Designed for Perfect Fitment

Designed to fit R1S Vehicles perfectly, measuring 79" long. These running boards ensure no interference with our mud flaps while providing full coverage under all four doors.

Upgrade Your Vehicle with Strong, Lightweight Steel Running Boards

Our running boards are crafted to match the style of your vehicle, ensuring that it maintains its OEM-like appearance. These boards not only enhance the overall look but also provide easy access for you and your family into your Vehicle.

The boards seamlessly blend with the vehicle's natural lines, positioned directly under the frame rail without protruding brackets.

Exceptional Load-Bearing Capacity

Engineered with confidence, RPM RIV Running Boards are rated for a remarkable 550lb (250kg) load. We have utilized heavy-wall 2" square tubing and reinforced the design with multiple direct frame attachment points and triangulations, ensuring rock-solid stability.

Custom Design for Your Convenience

RPM RIV Running Boards are thoughtfully crafted to make entering and exiting your Vehicle effortless. Recognizing the height and accessibility challenges, we have extended the running boards. The high-strength, die-cast aluminum alloy components feature an anodized and PTFE-coated military-spec finish, ensuring resistance against corrosion. With precision stainless steel pivot pins and maintenance-free self-lubricating bushings, these running boards offer exceptional all-weather performance.

Package Includes and Warranty

Each package of RPM RIV Running Boards includes two pieces specifically designed for the R1S model. We include two full sets of hardware to install the running boards level or at an elevated 7-degree mount.

Along with the running boards, bayonet accessories are also included for your convenience. Additionally, our brand-new running boards come with a one-year warranty, showcasing our commitment to quality. If you encounter any issues, contact us at rpmriv@gmail.com, and we will promptly assist you within 24 hours. We also offer a 30-day refund policy for returns to our local US warehouse address.
