2020-2025 GM 2500HD/3500HD 6.6L L5P Duramax Side Steps

Constantly climbing in and out of your 2020-2025 GM 2500HD/3500HD 6.6L Duramax can certainly pose a challenge, especially if your truck didn’t come with side steps or if you’ve added a lift kit and larger tires. And while factory side steps might work for stock-equipped trucks, they often fall short once you've upgraded your rig. That's exactly where our selection of aftermarket side steps comes to play as they're designed to not only enhance the style of your Sierra or Silverado but also provide easier, more secure cab access. For lifted trucks, we offer options with drop steps to make entry and exit effortless, even with a higher ride height. With a variety of styles and finishes available, you can give your truck a more aggressive look while improving its overall functionality. GM Duramax Fitments: 2020, 2021, 2022, 2023, 2024, 2025 GM 6.6L Duramax. Submodel Fitments: WT, Custom, LT, LTZ, High Country, 1LT, 2LT, Pro, SLE, SLT, AT4, Denali. Some exceptions apply, please see individual product pages for specific fitments.
