Chevy’s highly anticipated Colorado ZR2 is finally arriving in dealership showrooms. The first shipment of ZR2s took place on Friday, April 28, headed from the Colorado’s assembly plant in Wentzville, Missouri. Sales of pre-ordered trucks begin early May. The Colorado ZR2 combines increased ground clearance, a wider track, and locking differentials with high-tech Spool Valve shock absorbers to overcome high-speed obstacles. The ZR2 is the first-ever application of Spool Valves in anything outside supercars and dedicated racecars.
