Mil-Spec is one of the latest companies looking for success with restored and modified versions of iconic vehicles. Rather than Porsche 911s or ’60s trucks and SUVs, its canvases are Hummer H1s. The customer vehicles are big, brash off-road machines, but that’s not all the company is capable of.

We recently learned that the crew over there built a Hummer H1 meant for racetrack use, and it is amazing. The base vehicle is a four-door convertible pickup truck, and Mil-Spec thoroughly changed the suspension. It has custom coilovers with stiff springs, and the entire suspension geometry has been revised. Overall, it was lowered a stunning seven inches compared with a stock H1.

The H1’s in-board brakes now feature six-piston brake callipers, and the wheels are wrapped in low-profile Pirelli P-Zero tires. Also impressive is the fact that the truck still has a part-time four-wheel-drive system. Under the hood is a 6.6-liter Duramax diesel V8 similar to that in the production models. But this one has been tuned all the way up to 800 horsepower and 1,500 pound-feet of torque. This engine also plays a role in this truck’s origins. Apparently, the truck was used for final powertrain testing and development. But it was also built to highlight the company’s capabilities. If you want one of these, well, you can’t have one. At least not yet.

For now, Mil-Spec have no plans for offering track-oriented H1s. That’s understandable since the company is still working through building and selling its initial run of 12 off-road-ready vehicles. He did say the truck has generated a lot of interest, though. So, maybe when the company has time, and if a really wealthy buyer really wanted one, maybe the Mil-Spec could work something out. But at least in the meantime, the company is sticking to tall, chunky-tired H1s.
