Best Rivian R1T & R1S Accessories 2026: Top Upgrades & Must-Haves

Rivian's R1T truck and R1S SUV are adventure vehicles at heart, and the right accessories make them even better. Rivian's official accessory shop is well-stocked, and the aftermarket is growing. Here are the best accessories for Rivian owners in 2026.

Essential Accessories

1. Gear Tunnel Crossbars and Bag — [Rivian Gear Tunnel Shuttle](#affiliate) (~$350)

The gear tunnel is the R1T's most unique feature — a pass-through storage compartment between the cab and bed. The official Rivian Gear Tunnel Shuttle is a wheeled bag that slides through the tunnel and holds 60L of gear.

Paired with the Gear Tunnel Crossbars (~$200), you can mount a table, bike rack, or gear platform that extends from the tunnel. This is the accessory that makes R1T ownership special.

Pros:

Unique, innovative storage solution
60L capacity
Wheeled for easy loading
Weather-resistant material

Cons:

Only for R1T (R1S does not have a gear tunnel)
Expensive for a storage bag
Takes some practice to load efficiently

2. All-Weather Floor Mats — [3D MAXpider Kagu for Rivian](#affiliate) (~$220)

The Rivian interior is premium, and protecting it from mud and adventure debris is essential. The 3D MAXpider Kagu mats fit the R1T and R1S perfectly with deep channels that contain significant liquid volume.

The official Rivian Floor Mats (~$175) are good but have shallower channels.

3. Roof Crossbars — [Rivian Roof Crossbars](#affiliate) (~$450)

Essential for mounting bike racks, ski carriers, or cargo boxes. The official Rivian crossbars mount to the factory roof rail tracks and support standard T-slot accessories.

Weight limit: 150 lbs dynamic (while driving), 600 lbs static (parked, like a rooftop tent).

4. Tonneau Cover — [Rivian Powered Tonneau Cover](#affiliate) (~$2,000)

The powered tonneau cover (R1T only) opens and closes at the touch of a button and protects your truck bed contents from weather and theft. It is expensive but genuinely useful for daily-driving truck owners.

5. Camp Kitchen — [Rivian Camp Kitchen](#affiliate) (~$5,000)

The most ambitious Rivian accessory. A pull-out kitchen that slides from the gear tunnel with a two-burner induction cooktop, sink, prep area, and storage. Powered by the R1T's battery. Expensive but incredible for overlanding.

Aftermarket Picks

Screen Protector — [Abstract Ocean Rivian Screen Protector](#affiliate) (~$35)

Matte anti-glare protector for the Rivian's 15.6-inch center touchscreen. Reduces fingerprints and glare significantly.

Seat Covers — [Covercraft SeatSaver for Rivian](#affiliate) (~$150)

If you use your R1T or R1S for outdoor adventures, seat covers protect the vegan leather from mud, dog hair, and gear wear.

Charging Accessories — [Rivian Wall Charger](#affiliate) (~$500)

Rivian's official 48A wall charger with a clean design that matches the vehicle aesthetic. Works with any EV via J1772 connector.

FAQ

Are Rivian accessories overpriced? Some are (the camp kitchen at $5,000 is extreme). But the floor mats and gear tunnel accessories are reasonably priced for the quality. Aftermarket alternatives exist for basic accessories at lower prices.

Do Rivian accessories void the warranty? Official Rivian accessories do not. Aftermarket accessories that are non-invasive (mats, protectors, organizers) do not affect warranty. Modifications to electrical or structural systems could.

Can I use Tesla accessories on a Rivian? No. The vehicles have completely different interior dimensions, screen sizes, and mounting systems. Always buy Rivian-specific accessories.

Where can I buy Rivian accessories? The Rivian Shop (online and in-vehicle) has the official lineup. Amazon and specialized EV accessory retailers carry aftermarket options.
