags would work well on your 2008 Hummer H3 and would mount to your factory roof rack.
Both bags are water resistant, but are not waterproof. Anything stored in the bags that cannot get wet should be stored in plastic.
