Slim Cup Holder Expander for R2 and R1

The OpenSourceEV Parts Slim Stowable Cup Holder Expander V2 for the Rivian R1S, R1T, and R2 is the easiest, most functional way to hold oversized beverages in your vehicle. It adapts the stock 3.2" cupholder to a 3.66" cupholder, fitting common containers such as the Nalgene 32oz and 40oz and the Hydro Flask 32oz and 40oz bottles.

What makes it better than more general products that do the same thing is a Rivian-specific feature: its slimmed-down sides. Because it is thoughtfully shaved down, it stores easily in a door pocket when not in use, in both the front and rear doors. The slim profile also lets two sit side by side in both the front and rear cupholders, and lets bottles seat without deflection.

• Slimmer for storage: Version 2 shaves the sides down further so the R1S and R1T door pockets close more fully when the expander is stored.
• More durable: An overhauled construction model makes V2 stronger than before.
• Lower cost: V2 is less expensive than the previous version.
• Secure hold: Two oversized supports hold bottles secure left to right and front to back, at angles nearing 90 degrees.
• Built from ASA: Constructed from ASA for durability and UV resistance to handle real sun and heat inside your vehicle.

Bottles not included. Priced each.
