Team 1EV has engineered an innovative precision fit bolt-on running board with optional rock slider for the Rivian R1T and R1S. With a strong emphasis on balancing proper design language, function, fitment, and quality for the Rivian application, 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. Our goal was to make the boards look like they came from the factory. True to this goal, we didn't add any giant brand logos or out-of-style design features. The moderate face design looks right at home on the Rivian and provides sufficient grip. The boards are tucked in properly, meshing visually with the natural truck lines, and the optional rock slide armor integrates properly and DIRECTLY with the actual Rivian frame structure rail on the top side and running board on the outside edge with proper heavy-duty triangulations to the board.
The R1T weighs almost 7200lbs, and has a GVWR of just over 8,500 - we have engineered to this spec! Our slider is positioned properly, directly under the Rivian frame rail, NOT cantilevered out with brackets - go slide over all the rocks you like, we're ready for you! Team 1EV sliders are functional, not just for looks. Attention to detail is paramount!
Protect the High-Center Damage Prone Mid-Section
Our fitment is bolt-on, by design. We don't like cutting, drilling, or modifying the base vehicle frame structure. We also thought forward on jack points and we've got you covered, with additional jack functionality added.
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 welded frame bracketry and steel plate step surface plates. We finish all surfaces with a rugged textured black powder coating. Running boards are rated for 500lb load. Sliders are engineered for full confidence, starting with heavy wall 2" square tubing bolstered by several direct frame attachment points and triangulations.
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.

Tread Plate Options:
The tread plate on RMaxx Running Boards & Rock Sliders is a bolt-on plate. The plate can be removed and replaced, if desired. Select the tread plate design of your choice when ordering. Replacement tread plates will be available for purchase as well.
First, we highly recommend watching our detailed installation video, which will walk through each step in detail:
The installation is DIY friendly and reasonably easy. You’ll need to get on your back to install these (on the floor or on a creeper, either is fine – use the cardboard packaging the parts ship in on the floor to keep yourself clean). The installation process is straightforward. All kits include a TP55 bit and T20 bit. You will need the following tools (not included):
Additional tools required specific to each plastic panel option:
For hole saw clearance holes in panels (recommended and easiest option)
For removing panels and cutting clearance holes in panels then re-using panels
For removing panels (and not re-using panels)
1 – Park the truck on level ground. Put the truck in ‘offroad’ mode (which raises the truck to create the maximum under truck clearance to the ground).
Select Plastic Panel Option:
2a - Retain outer plastic panels (Requires cutting bracket clearance holes in panels). Panels can be cut without removing from the vehicle (recommended easiest option, Skip to "Plastic Panel Clearance Cutting" below and use cutting template - download HERE). Or, panels can be removed from the vehicle for clearance cutting, then re-installed on the vehicle, Skip to "Plastic Panel Removal"below.
2b - Remove underbody outer plastic panels and do not re-use panels. Note, the factory plastic panels do NOT offer any underbody protection. The purpose of the panels is to improve the aerodynamics of the underside of the truck. Leaving the plastic panels off permanently is acceptable and will not risk damage to the truck and the aerodynamic impact will be insignificant, since the running board brackets extend past the panels anyway.
Plastic Panel Removal (optional): Remove the 3 outer plastic covers on the bottom outside edge of the Rivian, on both sides of the Rivian (6 total plastic covers). These covers simply unbolt and pull off the truck. The covers are not part of the RUS protection – these plastic covers are simply thin plastic covers (same covers Rivian advises to remove when jacking directly on the frame). Clearance cutting the panels is described below.
Plastic Panel Clearance Cutting (optional): Watch the DIY how-to video HERE. The modification entails cutting a clearance hole (or slot) for our brackets to pass through. We provide a downloadable cutting template with the kit (cutting template - download HERE - print full size, 1 to 1, do not 'fit to page' when printing. Once printed, compare a measurement on printed template to ruler and confirm template measurement matches ruler), allowing you to easily mark the covers and guide your clearance cutting. The plastic covers are thin and easily cut with a hole saw, snips, razor, or small saw. A total of 8 slots are required, 4 per side.
3 – Inside the 4" clearance hole, remove the TP55 underbody bolt, install Team 1EV running board bracket by re-installing TP55 underbody bolt through bracket. Brackets only fit in the correct orientation with mounting arm with two square holes facing outside vehicle. Repeat eight times. Torque TP55 bolts to 100 ft-lbs. As shown in photo. If you are not using the plastic panels, the TP55 bolts used are (as measured from the front tire back: front bolt (18" from edge of front fender flair), second bolt (48" from edge of front fender flair), third bolt (72" from edge of front fender flair), fourth bolt (83" from edge of front fender flair).
3b - Note - If plastic panels were removed for clearance cutting, clearanced panels must be re-installed now, before installing running boards.
4 – Hold the running board up to the installed brackets with the running board mounting tabs positioned on the rear side of the installed brackets. Install supplied carriage bolts into the front side of installed brackets' square hole, with the bolt extending through the installed bracket hole and running board mounting tab hole. Attach nut on carriage bolt and finger tighten. Repeat for all eight installed brackets.
5 - Adjust running board to desired position relative to truck, sliding the running board in or out (approximately 10mm adjustment). Fully tighten all carriage bolts, 35 ft-lbs. Turn off 'offroad' mode.
