The Unexpected Off-Road – Hummer H2 SUT With a Lift & 37 Inch Tires

If someone asked me to put a top 10 list of the most controversial models available on the market of used SUV/Truck vehicles, then chances are high that Hummer H2 would make it to this list. The reason for that may be found in the design itself, which you either enjoy or despise, and that strong mall-crawler aura created by countless hip-hop and R&B video clips of the 2000s which makes us completely forget about the true off-road DNA of this vehicle.

The H2 was designed as the civilized version of the rugged and brutal Hummer H1 popularized by Arnold Schwarzenegger and featured a lot of serious 4×4 tech in the stock form to conquer nearly any off-road trail. The H2 was equipped with an independent front torsion bar suspension and rear 5-link coil spring suspension specially created for this model. The factory equipment includes such things as the front hitch receiver for a winch, rock sliders with removable u-steps, full undercarriage skid plates, rear tire carrier, rear differential E-locker, and absolutely huge wheels.Hummer H2 SUT Offroading

SUT is the pick-up version of the H2, which stands for Sport Utility truck and it definitely has that genuine Hummer 4-door hard-top vibe familiar by the H1 models. No wonder that GM picked this body style to resurrect this nameplate in the form of an EV and make a loud statement to the world.

“Some of the biggest disadvantages of this model that make it a less common choice among off-road enthusiasts are the weight of nearly 6,500lbs and the fuel efficiency of the thirsty 6.0L engine. But none of the above-mentioned facts could stop the real fan of these vehicles from taking them off-road, especially after trying them at the Am General proving grounds!”

How did you become interested in off-roading?

– My dad always had some kind of truck or dune buggie that I rode around when I was a kid, it started from there for me.
Then in 2002 had the opportunity to work for Hummer of Orlando as a service technician. As a Hummer service technician, you had to be trained on the operation of H1’s. So in 2003, I was sent to Am General Off-Road and Technical training academy. This was my first experience driving anything off-road, to drive an H1 at their proving grounds was an amazing experience I’ll never forget, also got sent back for the same style training in 2008. This is where I got my interest in off-road trucks and have never looked back since.

Why did you choose this particular model for your project?

– After working for Hummer for 9 yrs I never had the opportunity to buy a Hummer. So when the opportunity was right I bought my dream truck in 2012 a 2005 Hummer H2 SUT desert sand. This was my dream truck because way back in 2003 when I was at AM Gerneral training I caught a glimpse of an H2 SUT before anyone had seen one and I told my self if they come out with this truck this is the one I want!

What inspired you to choose this modification style?

What inspired me to choose this particular truck was how the SUT resembles an H1 4 Door hard top.

What challenges did you face while putting it together?

After working at the Hummer dealership for so many years this truck was easy for me to work on.

What do you love about your vehicle?

I love how all the windows roll down including the back window makes for a great open-air experience. Also, I love how different it is. In the off-road world there are very few H2’s taken off-road to the extent I do. Most often I get the comments out on the trail how did you make it here with that truck or people are just in shock to see it out on the trail. That’s why I named my YouTube channel The Unexpected Off Road taking my H2 places people don’t expect me to go.

Is it your daily or a weekend ride?

– This is my daily ride I love this truck too much to leave it parked.

Do you take it off-road? If so, where and how often?

I’m out almost every weekend in my truck, off-road trails are 15 mins from my house
