Aluminum 17mm Ball Mount Extension Adapter - 360 Rotation for Car

In this review of the Aluminum 17mm Ball Mount Extension Adapter the bottom line is straightforward: this is a solid, practical upgrade for anyone using suction cup, vent, or dashboard phone holders who needs extra reach and rotation. The adapter is built from durable aluminum alloy and includes a double socket arm plus a 17mm double ball adapter, providing dependable stability and 360 degree adjustment that solves awkward viewing angles and limited mounting positions.

Key Features

• Durable alloy construction: The aluminum build provides a noticeably firmer connection than common plastic adapters, reducing wobble and long term wear.
• Dual 360 rotation: Two rotating joints let users fine tune viewing angle and orientation for both portrait and landscape placement.
• Universal 17mm compatibility: Works with any device or mount using a 17mm or 0.67 in ball head, including many car suction cup and Garmin GPS mounts.
• Compact package: The included double socket arm and 2.4 in double ball adapter add extension without excessive bulk, keeping the setup tidy.
• Easy installation: Simple push-fit assembly makes it quick to attach to existing phone holders and swap between vehicles or mounts.

Who It's For

This adapter is a good fit for drivers who already own a car phone holder or GPS mount with a 17mm ball and want more flexibility in positioning the device for clearer sightlines or to avoid dashboard glare. It is useful for rideshare drivers, delivery drivers, and anyone who frequently adjusts their device between portrait and landscape.

It is not intended for users who lack a compatible 17mm ball head or who need a fully integrated phone mount; if your existing mount uses a different ball size or a bespoke connection, you will need a different adapter or a complete replacement mount.

Pros & Cons

Pros

• Sturdy aluminum alloy construction yields a solid feel and reduced flex compared with plastic versions.
• Dual 360 rotation gives wide adjustment range to eliminate blind spots and awkward angles.
• Fits standard 17mm ball heads, making it widely compatible with car and Garmin GPS mounts.

Cons

• Requires an existing 17mm ball head to be useful, so it is not a standalone mount solution.

Frequently Asked Questions

Will this work with my GPS mount?

Is installation difficult?
No, the adapter attaches by fitting the double socket arm to the ball adapter and then to your existing holder for a quick, tool-free setup.

Does it reduce vibration?
