Chevrolet revealed the 2017 Chevrolet Colorado ZR2 and it came as quite a shock when people found out that the new version pulled 2,000 pounds less. While it offers 5,000 pound tow rate it does offer plenty of off-road upgrades, so you will have to work out whether the compromise is worth it.
The Chevrolet Colorado ZR2 towing rate was cut back due to the design of the chassis having been revised. It comes with a two inch higher lift and the track is three and a half inches higher and this has meant that the towing ratings have slipped.
The regular Colorado is able to deal with the extra weight in the back, but the Chevrolet Colorado ZR2 has more focus on the capabilities for crawling over rocks, rather than what it can tow at the back.
You shouldn’t be too discouraged by this though as after all you won’t be towing 5,000 pounds when going off the road, so does the loss really matter?
