Three different suspension options were offered on the Colorado and Canyon: The base Z85 suspension offered a comfortable ride quality. The Z/71 Off-Road suspension added a locking rear differential axle (RPO code G80) and heavier-duty shock absorbers for improved performance off-road, also offering an increased ride height for better clearance. The ZQ8 Sport suspension (see below) offered a lower ride height than the standard Z85 suspension, as well as firmer suspension for improved handling. All suspension packages were offered on 4x2 or 4x4 models in all cab configurations, except for the ZQ8 Sport suspension, which was only offered on 4x2 models. A ZQ8 edition is available with a lower and more road-tuned "sport" suspension than the standard Z85 and comes with 17 inch wheels, color-matched bumper and grille, and low profile fender flares. There is also a Xtreme edition of the ZQ8 which has a different front bumper, rear bumper, side skirts, fender flares, grille, headlights, and 18-inch wheels.

For model year 2009, the Colorado was facelifted again and a LH8 V8 was offered, producing and . For the 2010 model year, the GM badges were phased out, although a few 2010 models had the GM logo on the doors. In 2009, both trucks, as with most 2009 GM vehicles (and combined with OnStar), received a Bluetooth hands-free phone system for the first time as optional equipment. The six-disc in-dash CD changer was discontinued as well, leaving the single-disc CD/MP3 player, and a standard A/M-F/M only radio, with two-, four-, or six-speaker audio systems.
