But, it was no small feat for Multimatic. The company, along with Chevrolet engineers, did not simply slap the same two valve dampers on the truck for off-road purposes. Instead, it reengineered them and added a third valve for off-road supremacy.
According to Motor Authority, deflection discs and shims aren’t present. The spool valves replace them, which consists of a spring, a piston and a sleeve to allow the damping fluid to travel through the shock. Cutouts let the fluid through and the actual shape of said cutouts affect the damping.
Taking this blueprint, Multimatic added a third spool valve within the shock body for an off-road compression profile, while the piston here adds an off-road rebound to keep things cool when the going gets rough. Of course, this also helps tremendously with ride and handling quality, and it’s why Chevrolet says the 2017 Colorado ZR2 will be the truck you can off road on Sunday and drive to work on Monday.
We had a chance to ride along in a pre-production Colorado ZR2 through a Chevrolet development course, and from what we can tell, Multimatic has aced it. We can’t wait to spend some time with the 2017 Colorado ZR2 to really put this technology to the test.
