Changes to Challenger ST Bodies
Driven by 2020 GM Truck Changes
Wooster, Ohio (Sept 5, 2019) – General Motors has introduced changes on their 2020 Chevy Silverado and GMC Sierra ¾-ton and 1-ton long bed pickup trucks that have a significant impact on truck body manufacturers and truck equipment up-fitters. We have highlighted the modifications Stahl has made to its service body offering in order to address the changes to these new GM trucks. It also explains the impact the Stahl modifications have when spec’ing and ordering service bodies.
The first big change to the 2020 GM trucks is in the cab-to-axle dimension. GM decreased the cab-to-axle dimension on ¾-ton and 1-ton long bed trucks from 56-inches down to 55-inches. This shorter cab-to-axle dimension will require a new “GM-specific” set of fender panels for CST98 service bodies. These new GM fenders have the cutout shifted forward so that the rear tire remains centered within the radius.
As has been the case with Stahl Challenger ST fender panels in the past, they are a bolt-on design and can be switched with minimal effort. So, if you have CST98 bodies in inventory and sell one for a 2020 GMC/Chevy application, the new GM-specific fender panels can be ordered from Stahl and easily installed on your stock body. For future body orders, simply let the Stahl salesperson know that the body being ordered is for a 2020 GMC/Chevy application and the proper fenders will be shipped on the unit from the factory.
Stahl has created the two new kits below to address the fender panel issue on the 2020 GM’s. Both kits come with both a curbside and a streetside panel.
New GM Fender Panel Kits
New GM Mounting Bracket Kit
New GM Adapter Plug
