Mounting a phone to a snowmobile is a different problem from mounting one in a car. The vibration is more sustained and more violent than any road vehicle. The temperatures are well below what most phone mounts are designed for. And if it starts to snow while you are riding, your mount needs to keep the phone dry or the phone needs to be weatherproof enough to handle it on its own. A cheap plastic handlebar mount designed for a bicycle will crack, loosen, or simply fall apart in a cold, wet, high-vibration environment. This guide covers what actually works.
What to look for in a snowmobile phone mount
Metal construction. Plastic mounts become brittle in extreme cold and crack under vibration. The mounts on this page are all metal or high-strength composite with no cheap plastic components that will fail after a few hours on the trail.
Vibration resistance. Snowmobile engines produce significant vibration, particularly on rough terrain. Mounts with rubber ball-and-socket joints like the RAM system absorb vibration rather than transmitting it directly to the phone. This matters for both mount longevity and phone protection.
Cold weather grip. Standard spring-loaded cradles can lose grip in extreme cold as the spring tension changes. Make sure the cradle style you choose is rated or proven for cold weather use.
Waterproofing. You have two options: use an open mount and rely on your phone’s own water resistance (IP67 or IP68 rated phones handle snow well), or use a fully enclosed weatherproof case mount that physically seals the phone from the elements. Most modern flagship phones are rated IP67 or better, which is sufficient for snow riding. If you have an older or budget phone without a water resistance rating, use an enclosed mount.
Always use a tether. On a snowmobile, if the mount fails on rough terrain your phone is gone either into deep snow or onto hard ice. A tether from the phone to the handlebar is inexpensive insurance. RAM makes a dedicated X-Grip tether that works with all their cradles.

1. RAM X-Grip with U-Bolt Handlebar Base — best overall
The RAM X-Grip with U-Bolt Handlebar Base (RAM-B-149Z-UN7U) is a proven snowmobile phone mount. The U-bolt base bolts directly to the handlebar using included hardware and accommodates bars from 0.5 to 1.25 inches in diameter which covers virtually all snowmobile handlebars. The ball-and-socket double socket arm is made from powder-coated marine-grade aluminum and stainless steel components that handle cold, vibration, and moisture without degrading. The rubber ball joint absorbs vibration rather than transmitting it directly to the phone. The spring-loaded X-Grip cradle fits phones from 1.875 to 3.25 inches wide including most phones in standard cases. A device tether is included for the rugged use case where a dropped phone means a lost phone.
RAM backs this with a lifetime warranty. This is the same system used on military vehicles, marine applications, and emergency service vehicles. It will outlast your sled.

2. RAM X-Grip Large with Tough-Claw — best for large phones
The RAM X-Grip Large with Tough-Claw Snap-Link Base uses the same proven X-Grip cradle as above but swaps the U-bolt for a Tough-Claw clamp that installs without tools and requires no bolts or hardware. You just squeeze, position, and release. The large X-Grip cradle fits bigger phones up to 4.5 inches wide. Same marine-grade aluminum construction, same lifetime warranty. For riders who want a faster install or removal, the Tough-Claw is the right base. It grips rails and tubes from 0.625 to 1.5 inches in diameter and holds with the same security as a bolted U-bolt base under normal snowmobile conditions.

3. Quad Lock Handlebar Mount — best for cold weather phone performance
Quad Lock’s handlebar mount uses a dual-stage locking system that is significantly more resistant to vibration-induced movement than a spring-loaded cradle. The phone locks in with a deliberate twist and releases with a push of the lock tab. It does not rattle or shift under sustained vibration the way cradle mounts can. The handlebar clamp is precision-machined and adjustable for bar diameter.
The reason snowmobile riders specifically recommend Quad Lock over other systems for cold weather use is the wireless charging head option. The 15W Qi2 wireless charging head generates enough heat during charging to keep the phone’s battery performing normally well below freezing. This is a genuine advantage when a cold battery means a dead navigation screen in the middle of a trail. The Quad Lock poncho rain cover is also available for added weather protection.
Note that Quad Lock requires a compatible case or MAG case as the phone needs the Quad Lock adapter built in to attach to the mount. If you are already in the Quad Lock ecosystem this is the best snowmobile setup available.

4. iMESTOU Waterproof Enclosed Mount — best for non-waterproof phones
If your phone does not have an IP water resistance rating, the iMESTOU IP67 Waterproof Enclosed Mount physically seals your phone inside a rated housing. The handlebar clamp fits 7/8-inch, 1-inch, and 1.25-inch bars using included rubber rings. The PET touchscreen panel remains responsive and the anti-theft locking mechanism prevents the phone from being shaken out on rough terrain. Available in S (phones up to 6.1 inches) and L (phones up to 6.8 inches) — measure your phone against the listed dimensions before ordering.
The trade-off versus an open mount is reduced touch sensitivity through the plastic panel and some heat buildup during long rides. For riders with a modern IP67 or IP68 rated phone, an open RAM or Quad Lock mount is the better daily setup. For older phones or anyone who wants guaranteed waterproof protection regardless of phone specs, the iMESTOU is the right answer.

5. RAM X-Grip Tether — add this to any RAM setup
The RAM X-Grip Phone Tether connects your phone to the X-Grip cradle with a short safety leash. If the mount takes a hard hit and the phone comes loose, the tether keeps it from disappearing into deep snow or bouncing off hard-pack ice at speed. Inexpensive, takes 30 seconds to attach, and eliminates the worst-case scenario. Add this to any RAM X-Grip setup on a snowmobile as it is not optional in this environment.

Placement tips for snowmobile mounting
- Center handlebar position is best. Mounting at the center of the bar keeps the phone in your natural forward sightline and reduces the arc of movement the phone makes when the bars turn. Edge-mounted phones can sweep further out of view on sharp turns.
- Keep the screen angled slightly away from direct wind. On trail riding at speed, a screen directly facing into the wind creates significant glare and can ice up in wet conditions. Angle the phone slightly downward or use a sun/wind visor if your mount allows it.
- Use hand warmers or heated grips to manage cold. If your sled has heated grips, the handlebar position near the grip keeps the mount area marginally warmer than positions farther from the heat source. At extreme cold, keep the screen brightness high as a dim screen becomes impossible to read in glare.
- Pre-download your trail maps. Do not rely on cell signal on a trail. Download your trail map offline before you leave. Losing signal in the middle of a trail is an annoyance. Getting lost because you ran out of signal is a safety issue.
- Keep the phone charged. Cold batteries discharge faster. Start every ride with a full charge and consider a Quad Lock wireless charging head or a USB power bank in the glovebox for longer days on the trail.
Frequently Asked Questions
Can I use a motorcycle phone mount on a snowmobile?
Some motorcycle mounts work fine. Specifically all-metal RAM Mounts and Quad Lock, which are designed for vibration and weather. What does not work well on a snowmobile is any plastic motorcycle mount or a mount with plastic ball joints, which become brittle in extreme cold. Stick to metal construction and confirmed cold-weather-rated mounts.
Does cold weather affect my phone mount?
Yes. Plastic components become brittle and can crack. Spring tension in cradle-style mounts can change, reducing grip. Rubber components in RAM ball-and-socket mounts handle cold well. RAM mounts are rated for temperatures well below freezing and used in military and marine environments worldwide.
Do I need a waterproof case for snowmobile riding?
If your phone is IP67 or IP68 rated, an open mount in normal snow conditions is fine. Most current flagship iPhones and Android phones carry IP67 or better. If your phone has no water resistance rating, use the iMESTOU enclosed mount to protect it physically. Check your phone’s specs before riding in wet or heavy snow conditions.
Why does my phone screen stop working in the cold?
Below about 32°F, touchscreen responsiveness degrades and battery discharge accelerates. The Quad Lock wireless charging head is an effective solution as it generates heat during charging that keeps the phone operating normally in temperatures well below freezing. Keeping the phone inside your jacket during breaks and mounting it only when moving also helps preserve battery in extreme cold.
