Rivian R1S | Cargo, cabin, and generation fitment
Best Rivian R1S Accessories: Cargo, Cabin, and Fitment Guide
Compare R1S accessories for rear cargo protection, cabin organization, front trunk storage, charging, and exterior access. Rear cargo geometry is R1S specific even when cabin products are shared across the R1 family.
R1S rear cargo fitment is not R1T bed fitment
Shared R1 cabin products can fit both vehicles, but the R1S cargo area and the R1T pickup bed are different. Gen 1 and Gen 2 front trunk and front fascia parts also need exact confirmation.
The reviewed listing explicitly names Rivian R1T.
The listing explicitly names both R1T and R1S for the stated years.
Gen 1, Gen 2, 4.5 ft bed, mounting point, or installed hardware matters.

Start with the use case, then verify the exact vehicle and hardware in the listing.
Protect the R1S cargo area
Choose liners shaped for the R1S rear trunk and confirm the model-year range on every contour-cut product.
Protect and organize the cabin
Screen protection, charging, and console storage can fit both R1 vehicles when the listing explicitly names the correct years.
Match front trunk gear to the generation
The reviewed cooler organizer is for 2022-2024 vehicles, while the reviewed frunk mat is for Gen 2 vehicles produced in 2025-2026.
Add exterior access carefully
Running boards and front license mounts depend on brackets, underbody clearance, and front fascia generation.
Compatibility checklist
- 1The listing explicitly names Rivian R1S and the applicable model-year range.
- 2Rear cargo products show the R1S cargo floor, not the R1T pickup bed.
- 3Front trunk and front fascia products state Gen 1 or Gen 2 when geometry matters.
- 4Seat, cargo, roof, and crossbar accessories match the installed hardware and current Rivian load limits.
- 5Installation does not obstruct cameras, sensors, recovery points, airbags, or safety labels.
- 6The seller provides a usable return policy for fitment problems.
Follow Rivian owner guidance for accessory mounting, cargo loads, roof loads, recovery points, cameras, sensors, and electrical connections.
