Integral Ultimate Expander Car Cup Holder – Adjustable Base & Universal Fit (3.4–4.0 in)

Why the Integral Ultimate Expander helps you stay organized on the road

The Integral Ultimate Expander Car Cup Holder reimagines how you manage drinkware in your vehicle. With a flexible, secure base and thoughtful design, it accommodates your water bottle, thermos, or mug with a snug, confidence-inspiring hold. Whether you reach for a 32-ounce Hydro Flask or a compact coffee mug, this expander adapts so drinks stay within easy reach while you focus on the drive.

How it adapts to your vehicle

Installation into a standard cup holder takes seconds. The expander uses a 3-ring adjustable base that ranges from 2.5 to 3.75 inches in diameter. The offset base keeps the adjacent cup holder open, so you can still grab another drink or stash small items nearby. For vehicles with recessed or covered holders, two included spacers can add up to 2 inches of height, ensuring a snug, secure fit in a wide range of models from compact sedans to SUVs.

Stays firmly in place

The secret lies in built-in silicon grips that bite into the cup holder and hold steadier as temperatures rise or roads get rough. This design helps keep an oversized bottle or mug upright and reduces movement during sharp turns or bumpy surfaces.

Every drinkware fits

The expander includes an integrated mug handle slot so your favorite mug slides in with ease. It accommodates 14oz YETI Rambler, 24oz Rambler, most standard mugs, and many other tall bottles.

Simple, universal installation

Two easy steps and no tools are all you need. Hold the base, twist the top, and let the base retract or expand to your cup holder. The result is a universal fit that adapts to many vehicles and cup holders.

What you gain in real life

In everyday commutes, road trips, or family adventures, having a stable, reachable drink space can bring a quiet sense of organization. The adjustable base and height spacers expand your options without sacrificing the rest of your console or cup holder.
