Rivian R1T RMAXX Heavy Duty Gear Tunnel Dual Slide Out Trolley Sled & Storage Chests & Boxes

As Seen on Rivian's Display R1T at Work Truck Week 2025!

Team 1EV set out to create the ultimate gear tunnel storage system—an intelligently designed ecosystem tailored for the R1T gear tunnel. Our RMaxx setup excels on every level. Featuring an easy bolt-in design, no permanent modifications are needed. It’s engineered for convenience, with the ability to pull out from both sides of the truck! Our patent-pending dual-side pull-out design maximizes gear tunnel space and offers heavy-duty load ratings. 

Recognizing that every customer has unique needs, we made modular configurations a priority. With a range of options, we’ve created a system that allows you to order it exactly how you want—offering an impressive 32 different setups! Plus, the sled is designed to be ‘mod-friendly,’ with built-in mounting bosses for bolting or strapping your own gear onto the sled.

By using an extendable sled for storage, you can fully access and utilize the entire gear tunnel volume. With a variety of storage options available, you can customize your setup to fit your specific needs. Choose from three different storage box types—two toolboxes with drawers and an open-top box—or use the sled’s multiple mounting and strapping points to secure your own gear.

Highlight Features

• Better utilize great space in gear tunnel – each component of this system is shaped for maximum storage capacity within the R1T gear tunnel
• Mix and match storage options to suit your needs. Any box option can be mounted to either side of the sled
• One slide comes out either side of vehicle to allow heavier carrying capacity and so that all storage can be accessed in confined areas like a garage or parking lot
• Team 1EV partnered with the manufacturer of leading brand toolboxs to create a professional grade product with a limited lifetime warranty against manufacturing defects
• CNC laser cut and formed alloy steel construction is black texture powder coated for long indoor/outdoor life
• Quick and easy bolt-in (no modifications) installation

Dual Slide Out Trolley

• 250 lb working load capacity on each side (500lbs total)
• Each side is built with three heavy duty roller slides positioned in cross axis for maximum rigidity and load capacity
• Sleds lock into place when fully extended and when stored. A simple single-hand pull handle releases
• A bonus drawer is built into the end of each sled and is perfect for small but frequently used items.  Sled drawer opens even when sled remains locked in gear tunnel - Measures: 5.25" width x 23.25" length x 1.75" depth 
• Assorted hard-mount bolt anchors and strap hook points allow unlimited mounting options for various other gear and accessories
• Designed to work with all Team 1EV Storage Chests and Storage Boxes, or with any third party gear or accessories using integrated module mounting points
• Note: Due to Rivian build variance, it may be necessary to adjust sled clearance to the gear tunnel door.  The factory gear tunnel door hinge placement can cause the gear tunnel door surface (when open) to vary by more than 1 inch.   Minor height variation can be accommodated for by using special brackets available at no cost from EV Sportline. In extreme variance cases, the door must be adjusted down to clear the gear trolley.   Contact EV Sportline if assistance is needed.   

Storage Chests with Folding Work Platforms

• Choose either 3 drawers or 1 drawer toolbox. Each toolbox drawer has 100 lbs rated slides to carry even your heaviest tools and a quick release latch to ensure the drawers stay closed when not in use. Also, each drawer includes a pre-cut drawer liner to give your tools a soft surface to sit on
• The 3 drawer box has shorter drawers, perfect for hand tools, while the 1 drawer box has a single large drawer, perfect for larger power tools or off-roading equipment
• Both toolboxes have an automatic (gas strut) opening tabletop.  Simply release the latch and the tabletop will raise and lock into place to give you plenty of work or prep space. The tabletop also includes rubber bumpers along the edge to ensure protection of the Rivian body panels
