The 2021 GMC Sierra 1500 and Sierra HD offer all the right components and equipment to get the job done, but unfortunately, the availability of one of the nameplate’s more popular packages was just reduced, with the GMC Sierra ProGrade Trailering System no longer available to order on certain trim levels.
More specifically, the ProGrade Trailering System is no longer available to order on 2021 GMC Sierra 1500 SLE and 1500 Elevation trims. Previously, both trims offered the feature as an available option.
With regard to the heavy-duty lineup, the ProGrade Trailering System is no longer available to order on 2021 GMC Sierra 2500HD SLE and SLT Double Cab trims, nor is it available with the 3500HD SLE trim. The 2500HD SLE and 3500HD SLE previously offered the feature as an available option, while the 2500HD SLT Double Cab previously fitted the feature as standard.
