The Rivian R1 is the perfect vehicle to tackle the outdoors. It's high ground clearance and individual wheel control enable it to navigate rocky terrain with ease. Even the most capable vehicles and drivers, however, can get hung-up on rocks and logs, which can result serious rocker panel damage or worse. Rock sliders help guard against this off-road hazard to keep your truck protected.

Unsatisfied with current Rivian offerings, a team of early owners and longtime off-roaders assembled to engineer the strongest rock slider on the market that can serve as an R1S running board, yet stand up to even the most punishing abuse. What they arrived at is the latest product from Megawatt™ performance products.

Make no mistake, this product is a rock slider first with the added benefit of serving as a convenient Rivian step. Given the weight of the Rivian R1S, and the potential for extreme forces while off-roading, we felt a purpose-built protection solution be crafted first. Only then could added features like a running board step be added.

The Rivian R1S has a curb weight of almost 7,100 lbs. That is close the weight of a Dodge RAM 3500 MegaCab. As such, we used proven slider methods for vehicles like these to benchmark the Megawatt™ Rivian R1S rock slider. We then adapted this formula to fit the lines and unique architecture of the Rivian. The result is not only a rock solid, highly functional slider, but a side-step that looks great.

Note:

  • This product fits 2025 and newer R1S vehicles only

Construction

Fully enclosed tubing

Fully enclosed tubing

Press broken sheet metal Press broken sheet metal
Sheet metal is often used because it is cheaper to manufacture. Unfortunately, this folded structure relies on just four corner welds to prevent the rail walls from splitting apart on impact.
Mounting Points 

One row inline with the frame and a row of inboard brackets

One row offset from the frame

One row inline with the frame and a row of inboard brackets
One row inline with the frame and a row of inboard brackets
Utilizing a single row of mounting points can enable to slider to flex/roll when the outside edge of the slider is pushed upward. This can lead to body damage.
Main Slider Rail Mounting

Inline with the frame

Cantilevered  outside of the frame

Inline with the frame Inline with the frame Mounting the full length of the rail to the frame provides maximum rigidity. Offsetting these mounts creates additional leverage when the rail is pushed up, which can cause flex and frame damage. 
Main slider rail thickness

Undisclosed Undisclosed Thickness of the main slide rail dictates how much force the rail can withstand without bending
Weld type TIG MIG MIG MIG TIG welding, while more labor intensive, results in cleaner, stronger welds.
Coverage Full wheel-to-wheel Mostly wheel-to-wheel Mostly wheel-to-wheel Mostly wheel-to-wheel Rock sliders that do not cover the full length between the wheels leave this space open to a common area for rock damage
Kickout? Yes No No No In addition to providing more space to step, a kick-out also adds additional outside damage protection and a pivot point for navigating obstacles
Underside cover? No No Yes No While attractive, underside plating actually traps large amounts of debris while only providing marginal protection or aerodynamic improvement.

    • 2" diameter box steel
    • .188" thickness

    Rub rail:

    • 1.75" diamter tube steel
    • .120" thickness

    Mounting brackets:

    • .125" plate

    Weight:

    • Approximately 65 pounds per side

    FINISH

    Each slider is enveloped in flat black via a unique four-stage process.

    1. Each slider and its top plate is coated in primer.
    2. Top plates are welded to the slider
    3. Assembled sliders are powder coated in a high-heat oven
    4. A probe is inserted and run the length of the tube to coat the inside with paint

    We realize this might sound like a lot of work to coat a piece of metal. (It is)! However, this process ensures maximum coverage, which in-turn improves corrosion resistance and longevity.
