## Summary description

RAM Mounts Tough‑Ball mirror base designed for Harley‑Davidson motorcycles. Constructed from plastic and steel with a black metallic finish, it provides a compatible mounting point for mirror stems that use the Tough‑Ball system. Suited for replacing or upgrading OEM mirror bases to restore stable mirror positioning and vibration resistance on touring and cruiser bikes.

## Long description

RAM Mounts Tough‑Ball mirror base for Harley‑Davidson motorcycles provides a compatible mounting point for mirror stems that use the Tough‑Ball system. Constructed from plastic and steel with a black metallic finish, the unit includes a 1/4"-20 x 1" threaded stud integrated with a 1" diameter ball, a female blind barrel nut and a nylon washer. It is intended as a replacement or upgrade for OEM mirror bases to restore stable mirror positioning and reduce vibration on touring and cruiser bikes.
Advantages
The combination of durable plastic and steel components offers corrosion-resistant contact surfaces and structural strength while keeping weight low. The 1" Tough‑Ball interface enables compatibility with a wide range of RAM mounting arms and mirror stems designed for that system, providing predictable adjustment and firm retention. The included nylon washer helps dampen vibration between metal parts, and the blind barrel nut design simplifies installation into compatible mirror housings.
Suitable for
 Replacing worn or damaged OEM mirror bases on Harley‑Davidson touring and cruiser motorcycles
 Upgrading to the RAM Tough‑Ball mounting system for improved accessory compatibility
 Installing aftermarket mirrors that accept a 1" ball mount
 Maintenance projects requiring a stable, vibration‑resistant mirror mounting point
Key specifications

 Finish: black metallic
 Ball diameter: 1 inch (1")
 Thread: 1/4"-20 x 1" threaded stud
 Included parts: female blind barrel nut and nylon washer

How to use
Remove the existing mirror base according to the motorcycle manufacturer's service instructions. Insert the RAP‑B‑379‑HA1U threaded stud into the mirror housing or mounting hole and secure the blind barrel nut from the rear side as applicable. Position the nylon washer between mating surfaces if required to reduce vibration and prevent metal‑to‑metal contact. Attach a compatible mirror stem or RAM arm onto the 1" ball and tighten the clamp on the mating component to the manufacturer's recommended torque for the mounting system. Verify mirror alignment and re‑check fasteners after a short test ride.
Usage recommendations
For safe and reliable performance, use only mirror stems and mounting arms designed for the 1" RAM Tough‑Ball system. Periodically inspect the ball, washer and fasteners for wear or loosening, and retighten to specified torque values. If the motorcycle's mirror housing or threads are damaged, repair or replace those components before installing the mirror base to ensure secure mounting and correct alignment.
