4-40 Heavy Duty Swivel Ball Link (2 Pack) from Du-Bro - 899

The DU-BRO Heavy Duty Ball Links are built for RC hobbyists who want strong, smooth, and reliable linkage components. These ball links provide friction-free movement, making them perfect for control surfaces, steering systems, throttle linkages, and other areas where accuracy and durability are important. Each ball link uses a burnished, nickel-plated brass ball that rotates smoothly and resists wear. This gives you consistent, slop-free control even in high-stress models such as aerobatic airplanes, helicopters, RC cars, drones, and boats. The heavy-duty design ensures long-lasting performance, even under vibration or heavy load.

Every assembly includes everything you need for a secure installation:
Socket head cap screw
Brass shim
Nylon insert lock nut

These parts work together to provide a tight, vibration-resistant connection that stays secure through repeated flights and mechanical movement. Proudly Made in the USA, DU-BRO Heavy Duty Ball Links are trusted by RC builders for their strength, smooth operation, and long-term reliability. Whether you’re building a new model or replacing older hardware, these ball links deliver dependable performance you can count on.
