Fans and customers holding order sheets for new Chevy Colorado ZR2 pickups are starting to express concerns about the standard "Off-road rocker protection" to use Chevy's exact description, that Chevy is apparently having its dealers install. We did a little digging to see what is know about that specific component at this time.

 

Our first clue was in a 2016 article in Outside Online written by Wes Siler. Siler looked at the rocker protection and wrote, "Combine that with long wheelbase, and we’re just not looking at the angles necessary for a true rock crawler here. Hit some boulders and those standard rock rails and aluminum skid plates are going to take a beating."

William Francis, a member of the Facebook Colorado ZR2 club (that GM-Trucks.com owner Zane Merva started) looked at an image of the trucks being delivered out of the factory and posted the comment, "Odd, no rock rails? dealer installed maybe?" We enlarged and enhanced the Chevy media image a bit and indeed as you can see above, there is no rocker protection on the trucks leaving the factory.

 

Then there is this video we found of a fan checking out the ZR2 in person. The speculation is the dealer didn't mount them properly:

 

 

What say you GM-Trucks.com faithful? No big deal, or a bit of a disappointment?

We don't have one yet (I sure hope we do though) but those guards are installed at the dealer, just like on Z06 and Grand Sport Corvette's ground effects/aero parts. As for the video, possibly not tightened all the way? Even the GM running boards don't move when installed. It appears to be an auto show truck? as I see a carpet flooring underneath it.

I believe it has been stated in the comments of that video that the rock sliders are indeed mounted incorrectly. If you look closely there is way too much room between the rocker panel and the bar. All the LA test vehicles show a much tighter fit and in fact they are so close to the body some of the LA trucks actually have crushed rockers from significant impacts on the sliders. As to why no sliders on trucks in transit, these, along with the spare tire carrier, are a LPO option and will be installed at the dealer. I just hope my dealer gets it right. My spare tire carrier is not going to be mounted so that I can design a better method to quickly remove/install for the times I need full bed capabilities.

      The Chevrolet Colorado ZR2 has earned Cars.com's Pickup Truck of 2018 Award. The Colorado was joined by the Silverado 3500 HD as a nominee. Mark Williams of Cars.com in his write up of the ZR2’s win said the ZR2 is, “…the most distinctive vehicle that's come along in years.” Williams went on to say that besides its off-road capabilities, Cars.com testers were also impressed with, “…how well it does standard pickup truck work, like hauling 1,200 pounds or more of payload in the bed or towing a 5,000-pound trailer off the bumper." That must be one heck of a bumper! We typically tow using the trailer hitch, but that's just us being silly.  
       
      Paul Edwards, U.S. Vice President, Chevrolet Marketing, commented on the win by the ZR2, saying “…ZR2 builds on the boldness of the Colorado program. Our midsize truck line has defied naysayers by selling more than 300,000 trucks in three years, and ZR2 adds forward-looking technology and innovation to the recipe to reach an entirely new group of off-road enthusiast customers.” By “Naysayers”, Edwards is referring to the knuckleheads at RAM and Ford who have sat out the midsize truck explosion for the past half-decade, missing out on literally millions of vehicle sales as a result of that poor planning.

      Four Wheeler Magazine has chosen the 2018 Chevrolet Colorado as its pick for Four Wheeler Pickup Truck of the Year. The Colorado certainly deserves the win, but given the publication’s rules, it seems like it was snuck in. The group says its picks for Four Wheel truck of the year “…was determined by a weeklong, invitation-only competition open to all-new or significantly revised pickup trucks for the upcoming model year.” The Colorado ZR2 is was introduced in 2017 as a 2017 model year truck and is not scheduled to receive any major (or minor) changes in 2018. Hmm. We reached out to Four Wheeler Editor, Sean Holman, who was glad to help explain. Sean tells us that the 2017 Colorado missed the cutoff for the last POTY award due to its late introduction and therefore eligible. Automakers' crazy model and calendar year combos are the reason. Last year, the Raptor won.  
       
      Four Wheeler Editor Ken Brubaker commented on the ZR2’s win, saying, “The ZR2 takes the capable Colorado platform to a new level with a dizzying array of modifications including front and rear electric differential lockers, Multimatic Dynamic Suspensions Spool Valve shocks, a 2-inch-taller ride height, 3.5-inch-wider track width, additional skidplating, 31-inch tires, and many more off-road-centric goodies. The result is a truck that is willing and able to conquer terrain that would leave most other trucks behind.”
       
      The ZR2 was pitted against just two other trucks for the title this year, the Ram 1500 Harvest Edition, Ram 3500 Cummins turbodiesel. Read the full story at Four Wheeler.

       A new recall for the Chevrolet ZR2 has surfaced in owners' clubs and groups. The recall, GM 17345, is related to a failure of the front shock. Those who follow this new off-road truck may recall that GM opted to use a new-style shock developed by an F-1 racing supplier. The recall notices posted say the failure is, "...may have a leaking front shock absorber. noise as a result of contact between the upper control arm and service stop, as well as a potential fractured shock absorber piston rod." Owners are reporting that the inspection is related to manufacture date and that not all ZR2 trucks have the defect that leads to the failure. 

      If you are an owner of a ZR2 and have not received the recall notice by mail yet, you can check to see if your truck is affected at this GM recall lookup site.

      Chevy has shown two hot Colorado ZR2 concepts at this year's SEMA show in Las Vegas. The first is the AEV Concept shown at the top of page. The AEV starts off with a new suspension setup including high-angle ball joints and increased stiffness high-angle tie rods. The truck also adds front and rear jounce shocks and a long-travel rear leaf-spring suspension. The differential gets a cover as part of the full underbody protection kit.
       
      The ZR2 AEV also gets custom wheels and tires, a winch kit, recovery hooks, and rocks a snorkel. In back, Chevy added a refrigerator cooler and there is an air pump and more substantial jack and tire kit. Check out the video for a walk-around on this off-roader.

      Just in time for the annual SEMA aftermarket show in Las Vegas, Chevy has dropped two great-looking special edition Colorados. The ZR2 is already styled differently than other Colorado trims with a more aggressive hood and grille as well as modified front and rear bumpers for added off-road clearance. These two new special editions take the looks up a notch.

      The 2018 Colorado ZR2 Midnight Edition is painted all-black,  and also has black Chevy bowtie emblems and custom 17-inch five-spoke black wheels - including the spare. There is also a black sport bar with off-road LED lighting and sport-bar sail panels, which bring back the Avalanche look in a way.

      The ZR2 Dusk Edition offers the same features as the ZR2 Midnight, but isn’t black. It can be purchased in any other ZR2 exterior finish, but the black accents remain. The ZR2 Dusk Edition show in our images is Summit White with the available 2.8L Duramax turbo-diesel and the diesel-exclusive Performance Cold Air Intake.

      “The Colorado ZR2 Midnight and Dusk Edition models offer customers even more personalization choices from the only company with three distinct trucks: midsize, full-size and full-size heavy-duty,” said Jim Campbell, U.S. vice president, Truck Strategy, Performance Vehicles and Motorsports. “Chevrolet offers more choices because the truck market is too diverse for a ‘one size fits most’ strategy.” Chevy has not said when the new trucks will be available, but we suspect late Fall.
