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.\u003cspan class=\"read-more-target\"\u003e \u003cspan class=\"headerspam\"\u003e\u003cstrong\u003eGM Duramax Fitments:\u003c\/strong\u003e 2020, 2021, 2022, 2023, 2024, 2025, 2026 GM 6.6L Duramax.\u003c\/span\u003e \u003cspan class=\"headerspam\"\u003e\u003cstrong\u003eSubmodel Fitments:\u003c\/strong\u003e WT, Custom, LT, LTZ, High Country, 1LT, 2LT, Pro, SLE, SLT, AT4, Denali.\u003c\/span\u003e \u003cspan class=\"headerspam\"\u003eSome exceptions apply, please see individual product pages for specific fitments.\u003c\/span\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003clabel for=\"post-1\" class=\"read-more-trigger\"\u003e\u003c\/label\u003e\n\u003c\/div\u003e","products":[{"product_id":"amp-research-75131-01-light-kit-for-amp-steps","title":"AMP Research 75131-01A Light Kit | AMP Steps with New Style Controller | Universal","description":"\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIncludes four ultra-bright white LEDs\u003c\/li\u003e\n\u003cli\u003eLights up PowerStep surface automatically\u003c\/li\u003e\n\u003cli\u003eStays on for five minutes when door’s open\u003c\/li\u003e\n\u003cli\u003eTurns off automatically when door closes\u003c\/li\u003e\n\u003cli\u003eProvides maximum step visibility at night\u003c\/li\u003e\n\u003cli\u003eBuilt for harsh weather and rough conditions\u003c\/li\u003e\n\u003cli\u003eCompatible with AMP’s new style controller\u003c\/li\u003e\n\u003cli\u003eIncludes wiring and mounting hardware\u003c\/li\u003e\n\u003cli\u003eSimple installation with vehicle-specific instructions\u003c\/li\u003e\n\u003cli\u003eDesigned for safety and convenience\u003c\/li\u003e\n\u003cli\u003eBacked by a limited lifetime structural warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eAMP Light Kit for Powered Running Boards\u003c\/h4\u003e\n\u003cp\u003eIf you're running AMP PowerSteps on your truck, this LED Light Kit is a must-have upgrade, especially if you're often jumping in and out after dark.
