The RAM Mounts Tough-Mag 66MM Diameter Ball Base is a magnetic mounting platform that combines a 66mm diameter high-strength magnet with a standard 1-inch RAM ball socket. This component allows riders to quickly attach and detach RAM Mounts compatible device holders using powerful magnetic force, eliminating the need for threaded connections or mechanical locks. The magnetic mounting system is ideal for riders who frequently swap devices or need rapid removal for security.

Key Features
Magnetic Quick-Release System: The 66mm diameter magnet provides strong holding force while allowing instant device removal without unscrewing or unlocking mechanisms, perfect for quick stops where you need to pocket your phone.
Universal RAM Ball Compatibility: The integrated 1-inch ball works with the entire RAM Mounts ecosystem, from phone cradles to GPS holders, giving you complete flexibility to swap devices on the same magnetic base.
Secure High-Strength Magnet: Engineered with rare-earth magnets that maintain grip through vibrations and road irregularities while still permitting deliberate removal when needed.
Compact 66mm Profile: The mid-size magnetic surface balances holding strength with space efficiency, fitting neatly on handlebars, tanks, or instrument clusters without dominating your cockpit.
Use Case Scenarios
- Daily commuters who need to quickly remove their phone at traffic lights or parking spots for security
- Touring riders running multiple devices (GPS, phone, action camera controller) who swap mounts throughout the day
- Riders who want theft-deterrent mounting that allows instant device removal when leaving the bike unattended
Why Choose the Tough-Mag 66MM?
- Instant attachment and removal takes under 2 seconds versus 10+ seconds for threaded or locking mounts
- Works with your existing RAM phone holders, GPS mounts, and device cradles without buying new holders
- The 66mm size provides the ideal balance between holding strength and weight for smartphones and compact GPS units
- Marine-grade construction from RAM Mounts ensures corrosion resistance in monsoon conditions and coastal humidity
Pros & Considerations
Pros:
- Fastest device removal system in the RAM catalogue – true one-handed quick release
- No wear parts or mechanical failure points unlike spring-loaded or threaded systems
- Magnet strength is unaffected by dust, mud, or water exposure that can jam mechanical locks
Considerations:
- Requires a Tough-Mag top plate on your device holder (sold separately) – not compatible with standard RAM holders without the magnetic adapter
- The 66mm size is best for lighter devices – heavier GPS units or tablets may require the 88mm Tough-Mag for maximum stability on rough roads
Frequently Asked Questions
Q: Will the magnet hold my device on rough roads and potholes?
A: Yes. The 66mm rare-earth magnet is designed to maintain grip through normal riding vibrations and road irregularities. It will hold smartphones and compact GPS units securely. However, extreme off-road use or very heavy devices may benefit from the larger 88mm Tough-Mag variant.
Q: Can I use my existing RAM phone holder with this magnetic base?
A: Not directly. Your existing RAM holder needs a Tough-Mag adapter plate (sold separately) that attaches to the back of the holder. Once the adapter is installed, any RAM holder becomes Tough-Mag compatible with this base.
Q: How do I attach the 66mm magnetic base to my motorcycle?
A: This product is the ball base only. You need a RAM mounting arm and a surface mount (handlebar clamp, mirror mount, or adhesive base) to complete the system. The 1-inch ball socket connects to standard RAM arms.
Q: Will the magnet interfere with my phone’s GPS or compass?
A: Modern smartphones use GPS satellites for navigation, which are not affected by magnets. Some compass apps may show slight deviation when the phone is directly on the magnet, but GPS-based navigation apps (Google Maps, Waze) work perfectly.
Q: What’s the difference between the 66mm and 88mm Tough-Mag bases?
A: The 88mm version has a larger magnet diameter providing stronger holding force for heavier devices or more aggressive riding. The 66mm is ideal for smartphones and compact GPS units, while the 88mm suits larger GPS units, tablets, or off-road riding where extra grip is needed.
