Sooner than later, the aftermarket market will no longer be exactly that. Following a positive reception of the H3 Street Concept at the 2005 SEMA show, General Motors will unleash the H3x in 2007. The extra x in the name is designed to attract the customization crowd as it includes chrome tube-steps, exterior trim and fuel door. Other exterior enhancements include unique tires and wheels, a body-colour grille and spare tire cover.The H3x will feature the same powertrain as the regular H3. The truck will arrive in dealerships late in the upcoming summer.
