      Proudly Made in the USA 🇺🇸

      Team 1EV has engineered the most innovative and precision fitment bolt-on running boards and rock sliders for the Rivian R1T and R1S.  With a strong emphasis on balancing proper design language, function, fitment and quality, the RMaxx Running Boards & Rock Sliders bring the convenience of a running board together with the optional protection of a properly engineered armored slider in a design that fits right and looks fantastic on the Rivian R1T and R1S.   Attention to detail is paramount and our goal was to make the steps look like they came from the factory.  True to this goal, we didn't add any logos or out-of-style design features.  The modest tread design looks right at home on the Rivian while providing sufficient step traction.  The boards are tucked in properly, meshing visually with the natural truck lines, and the rock slider armor skid plate integrates properly and DIRECTLY with the actual Rivian frame structure rail on the top side (NOT cantilevered out with brackets) - go bang and slide over all the rocks you like, we're ready for you!  Team 1EV rock sliders are functional, not just for looks.  

       

      Material specifications are equally suited for the street, overlanding or Moab, take your pick, you're covered.   Running boards start with CNC-bent 1.75" OD alloy steel tubing with laser cut and welded frame bracketry and steel tread plate step surfaces.   We finish all surfaces with a rugged textured black powder coating.   Running boards are rated for 1000lbs load.  Sliders are rated for 1760lbs+ loads, consider them simply indestructible!

        

      We offer two main options, Running Boards or Rock Sliders.  

      • What is the difference between Running Boards and Rock Sliders?Listen up, there is a lot of confusion / mislabeling by competitors using the terms interchangeably, do not be fooled or mistaken!  Truth is, Running Boards are simply side steps -- that is all; these do not protect the underside of your Rivian.   Rock Sliders, are an entirely different product featuring a full structural frame member which has been carefully fortified to support extreme loads and 'rock sliding' on the integrated underbody armor skids plates, while also providing a side step function on topside tread plate steps.  Learn more HERE.
      • Which is right for you, Running Boards or Rock Sliders?  In both cases, you'll get the convenience of side steps.   If you want to add underbody protection to your Rivian (for road hazard protection, for safe off-road & overlanding usage, or to simply safeguard the outer battery / underbody) the Rock Slider is best. 

       

      Running Boards and Rock Sliders bolt-on directly to the Rivian frame.  To access the frame, the factory plastic covers must be removed.  Several options exist:

       

      For Running Boards:

      1. Remove the plastic covers and leave them off (cheap and easy)
      2. Cut bracket clearance holes (4") through the plastic covers and leave the covers on.  Requires ordering the add-on hole saw and cutting holes using our templates (low cost option to keep factory plastic covers installed, but does require cutting) - preview instructions HERE.
      3. Remove the factory plastic covers and replace with our bolt-on aluminum aero plate covers, which feature proper clearance holes for brackets, and proper access ports for jack pucks (Recommended option).

       

      For Rock Sliders:

      1. The factory plastic covers are removed and replaced with full coverage steel armor skid plates.  No cutting or drilling required.

      • Does Rivian's RUS provide the same protection as Rock Sliders?  No.  The Rivian RUS protects the center underside of the Rivian -- RUS stops about 12" inboard from the edge of the Rivian, providing no protection to the 12" outer edges of the floor.  Our RMaxx Rock Sliders fully protect the outer 12" sections and work perfectly with Rivian's RUS (fully compatible and complimentary.
      • Do These Impact Range? No, not really. Our Running Boards and Rock Sliders were very carefully designed for minimal aero impact - our design is highly aerodynamic and stays “inside” the outer tire aero surface.  Our brackets do not hang down like other inferior products and we give up almost zero ground clearance.  Rest assured, we've done everything to minimize range impact. 
      • How Much Load Will They Support? RMaxx Running Boards are rated for+1000lbs loads. And RMaxx Rock Sliders feature extensive frame fastener points and extra gusseted structure weldments for the ultimate strength - RMaxx Rock Sliders are rated for 1760lb+ loads! Yes, you could place 100% of the Rivian Rated Load on your slider, and the slider won't flinch!
      • Will I Lose Ground Clearance?  RMaxx Running Boards feature low-profile brackets and give up zero ground clearance!  The RMaxx Rock Slider skid plate is positioned about one inch lower than the Rivian underside belly. This provides a 1" gap when traveling over obstacles or hazards you want to impact the skid plates (safe) - not the Rivian underside (not safe)!
      • Can I Install At Home? Yes, installation is straight forward, bolt-on design and DIY friendly.  No extra parts or specialty tools are required.   No permanent modifications to the truck frame structure are required.   Parts are heavy, so having a helper is recommended.
      • Are Jack Points Still Accessible?Running Board brackets are clearanced for all Jack Pucks and to allow Rivian Service to lift the vehicle without issue.  Rock Sliders bolt-on over the frame jack points and those jack points are translated to the slider skid plate in similar locations.  These jack points are approved for use with Jack Pucks or by 4-post lifts. Rivian can be jacked from the Slider center point on the vehicle side center, effectively lifting the entire side of the Rivian with one jack.
