HUMMER's presence at this year's SEMA show will be typified by a trio of tuned H3s, ranging from a mildly modded Alpha to an H3T ready to traverse the desert surrounding Sin City.

The most sedate of the three is the warmed-over H3 X Alpha concept, which features new 18-inch wheels shod in 35-inch all-terrain tires, black chrome trim, body-colored bumper extensions and clear turn signal housings. The exterior is coated in Canyon Metallic, while inside, the leather seats, armrests and shift knob all receive contrasting orange stitching along with matching piping and a HUMMER Accessories DVD headrest system.

Far more impressive is the H3T Weekend Warrior concept (above), which capitalizes on HUMMER's off-road cred with a series of engine and suspension mods. Output of the 5.3-liter V8 has been increased by around 70 hp through the use of an LS2 cylinder head, high-lift cam and custom 3.5-inch exhaust. Rolling stock is comprised of HUMMER Accessories' 20-inch wheels wrapped in BFGoodrich Baja T/A rubber, suspended by a Light Racing Jounce Shocks and Rod Hall Racing piggyback performance reservoirs, with brakes provided by DBA.

Finally, Four Wheeler magazine got its own H3 Alpha to play with, and began by "de-glossing" the Victory Red paint scheme with a PPG flattening agent mixed with clear to give it an incredibly cool satin appearance. The only engine mod is a MagnaFlow cat-back exhaust, but what Four Wheeler didn't spend on motivation it made up for with suspension components. Nitrogen-charged, two-inch Rod Hall Racing performance shocks and Light Racing Jounce Shocks compliment the flat-black 16-inch Simulock wheels coated in BFG Mud-Terrain T/A tires.
