Quick Answer

Use the Ball Top Cap Adaptor Truck Kits to mount your iPhone 17 Pro in a vehicle by combining the adaptors with 1" or 20mm socket arms. No tools are needed, and the familiar ball design makes installation quick with your existing setup.

Why Use a Ball Top Cap Adaptor for Your iPhone 17 Pro

If you already have a ball-mount system in your truck or 4x4, adding a Ball Top Cap Adaptor is the simplest way to make it work with your iPhone 17 Pro. The adaptor fits directly onto standard 1" or 20mm socket arms, so you don't need to replace your entire mount.

The main trade-off is that you need a compatible socket arm already installed. If your vehicle doesn't have one, you'll need to add that first. But for anyone with an existing ball-mount setup, this is a fast, tool-free upgrade.

What You Get in the Ball Top Cap Adaptor Truck Kits

The kit includes two Ball Top Cap Adaptors that attach to your socket arms. Once installed, you can twist and lock your Quad Lock case or use the MAG Heads for magnetic attachment. The minimalist design keeps the mount low-profile inside your cab.

How to Install the Ball Top Cap Adaptor with Your iPhone 17 Pro

  1. Step 1: Attach the Ball Top Cap Adaptor to your socket arm: Slide the adaptor onto your existing 1" or 20mm socket arm. No tools are required—the ball design clicks into place securely. Make sure the socket arm is clean and free of debris before attaching to avoid a loose fit.
  2. Step 2: Secure your iPhone 17 Pro with a Quad Lock case or MAG Head: Place your phone (with a Quad Lock case) onto the adaptor and twist to lock. Alternatively, use the MAG Head for magnetic attachment if you prefer a quicker on/off. Double-check that the twist-lock is fully engaged—partial locks can release over bumps.
  3. Step 3: Adjust the viewing angle and test stability: Position the socket arm to your preferred angle. Give the phone a gentle shake to ensure the mount holds firmly before driving. If the mount feels loose, verify that the adaptor is fully seated on the ball—partial insertion is a common mistake.
