A GMC Sierra phone mount should feel like it belongs on the dash, not like something stuck on as an afterthought. The Sierra has a wide cabin, real dashboard vibration on rough roads, and several very different infotainment layouts depending on the model year and trim. That makes fitment more important here than it is in a typical sedan. This guide covers custom-fit options first, keeps the universal recommendation to one mount, and breaks down which option fits Sierra 1500, 2500HD, and 3500HD interiors by screen size.
GMC Sierra Dashboard Generations and Fitment
The Sierra name covers multiple dashboard designs, and a mount advertised broadly for “the Sierra” may fit one screen configuration and fail completely on another. Before choosing a mount, confirm the truck’s year, light duty or HD body, and infotainment screen size.
- 2014 to 2018 Sierra 1500: Traditional center stack with a smaller integrated screen. Custom mount choices are limited for this generation, so a well placed suction mount is usually the practical answer.
- 2019 to 2021 Sierra 1500: Redesigned dashboard with a 7 or 8 inch display and usable upper dash attachment points. Several solid custom mounts fit this interior.
- 2022 refresh through current Sierra 1500: Many SLE, Elevation, SLT, AT4, AT4X, Denali, and Denali Ultimate trucks use the wide 13.4 inch center display, which needs a mount built specifically around that screen.
- Sierra 2500HD and 3500HD: HD dashboard timing runs on its own schedule. Many 2020 to 2023 HD trucks use the 7 or 8 inch layout, while newer HD trucks have moved to the 13.4 inch layout.

1. RERPRO Magnet Phone Mount for the 13.4 Inch Screen
Best overall for 2022 and newer Sierra trucks with the 13.4 inch display.
The RERPRO mount is built specifically for current generation GMC Sierra 1500, 2500, and 3500 trucks equipped with the 13.4 inch touchscreen. It installs with the truck’s original screws, so it does not depend on glue, a suction cup, or pressure against a vent blade. That gives it a more integrated look than a universal mount.
The six inch slide rail is what separates it from a basic fixed bracket. You can move the phone left or right along the rail and adjust the double ball arm through a wide range of angles. The magnetic head is designed for MagSafe compatible phones and cases, and other phones can use an included metal ring.
The rail can also accept an additional compatible holder, which is useful if you want a second phone or a small camera on the same base. The tradeoff is that the system is larger and more visible than the compact Kaishengyuan bracket below.
2. Kaishengyuan Magnetic Vent Phone Mount for the 13.4 Inch Screen
Best compact custom mount for the refreshed dashboard.
This Kaishengyuan mount is built for Sierra and Silverado trucks with the factory 13.4 inch touchscreen. The metal bracket attaches around the OEM dashboard and vent area, keeping the phone close to the display without taking up windshield space.
The magnetic head rotates 360 degrees and uses a strong internal magnet array to hold compatible phones, which makes one handed attachment easy. The overall footprint is smaller than a rail based system like the RERPRO, so it is a good pick for drivers who want one phone next to the display and nothing extra.
The listing is for the original factory dashboard and is not intended for aftermarket dash modifications. Confirm the 13.4 inch screen before ordering, since a similar looking Kaishengyuan mount is built for the 7 or 8 inch dash instead.
3. Bulletpoint RubiGrid Multi-Device Dash Mount
Best for multiple devices, work trucks, and overland setups.
The Bulletpoint RubiGrid is not a single phone holder. It is an all metal dash platform built to hold several devices at once, including phones, tablets, action cameras, and handheld radios. The slotted base lets you reposition attachment points instead of committing to one fixed spot.
The kit includes Bulletpoint’s 20mm ball system, a carbon fiber and Kevlar blend arm, and a spring loaded phone cradle that rotates 360 degrees. It is the strongest option here for a driver building a real command center, though it is more hardware than most people need for a single phone.
The listing covers 2019 and newer Sierra and Silverado trucks broadly. Because GM changed dashboards and screen layouts several times during that span, compare the product photos with your exact truck before ordering rather than assuming every trim uses the same upper dash mounting area.
4. Kaishengyuan Magnetic Phone Mount for 7 and 8 Inch Displays
Best custom fit for 2019-2021 Sierra 1500 and 2020-2023 Sierra HD.
This Kaishengyuan version is built specifically for Sierra trucks equipped with the factory 7 or 8 inch display. The CNC metal base and padding are shaped for that dashboard, giving it a more secure anchor than a generic vent clip.
The magnetic holder keeps the phone close to the center display and works with a broad range of phones when paired with a magnetic case or the included metal plate. Its short bracket keeps the phone close to the dash, which helps reduce the bouncing that longer suction cup arms tend to produce in a full size truck.
This mount is for the OEM dashboard, not modified vent or screen surrounds, and it does not fit the newer 13.4 inch display, even on Sierra HD trucks whose model years overlap with the earlier dash.
5. MAGIC JOHN Car Phone Holder
Best universal windshield mount.
The MAGIC JOHN Car Phone Holder is the only universal recommendation in this guide. Its suction cup is built for smooth windshield or dashboard surfaces, and the metal bodied cradle holds most phone sizes. It is a practical choice for 2014-2018 Sierra trucks, where custom mount options are more limited.
A 360 degree ball joint supports portrait or landscape positioning, and a one touch release button makes the phone easy to remove. In a Sierra, keep the arm as short as practical: a long arm puts more strain on the suction base and increases phone movement on rough roads. The lower driver side windshield is usually a better spot than the middle of the glass, as long as local windshield obstruction rules allow it and the mount does not block your view.

Common Mounting Problems in the GMC Sierra
Long arms amplify truck vibration
The Sierra’s wide dashboard tempts drivers to reach for a long telescoping arm. That improves reach but also adds strain on the base, and on rough pavement the phone can oscillate even when the suction cup itself stays put. A short custom bracket mounted close to the dash is almost always more stable.
The center vents are not ideal anchors
A light vent clip can work for occasional use, but a large phone, thick case, and charging cable put repeated stress on the vent assembly. Vent placement also exposes the phone to hot air in winter and blocks airflow in summer, which is why no vent clip made the primary list here.
The 13.4 inch screen changes everything
The refreshed display takes up much of the center dash. A mount built for the earlier 7 or 8 inch screen may contact the display bezel, block part of the screen, or simply have nowhere to clamp. Choose a bracket that explicitly names the 13.4 inch display.
Trim names alone are not enough
AT4, Denali, Elevation, and HD trims did not all switch dashboards in the same model year. The screen size stated in the listing and the product photos are more reliable than a broad “fits Sierra” claim.
Best Mounting Location for Towing and Work Use
For towing, the ideal phone position is beside the infotainment display and below the top edge of the dashboard. This keeps navigation visible without adding another object in the windshield view, and it keeps the phone clear of trailer brake controls and the lower switch bank.
A multi device platform makes sense when the truck is also carrying a tire pressure monitor, radio, camera display, or dedicated GPS. Keep the heaviest device closest to the mounting base, use the shortest practical arm, and leave clear access to the hazard switch, climate controls, and display edges.
MagSafe or Spring-Loaded Cradle?
A magnetic mount is faster and cleaner, and it works best when the phone or case has a properly aligned magnetic ring and you remove the phone often. A spring loaded cradle is more forgiving with rugged cases, older Android phones, and devices without magnetic hardware.
For charging mounts, keep in mind that wireless charging can generate heat during navigation, especially in direct sunlight. A non-charging magnetic mount paired with a short USB-C cable is often the more reliable setup on a long towing day. Our MagSafe car mount guide covers magnet strength, case alignment, and placement in more detail.
GMC Sierra Phone Mount Rules of Thumb
- Match the mount to the screen size, not just the model year.
- Choose a custom metal bracket over a vent clip when one exists for your dashboard.
- Use the shortest possible arm to reduce vibration.
- Do not let the phone cover the infotainment display, hazard switch, trailer controls, or airbag area.
- Use a mechanical cradle for thick rugged cases unless the case has a strong magnetic ring.
- Recheck fasteners after the first week and after extended driving on rough roads.
Frequently Asked Questions
What is the best phone mount for a 2022 or newer GMC Sierra?
For a truck with the 13.4 inch display, a matching custom bracket such as the RERPRO or Kaishengyuan 13.4 inch mount is the best single phone option. It avoids the vents, requires no adhesive, and uses a short metal arm. Confirm the truck has the refreshed dashboard before ordering.
Will a Silverado phone mount fit a Sierra?
Often, yes. Silverado and Sierra trucks share major dashboard architecture, but trim panels and model year changes can affect fit. Only use a shared listing when it explicitly names the Sierra, your screen size, and your trim or dashboard generation.
What mount works in a 2014-2018 Sierra?
A quality windshield or dashboard suction mount is usually the simplest choice. The earlier dashboard has fewer widely available custom brackets. Keep the arm short and place it low enough that it does not obstruct your view through the windshield.
Is the RubiGrid worth it for one phone?
It can be, but it earns its keep when you plan to mount several devices or want room to expand later. For a single phone, a compact Kaishengyuan bracket is cleaner and simpler. RubiGrid is the better choice for a real command center setup.
Can I mount a tablet in the Sierra?
Use a multi device platform or a dedicated seat bolt mount built for the load. Do not hang a full size tablet from a standard vent clip. The weight and the strain it puts on a clip are too much for reliable use in a truck.
Bottom Line
The best GMC Sierra phone mount is the one built around the truck’s actual dashboard. Newer trucks with the 13.4 inch screen are best served by the RERPRO or Kaishengyuan 13.4 inch mount. Sierra models with the 7 or 8 inch display have a matching Kaishengyuan option, and the Bulletpoint RubiGrid is the strongest choice for a multi device work or overland setup. Owners of 2014-2018 trucks can rely on a well positioned suction mount instead of settling for a weak vent clip.
Do not guess based on year alone. Confirm the screen size, trim, and dashboard photo first. That check is the difference between a clean, factory-like install and another mount sitting unused in the center console.
