Bolt-on side steps and rock sliders made for the Rivian R1T, R1S and R2. A side step, also called a running board, makes it easier to climb in and reach the roof. A rock slider gives you that step plus armor that protects the outer underbody on the trail. Pick your model and type below.
Model
Side steps (also called running boards) give you a step into the cabin and up to the roof. That’s all they do: they add no underbody protection.
Rock sliders give you the same step plus underbody protection: armor plates guard the outer sides of the underbody and give it a high-center surface that slides over rocks and road hazards without damaging the vehicle.
Choose a side step if you mainly want an easier step in and out for kids, passengers and pets, or a boost when you load the roof. Choose a rock slider if you drive rocky trails or over obstacles that could catch the underbody: it gives you the same step plus armor along the outer underbody. The armor is built into the slider, so it can’t be added to a side step later.
Everything here bolts to Rivian’s factory mounting points under the body, with no cutting or drilling of the frame. The plastic aero panels that cover those points are removed, trimmed or replaced, depending on the product, and some listings offer cover plates for a finished look. Each product page explains the options and links its install guide.
Side steps come in aluminum or steel; aluminum is the lightest choice and won’t rust. Rock sliders weigh much more, because the armor plates are part of the structure. Check each product page for materials, weights and load ratings.
Side steps are designed to stay close to the body, to keep drag and any loss of ground clearance small. A rock slider’s armor sits a little below the underbody on purpose, so a rock or curb hits the armor instead of the vehicle. Added weight and drag can cost some range; how much depends on speed and conditions.
These are designed to keep the factory jack points usable; you still lift on jack pucks, as you would without them. Most are designed to fit Rivian Service Center lifts for routine service without removal, but a service center may still ask for removal for some repairs. On the R1T and R1S, they work with Rivian’s Reinforced Underbody Shield, and rock sliders protect the outer edges the shield doesn’t cover.
Each kit bolts on with standard tools and comes with its hardware and instructions, and the R1T & R1S video playlist has step-by-step install videos. Rock sliders are heavy, so plan on a helper. Prefer a pro? Installation is available at EV Sportline in Van Nuys, CA and Atlanta, GA; ask an expert to set it up.
Made for the R1T from the 2021 model year and the R1S from 2022, including the 2025-on Gen 2 trucks and SUVs. R1T and R1S parts are different lengths and don’t swap between them, and some listings have separate 2021–2024 and 2025-on versions, so pick your model and model year on the product page.
Made for the Rivian R2 from the 2026 model year on; parts for the R1T and R1S don’t fit the R2. Check the product page for availability and the current ship date.
A side step, also called a running board, gives you a step into the cabin and up to the roof, and that’s all: it adds no underbody protection. A rock slider gives you the same step plus armor plates that protect the outer sides of the underbody and give it a high-center surface that slides over rocks and road hazards without damaging the vehicle.
They’re all steps along the side of the vehicle. Running board and side step mean the same thing, and nerf bars are a tube-style side step. None of them protect the underbody; that’s what rock sliders are for.
If you drive rocky trails or over obstacles that could high-center the vehicle, rock sliders protect the outer underbody where it’s most exposed. For daily driving, dirt roads and easier entry, a side step does the job and weighs much less.
No. The armor is built into the rock slider, so side steps and rock sliders are separate products, and a side step can’t be upgraded to a slider.
Each R1T & R1S listing comes in an R1T version and an R1S version. They’re different lengths and aren’t interchangeable, so choose your model on the product page. Parts for the R2 are separate listings.
Yes. The R1T and R1S products here fit Gen 1 and the 2025-on Gen 2 vehicles. Some listings have separate 2021–2024 and 2025-on versions, so choose your model year on the product page.
Yes. The R2 side steps here are made for the R2 from the 2026 model year on and don’t fit the R1T or R1S. Check the product page for availability and the current ship date.
Not the frame: everything here bolts to Rivian’s factory mounting points. Depending on the product, the plastic aero panels over those points are removed, trimmed with a template or replaced with cover plates; each product page explains the options.
Yes. These are designed to keep the factory jack points usable; lift on jack pucks as you would without them. Each product page has the jacking details.
Yes, on the R1T and R1S. The shield covers the center of the underbody; rock sliders protect the outer edges it doesn’t cover, and side steps are designed to fit alongside it.
They’re designed to stay close to the body to keep drag low, but added weight and drag can cost some range, depending on speed and conditions. A rock slider’s armor sits a little below the underbody on purpose, so an obstacle hits the armor instead of the vehicle.
Yes. They bolt on with standard tools and come with their hardware and instructions, and our R1T & R1S playlist on YouTube has step-by-step install videos. Rock sliders are heavy, so work with a helper. Installation is also available at EV Sportline in Van Nuys, CA and Atlanta, GA.
Most of these are designed to fit Rivian Service Center lifts for routine service without removal. A service center may still ask for removal for some repairs; check each product page or ask an expert.
No. Under the federal Magnuson-Moss Warranty Act, Rivian can’t deny warranty coverage just because aftermarket parts are installed. To deny a claim, it has to show the part caused the problem.
