Swigzy Extra Wide Car Cup Holder Expander for Yeti 14oz & 46oz Rambler — Offset, Soft‑Touch Grip

Swigzy's Extra Wide Car Cup Holder Expander adapts most vehicle cup holders to securely hold large tumblers like Yeti 14oz and 46oz Ramblers.

Large insulated bottles and oversized tumblers often wobble or won't fit into shallow stock cup holders. This Swigzy expander increases diameter and offsets the base so bigger mugs sit level and accessible without blocking neighboring holders. The design balances secure grip with easy in-and-out access, built for everyday driving and outdoor adventures.

How does the expander keep tall tumblers stable while driving?

The expander uses a soft-touch rubber top and an adjustable base that compresses to fit your vehicle's original cup holder. That combination grips the bottle, reduces vertical movement, and prevents tipping during turns or over bumps.

• Soft rubber rim cushions and holds bottles without scratching
• Expanding base adjusts from 2.6" to 3.8" diameter for a tight fit
• Offset design reduces interference with adjacent holders

Which bottle sizes and brands will this fit?

Swigzy designed this model specifically for larger tumblers and bottles. It’s sized to accept Yeti 14oz and 46oz Ramblers and accommodates other common large bottles, while a separate universal adapter covers most mid-size drinkware.

• Compatible with Yeti 14oz & 46oz Rambler models
• Works with Hydro Flask 24oz mug and RTIC 36oz bottles
• See Swigzy's universal 18–40oz option for other sizes

Will it work in my car, truck, or boat?

The expanding base and offset mount make this expander suitable for many vehicles and recreational platforms. It fits a wide range of brand cup holders and performs well in cars, SUVs, boats, and off-road vehicles where cup holder shapes vary.

• Expandable diameter fits both narrow and wider factory holders
• Compatible with Tesla, Toyota, Ford, Nissan, Lexus, Chevy, and GMC
• Also compatible with golf carts, UTVs, ATVs, vans, trucks, and RVs

How durable and user-friendly is the Swigzy expander?

Built from premium materials, this cup holder adapter resists wear from repeated use and road vibrations. The soft-touch top makes inserting and removing tumblers effortless, while the construction holds shape under rugged conditions.

• Premium materials for lasting performance
• Soft rim prevents scratching and eases bottle removal
• Offset base allows two adapters to be used side-by-side
