Nerf Step Bar Recommendation for 2018 GMC Sierra 2500 Diesel

Updated 07/22/2019 | Published 07/18/2019

Question:

Will these work on a 2018 GMC STL 2500 HD double cab diesel with the DEF tank? What other running boards or nerf bars with steps do recommend for the above truck?

I checked with Westin and the Westin HDX Nerf Bars with Drop Steps # 56-137152 are a confirmed fit for your 2018 GMC Sierra 2500HD diesel. They have no fit exclusions for models that have the DEF tank as well.

These are a really great option that I would recommend highly for you. They look great, are easy to use when getting in and out of the truck and will last you a long time. The step tread design will provide great traction as well in wet and dry conditions.
