In the US, the Chevrolet Colorado gets a new equipment package preps the one-ton pickup for more off-road duty. Called the ZR2, it packs the Colorado with upgraded suspension parts, along with a unique set of dampers.

Compared to a standard Colorado, the ZR2 features a much wider track and a lifted suspension. The front and rear bumpers have been modified for better off-road clearance. To boost off-road capability, Chevrolet has made front and rear electronic locking differentials standard in the ZR2 package, as well as  Multimatic Dynamic Suspensions Spool Valve or DSSV. Other upgrades made to the Colorado ZR2 are exclusive 17 inch alloy wheels wrapped in taller 31-inch all-terrain tires and additional skid plated to protect the underside of the pickup.

Chevrolet explains DSSV as off-road dampers that allows the Colorado more off-road capability while retaining on-road comfort and performance. These dampers are position-sensitive with the aluminum bodies each housing two spool valves providing both compression and rebound damping optimized for everyday driving. During extreme off-road use, a third, piston-mounted spool valve delivers additional, uniquely tuned, compression damping. The front dampers also employ a separate rebound valve, which comes into play when the suspension approaches full extension.

The Colorado ZR2 can be specified with two engines. First is the 3.6 liter High Feature V6 with direct injection and variable valve timing. It puts out 308 PS and 365 Nm of torque. The other option is the 2.8 liter Duramax diesel with 181 PS and 500 Nm of torque. The Colorado ZR2 is paired with an 8-speed automatic for the V6 model while the diesel ZR2 shifts via a 6-speed automatic.
